Introduction
Alt-N Technologies' MDaemon Messaging Server is a standards-based SMTP/POP3/IMAP mail server that supports Windows 7/Vista/XP/2008/2003 systems and offers a full range of mail server functionality. MDaemon is designed to manage the email needs of any number of individual users and comes complete with a powerful set of integrated tools for managing mail accounts and message formats. MDaemon offers a scalable
SMTP, POP3, and IMAP4 mail server complete with LDAP and Active Directory support, an integrated browser-based email client, content filtering, spam filters, extensive security features, and more.
MDaemon Lite and Pro
MDaemon Messaging Server is generally available in two versions: MDaemon Lite and
MDaemon Pro. With the powerful features of MDaemon Lite, you can host your network's email with MDaemon's full-fledged SMTP server, or you can collect your entire domain's email from a single ISP provided POP3 mailbox via the included
DomainPOP feature. You can also host multiple Mailing Lists, allow your users to access their email via the included WorldClient webmail component, and utilize a number of other features. MDaemon Pro is equipped with everything in Lite, plus its support for
IMAP4, multiple domains, Domain Sharing, Gateways, expanded Mailing Lists, and
BlackBerry smartphone integration make it ideal for larger organizations with greater needs. MDaemon Pro also adds group calendar and scheduling, an instant messaging system, multiple language support for WorldClient, automatic domain gateway creation, and more. For a detailed comparison chart outlining the features included in each version, visit: www.altn.com

MDaemon Private Cloud
MDaemon Private Cloud (MDPC) is a special edition of the MDaemon Messaging Server that was developed specifically for resellers and IT Service providers who wish to use
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
13
MDaemon software to provide hosted email services to their customers. Unlike
MDaemon Lite and Pro, which are sold for on-premise use, MDPC was built on a new licensing and code foundation specifically designed for use in a hosted environment.
MDaemon Private Cloud includes all MDaemon Pro features and the following additional features:
New licensing and billing (per-user/per-month)
Outlook support
Improved multi-domain control
Per-domain branding (white label)
Per-domain reporting
Non-billable user test accounts (counts will not be included in total billing counts)
Commtouch Outbreak Protection and Antivirus and the ClamAV antivirus engine
(optional with additional cost)
ActiveSync for MDaemon (optional with additional cost)
MDaemon Features
MDaemon is equipped with many features besides SMTP, POP3, and IMAP4 email processing. The following is a list of just some of those features.
MDaemon Pro includes a fully integrated BlackBerry® Enterprise Server, which makes it possible for your users to synchronize their MDaemon email, calendar, contacts, and other PIM data with a
15
.
Complete support for virus scanning and protection is available as an add-on to your MDaemon Private Cloud license. This provides access to Commtouch's realtime
456
and
451
technology and the
462 antivirus engine. Messages can then be scanned for viruses and cleaned or deleted automatically before ever reaching the intended recipients. Further, you can configure MDaemon to send a message to the administrator, sender, and recipient of the infected message notifying them of the virus.
MDaemon features a complete suite of Mailing List or email group management functions allowing for the formation of an unlimited number of distinct distribution lists that can contain local and/or remote members. Lists can be set to allow or refuse subscription requests, be public or private, post replies to either the list or the originator of the message, be sent in digest format, and be configured using numerous other features.
An integrated component of MDaemon is
258
. This exciting product makes it possible for your users to access their email using their favorite web browser rather than from a workstation dependent email client. This tool is perfect for mobile staff and users who do not have a dedicated machine from which to access their email.
WorldClient is equipped with a complete suite of email client features. You can: send and receive email, spell check messages, manage your email in multiple personal folders, display the interface in any of 18 languages, schedule meetings and appointments and share calendars and tasks with other users, manage your
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
14 MDaemon Messaging Server 17.0
MDaemon account settings (when used in conjunction with
286
), manage contacts, and more. WorldClient is also equipped with
259
, a small utility that can be downloaded and installed on a user's local computer. This provides easy access to your email and folders and checks for new messages without having to open your web browser. It also includes a complete Instant Messaging system that can be used to quickly "chat" with other MDaemon/WorldClient users.
MDaemon is equipped with many features designed to help you make your email system secure. The Spam Filter and DNS Black Lists features will help you put an end to most "spam" email messages that "spammers" try to route through or to your domain. IP and Host Screening and the Address Blacklist provide the capability to screen and prevent certain addresses and domains from connecting to or sending mail through your system. They also make it possible to connect to specific IP addresses while screening all others.
Equipped with support for Lightweight Directory Access Protocol (LDAP),
MDaemon can keep your LDAP server up to date on all of its user accounts. This makes it possible for you to keep an LDAP address book up to date so that users with email clients that support LDAP can access it. You can also choose to use
Active Directory or your LDAP server as the MDaemon account database instead of an ODBC compliant database or the local USERLIST.DAT system. Thus, you can configure multiple MDaemon's at different locations to share the same account database.
MDaemon's extensive parsing features make it possible to provide email for an entire LAN with as little as a single dial-up ISP POP3 mailbox. This makes it possible to provide email to an entire network for a fraction of the normally associated cost.
MDaemon can be configured to keep your Windows Address Book or Microsoft
Outlook Contact Store up to date with your user information. This provides another means of making a global address book available to your users.
Address Aliases provides the ability to route email messages addressed to
"fictitious" mailboxes to a valid account or mailing list. This makes it possible for individual accounts and lists to have multiple email addresses at one or more domains.
The Domain Gateways feature provides the option of setting up separate domains for various departments or groups that may be local to your network or located somewhere else on the Internet. Using this feature, all mail addressed to a domain for which MDaemon is acting as a gateway will be placed in that domain's mailbox by MDaemon. It can then be collected by that domain's
MDaemon server or email client and distributed to the domain's users. This feature can also be used to enable MDaemon to act as a backup mail server for other domains.
Accounts can be controlled remotely by users by using specially formatted email messages. This allows greater administrative flexibility, and empowers users by turning day-to-day simple account maintenance tasks, such as changing passwords, over to them.
Integrated web-based remote administration. MDaemon's
286
component is integrated with MDaemon and WorldClient and enables your users to review and edit their account settings via their web-browser. You can
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
15
designate which settings that your users may edit, and assign access permissions on a per account basis. Remote Administration can also be used by the Administrator (and whomever else you wish to allow) to review or edit any of
MDaemon's settings and any other files that you wish to make available to the
Remote Administration system for reviewing.
With File Catalogs, the email administrator can create password protected groups of files which users can have encoded and automatically sent to them through the use of specially formatted email messages.
An internal message transport system known as RAW mail provides a simple method for placing messages into the mail stream and greatly simplifies custom mail software development. Using RAW, a complete mail system can be devised using a simple text editor and a couple of batch files.
A highly versatile Content Filtering system makes it possible for you to customize server behavior based on the content of incoming and outgoing email messages.
You can insert and delete message headers, add footers to messages, remove attachments, route copies to other users, cause an instant message to be sent to someone, run other programs, and more.

XMPP
306
WorldClient Instant Messenger
259
(WCIM)
WCIM now uses the XMPP protocol for instant messaging instead of WorldClient's proprietary protocol. This allows the WCIM desktop client to communicate not only with other WCIM clients, but any third-party XMPP clients (including mobile clients) connected to your MDaemon's XMPP server. Additionally, WCIM now has two types of connections: "WCMailCheck" and "WCIMXMPP." WCMailCheck connects to WorldClient for new mail notifications and message counts. WCIMXMPP connects to the XMPP server for instant messaging. Consequently, WCIM users will now have an entry for each type of connection listed on the Connections screen of the client (e.g.
"Example.com Mail" and "Example.com WCIM"). When updating to version 17, WCIM will automatically create a WCIMXMPP connection to go with your already existing
WCMailCheck connection, and it will migrate your IM contacts from the old system to
XMPP. The look and feel of the new WCIM client is essential the same, but there are some differences, such as how contacts and group chats are managed. See the WCIM client's Help system for more info about what has changed.
WorldClient Dropbox Integration
279
WorldClient is new equipped with direct support for Dropbox, which allows your users to save file attachments to their Dropbox accounts, and to insert direct links to Dropbox files in outgoing messages. To provide this feature to your WorldClient users, you must
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
17
set up your WorldClient as a Dropbox app on the Dropbox Platform . This is a simple process, requiring you only to sign in to a Dropbox account, create a unique name for an app with Full Dropbox access, specify the Redirect URI to WorldClient, and change one default setting. Then, you will copy and paste the Dropbox App Key and App
Secret from there to the options on Dropbox screen in MDaemon. After that your users will be able to link their Dropbox accounts to WorldClient when they next sign in to
WorldClient. For step-by-step instructions on how to create your Dropbox app and link it to WorldClient, see:
Creating and Linking Your Dropbox App
281
.
When you create your Dropbox app it will initially have "Development" status. This allows up to 500 of your WorldClient users to link their Dropbox accounts to the app.
According to Dropbox, however, "once your app links 50 Dropbox users, you will have two weeks to apply for and receive Production status approval before your app's ability to link additional Dropbox users will be frozen, regardless of how many users between 0 and 500 your app has linked." This means that until you receive production approval,
Dropbox integration will continue to work but no additional users will be able to link their accounts. Obtaining production approval is a straightforward process to ensure that your app complies with Dropbox's guidelines and terms of service. For more information, see the Production Approval section of the Dropbox Platform developer guide .
Once your WorldClient app is created and configured properly, each WorldClient user will be given the option to connect their account to their Dropbox account when they sign in to WorldClient. The user is required to log in to Dropbox and grant permission for the app to access the Dropbox account. Then the user will be redirected back to
WorldClient using a URI that was passed to Dropbox during the authentication process.
For security that URI must match one of the Redirect URIs you specified on your app's info page at Dropbox.com. Finally, WorldClient and Dropbox will exchange an access code and access token, which will allow WorldClient to connect to the user's Dropbox account so that the user can save attachments there. The exchanged access token expires every seven days, meaning that periodically the user must reauthorize the account to use Dropbox. Users can also manually disconnect their account from
Dropbox, or reauthorize it when necessary, from the Cloud Apps options screen within
WorldClient.
MDaemon Health Check
MDaemon is now equipped with a new troubleshooting utility called MDaemon Health
Check, located at: MDaemon\App\MDHealthCheck.exe. It can be launched from the
MDaemon UI using a new toolbar button or the new menu item under the Help menu.
Click Analyze on the MDaemon Health Check interface to have it scan MDaemon's security-related settings (AV, SPAM, SSL, etc.) to find settings that are not recommended. All non-recommended settings are then displayed on the screen. Each entry contains the name of the setting, its current value, the recommended value, and the location in MDaemon where that setting can be found. You can then select any entries you wish to change to the recommended value and click Set to Recommended to have MDaemon change them for you. Finally, MDaemon Health Check also creates a log file of the analysis and places it in MDaemon\Logs. The log includes the current value of all the analyzed settings and any warnings or errors found. There is an Open
Log button for displaying the last log generated.
Integration with Let's Encrypt via PowerShell script
To support
563
for
565
,
568
, and
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
18 MDaemon Messaging Server 17.0
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

Option to store mailbox passwords using non-reversible encryption
There is a new
724
to store mailbox passwords using non-reversible encryption. This protects the passwords from being decrypted by MDaemon, the administrator, or a possible attacker. When enabled, MDaemon uses the bcrypt password hashing function, which allows for longer passwords (up to 72 characters), and for passwords to be preserved yet not revealed when exporting and importing accounts. Some features, however, are not compatible with this option, such as weak password detection and APOP & CRAM-MD5 authentication, because they depend on
MDaemon being able to decrypt passwords. Non-reversible passwords is disabled by default.
ActiveSync Client Approval
There is a new ActiveSync setting that you can use to require that "New clients must be authorized by an administrator prior to synchronizing" with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the
339
and
642 client settings screens. The global option is Off by default and the account option is set to "Inherit."
ActiveSync Notifications
Two types of administrative notifications have been added to ActiveSync: Sync
Rollback Notifications and Corrupt Message Notifications.
Sync Rollback Notifications
The ActiveSync Service can now notify the administrators if a client is repeatedly/ frequently sending expired Sync Keys in Sync operations.
These merely inform the admin that the server issued a rollback for a given collection because a client made a sync request with the most recently expired
Sync Key. The subject states "ActiveSync Client Using expired Sync Key". This could occur because of a network issue or something about the content previously sent to the client in that collection. In some cases, the item ID will be there, it merely depends upon whether or not the previous sync on that collection sent any items.
Rollback warnings do not mean the client is out of Sync, it means that the client has the potential to go out of Sync and our internal system detected it. Rollback warnings are issued for a collection no more than once per 24 hour period.
[System] SendRollbackNotifications=[0|1|Yes|No|True|False]
[System] RollbackNotificationThreshhold=[1-254] : The number of rollbacks that must occur on a given collection prior to a notification being sent to the admin. We recommend a value of at least 5 here, since Network hiccups play a part in this.
[System] RollbackNotificationCCUser=[0|1|Yes|No|True|False] : Whether or not to CC the user whose client sent that expired Sync Key.

20 MDaemon Messaging Server 17.0
ActiveSync Corrupt Message Notifications
The ActiveSync Service can now notify the administrators if a particular message cannot be processed. These are sent in real time to inform the admin of a mail item that could not be parsed and that further action on this item is not possible. The subject states "Corrupt message notification". These items, in previous versions, could lead to a crash. In most cases, the content of the msg file will not be MIME data. If it is MIME data, it is likely corrupt. You can choose to CC the affected user of these notifications with the CMNCCUser key so that they are aware that an email has arrived in their mailbox that is un-readable. The appropriate action for these is to move the designated msg file from the user's mailbox and analyze it to determine both why it is not able to be parsed and how it came to exist in the state that it is in.
[System] CMNCCUser==[0|1|Yes|No|True|False]
Additional Features and Changes
MDaemon 17.0 has many more new features and changes. See RelNotes.html located in MDaemon's \Docs\ subfolder for a complete list of all new features, changes, and fixes to MDaemon from the previous version.
New in MDaemon Private Cloud 4.5
MDaemon Private Cloud 4.5 includes MDaemon 16.5.2 and Outlook Connector
4.0.1.
For ClamAV plugin added option to quarantine files that cannot be scanned. Also added an option to allow password-protected files that cannot be scanned. If non-scanned files are allowed through "X-CAV-Result:" header results could contain "encrypted" (password-protected file), "non-scan" (could not be scanned), or "scanning error" (error during scan).

MDPGP Improvements
465
Key Server Support
WorldClient
WorldClient can now act as a basic public-key server. Enable the new MDPGP option to
"Send public-keys over HTTP (WorldClient)" and WorldClient then will honor requests for your users' public-keys. The format of the URL to make the request looks like this:
"http://<WorldClient-URL>/WorldClient.dll?View=MDPGP&k=<Key-ID>". Where
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
21
<WorldClient-URL>
is the path to your WorldClient server (for example, "http:// wc.example.com
") and <Key-ID> is the sixteen character key-id of the key you want
(for example, "0A1B3C4D5E6F7G8H"). The key-id is constructed from the last 8 bytes of the key fingerprint - 16 characters in total.
DNS (PKA1)
Enable the new MDPGP option to "Collect public-keys from DNS (pka1) and cache for
[xx] hours" if you want MDPGP to query for message recipient public-keys over DNS using PKA1. This is useful because it automates the process of obtaining some recipients' public keys, preventing you or your users from having to obtain and import them manually in order to send encrypted messages. When PKA1 queries are made, any key URI found is immediately collected, validated, and added to the key-ring. Keys successfully collected and imported to the key-ring using this method will automatically expire after the number of hours specified in this option or according to the TTL value of the PKA1 record that referred them, whichever value is greater.
Key Handling
Tracking Keys
MDPGP now always tracks keys by their primary key-ids rather than sometimes by the key-id and other times the sub-key-id. Consequently, the MDPGP dialog's list of keys was cleaned up to remove two unnecessary columns. Further, MDPGP now more strictly controls the contents of its "exports" folder. As a result you will always find exported copies of local user keys there. Even though the private keys are encrypted, for extra security you should use OS tools to protect this folder (and indeed the entire PEM folder structure) from unauthorized access.
Preferred Keys
Previously, when multiple different keys for the same email address were found in the key-ring, MDPGP would encrypt messages using the first one that it found. Now you can right-click on any key and set it as preferred, so that MDPGP will use that key when multiple keys are found. If no preferred key is declared, MDPGP will use the first one found. When decrypting a message MDaemon will try each one.
Disabled Keys
Disabled and deleted keys are now tracked in a new file called oldkeys.txt.
Previously, disabled keys were tracked in the plugins.dat file.
MDPGP Signature Verification
MDPGP can now verify embedded signatures found within messages that are not encrypted. Previously it was not able verify signatures unless the message was both signed and encrypted. When viewing a message with a verified signature in WorldClient, a new icon is displayed to indicate it was verified. Signature verification is enabled by default for all non-local users, or you can specify exactly which email addresses can and cannot use the service (see: "Configure exactly who can and can not use MDPGP
services" on the
465
).

22 MDaemon Messaging Server 17.0
XMPP Instant Messaging Server
306
MDaemon is now equipped with an Extensible Messaging and Presence Protocol (XMPP) server, sometimes called a Jabber server. This allows your users to send and receive instant messages using third-party XMPP clients , such as Pidgin , Gajim , Swift and many others. Clients are available for most operating systems and mobile device platforms.
MDaemon's XMPP instant messaging system is completely independent of MDaemon's
WorldClient Instant Messenger chat system; the two systems cannot communicate with each other and do not share buddy lists.
The XMPP server is installed as a Windows service, and the default server ports are
5222 (SSL via STARTTLS) and 5223 (dedicated SSL). The XMPP server will use
MDaemon's SSL configuration if it is enabled in MDaemon. Also, some XMPP clients use
DNS SRV records for auto-discover of host names. Please refer to http://wiki.xmpp.org/ web/SRV_Records for more information.
Users sign-in through their chosen XMPP client using their email address and password.
Some clients, however, require the email address to be split into separate components for signing in. For example, instead of "[email protected]," some clients require you to use "frank" as the Login/Username and "example.com" as the Domain.
For multi-user/group chat service, clients typically display this as "rooms" or
"conferences." When you want to start a group chat session, create a room/ conference (giving it a name) and then invite the other users to that room. Most clients don't require you to enter a server location for the conference; you only need to enter a name for it. When you are required to do so, however, use
"conference.<your domain>" as the location (e.g. conference.example.com). A few clients require you to enter the name and location together in the form:
"room@conference.<your domain>" (e.g. [email protected]).
Some clients (such as Pidgin ), support the user search service, allowing you to search the server for users by name or email address, which makes adding contacts much easier. Usually you will not have to provide a search location, but if asked to do so, use
"search.<your domain>" (e.g. search.example.com). When searching, the % symbol can be used as a wildcard. Therefore you could use "%@example.com" in the email address field to display a list of all users with an email address ending in
"@example.com."
Centralized Management of OC Client Settings
321
Use the OC Client Settings dialog to centrally manage the client settings of your
Outlook Connector users. Configure each screen with your desired client settings and
MDaemon will push those settings to the corresponding client screens as necessary, each time an Outlook Connector user connects to the server. The OC Client Settings are only sent to clients when one of the settings has changed since the last time the client connected and received them. If you enable the provided option to "Allow OC
users to override pushed settings," users can override any pushed settings on their individual clients. If that option is disabled, then all of the client screens are locked;
Outlook Connector users can make no changes.
To allow for certain settings that must be different for each user or domain, OC Client
Settings supports macros such as $USERNAME$, $EMAIL$, and $DOMAIN$. These macros will be converted to data specific to the user or domain when pushing settings to a
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
client. Take care not to place any static values in any fields that should use a macro, such as putting something like "Frank Thomas" in the Your Name field. To do so would cause every Outlook Connector user who connects to MDaemon, to have his or her name set to "Frank Thomas." For your convenience there is a Macro Reference button on the
323
screen, which displays a simple list of the supported macros.
For those using MDaemon Private Cloud (MDPC), there is another OC Client Settings dialog on the
152
, for controlling the Outlook Connector client settings on a per domain basis.
This feature is disabled by default, and works only for those using Outlook Connector client version 4.0.0 or higher.
"From:" Header Protection/Modification
559
This new security feature modifies the "From:" header of incoming messages to cause the name-only portion of the header to contain both the name and email address. This is done to combat a common tactic used in spam and attacks where the message is made to appear to be coming from someone else. When displaying a list of messages, email clients commonly display only the sender's name rather than the name and email address. To see the email address, the recipient must first open the message or take some other action, such as right-click the entry, hover over the name, or the like. For this reason attackers commonly construct an email so that a legitimate person or company name appears in the visible portion of the "From:" header while an illegitimate email address is hidden. For example, a message's actual "From:" header might be,
"Honest Bank and Trust" <[email protected]>, but your client might display only "Honest Bank and Trust" as the sender. This feature changes the visible portion of the header to display both parts, with the email address given first. In the above example the sender would now appear as
"[email protected] -- Honest Bank and Trust,"
giving you a clear indication that the message is fraudulent. This option only applies to messages to local users, and it is disabled by default.
Improved IP Screening
550
The IP Screen now contains an Import button that you can use to import IP address data from an APF or .htaccess file. MDaemon's support for these files is currently limited to the following:
"deny from" and "allow from" are supported only IP values are imported (not domain names)
CIDR notation is allowed but partial IP addresses are not.
Each line can contain any number of space-separated or comma-separated IP addresses. For example, "deny from 1.1.1.1 2.2.2.2/16", ""3.3.3.3, 4.4.4.4,
5.5.5.5", and the like.
Lines starting with # are ignored.
Automatic Installation of Product Updates
420
Using the Automatic Updates features you can configure MDaemon to inform the postmaster whenever an update is available for one of your installed products, or you

can download and install updates automatically. This includes MDaemon, SecurityPlus, and Outlook Connector. Automatically installing updates can be controlled separately for each product, and a server reboot is required each time an update is installed.
Installer files are downloaded when the update is detected, but the installation and reboot occur later at whichever hour you have designated. All installation activity is logged in the MDaemon system log, and the postmaster is informed after an update has occurred. See the
420
dialog for more information.
WorldClient Changes
285
WorldClient supports categories for email in the LookOut and WorldClient themes. Users can add the Categories column to the message list by going to "Options » Columns" and checking "Categories" in the Message List section. To select categories for one or multiple messages, select the messages and right-click one of them. Use the context menu to set the category.
Administrators can create custom categories. There are two files for this purpose: DomainCategories.json and PersonalCategories.json.
Domain Categories are enabled globally by default. To disable them open
MDaemon\WorldClient\Domains.ini
, and in the [Default:Settings] section change the value of "DomainCategoriesEnabled=" from "Yes" to "No".
Users are able to add and edit their own categories by default. If you wish to disable this option, you can do so per user or globally by changing the value of
"CanEditPersonalCategories=" from "Yes" to "No". The user option is located in the [User] section of the User.ini file and the global option is in the
Domains.ini
file under the [Default:UserDefaults] section.
If Domain Categories are enabled, and a user is not allowed to edit personal categories, the user will only see the categories listed in
DomainCategories.json
.
If Domain Categories are disabled, and a user is not allowed to edit personal categories, the user will see the categories listed in PersonalCategories.json.
The file CustomCategoriesTranslations.json is used to support your custom category names in multiple languages. Add any necessary custom category translatations to that file to make it possible for WorldClient to recognize a category saved to an event, note, or task in one language as the equivalent category in another language.
For more detailed information relating to the files mentioned here, see: MDaemon
\WorldClient\CustomCategories.txt
.
285
You can now hide the White List and Black List folders for WorldClient users by default.
To do so, open MDaemon\WorldClient\Domains.ini, and under
[Default:UserDefaults]
change the value of "HideWhiteListFolder=" or
"HideBlackListFolder=" from "No" to "Yes". You can hide or show these folders for specific users by editing those same keys in the User.ini file under the [User] section.

Check for Attachments
In the LookOut and WorldClient themes there is now an option to check a composed message for attachments before sending, when attachments are mentioned in the subject or body of the message. This can help you avoid accidentally sending a message without an attachments when it is supposed to include one.
607
You can now control whether or not accounts are allowed to use or required to use
Two-Factor Authentication (2FA). There are two new options on the
673 template for controlling the default settings for new accounts, and there are corresponding options on the
607
screen for controlling 2FA for individual accounts.

MDaemon Remote Administration (MDRA) UI Update
The user interface for MDRA no longer uses frames and has been updated to use a mobile first responsive design. Browser support is limited to IE10+, the latest Chrome, the latest Firefox, and the latest Safari on Mac and iOS. Android stock browsers have been known to have issues with scrolling, but Chrome on Android devices works well.
This design is based entirely on the size of the window being used. Whether the user is on a phone, tablet, or PC, the appearance is the same for the same window size. The most important change here is the menu. From 1024 pixels width and below, the menu is hidden on the left side of the browser. There are two methods that can be used to display the menu. If a touch device is in use, swiping to the right will show the secondary menu. Whether or not the device is in use, there is also a "menu" button in the top left corner that will display the secondary menu. Tapping or clicking the menu title with the left arrow next to it at the top of the menu will display the primary menu.
The help, about, and sign out menu in the top right corner changes based on the width of the screen as well. From 768 pixels and above, the words Help, About, and Sign Out are displayed. From 481 pixels to 767 pixels, only the icons are displayed. 480 pixels and below displays only a "gear" icon which when clicked or tapped will display a drop down menu with the Help, About, Sign Out options. List views with more than one

column have column on/off buttons that are accessed by clicking or tapping the gray right arrow button on the far right of the toolbar container. The settings pages are no longer designed to be exact copies of the MDaemon GUI, but are instead designed to reposition and resize based on the width/height of the browser.
Spambot Detection
562
(MDaemon PRO only)
A new feature called Spambot Detection tracks the IP addresses that every SMTP MAIL
(return-path) value uses over a given period of time. If the same return-path is used by in an unusual number of IP addresses in a short period of time, this may indicate a spambot network. Although it could still be a legitimate use of the mail system, experimentation has shown that this can be effective in limited cases at detecting a distributed spambot network as long as the same return-path is utilized throughout. If a spambot is detected, the current connection to it is immediately dropped and the return-path value is optionally blacklisted for a length of time you specify. You can also optionally blacklist all the spambot IPs then known for a user-defined period.
CardDAV
301
(MDaemon PRO only)
MDaemon now supports synchronizing contacts via the CardDAV protocol. MDaemon's
CardDAV server allows an authenticated CardDAV client to access the contact information that is stored in MDaemon. Notable CardDAV clients are Apple Contacts
(included with Mac OS X), Apple iOS (iPhone), and Mozilla Thunderbird via the SOGO plugin . For more information on CardDAV and configuring CardDAV clients, see:
301
.
Two Factor Authentication for WorldClient and Remote
Administration
MDaemon now supports Two Factor Authentication (i.e. 2-Step Verification) for users signing into WorldClient or MDaemon's Remote Administration web-interface. Any user who signs into WorldClient via HTTPS can activate Two Factor Authentication for the account on the Options » Security screen. From then on the user must enter a verification code when signing into WorldClient or Remote Administration. The code is obtained at sign-in from an authenticator app installed on the user's mobile device or tablet. This feature is designed for any client that supports Google Authenticator.
ActiveSync Protocol Migration Client
MDaemon now includes an ActiveSync protocol based Migration Client (ASMC.exe). It supports migrating mail, calendars, tasks, notes, and contacts from ActiveSync servers that support protocol version 14.1. Documentation for it can be found in the \MDaemon
\Docs
folder.
XML API for Management Tasks
MDaemon now ships with an XML over http(s) based API. The result of this is that
MDaemon Management clients can be written using any language on any platform that can make http(s):// post requests to the server. In MDaemon Pro, this is only available to authenticated Global Admins, but in MDaemon Private Cloud a subset of the available operations is accessible to authenticated domain admins as well. The API also produces a website with documentation on the API specification. The installation default is to

27
have it installed at http://servername:RemoteAdminPort/MdMgmtWS/, however, this can be set to any url for the sake of additional security.
The available operations include:
Help

SetAddressRestriction
GetAddressRestriction
At this time, command line management clients have been written/tested in Javascript,
Powershell, VBScript, C, C++ and Visual Basic. A simple HTML and Javascript test site has been used as a proof of concept for a web based management console that operates within several popular browsers. While not tested yet, it is fully expected that this API should work fine from web servers using PHP, Perl, and other development platforms.

MDPGP Provides OpenPGP Support (MDaemon PRO only)
465
OpenPGP is an industry standard protocol for exchanging encrypted data, and there are a variety of OpenPGP plugins for email clients that make it possible for users to send and receive encrypted messages. MDPGP is MDaemon's integrated OpenPGP component that can provide encryption, decryption, and basic key management services for your users without requiring them to use an email client plugin.
MDPGP encrypts and decrypts emails using a public-key/private-key system. To do this, when you wish to use MDPGP to send a private and secure message to someone,
MDPGP will encrypt that message using a "key" that you previously obtained from that person (i.e. his "public key") and imported into MDPGP. Conversely, if he wishes to send a private message to you, then he must encrypt the message using your public key, which he obtained from you. Giving the sender your public key is absolutely necessary, because without it he can't send you an OpenPGP encrypted message. Your unique public key must be used to encrypt the message because your unique private key is what MDPGP will use to decrypt the message when it arrives.
In order for MDPGP to manage signing, encrypting, and decrypting messages, it maintains two stores of keys (i.e. keyrings)—one for public keys and one for private keys. MDPGP can generate your users' keys automatically as needed, or you can create
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
them manually for specific users. You can also import keys that were created elsewhere. Further, MDaemon can look for public keys attached to authenticated messages from local users, and then import those keys automatically. That way a user can request a public key from someone and then email that key to himself so that
MDPGP will detect it and then import it into the public keyring. Finally, whenever a message arrives for an address that has a key in a keyring, MDPGP will sign, encrypt, or decrypt the message as needed, according to your settings.
You can configure MDPGP's signing and encryption services to operate either automatically or manually. When set to operate automatically, MDPGP will automatically sign and encrypt messages whenever possible. When set to operate manually, MDPGP will only sign or encrypt a message when the sending user inserts a special command into the message's Subject. In any case messages will only be signed or encrypted (or decrypted) when the account has been given permission to use those services.
Do Not Disturb
663
Do Not Disturb is a new
663
that makes it possible for you to schedule a time frame during which an account may not send mail or be accessed by its users. Access during a Do Not Disturb period is not allowed and returns an appropriate error response to IMAP, POP, SMTP, ActiveSync, and WorldClient access requests. MDaemon will still accept incoming mail for accounts in this state, but those accounts may not send mail or be accessed by mail clients.
ActiveSync Redesigned
335
The ActiveSync for MDaemon interface was completely redesigned, and there are a variety of new features and policy options available. You can manage ActiveSync under
335

WorldClient Improvements
Modernized the LookOut theme's icons and colors, and made some adjustments to its layout. There is also a new gray color style, although the default style is blue. The "New" button was moved to where the user's email address was previously located, and the email address is now in the top navigation bar. The
Help and Sign Out options were moved to a drop-down list beneath user's address, like in the WorldClient theme. Finally, the Options icon was moved to

29
30 MDaemon Messaging Server 17.0
the far right in the navigation bar.
WorldClient now supports adding inline images to a user's signature.
Merged Categories and Labels into just Categories. Users can now add, edit, and delete categories from a predefined list based on the old labels and categories.
Each category has a color associated with it. More than one category can be associated with a given color, but only one category with a specific name may exist. There are 26 colors to choose from (including white) which match Outlook category color options. If an event, task, note, or contact already has categories associated with it, but they don't match the predefined categories, their colors will be white until the user adds them to the predefined list of categories. If there is already a label associated with an event, the user can choose to remove the label and add a category, or leave the label. Old labels are not lost on upgrade.
WorldClient and LookOut themes - Desktop notifications are now available. When
LookOut or WorldClient loads, the browser will prompt the user on whether or not to allow desktop notifications. If the user chooses to allow them, then the user will receive notifications of new email messages, new instant messages (in the case that the corresponding chat is not in focus), and any change in status of a chat buddy. Desktop notifications are not supported by Internet Explorer.
WorldClient and LookOut themes - Added ability to view pdf files in the browser
(not supported in IE8). This is available in any document folder and any message that has a pdf file.
There is now a
282
in WorldClient. When this feature is enabled, users who have permission to
607
will be able to enter an alternate email address in WorldClient, which can be sent a link to reset their password if they forget it. To set up this feature, users must enter both the password recovery email address and their current password in WorldClient on the Options » Personalize page. Once set, if the user attempts to log in to
WorldClient with an incorrect password a "forgot password?" link will appear. This link takes them to a page that asks them to confirm their password recovery email address. If entered correctly, an email will be sent with a link to a change password page.
LookOut and WorldClient themes - added buttons and context menu items for users to create a new event, task, or note from the contents of a message.
Lite, LookOut, and WorldClient themes now attempt to detect and use the language currently being used by the browser.
LookOut and WorldClient themes - users can now use the browser's back and forward buttons to navigate in the main window
LookOut and WorldClient themes - Virtru can now be disabled by the admin on a per user basis by adding VirtruDisabled=Yes to the [User] section of the user's WC\User.ini file.
WorldClient theme - added a "Today" button to the calendar view buttons.
LookOut and WorldClient themes - users can now sort by the Description,
Location, Start, and End columns in the Calendar List view
Lite, LookOut, and WorldClient themes - Added <ROOT> as top most option when creating or editing a folder.

IPv6 Support (MDaemon PRO only)
MDaemon now supports
92
. MDaemon will detect the level of IPv6 capability that your OS supports and dual-stack where possible; otherwise, MDaemon will monitor both networks independently. Outbound SMTP, POP, and IMAP connections will prefer IPv6 over IPv4 whenever possible.
When MDaemon connects to an IPv6 host it must use an IPv6 local address of its own.
Therefore the Domain Manager's
154
screen now contains a separate edit control where you can specify an IPv6 address for the domain to use. If this IPv6 address is missing MDaemon will try to automatically detect a suitable address for use.
Buttons to manually detect and designate IP addresses were also added to the same screen.
Finally, $PRIMARYIP6$ and $DOMAINIP6$ macros can be used to retrieve IPv6 addresses. These macros can be used anywhere that the $PRIMARYIP$ and
$DOMAINIP$ macros can be used.
Improved UI
MDaemon 15.0 includes a number of improvements to the user interface:
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

ACL.
Mailing List Manager
Mailing lists are now administered from the new
212
, accessed under the Setup menu. Consequently, the Lists menu was removed from the menu bar and several list editor screens were reorganized and redesigned. Further, several listrelated global options that were located on the Preferences dialog and the Mailing List
Editor were moved to a new
215
screen on the Mailing List Manager.
Gateway Manager
Domain gateways are now administered from the new
193
, accessed under the Setup menu. Consequently, the Gateways menu was removed from the menu bar and several Gateway Editor screens were reorganized and redesigned. Further, the
Gateway Editor's Account screen was deprecated and removed.
Other UI Changes
Below is a list of additional changes to the MDaemon 15.0 interface. For an exhaustive list of UI changes, see the 15.0 Release Notes.
The
513
was moved from Security Settings to Sender Authentication.
Mail Scheduling Options was renamed to
311
.
All screens named "Options" throughout the interface were renamed to
"Settings".
There is a new
93
screen located under Server Settings. Several options related to inbound and outbound socket binding were moved there from the
Preferences dialog. It also contains separate edit controls for IPv4 and IPv6 addresses.
The WorldClient-related dynamic screening options were moved to a new
272
page under WorldClient (web mail).
The
598
contains new options for displaying only accounts that are forwarding mail, are over-quota, or have autoresponders configured.
Improved Hijack Detection (MDaemon PRO only)
559
was expanded, allowing you to define different message and timing thresholds based on whether the connecting IP address is a reserved IP, a local IP, or some other IP.
WorldClient Changes
End-to-end Email and Attachment Encryption
The WorldClient theme is now equipped with support for end-to-end email and
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
33
attachment encryption through Virtru. To enable this feature, the WorldClient user must switch to the WorldClient theme, go the the Options » Compose page, and click
Enable Virtru. This causes a button to appear on the Compose page that the user can click to encrypt his or her email before sending. This is an easy-to-use feature that doesn't require the user to remember or save any special passwords or keys. Recipients who use a Virtru-enabled client, such as the WorldClient theme or one of Virtru's other client plugins, can open and read the encrypted messages normally, without any additional steps. Recipients without a Virtru-enabled client will see a link to view the message in a special browser-based reader.
If you wish to prevent your users from being able to use Virtru encryption within
WorldClient, open the Domains.ini file in the MDaemon/WorldClient folder and add
VirtruDisabled=Yes
to the [Default:Settings] section, or add it to a
[<Domain>:Settings]
section if you only wish to disable it for a specific domain.
For more information, see: Email Encryption .
Contacts Improvements
LookOut Theme
Improved distribution list editor.
Added the Categories column to the Contact List
Added more column-display options under Options » Columns » Contacts.
Under Options » Personalize » Contacts, you can now adjust the length of time you must hover the pointer over a contact in the Contact List before the
Contact Info Preview will appear. You can also disable the Contact Info Preview.
Other Themes
Added the ability to print individual contacts in Lite, LookOut, and WorldClient themes.
Other WorldClient Changes
RPost is now disabled and the option is not visible to users by default. If you wish to make the RPost option available to all of your WorldClient users, open the Domains.ini file in the MDaemon/WorldClient folder, locate the
[Default:Settings]
section, and add RPostEnabled=Yes to that section. If instead you wish to make it available to a specific domain's users, add the key to that relevant [<domain>:Settings] section (e.g. [example.com:Settings]).
When editing a Note or Task in the WorldClient theme, you can now click a button on the editor's toolbar to open the item in a new window.

1.4 Upgrading to MDaemon 17.0.1
Below is a list of special considerations and notes that you may need to be aware of when upgrading to MDaemon version 17.0.1 from a previous version.
WorldClient Instant Messenger (WCIM) now uses the XMPP protocol for instant messaging, which is not compatible with the old chat protocol. Users who do not update to the new version will not be able to instant message with users who have updated. Address book synchronization with Outlook has been removed from WCIM.
The option "Enable APOP & CRAM-MD5" found at
85 has changed to disabled by default for security and technical reasons. Using TLS is the preferred way to avoid transmission of passwords in the clear.
The "Global AUTH Password" setting at
Security » Sender Authentication » SMTP
515
has been deprecated and removed.
All settings related to ADSP found at
Security » Sender Authentication » DKIM
520
and a single option related to the use of the RS= tag found at
Security » Sender Authentication » DKIM Settings
525
have been deprecated and removed.
In-browser WorldClient Instant Messenger (WCIM) has been removed from the
LookOut and WorldClient themes due to incompatibility with the new XMPP WCIM server.
The new
724
to "Store mailbox passwords using non-reversible encryption" is disabled by default for existing installs, to avoid breaking anything for anyone who depends on incompatible features. However, for security reasons we recommend enabling it if you can.
Version 16.5.0
This version of MDaemon is not compatible with previous versions of
Enterprise Server (BES) for MDaemon
378
. BES will be disabled when MDaemon is installed. To continue running BES, update to BES for MDaemon version 2.0.3.
When MX record lookups during message delivery get a DNS server failure result, the message will be left in the queue for attempted delivery during the next processing cycle. This change is to conform with RFC guidelines. Previously,
MDaemon would attempt direct delivery and, failing that, immediately bounce the message in some configurations.
For new installations, the default
92
setting to use IPv6 with outbound hosts has changed to disabled/off.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
35
The
139
option to "log...based on the day of the week" (i.e.,
Monday.log, Tuesday.log, etc) was deprecated and removed. As a result, the option to overwrite log files was no longer necessary and also removed. When upgrading to MDaemon 16.5.0 or later, those set to use the old option are switched to the "log...based on the date" option (i.e., MDaemon-2016-02-22-
X.log, etc). Further, there is a new option to let you set the number of .OLD
backups that are created once the max log file size is reached (previously only one was possible). Finally, hyphens were added to the file names to make the dates easier to read.
515
has a new option to require all incoming messages from local IPs to use authentication or otherwise be rejected.
512
are exempt. This setting is enabled by default for new installations. When upgrading, however, it is disabled to avoid delivery problems from clients or other services that don't authenticate and aren't currently listed as a trusted IP. Please enable this option if you can as it is a good security practice.
Another new
515
option requires the credentials used for
AUTH to match those of the address in the FROM header. This prevents cases where a sender authenticates as one user while claiming within the message to be another user. This option is enabled by default and handles aliases as if they were the real email account. Further, to support gateway mail storage and forwarding, there is a corresponding option located on the
197
screen that will "Exempt gateway mail from AUTH credential
matching requirements" by default.
A new
197
option to "Perform verification lookups on
senders as well as recipients" makes it possible for you to use gateway address verification to verify senders, whereas previously only recipients could be verified. This option is enabled by default, which means that it is now possible for messages sent from addresses that cannot be verified to be refused in some cases where they might have been accepted before. If this is not to your liking then disable the new option.
The
170
and
103
options have been changed.
Previously, the Last Modified Date of each message file was used when determining which messages to delete based on their age. Now the Date: header within the message itself is used. If there is no Date: header or it doesn't comply with standards, then the Last Modified Date file property is used.
On the
145
dialog, there is a new option that governs the maximum number of days that the Antivirus update log (i.e. avupdate.log) will keep data. At midnight each night, and also whenever MDaemon starts after upgrading, older data will be deleted from the file. By default the last 30 days of data are kept.
Options were added to
202
and
700
to allow you to choose whether or not to chase referrals in LDAP connections. Sometimes an LDAP server doesn't have a requested object but may have a cross-reference to its location, to which it can refer the client. If you want MDaemon to chase (i.e. follow) these referrals, you can enable the option on the associated screen. Previously MDaemon chased referrals by default and there was no option to disable it. Now it is disabled by default.
The default settings for the
465
options below were changed for new

36 MDaemon Messaging Server 17.0
installations. They are not changed when upgrading, but it is recommended that you compare them to your current installation, and that you review the new
MDPGP options, to see if the new settings would work better for you:
"Enable MDPGP" (enabled by default)
"Authorize all local MDaemon users for all services" (enabled by default)
"Sign mail automatically if sender's private-key is known" (disabled by default)
"Encrypt/Sign mail sent to self" (enabled by default)
"Email public-keys when requests are made (--pgpk command)" (enabled by default)
"Email details of encryption failures to sender (--pgpe command)" (enabled by default)
"Expires in 0 days" (changed to 365 by default)
Even though most of these settings are now enabled by default (including the entire MDPGP service itself) no encryption/decryption related actions can be taken until keys are known and have been added to the key-ring. However, with this version of MDaemon there are now more ways to get that done automatically.
Version 16.0.0
729
queries now include the email address (sender) making the request.
This allows personal blacklists to be checked. If the sender is on the Minger recipient's personal blacklist then a result of "user unknown" will be returned to the Minger client. This change is backward compatible with older Minger servers.
As a result of this change the LDAPCache.dat file format had to be changed.
Your old LDAPCache.dat file has been renamed LDAPCache.dat.old.
The
101
feature was redesigned, as it was causing slow performance. You can no longer archive specifically to "public folders." Instead, you can archive messages to a specific mail folder and then use the Access
Control List to share that folder as needed. The default location for this folder is
C:\MDaemon\Archives\Email\
, but you can set it to any folder you choose.
You can choose to archive inbound messages that are to your local users, outbound messages from your local users, or both. Mailing list messages, messages being relayed, and those with a virus will not be archived. Inbound and outbound messages will be stored in \In\ and \Out\ subfolders, respectively.
They can be further subdivided by using the ...archive based on recipient
address and ...archive based on sender address options. Also, separate archives can be maintained for each domain by using the Provide separate archives for
each MDaemon domain option.
Archived messages are saved in the final state in which they appear in the local user's mail folder, or in the "ready to be delivered" state for outbound messages.
This means that if you, for example, have the content filter make some change to a message, such as adding a header to it, then the archived message will contain that change.
To browse the archive folder use one of your mail accounts (or create a new
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Messaging Server 17.0
37
one) and point its
604
to the same folder used for the archive. If multiple people need access to the archive then log in to the archive account and
629
the desired folder using its
253
.
Note: The old "Mail Archive" public folder is no longer updated. It was left in place, however, so that you can decide what to do with it. For example, move it or copy it somewhere else and then delete the original. In any case, you should remove it from MDaemon's Public Folders directory, as that can greatly improve the performance of the server for all users. The installation and update process does not do this for you automatically because that would cause the update process to take too long, and it could lead to confusion about the status and location of the archive.
465
: The option to share encryption keys across one or more aliases has been removed. Aliases should have their own set of keys so that various identities are safely kept separate. Although the following is not recommended, if you have special circumstances where you need to preserve previous behavior, you can add "Aliases=Yes" (without the quotes) to the [MDPGP] section of
\App\Plugins.dat
and restart MDaemon.
MDaemon no longer leaves Everyone@, MasterEveryone@, and DomainAdmins@ mailing list .GRP files in the APP folder when the options to use those lists are disabled. Leaving those files in the APP folder caused problems because the API assumed the lists were valid if the files existed. If you do not want these files updated or deleted then you can change their file attribute in Windows to Readonly (although this is not recommended). A better approach in such cases would be to create your own lists which can use the same "Send to everyone" macros that these system maintained lists can.
MDaemon was not honoring the mailing list setting that hides the mailing list from the domain's public contacts folder. This has been fixed. When this version of
MDaemon starts for the first time, any errors in the contact folders related to mailing lists will be corrected. If a contact is found when it should not be, the contact is removed and any missing mailing list contacts are created. This will trigger a re-sync of the contact folder for all devices that are linked to it.
A fix to a long standing content filter parsing bug could potentially (rarely) lead to the following issue: In the past, content filter rules which compare the value of a message header would fail to work if the test string being looked for started with a space character. For example, testing whether a header contained the string ' test ' (note the spaces) would sometimes fail. This problem has been fixed but it could mean that rules which previously did not match, now might.
The "Account can modify the public address book" setting was removed from
Account Editor and Template Manager. Access to any public address book is now managed only through the
253
editor for the specific address book folder in question (including any defaults which will apply to newly created accounts). As a result of these changes the MD_SetCanModifyGAB() function in the API has been deprecated and changed to do no work (but left in place for backward compatibility). Also, the CanModifyGAB member of
MD_UserInfo
structure is now read-only. Any changes you make to this member will not be saved. Changes to ACLs are strictly a function of the ACL editor from here forward.
MDaemon's list engine no longer uses the message-id value of the original list
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
38 MDaemon Messaging Server 17.0
message. Each list message will get the same, single, newly generated messageid. The mailing list engine makes many changes to the original list message. Thus it must take ownership and issue a new message-id. However, the old option to
Replace Message-ID with unique value for each member
237
still works but has been disabled by default for new lists and should not be used unless special circumstances require.
Experimentation has revealed several host screen values that are effective in blocking unwanted connections. These have been added as defaults to
HostScreen.dat
for new MDaemon installations. If you are upgrading MDaemon, you can rename or remove HostScreen.dat and restart MDaemon to get this new version.
The default "low disk space value" (the value below which MDaemon starts warning you about it) was changed from 100MB to 1000MB. Likewise, the "autoshutoff value" (the value below which MDaemon will disable mail services due to critically low disk space) was changed from 10MB to 100MB. Please check and change the values on the
415
screen if those values present a problem for you.
Version 15.5.0
The daily quota report now includes a column showing the last date and time the account was accessed (via IMAP, POP, WorldClient, etc). This required a change to the QuotaReport.dat template file. Your old file was saved as
QuotaReport.dat.old
in case you have customized it. If so, you may want to similarly customize the new template file.
The default setting for Use colors in UI logs was changed from disabled to enabled. If you don't wish to use
150
you can change the setting at:
410
.
Version 15.0.0
Account
559
is now enabled by default.
555
has changed. The "Watch accounts" checkbox was redundant and therefore removed. The options to freeze accounts and email the postmaster were made into a separate checkboxes, and you can now designate the sources that will trigger the email: SMTP, IMAP, or POP. As in previous versions, this email is not sent when the account in question is already frozen.
Further, the Dynamic Screening settings were reverted to installation defaults, therefore you should check them if you prefer a non-default configuration.
Finally, the WorldClient-related options were moved to their own
272
page under WorldClient (web mail).

2 MDaemon Private Cloud 5.0
Introduction
Alt-N Technologies' MDaemon Messaging Server is a standards-based SMTP/POP3/IMAP mail server that supports Windows 7/Vista/XP/2008/2003 systems and offers a full range of mail server functionality. MDaemon is designed to manage the email needs of any number of individual users and comes complete with a powerful set of integrated tools for managing mail accounts and message formats. MDaemon offers a scalable
SMTP, POP3, and IMAP4 mail server complete with LDAP and Active Directory support, an integrated browser-based email client, content filtering, spam filters, extensive security features, and more.
MDaemon Lite and Pro
MDaemon Messaging Server is generally available in two versions: MDaemon Lite and
MDaemon Pro. With the powerful features of MDaemon Lite, you can host your network's email with MDaemon's full-fledged SMTP server, or you can collect your entire domain's email from a single ISP provided POP3 mailbox via the included
DomainPOP feature. You can also host multiple Mailing Lists, allow your users to access their email via the included WorldClient webmail component, and utilize a number of other features. MDaemon Pro is equipped with everything in Lite, plus its support for
IMAP4, multiple domains, Domain Sharing, Gateways, expanded Mailing Lists, and
BlackBerry smartphone integration make it ideal for larger organizations with greater needs. MDaemon Pro also adds group calendar and scheduling, an instant messaging system, multiple language support for WorldClient, automatic domain gateway creation, and more. For a detailed comparison chart outlining the features included in each version, visit: www.altn.com
.
MDaemon Private Cloud
MDaemon Private Cloud (MDPC) is a special edition of the MDaemon Messaging Server that was developed specifically for resellers and IT Service providers who wish to use
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
43
MDaemon software to provide hosted email services to their customers. Unlike
MDaemon Lite and Pro, which are sold for on-premise use, MDPC was built on a new licensing and code foundation specifically designed for use in a hosted environment.
MDaemon Private Cloud includes all MDaemon Pro features and the following additional features:
New licensing and billing (per-user/per-month)
Outlook support
Improved multi-domain control
Per-domain branding (white label)
Per-domain reporting
Non-billable user test accounts (counts will not be included in total billing counts)
Commtouch Outbreak Protection and Antivirus and the ClamAV antivirus engine
(optional with additional cost)
ActiveSync for MDaemon (optional with additional cost)
MDaemon Features
MDaemon is equipped with many features besides SMTP, POP3, and IMAP4 email processing. The following is a list of just some of those features.
MDaemon Pro includes a fully integrated BlackBerry® Enterprise Server, which makes it possible for your users to synchronize their MDaemon email, calendar, contacts, and other PIM data with a
15
.
Complete support for virus scanning and protection is available as an add-on to your MDaemon Private Cloud license. This provides access to Commtouch's realtime
456
and
451
technology and the
462 antivirus engine. Messages can then be scanned for viruses and cleaned or deleted automatically before ever reaching the intended recipients. Further, you can configure MDaemon to send a message to the administrator, sender, and recipient of the infected message notifying them of the virus.
MDaemon features a complete suite of Mailing List or email group management functions allowing for the formation of an unlimited number of distinct distribution lists that can contain local and/or remote members. Lists can be set to allow or refuse subscription requests, be public or private, post replies to either the list or the originator of the message, be sent in digest format, and be configured using numerous other features.
An integrated component of MDaemon is
258
. This exciting product makes it possible for your users to access their email using their favorite web browser rather than from a workstation dependent email client. This tool is perfect for mobile staff and users who do not have a dedicated machine from which to access their email.
WorldClient is equipped with a complete suite of email client features. You can: send and receive email, spell check messages, manage your email in multiple personal folders, display the interface in any of 18 languages, schedule meetings and appointments and share calendars and tasks with other users, manage your
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
44 MDaemon Messaging Server 17.0
MDaemon account settings (when used in conjunction with
286
), manage contacts, and more. WorldClient is also equipped with
259
, a small utility that can be downloaded and installed on a user's local computer. This provides easy access to your email and folders and checks for new messages without having to open your web browser. It also includes a complete Instant Messaging system that can be used to quickly "chat" with other MDaemon/WorldClient users.
MDaemon is equipped with many features designed to help you make your email system secure. The Spam Filter and DNS Black Lists features will help you put an end to most "spam" email messages that "spammers" try to route through or to your domain. IP and Host Screening and the Address Blacklist provide the capability to screen and prevent certain addresses and domains from connecting to or sending mail through your system. They also make it possible to connect to specific IP addresses while screening all others.
Equipped with support for Lightweight Directory Access Protocol (LDAP),
MDaemon can keep your LDAP server up to date on all of its user accounts. This makes it possible for you to keep an LDAP address book up to date so that users with email clients that support LDAP can access it. You can also choose to use
Active Directory or your LDAP server as the MDaemon account database instead of an ODBC compliant database or the local USERLIST.DAT system. Thus, you can configure multiple MDaemon's at different locations to share the same account database.
MDaemon's extensive parsing features make it possible to provide email for an entire LAN with as little as a single dial-up ISP POP3 mailbox. This makes it possible to provide email to an entire network for a fraction of the normally associated cost.
MDaemon can be configured to keep your Windows Address Book or Microsoft
Outlook Contact Store up to date with your user information. This provides another means of making a global address book available to your users.
Address Aliases provides the ability to route email messages addressed to
"fictitious" mailboxes to a valid account or mailing list. This makes it possible for individual accounts and lists to have multiple email addresses at one or more domains.
The Domain Gateways feature provides the option of setting up separate domains for various departments or groups that may be local to your network or located somewhere else on the Internet. Using this feature, all mail addressed to a domain for which MDaemon is acting as a gateway will be placed in that domain's mailbox by MDaemon. It can then be collected by that domain's
MDaemon server or email client and distributed to the domain's users. This feature can also be used to enable MDaemon to act as a backup mail server for other domains.
Accounts can be controlled remotely by users by using specially formatted email messages. This allows greater administrative flexibility, and empowers users by turning day-to-day simple account maintenance tasks, such as changing passwords, over to them.
Integrated web-based remote administration. MDaemon's
286
component is integrated with MDaemon and WorldClient and enables your users to review and edit their account settings via their web-browser. You can
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
45
designate which settings that your users may edit, and assign access permissions on a per account basis. Remote Administration can also be used by the Administrator (and whomever else you wish to allow) to review or edit any of
MDaemon's settings and any other files that you wish to make available to the
Remote Administration system for reviewing.
With File Catalogs, the email administrator can create password protected groups of files which users can have encoded and automatically sent to them through the use of specially formatted email messages.
An internal message transport system known as RAW mail provides a simple method for placing messages into the mail stream and greatly simplifies custom mail software development. Using RAW, a complete mail system can be devised using a simple text editor and a couple of batch files.
A highly versatile Content Filtering system makes it possible for you to customize server behavior based on the content of incoming and outgoing email messages.
You can insert and delete message headers, add footers to messages, remove attachments, route copies to other users, cause an instant message to be sent to someone, run other programs, and more.
System Requirements

XMPP
306
WorldClient Instant Messenger
259
(WCIM)
WCIM now uses the XMPP protocol for instant messaging instead of WorldClient's proprietary protocol. This allows the WCIM desktop client to communicate not only with other WCIM clients, but any third-party XMPP clients (including mobile clients) connected to your MDaemon's XMPP server. Additionally, WCIM now has two types of connections: "WCMailCheck" and "WCIMXMPP." WCMailCheck connects to WorldClient for new mail notifications and message counts. WCIMXMPP connects to the XMPP server for instant messaging. Consequently, WCIM users will now have an entry for each type of connection listed on the Connections screen of the client (e.g.
"Example.com Mail" and "Example.com WCIM"). When updating to version 17, WCIM will automatically create a WCIMXMPP connection to go with your already existing
WCMailCheck connection, and it will migrate your IM contacts from the old system to
XMPP. The look and feel of the new WCIM client is essential the same, but there are some differences, such as how contacts and group chats are managed. See the WCIM client's Help system for more info about what has changed.
WorldClient Dropbox Integration
279
WorldClient is new equipped with direct support for Dropbox, which allows your users to save file attachments to their Dropbox accounts, and to insert direct links to Dropbox files in outgoing messages. To provide this feature to your WorldClient users, you must
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
47
set up your WorldClient as a Dropbox app on the Dropbox Platform . This is a simple process, requiring you only to sign in to a Dropbox account, create a unique name for an app with Full Dropbox access, specify the Redirect URI to WorldClient, and change one default setting. Then, you will copy and paste the Dropbox App Key and App
Secret from there to the options on Dropbox screen in MDaemon. After that your users will be able to link their Dropbox accounts to WorldClient when they next sign in to
WorldClient. For step-by-step instructions on how to create your Dropbox app and link it to WorldClient, see:
Creating and Linking Your Dropbox App
281
.
When you create your Dropbox app it will initially have "Development" status. This allows up to 500 of your WorldClient users to link their Dropbox accounts to the app.
According to Dropbox, however, "once your app links 50 Dropbox users, you will have two weeks to apply for and receive Production status approval before your app's ability to link additional Dropbox users will be frozen, regardless of how many users between 0 and 500 your app has linked." This means that until you receive production approval,
Dropbox integration will continue to work but no additional users will be able to link their accounts. Obtaining production approval is a straightforward process to ensure that your app complies with Dropbox's guidelines and terms of service. For more information, see the Production Approval section of the Dropbox Platform developer guide .
Once your WorldClient app is created and configured properly, each WorldClient user will be given the option to connect their account to their Dropbox account when they sign in to WorldClient. The user is required to log in to Dropbox and grant permission for the app to access the Dropbox account. Then the user will be redirected back to
WorldClient using a URI that was passed to Dropbox during the authentication process.
For security that URI must match one of the Redirect URIs you specified on your app's info page at Dropbox.com. Finally, WorldClient and Dropbox will exchange an access code and access token, which will allow WorldClient to connect to the user's Dropbox account so that the user can save attachments there. The exchanged access token expires every seven days, meaning that periodically the user must reauthorize the account to use Dropbox. Users can also manually disconnect their account from
Dropbox, or reauthorize it when necessary, from the Cloud Apps options screen within
WorldClient.
MDaemon Health Check
MDaemon is now equipped with a new troubleshooting utility called MDaemon Health
Check, located at: MDaemon\App\MDHealthCheck.exe. It can be launched from the
MDaemon UI using a new toolbar button or the new menu item under the Help menu.
Click Analyze on the MDaemon Health Check interface to have it scan MDaemon's security-related settings (AV, SPAM, SSL, etc.) to find settings that are not recommended. All non-recommended settings are then displayed on the screen. Each entry contains the name of the setting, its current value, the recommended value, and the location in MDaemon where that setting can be found. You can then select any entries you wish to change to the recommended value and click Set to Recommended to have MDaemon change them for you. Finally, MDaemon Health Check also creates a log file of the analysis and places it in MDaemon\Logs. The log includes the current value of all the analyzed settings and any warnings or errors found. There is an Open
Log button for displaying the last log generated.
Integration with Let's Encrypt via PowerShell script
To support
563
for
565
,
568
, and
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
48 MDaemon Messaging Server 17.0
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

Option to store mailbox passwords using non-reversible encryption
There is a new
724
to store mailbox passwords using non-reversible encryption. This protects the passwords from being decrypted by MDaemon, the administrator, or a possible attacker. When enabled, MDaemon uses the bcrypt password hashing function, which allows for longer passwords (up to 72 characters), and for passwords to be preserved yet not revealed when exporting and importing accounts. Some features, however, are not compatible with this option, such as weak password detection and APOP & CRAM-MD5 authentication, because they depend on
MDaemon being able to decrypt passwords. Non-reversible passwords is disabled by default.
ActiveSync Client Approval
There is a new ActiveSync setting that you can use to require that "New clients must be authorized by an administrator prior to synchronizing" with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the
339
and
642 client settings screens. The global option is Off by default and the account option is set to "Inherit."
ActiveSync Notifications
Two types of administrative notifications have been added to ActiveSync: Sync
Rollback Notifications and Corrupt Message Notifications.
Sync Rollback Notifications
The ActiveSync Service can now notify the administrators if a client is repeatedly/ frequently sending expired Sync Keys in Sync operations.
These merely inform the admin that the server issued a rollback for a given collection because a client made a sync request with the most recently expired
Sync Key. The subject states "ActiveSync Client Using expired Sync Key". This could occur because of a network issue or something about the content previously sent to the client in that collection. In some cases, the item ID will be there, it merely depends upon whether or not the previous sync on that collection sent any items.
Rollback warnings do not mean the client is out of Sync, it means that the client has the potential to go out of Sync and our internal system detected it. Rollback warnings are issued for a collection no more than once per 24 hour period.
[System] SendRollbackNotifications=[0|1|Yes|No|True|False]
[System] RollbackNotificationThreshhold=[1-254] : The number of rollbacks that must occur on a given collection prior to a notification being sent to the admin. We recommend a value of at least 5 here, since Network hiccups play a part in this.
[System] RollbackNotificationCCUser=[0|1|Yes|No|True|False] : Whether or not to CC the user whose client sent that expired Sync Key.

50 MDaemon Messaging Server 17.0
ActiveSync Corrupt Message Notifications
The ActiveSync Service can now notify the administrators if a particular message cannot be processed. These are sent in real time to inform the admin of a mail item that could not be parsed and that further action on this item is not possible. The subject states "Corrupt message notification". These items, in previous versions, could lead to a crash. In most cases, the content of the msg file will not be MIME data. If it is MIME data, it is likely corrupt. You can choose to CC the affected user of these notifications with the CMNCCUser key so that they are aware that an email has arrived in their mailbox that is un-readable. The appropriate action for these is to move the designated msg file from the user's mailbox and analyze it to determine both why it is not able to be parsed and how it came to exist in the state that it is in.
[System] CMNCCUser==[0|1|Yes|No|True|False]

New in MDaemon 16.5
MDPGP Improvements
465
Key Server Support
WorldClient
WorldClient can now act as a basic public-key server. Enable the new MDPGP option to
"Send public-keys over HTTP (WorldClient)" and WorldClient then will honor requests for your users' public-keys. The format of the URL to make the request looks like this:
"http://<WorldClient-URL>/WorldClient.dll?View=MDPGP&k=<Key-ID>". Where
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
51
<WorldClient-URL>
is the path to your WorldClient server (for example, "http:// wc.example.com
") and <Key-ID> is the sixteen character key-id of the key you want
(for example, "0A1B3C4D5E6F7G8H"). The key-id is constructed from the last 8 bytes of the key fingerprint - 16 characters in total.
DNS (PKA1)
Enable the new MDPGP option to "Collect public-keys from DNS (pka1) and cache for
[xx] hours" if you want MDPGP to query for message recipient public-keys over DNS using PKA1. This is useful because it automates the process of obtaining some recipients' public keys, preventing you or your users from having to obtain and import them manually in order to send encrypted messages. When PKA1 queries are made, any key URI found is immediately collected, validated, and added to the key-ring. Keys successfully collected and imported to the key-ring using this method will automatically expire after the number of hours specified in this option or according to the TTL value of the PKA1 record that referred them, whichever value is greater.
Key Handling
Tracking Keys
MDPGP now always tracks keys by their primary key-ids rather than sometimes by the key-id and other times the sub-key-id. Consequently, the MDPGP dialog's list of keys was cleaned up to remove two unnecessary columns. Further, MDPGP now more strictly controls the contents of its "exports" folder. As a result you will always find exported copies of local user keys there. Even though the private keys are encrypted, for extra security you should use OS tools to protect this folder (and indeed the entire PEM folder structure) from unauthorized access.
Preferred Keys
Previously, when multiple different keys for the same email address were found in the key-ring, MDPGP would encrypt messages using the first one that it found. Now you can right-click on any key and set it as preferred, so that MDPGP will use that key when multiple keys are found. If no preferred key is declared, MDPGP will use the first one found. When decrypting a message MDaemon will try each one.
Disabled Keys
Disabled and deleted keys are now tracked in a new file called oldkeys.txt.
Previously, disabled keys were tracked in the plugins.dat file.
MDPGP Signature Verification
MDPGP can now verify embedded signatures found within messages that are not encrypted. Previously it was not able verify signatures unless the message was both signed and encrypted. When viewing a message with a verified signature in WorldClient, a new icon is displayed to indicate it was verified. Signature verification is enabled by default for all non-local users, or you can specify exactly which email addresses can and cannot use the service (see: "Configure exactly who can and can not use MDPGP
services" on the
465
).

52 MDaemon Messaging Server 17.0
XMPP Instant Messaging Server
306
MDaemon is now equipped with an Extensible Messaging and Presence Protocol (XMPP) server, sometimes called a Jabber server. This allows your users to send and receive instant messages using third-party XMPP clients , such as Pidgin , Gajim , Swift and many others. Clients are available for most operating systems and mobile device platforms.
MDaemon's XMPP instant messaging system is completely independent of MDaemon's
WorldClient Instant Messenger chat system; the two systems cannot communicate with each other and do not share buddy lists.
The XMPP server is installed as a Windows service, and the default server ports are
5222 (SSL via STARTTLS) and 5223 (dedicated SSL). The XMPP server will use
MDaemon's SSL configuration if it is enabled in MDaemon. Also, some XMPP clients use
DNS SRV records for auto-discover of host names. Please refer to http://wiki.xmpp.org/ web/SRV_Records for more information.
Users sign-in through their chosen XMPP client using their email address and password.
Some clients, however, require the email address to be split into separate components for signing in. For example, instead of "[email protected]," some clients require you to use "frank" as the Login/Username and "example.com" as the Domain.
For multi-user/group chat service, clients typically display this as "rooms" or
"conferences." When you want to start a group chat session, create a room/ conference (giving it a name) and then invite the other users to that room. Most clients don't require you to enter a server location for the conference; you only need to enter a name for it. When you are required to do so, however, use
"conference.<your domain>" as the location (e.g. conference.example.com). A few clients require you to enter the name and location together in the form:
"room@conference.<your domain>" (e.g. [email protected]).
Some clients (such as Pidgin ), support the user search service, allowing you to search the server for users by name or email address, which makes adding contacts much easier. Usually you will not have to provide a search location, but if asked to do so, use
"search.<your domain>" (e.g. search.example.com). When searching, the % symbol can be used as a wildcard. Therefore you could use "%@example.com" in the email address field to display a list of all users with an email address ending in
"@example.com."
Centralized Management of OC Client Settings
321
Use the OC Client Settings dialog to centrally manage the client settings of your
Outlook Connector users. Configure each screen with your desired client settings and
MDaemon will push those settings to the corresponding client screens as necessary, each time an Outlook Connector user connects to the server. The OC Client Settings are only sent to clients when one of the settings has changed since the last time the client connected and received them. If you enable the provided option to "Allow OC
users to override pushed settings," users can override any pushed settings on their individual clients. If that option is disabled, then all of the client screens are locked;
Outlook Connector users can make no changes.
To allow for certain settings that must be different for each user or domain, OC Client
Settings supports macros such as $USERNAME$, $EMAIL$, and $DOMAIN$. These macros will be converted to data specific to the user or domain when pushing settings to a
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
client. Take care not to place any static values in any fields that should use a macro, such as putting something like "Frank Thomas" in the Your Name field. To do so would cause every Outlook Connector user who connects to MDaemon, to have his or her name set to "Frank Thomas." For your convenience there is a Macro Reference button on the
323
screen, which displays a simple list of the supported macros.
For those using MDaemon Private Cloud (MDPC), there is another OC Client Settings dialog on the
152
, for controlling the Outlook Connector client settings on a per domain basis.
This feature is disabled by default, and works only for those using Outlook Connector client version 4.0.0 or higher.
"From:" Header Protection/Modification
559
This new security feature modifies the "From:" header of incoming messages to cause the name-only portion of the header to contain both the name and email address. This is done to combat a common tactic used in spam and attacks where the message is made to appear to be coming from someone else. When displaying a list of messages, email clients commonly display only the sender's name rather than the name and email address. To see the email address, the recipient must first open the message or take some other action, such as right-click the entry, hover over the name, or the like. For this reason attackers commonly construct an email so that a legitimate person or company name appears in the visible portion of the "From:" header while an illegitimate email address is hidden. For example, a message's actual "From:" header might be,
"Honest Bank and Trust" <[email protected]>, but your client might display only "Honest Bank and Trust" as the sender. This feature changes the visible portion of the header to display both parts, with the email address given first. In the above example the sender would now appear as
"[email protected] -- Honest Bank and Trust,"
giving you a clear indication that the message is fraudulent. This option only applies to messages to local users, and it is disabled by default.
Improved IP Screening
550
The IP Screen now contains an Import button that you can use to import IP address data from an APF or .htaccess file. MDaemon's support for these files is currently limited to the following:
"deny from" and "allow from" are supported only IP values are imported (not domain names)
CIDR notation is allowed but partial IP addresses are not.
Each line can contain any number of space-separated or comma-separated IP addresses. For example, "deny from 1.1.1.1 2.2.2.2/16", ""3.3.3.3, 4.4.4.4,
5.5.5.5", and the like.
Lines starting with # are ignored.
Automatic Installation of Product Updates
420
Using the Automatic Updates features you can configure MDaemon to inform the postmaster whenever an update is available for one of your installed products, or you
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
53
54 MDaemon Messaging Server 17.0
can download and install updates automatically. This includes MDaemon, SecurityPlus, and Outlook Connector. Automatically installing updates can be controlled separately for each product, and a server reboot is required each time an update is installed.
Installer files are downloaded when the update is detected, but the installation and reboot occur later at whichever hour you have designated. All installation activity is logged in the MDaemon system log, and the postmaster is informed after an update has occurred. See the
420
dialog for more information.
WorldClient Changes
285
WorldClient supports categories for email in the LookOut and WorldClient themes. Users can add the Categories column to the message list by going to "Options » Columns" and checking "Categories" in the Message List section. To select categories for one or multiple messages, select the messages and right-click one of them. Use the context menu to set the category.
Administrators can create custom categories. There are two files for this purpose: DomainCategories.json and PersonalCategories.json.
Domain Categories are enabled globally by default. To disable them open
MDaemon\WorldClient\Domains.ini
, and in the [Default:Settings] section change the value of "DomainCategoriesEnabled=" from "Yes" to "No".
Users are able to add and edit their own categories by default. If you wish to disable this option, you can do so per user or globally by changing the value of
"CanEditPersonalCategories=" from "Yes" to "No". The user option is located in the [User] section of the User.ini file and the global option is in the
Domains.ini
file under the [Default:UserDefaults] section.
If Domain Categories are enabled, and a user is not allowed to edit personal categories, the user will only see the categories listed in
DomainCategories.json
.
If Domain Categories are disabled, and a user is not allowed to edit personal categories, the user will see the categories listed in PersonalCategories.json.
The file CustomCategoriesTranslations.json is used to support your custom category names in multiple languages. Add any necessary custom category translatations to that file to make it possible for WorldClient to recognize a category saved to an event, note, or task in one language as the equivalent category in another language.
For more detailed information relating to the files mentioned here, see: MDaemon
\WorldClient\CustomCategories.txt
.
285
You can now hide the White List and Black List folders for WorldClient users by default.
To do so, open MDaemon\WorldClient\Domains.ini, and under
[Default:UserDefaults]
change the value of "HideWhiteListFolder=" or
"HideBlackListFolder=" from "No" to "Yes". You can hide or show these folders for specific users by editing those same keys in the User.ini file under the [User] section.

MDaemon Private Cloud 5.0
55
Check for Attachments
In the LookOut and WorldClient themes there is now an option to check a composed message for attachments before sending, when attachments are mentioned in the subject or body of the message. This can help you avoid accidentally sending a message without an attachments when it is supposed to include one.
607
You can now control whether or not accounts are allowed to use or required to use
Two-Factor Authentication (2FA). There are two new options on the
673 template for controlling the default settings for new accounts, and there are corresponding options on the
607
screen for controlling 2FA for individual accounts.
New in MDaemon Private Cloud 4.0

New in MDaemon 16.0
MDaemon Remote Administration (MDRA) UI Update
The user interface for MDRA no longer uses frames and has been updated to use a mobile first responsive design. Browser support is limited to IE10+, the latest Chrome, the latest Firefox, and the latest Safari on Mac and iOS. Android stock browsers have been known to have issues with scrolling, but Chrome on Android devices works well.
This design is based entirely on the size of the window being used. Whether the user is on a phone, tablet, or PC, the appearance is the same for the same window size. The most important change here is the menu. From 1024 pixels width and below, the menu is hidden on the left side of the browser. There are two methods that can be used to display the menu. If a touch device is in use, swiping to the right will show the secondary menu. Whether or not the device is in use, there is also a "menu" button in the top left corner that will display the secondary menu. Tapping or clicking the menu title with the left arrow next to it at the top of the menu will display the primary menu.
The help, about, and sign out menu in the top right corner changes based on the width of the screen as well. From 768 pixels and above, the words Help, About, and Sign Out are displayed. From 481 pixels to 767 pixels, only the icons are displayed. 480 pixels and below displays only a "gear" icon which when clicked or tapped will display a drop down menu with the Help, About, Sign Out options. List views with more than one

column have column on/off buttons that are accessed by clicking or tapping the gray right arrow button on the far right of the toolbar container. The settings pages are no longer designed to be exact copies of the MDaemon GUI, but are instead designed to reposition and resize based on the width/height of the browser.
Spambot Detection
562
(MDaemon PRO only)
A new feature called Spambot Detection tracks the IP addresses that every SMTP MAIL
(return-path) value uses over a given period of time. If the same return-path is used by in an unusual number of IP addresses in a short period of time, this may indicate a spambot network. Although it could still be a legitimate use of the mail system, experimentation has shown that this can be effective in limited cases at detecting a distributed spambot network as long as the same return-path is utilized throughout. If a spambot is detected, the current connection to it is immediately dropped and the return-path value is optionally blacklisted for a length of time you specify. You can also optionally blacklist all the spambot IPs then known for a user-defined period.
CardDAV
301
(MDaemon PRO only)
MDaemon now supports synchronizing contacts via the CardDAV protocol. MDaemon's
CardDAV server allows an authenticated CardDAV client to access the contact information that is stored in MDaemon. Notable CardDAV clients are Apple Contacts
(included with Mac OS X), Apple iOS (iPhone), and Mozilla Thunderbird via the SOGO plugin . For more information on CardDAV and configuring CardDAV clients, see:
301
.
Two Factor Authentication for WorldClient and Remote
Administration
MDaemon now supports Two Factor Authentication (i.e. 2-Step Verification) for users signing into WorldClient or MDaemon's Remote Administration web-interface. Any user who signs into WorldClient via HTTPS can activate Two Factor Authentication for the account on the Options » Security screen. From then on the user must enter a verification code when signing into WorldClient or Remote Administration. The code is obtained at sign-in from an authenticator app installed on the user's mobile device or tablet. This feature is designed for any client that supports Google Authenticator.
ActiveSync Protocol Migration Client
MDaemon now includes an ActiveSync protocol based Migration Client (ASMC.exe). It supports migrating mail, calendars, tasks, notes, and contacts from ActiveSync servers that support protocol version 14.1. Documentation for it can be found in the \MDaemon
\Docs
folder.
XML API for Management Tasks
MDaemon now ships with an XML over http(s) based API. The result of this is that
MDaemon Management clients can be written using any language on any platform that can make http(s):// post requests to the server. In MDaemon Pro, this is only available to authenticated Global Admins, but in MDaemon Private Cloud a subset of the available operations is accessible to authenticated domain admins as well. The API also produces a website with documentation on the API specification. The installation default is to

have it installed at http://servername:RemoteAdminPort/MdMgmtWS/, however, this can be set to any url for the sake of additional security.
The available operations include:

At this time, command line management clients have been written/tested in Javascript,
Powershell, VBScript, C, C++ and Visual Basic. A simple HTML and Javascript test site has been used as a proof of concept for a web based management console that operates within several popular browsers. While not tested yet, it is fully expected that this API should work fine from web servers using PHP, Perl, and other development platforms.

CALDAV (MDaemon PRO only)
301
MDaemon in now equipped with a CalDAV server. CalDAV is an Internet standard for managing and sharing calendars and scheduling information. MDaemon's CalDAV support makes it possible for your accounts to use any client that supports CalDAV to access and manage their personal calendars and tasks. They can also access any
251
or
629
calendars or tasks according to their
253
.
MDPGP Provides OpenPGP Support (MDaemon PRO only)
465
OpenPGP is an industry standard protocol for exchanging encrypted data, and there are a variety of OpenPGP plugins for email clients that make it possible for users to send and receive encrypted messages. MDPGP is MDaemon's integrated OpenPGP component that can provide encryption, decryption, and basic key management services for your users without requiring them to use an email client plugin.
MDPGP encrypts and decrypts emails using a public-key/private-key system. To do this, when you wish to use MDPGP to send a private and secure message to someone,
MDPGP will encrypt that message using a "key" that you previously obtained from that person (i.e. his "public key") and imported into MDPGP. Conversely, if he wishes to send a private message to you, then he must encrypt the message using your public key, which he obtained from you. Giving the sender your public key is absolutely necessary, because without it he can't send you an OpenPGP encrypted message. Your unique public key must be used to encrypt the message because your unique private key is what MDPGP will use to decrypt the message when it arrives.
In order for MDPGP to manage signing, encrypting, and decrypting messages, it maintains two stores of keys (i.e. keyrings)—one for public keys and one for private keys. MDPGP can generate your users' keys automatically as needed, or you can create
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
them manually for specific users. You can also import keys that were created elsewhere. Further, MDaemon can look for public keys attached to authenticated messages from local users, and then import those keys automatically. That way a user can request a public key from someone and then email that key to himself so that
MDPGP will detect it and then import it into the public keyring. Finally, whenever a message arrives for an address that has a key in a keyring, MDPGP will sign, encrypt, or decrypt the message as needed, according to your settings.
You can configure MDPGP's signing and encryption services to operate either automatically or manually. When set to operate automatically, MDPGP will automatically sign and encrypt messages whenever possible. When set to operate manually, MDPGP will only sign or encrypt a message when the sending user inserts a special command into the message's Subject. In any case messages will only be signed or encrypted (or decrypted) when the account has been given permission to use those services.
Do Not Disturb
663
Do Not Disturb is a new
663
that makes it possible for you to schedule a time frame during which an account may not send mail or be accessed by its users. Access during a Do Not Disturb period is not allowed and returns an appropriate error response to IMAP, POP, SMTP, ActiveSync, and WorldClient access requests. MDaemon will still accept incoming mail for accounts in this state, but those accounts may not send mail or be accessed by mail clients.
ActiveSync Redesigned
335
The ActiveSync for MDaemon interface was completely redesigned, and there are a variety of new features and policy options available. You can manage ActiveSync under
335

WorldClient Improvements
Modernized the LookOut theme's icons and colors, and made some adjustments to its layout. There is also a new gray color style, although the default style is blue. The "New" button was moved to where the user's email address was previously located, and the email address is now in the top navigation bar. The
Help and Sign Out options were moved to a drop-down list beneath user's address, like in the WorldClient theme. Finally, the Options icon was moved to

59
60 MDaemon Messaging Server 17.0
the far right in the navigation bar.
WorldClient now supports adding inline images to a user's signature.
Merged Categories and Labels into just Categories. Users can now add, edit, and delete categories from a predefined list based on the old labels and categories.
Each category has a color associated with it. More than one category can be associated with a given color, but only one category with a specific name may exist. There are 26 colors to choose from (including white) which match Outlook category color options. If an event, task, note, or contact already has categories associated with it, but they don't match the predefined categories, their colors will be white until the user adds them to the predefined list of categories. If there is already a label associated with an event, the user can choose to remove the label and add a category, or leave the label. Old labels are not lost on upgrade.
WorldClient and LookOut themes - Desktop notifications are now available. When
LookOut or WorldClient loads, the browser will prompt the user on whether or not to allow desktop notifications. If the user chooses to allow them, then the user will receive notifications of new email messages, new instant messages (in the case that the corresponding chat is not in focus), and any change in status of a chat buddy. Desktop notifications are not supported by Internet Explorer.
WorldClient and LookOut themes - Added ability to view pdf files in the browser
(not supported in IE8). This is available in any document folder and any message that has a pdf file.
There is now a
282
in WorldClient. When this feature is enabled, users who have permission to
607
will be able to enter an alternate email address in WorldClient, which can be sent a link to reset their password if they forget it. To set up this feature, users must enter both the password recovery email address and their current password in WorldClient on the Options » Personalize page. Once set, if the user attempts to log in to
WorldClient with an incorrect password a "forgot password?" link will appear. This link takes them to a page that asks them to confirm their password recovery email address. If entered correctly, an email will be sent with a link to a change password page.
LookOut and WorldClient themes - added buttons and context menu items for users to create a new event, task, or note from the contents of a message.
Lite, LookOut, and WorldClient themes now attempt to detect and use the language currently being used by the browser.
LookOut and WorldClient themes - users can now use the browser's back and forward buttons to navigate in the main window
LookOut and WorldClient themes - Virtru can now be disabled by the admin on a per user basis by adding VirtruDisabled=Yes to the [User] section of the user's WC\User.ini file.
WorldClient theme - added a "Today" button to the calendar view buttons.
LookOut and WorldClient themes - users can now sort by the Description,
Location, Start, and End columns in the Calendar List view

When MDaemon connects to an IPv6 host it must use an IPv6 local address of its own.
Therefore the Domain Manager's
154
screen now contains a separate edit control where you can specify an IPv6 address for the domain to use. If this IPv6 address is missing MDaemon will try to automatically detect a suitable address for use.
Buttons to manually detect and designate IP addresses were also added to the same screen.
Finally, $PRIMARYIP6$ and $DOMAINIP6$ macros can be used to retrieve IPv6 addresses. These macros can be used anywhere that the $PRIMARYIP$ and
$DOMAINIP$ macros can be used.
Improved UI
MDaemon 15.0 includes a number of improvements to the user interface:
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
62 MDaemon Messaging Server 17.0
New Access Control List (ACL) Editor
The
253
was completely redesigned. It now includes more information about the item you are editing and has search features for added new users or groups to the
ACL.
Mailing List Manager
Mailing lists are now administered from the new
212
, accessed under the Setup menu. Consequently, the Lists menu was removed from the menu bar and several list editor screens were reorganized and redesigned. Further, several listrelated global options that were located on the Preferences dialog and the Mailing List
Editor were moved to a new
215
screen on the Mailing List Manager.
Gateway Manager
Domain gateways are now administered from the new
193
, accessed under the Setup menu. Consequently, the Gateways menu was removed from the menu bar and several Gateway Editor screens were reorganized and redesigned. Further, the
Gateway Editor's Account screen was deprecated and removed.
Other UI Changes
Below is a list of additional changes to the MDaemon 15.0 interface. For an exhaustive list of UI changes, see the 15.0 Release Notes.
The
513
was moved from Security Settings to Sender Authentication.
Mail Scheduling Options was renamed to
311
.
All screens named "Options" throughout the interface were renamed to
"Settings".
There is a new
93
screen located under Server Settings. Several options related to inbound and outbound socket binding were moved there from the
Preferences dialog. It also contains separate edit controls for IPv4 and IPv6 addresses.
The WorldClient-related dynamic screening options were moved to a new
272
page under WorldClient (web mail).
The
598
contains new options for displaying only accounts that are forwarding mail, are over-quota, or have autoresponders configured.
Improved Hijack Detection (MDaemon PRO only)
559
was expanded, allowing you to define different message and timing thresholds based on whether the connecting IP address is a reserved IP, a local IP, or some other IP.
WorldClient Changes
End-to-end Email and Attachment Encryption
The WorldClient theme is now equipped with support for end-to-end email and
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
63
attachment encryption through Virtru. To enable this feature, the WorldClient user must switch to the WorldClient theme, go the the Options » Compose page, and click
Enable Virtru. This causes a button to appear on the Compose page that the user can click to encrypt his or her email before sending. This is an easy-to-use feature that doesn't require the user to remember or save any special passwords or keys. Recipients who use a Virtru-enabled client, such as the WorldClient theme or one of Virtru's other client plugins, can open and read the encrypted messages normally, without any additional steps. Recipients without a Virtru-enabled client will see a link to view the message in a special browser-based reader.
If you wish to prevent your users from being able to use Virtru encryption within
WorldClient, open the Domains.ini file in the MDaemon/WorldClient folder and add
VirtruDisabled=Yes
to the [Default:Settings] section, or add it to a
[<Domain>:Settings]
section if you only wish to disable it for a specific domain.
For more information, see: Email Encryption .
Contacts Improvements
LookOut Theme
Improved distribution list editor.
Added the Categories column to the Contact List
Added more column-display options under Options » Columns » Contacts.
Under Options » Personalize » Contacts, you can now adjust the length of time you must hover the pointer over a contact in the Contact List before the
Contact Info Preview will appear. You can also disable the Contact Info Preview.
Other Themes
Added the ability to print individual contacts in Lite, LookOut, and WorldClient themes.
Other WorldClient Changes
RPost is now disabled and the option is not visible to users by default. If you wish to make the RPost option available to all of your WorldClient users, open the Domains.ini file in the MDaemon/WorldClient folder, locate the
[Default:Settings]
section, and add RPostEnabled=Yes to that section. If instead you wish to make it available to a specific domain's users, add the key to that relevant [<domain>:Settings] section (e.g. [example.com:Settings]).
When editing a Note or Task in the WorldClient theme, you can now click a button on the editor's toolbar to open the item in a new window.

2.4 Upgrading to MDaemon Private Cloud 5.0.0
Below is a list of special considerations and notes that you may need to be aware of when upgrading to MDaemon version 17.0.1 from a previous version.
WorldClient Instant Messenger (WCIM) now uses the XMPP protocol for instant messaging, which is not compatible with the old chat protocol. Users who do not update to the new version will not be able to instant message with users who have updated. Address book synchronization with Outlook has been removed from WCIM.
The option "Enable APOP & CRAM-MD5" found at
85 has changed to disabled by default for security and technical reasons. Using TLS is the preferred way to avoid transmission of passwords in the clear.
The "Global AUTH Password" setting at
Security » Sender Authentication » SMTP
515
has been deprecated and removed.
All settings related to ADSP found at
Security » Sender Authentication » DKIM
520
and a single option related to the use of the RS= tag found at
Security » Sender Authentication » DKIM Settings
525
have been deprecated and removed.
In-browser WorldClient Instant Messenger (WCIM) has been removed from the
LookOut and WorldClient themes due to incompatibility with the new XMPP WCIM server.
The new
724
to "Store mailbox passwords using non-reversible encryption" is disabled by default for existing installs, to avoid breaking anything for anyone who depends on incompatible features. However, for security reasons we recommend enabling it if you can.
Version 16.5.0
This version of MDaemon is not compatible with previous versions of
Enterprise Server (BES) for MDaemon
378
. BES will be disabled when MDaemon is installed. To continue running BES, update to BES for MDaemon version 2.0.3.
When MX record lookups during message delivery get a DNS server failure result, the message will be left in the queue for attempted delivery during the next processing cycle. This change is to conform with RFC guidelines. Previously,
MDaemon would attempt direct delivery and, failing that, immediately bounce the message in some configurations.
For new installations, the default
92
setting to use IPv6 with outbound hosts has changed to disabled/off.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
65
The
139
option to "log...based on the day of the week" (i.e.,
Monday.log, Tuesday.log, etc) was deprecated and removed. As a result, the option to overwrite log files was no longer necessary and also removed. When upgrading to MDaemon 16.5.0 or later, those set to use the old option are switched to the "log...based on the date" option (i.e., MDaemon-2016-02-22-
X.log, etc). Further, there is a new option to let you set the number of .OLD
backups that are created once the max log file size is reached (previously only one was possible). Finally, hyphens were added to the file names to make the dates easier to read.
515
has a new option to require all incoming messages from local IPs to use authentication or otherwise be rejected.
512
are exempt. This setting is enabled by default for new installations. When upgrading, however, it is disabled to avoid delivery problems from clients or other services that don't authenticate and aren't currently listed as a trusted IP. Please enable this option if you can as it is a good security practice.
Another new
515
option requires the credentials used for
AUTH to match those of the address in the FROM header. This prevents cases where a sender authenticates as one user while claiming within the message to be another user. This option is enabled by default and handles aliases as if they were the real email account. Further, to support gateway mail storage and forwarding, there is a corresponding option located on the
197
screen that will "Exempt gateway mail from AUTH credential
matching requirements" by default.
A new
197
option to "Perform verification lookups on
senders as well as recipients" makes it possible for you to use gateway address verification to verify senders, whereas previously only recipients could be verified. This option is enabled by default, which means that it is now possible for messages sent from addresses that cannot be verified to be refused in some cases where they might have been accepted before. If this is not to your liking then disable the new option.
The
170
and
103
options have been changed.
Previously, the Last Modified Date of each message file was used when determining which messages to delete based on their age. Now the Date: header within the message itself is used. If there is no Date: header or it doesn't comply with standards, then the Last Modified Date file property is used.
On the
145
dialog, there is a new option that governs the maximum number of days that the Antivirus update log (i.e. avupdate.log) will keep data. At midnight each night, and also whenever MDaemon starts after upgrading, older data will be deleted from the file. By default the last 30 days of data are kept.
Options were added to
202
and
700
to allow you to choose whether or not to chase referrals in LDAP connections. Sometimes an LDAP server doesn't have a requested object but may have a cross-reference to its location, to which it can refer the client. If you want MDaemon to chase (i.e. follow) these referrals, you can enable the option on the associated screen. Previously MDaemon chased referrals by default and there was no option to disable it. Now it is disabled by default.
The default settings for the
465
options below were changed for new
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
66 MDaemon Messaging Server 17.0
installations. They are not changed when upgrading, but it is recommended that you compare them to your current installation, and that you review the new
MDPGP options, to see if the new settings would work better for you:
"Enable MDPGP" (enabled by default)
"Authorize all local MDaemon users for all services" (enabled by default)
"Sign mail automatically if sender's private-key is known" (disabled by default)
"Encrypt/Sign mail sent to self" (enabled by default)
"Email public-keys when requests are made (--pgpk command)" (enabled by default)
"Email details of encryption failures to sender (--pgpe command)" (enabled by default)
"Expires in 0 days" (changed to 365 by default)
Even though most of these settings are now enabled by default (including the entire MDPGP service itself) no encryption/decryption related actions can be taken until keys are known and have been added to the key-ring. However, with this version of MDaemon there are now more ways to get that done automatically.
Version 16.0.0
729
queries now include the email address (sender) making the request.
This allows personal blacklists to be checked. If the sender is on the Minger recipient's personal blacklist then a result of "user unknown" will be returned to the Minger client. This change is backward compatible with older Minger servers.
As a result of this change the LDAPCache.dat file format had to be changed.
Your old LDAPCache.dat file has been renamed LDAPCache.dat.old.
The
101
feature was redesigned, as it was causing slow performance. You can no longer archive specifically to "public folders." Instead, you can archive messages to a specific mail folder and then use the Access
Control List to share that folder as needed. The default location for this folder is
C:\MDaemon\Archives\Email\
, but you can set it to any folder you choose.
You can choose to archive inbound messages that are to your local users, outbound messages from your local users, or both. Mailing list messages, messages being relayed, and those with a virus will not be archived. Inbound and outbound messages will be stored in \In\ and \Out\ subfolders, respectively.
They can be further subdivided by using the ...archive based on recipient
address and ...archive based on sender address options. Also, separate archives can be maintained for each domain by using the Provide separate archives for
each MDaemon domain option.
Archived messages are saved in the final state in which they appear in the local user's mail folder, or in the "ready to be delivered" state for outbound messages.
This means that if you, for example, have the content filter make some change to a message, such as adding a header to it, then the archived message will contain that change.
To browse the archive folder use one of your mail accounts (or create a new
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon Private Cloud 5.0
67
one) and point its
604
to the same folder used for the archive. If multiple people need access to the archive then log in to the archive account and
629
the desired folder using its
253
.
Note: The old "Mail Archive" public folder is no longer updated. It was left in place, however, so that you can decide what to do with it. For example, move it or copy it somewhere else and then delete the original. In any case, you should remove it from MDaemon's Public Folders directory, as that can greatly improve the performance of the server for all users. The installation and update process does not do this for you automatically because that would cause the update process to take too long, and it could lead to confusion about the status and location of the archive.
465
: The option to share encryption keys across one or more aliases has been removed. Aliases should have their own set of keys so that various identities are safely kept separate. Although the following is not recommended, if you have special circumstances where you need to preserve previous behavior, you can add "Aliases=Yes" (without the quotes) to the [MDPGP] section of
\App\Plugins.dat
and restart MDaemon.
MDaemon no longer leaves Everyone@, MasterEveryone@, and DomainAdmins@ mailing list .GRP files in the APP folder when the options to use those lists are disabled. Leaving those files in the APP folder caused problems because the API assumed the lists were valid if the files existed. If you do not want these files updated or deleted then you can change their file attribute in Windows to Readonly (although this is not recommended). A better approach in such cases would be to create your own lists which can use the same "Send to everyone" macros that these system maintained lists can.
MDaemon was not honoring the mailing list setting that hides the mailing list from the domain's public contacts folder. This has been fixed. When this version of
MDaemon starts for the first time, any errors in the contact folders related to mailing lists will be corrected. If a contact is found when it should not be, the contact is removed and any missing mailing list contacts are created. This will trigger a re-sync of the contact folder for all devices that are linked to it.
A fix to a long standing content filter parsing bug could potentially (rarely) lead to the following issue: In the past, content filter rules which compare the value of a message header would fail to work if the test string being looked for started with a space character. For example, testing whether a header contained the string ' test ' (note the spaces) would sometimes fail. This problem has been fixed but it could mean that rules which previously did not match, now might.
The "Account can modify the public address book" setting was removed from
Account Editor and Template Manager. Access to any public address book is now managed only through the
253
editor for the specific address book folder in question (including any defaults which will apply to newly created accounts). As a result of these changes the MD_SetCanModifyGAB() function in the API has been deprecated and changed to do no work (but left in place for backward compatibility). Also, the CanModifyGAB member of
MD_UserInfo
structure is now read-only. Any changes you make to this member will not be saved. Changes to ACLs are strictly a function of the ACL editor from here forward.
MDaemon's list engine no longer uses the message-id value of the original list
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
68 MDaemon Messaging Server 17.0
message. Each list message will get the same, single, newly generated messageid. The mailing list engine makes many changes to the original list message. Thus it must take ownership and issue a new message-id. However, the old option to
Replace Message-ID with unique value for each member
237
still works but has been disabled by default for new lists and should not be used unless special circumstances require.
Experimentation has revealed several host screen values that are effective in blocking unwanted connections. These have been added as defaults to
HostScreen.dat
for new MDaemon installations. If you are upgrading MDaemon, you can rename or remove HostScreen.dat and restart MDaemon to get this new version.
The default "low disk space value" (the value below which MDaemon starts warning you about it) was changed from 100MB to 1000MB. Likewise, the "autoshutoff value" (the value below which MDaemon will disable mail services due to critically low disk space) was changed from 10MB to 100MB. Please check and change the values on the
415
screen if those values present a problem for you.
Version 15.5.0
The daily quota report now includes a column showing the last date and time the account was accessed (via IMAP, POP, WorldClient, etc). This required a change to the QuotaReport.dat template file. Your old file was saved as
QuotaReport.dat.old
in case you have customized it. If so, you may want to similarly customize the new template file.
The default setting for Use colors in UI logs was changed from disabled to enabled. If you don't wish to use
150
you can change the setting at:
410
.
Version 15.0.0
Account
559
is now enabled by default.
555
has changed. The "Watch accounts" checkbox was redundant and therefore removed. The options to freeze accounts and email the postmaster were made into a separate checkboxes, and you can now designate the sources that will trigger the email: SMTP, IMAP, or POP. As in previous versions, this email is not sent when the account in question is already frozen.
Further, the Dynamic Screening settings were reverted to installation defaults, therefore you should check them if you prefer a non-default configuration.
Finally, the WorldClient-related options were moved to their own
272
page under WorldClient (web mail).

3 MDaemon's Main Display
MDaemon's main graphical user interface (GUI) gives you important information regarding MDaemon's resources, statistics, active sessions, and queued mail waiting to be processed. It also contains options for easily activating/deactivating MDaemon's various servers. The GUI's tabbed panes keep you up to date on how the server and its incoming and outgoing connections are performing.
Stats
The Stats pane is the default left pane of MDaemon's main interface. This pane contains four sections: Statistics, Accounts, Queues, and Servers.
The Statistics section contains statistics regarding the number of messages sent and received by MDaemon as well as statistics for POP and IMAP sessions, Spam accepted and refused, viruses, and more. These stats are counted from the time MDaemon starts, and there is a right-click shortcut menu that can be used to clear the counters.
When you click the "reset root node counters" option, all of the counters will be reset, not merely the one you right-click.
Further, there is an option at S etup » Preferences » GUI that can be used to "Preserve root node mail counters across
reboots." Otherwise they will be reset whenever the server is rebooted.
The Accounts section contains entries for MDaemon, Outlook Connector, and
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
MDaemon's Main Display 73
ActiveSync. Each entry lists the number of accounts used and the number of accounts left, depending on your product license.
The Queues section contains an entry for each message queue and the number of messages (if any) that each queue contains. You can right-click on each of the queue entries to open a shortcut menu containing one or more of the following options, depending on which queue you select:
View Queue — this option switches the main pane to the Queues tab and displays the selected queue. A list of all messages the queue contains will be displayed, and you can right-click any message to open a shortcut menu containing numerous options similar to those available in the Queue & Statistics Manager such as Copy, Move, Edit, White list, and so on.
Queue and statistics manager — open the Queue and Statistics Manager to the
Queue Page with the selected queue displayed.
Process Now — this option "re-queues" all messages contained in the queue and attempts to process them normally for delivery. If you attempt to process messages contained in the Holding queue, Bad queue, or the like then the messages may encounter the same errors that put them there in the first place and return them to the same queue.
Freeze/unfreeze queue — temporarily pauses processing for the selected queue, or continues the processing if it is currently paused.
Release — releases messages from the Holding Queue. MDaemon will attempt to deliver the messages regardless of errors encountered — they will not be returned to the Holding Queue even if they encounter the same errors that caused them to be moved there originally.
Re-Queue — This is available for the Holding Queue, and has the same effect as
Process Now above.
Enable/disable queue — activates or deactivates the Holding Queue. When disabled, messages will not be moved to the Holding Queue regardless of errors encountered.
The Servers section contains an entry for each server within MDaemon, and each entry lists the current state of the server: "Active" or "Inactive". Listed below each server's entry is an entry for each domain (when applicable) and the port and IP address currently in use by that server or domain. The shortcut menu provides a control for toggling each server between the Active and Inactive state. When a server is inactive its icon will turn red.
Event Tracking and Logging
The default right-hand pane of the main interface contains a group of tabs that display
MDaemon's current actions and the status of its various servers and resources, and they are continually updated to reflect current server conditions. Each active session and server action is logged onto the appropriate tab once each action is complete. The information displayed on these tabs is mirrored in the log files kept in the Logs directory, if you have chosen to log such activity.
The primary pane of MDaemon's GUI contains the following tabs:
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
74 MDaemon Messaging Server 17.0
System — at program startup, the System tab displays a log of the Initialization
Process, which can alert you to possible problems with MDaemon's configuration or status. It also displays activity such as enabling/disabling any of MDaemon's various servers.
Statistics — this tab will display a server statistics report corresponding to the information contain in the various root node counters on the Stats tab in the
Stats and Tools pane. If you wish to change the font or font size used for this report you can do so by editing the following keys in the MDaemon.ini file:
[ReportWindow]
DefFontFace=Courier New
DefFontHeigh=15
DefFontWidth=7
Further, at midnight each night, the Postmaster and all addresses listed on the
447
screen of the Content Filter will get a copy of this report via email. This is the same report that is generated when you use the "Status" email command listed in
769
. If you do not wish this report to be sent, then disable the "Send stats report to postmaster at midnight" option located on the
422
screen under Preferences.
Routing — displays the routing information (To, From, Message ID, and so on) for each message that is parsed by MDaemon.
Security — click this tab and several other security-related tabs will appear above it.
Content Filter — MDaemon's
431
operations are listed on this tab.
When a message matches the criteria of one of the Content Filter's message rules, the relevant information related to that message and the actions taken are logged here.
AntiVirus — AntiVirus operations are listed on this tab. When a message is scanned for viruses, the relevant information related to that message and the action taken is logged here.
AntiSpam — displays all of MDaemon's
473
and prevention activities.
MDSpamD — lists all activity of the
484

WorldClient
WorldClient — displays WorldClient's mail activities.
SyncML — this tab mirrors the data contained in the SyncML log file.
ActiveSync — this tab displays ActiveSync activity.
Queues — this tab gives access to another row of tabs above it with one tab corresponding to each message queue, such as: Local, Remote, Holding,
Quarantine, Bayesian Spam, and so on.
Plug-ins — displays all activities related to any MDaemon plug-ins.
Active Directory — displays all Active Directory related activity.
Sessions — click this tab and several other tabs will appear above it. These tabs display an entry for each active connection to MDaemon. Whether the connection is SMTP in or out, POP in or out, IMAP, WorldClient, or ActiveSync, information about each active session is displayed here. Double-click on an active session to display a
78
, which displays the transcript of the SMTP session as it progresses.
The information displayed on these tabs has no affect on the amount of data that is actually stored in the log files.
However, MDaemon does support a great deal of flexibility with regard to the amount and type of information that is logged in those files. See the
139
dialog for more information on logging options.
Event Tracking Window's Shortcut Menu
If you right-click in any of the Event Tracking pane's tabs it will open a shortcut menu.
Various options are provided on this menu that can be used to select, copy, delete, or save the contents of a given tab. The menu's Print/Copy option will open any currently selected text in Notepad, which can then be used to print the data or save it to a file.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
76 MDaemon Messaging Server 17.0
The Delete option will delete the text you have selected. The Search option will open a window in which you can specify a word or phrase to search for in the log files.
MDaemon will search all log files for the text string and then all session transcripts containing that string will be combined into a single file and opened in Notepad for your review. A practical use of this feature would be to search for a particular Message-ID, which would provide a compilation from all the logs of all session transcripts containing that Message-ID.

3.6 MDaemon's SMTP Work Flow
When an incoming SMTP connection is made, MDaemon goes through a complex series of processing steps to determine whether to accept the message for delivery, and what to do with it once it is accepted. The following chart is a graphical representation of this work flow for inbound SMTP messages.
The extent to which these steps are executed is dependent upon your particular configuration. One or more steps might be skipped if a given feature is disabled in your configuration.

4.1.1.1 Delivery
Message Routing
Send all outbound email directly to the recipient
' s mail server
When this option is chosen, MDaemon will attempt to deliver mail directly instead of passing it to another host. MDaemon will place undeliverable messages into its retry system and continue to attempt to deliver them according to the parameters and time intervals that you set on the
742
screen of the Mail Queues dialog.
Send all outbound email to a smart host
Select this option if you want outbound email, regardless of its destination domain, to be spooled to another host or server for routed delivery. If selected, outbound email will be sent to the Default Smart Host specified below. Typically, this feature is useful during high volume periods when direct message delivery would result in an excessive taxation of server resources. If a message cannot be delivered to the designated server then it will be moved into the retry system and MDaemon will continue to attempt to deliver it according to the parameters and time intervals that
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 83
you set on the
742
screen of the Mail Queues dialog.
Send all email directly first, and then to smart hosts if there are problems
This option is a combination of the previous two delivery options. First MDaemon will attempt to deliver outbound email directly to the server, but if it is unable to deliver it, it will instead send the email to the Default Smart Host specified below.
Undeliverable mail is email destined for hosts that could not be resolved to an actual
IP address (such as an unregistered gateway to a remote network) or email destined for a host that was resolved properly but could not be connected to directly or is refusing direct connections. Rather than return such mail to its sender, this option causes MDaemon to pass the message off to a more powerful MTA. Sometimes the mail system run by your ISP may have routed methods of mail delivery to which your local server may not have direct access. If, however, a message cannot be delivered to the designated smart host then it will be moved to into the retry system and MDaemon will continue to attempt to deliver it according to the parameters and time intervals that you set on the
742
screen of the Mail Queues dialog.
At each subsequent delivery attempt, MDaemon will again first try to deliver the message directly to its recipient and then to the designated smart host.
Default Smart Host
Default smart host
Specify your ISP or mail host
' s name or IP address here. This is generally the SMTP server on your ISP.
Do not enter MDaemon's Default Domain or IP addresses into this text box. This entry should be an ISP or other mail server that can relay mail for you.
Treat default smart host as domain name and deliver to its MX hosts
Enable this option if you want MDaemon to treat the Default smart host as a domain name, querying its DNS record and delivering to its MX hosts.
Use SMTP authentication
Click this check box and enter your login credentials below if the Default Smart Host requires authentication. These login credentials will be used for all outbound SMTP messages sent to the smart host. If, however, you choose to use the Allow per-
account authentication option below, then MDaemon will authenticate to the host separately for each message, using the sending account’s Smart Host Access credentials designated on the
605
screen of the Account Editor.
User name
Enter your user name or login here.
Password
Use this option to specify your smart host login password.
Perform a POP check first
If your smart host requires a POP3 check before it will accept messages from you,
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
84 MDaemon Messaging Server 17.0
click this check box and enter your required credentials below.
Host or IP
Enter the host or IP address to which you wish to connect.
User name
This is the POP account
' s login or account name.
Password
This is the POP account
' s password.
Allow per-account authentication
Click this checkbox if you wish to use per-account authentication for outbound
SMTP messages sent to the Default Smart Host specified above. Instead of using the User name and Password credentials provided here, each account’s Smart Host
Access credentials, designated on the
605
screen, will be used instead.
If no smart host credentials have been designated for a given account, the above credentials will be used instead.
If you wish to configure per-account authentication to use each account’s Email
password instead of its optional Smart host password, then you can do so by editing the following key in the
MDaemon.ini
file:
[AUTH]
ISPAUTHUsePasswords=Yes (default No)
Enabling the
ISPAUTHUsePasswords=Yes
option will over time effectively communicate all your accounts’ local mail passwords to your smart host. This could pose a risk to mail security, since it is providing sensitive information to another server. You should not use this option unless you are using a smart host that you absolutely trust and you believe it is necessary to do so. Further, you should note that if you use this option and give your users permission to change their
Email password via WorldClient or some other means, then changing the Email password will also effectively change the
Smart host password. This could cause smart host authentication to fail for an account when its Email password is changed locally but the corresponding Smart host password isn't changed at your smart host.
Abort delivery if SMTP RCPT command receives a 5xx error
Enable this option if you wish MDaemon to abort its attempt to deliver a message when it receives a 5xx fatal error in response to the SMTP RCPT command. This option is disabled by default.
Bounce message if receiving domain has no MX records
Ordinarily when MDaemon checks the receiving domain's DNS records, it will look for
MX records and then for an A record when no MX records are found. If neither are found then it will bounce the message back to the sender as undeliverable. Click this
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 85
option if you want MDaemon to immediately bounce the message when no MX record is found, instead of allowing it to then look for an A record also. This option is
Disabled by default.
Bounce message on first 5XX error from any of receiving domain's MX hosts
When this checkbox is enabled, MDaemon will return/bounce the message when it receives a 5xx fatal error response from an MX host. Consequently, it won’t continue trying to deliver the message to any subsequent MX hosts that may be designated for the recipient’s domain. If this option is disabled, MDaemon won’t bounce the message as long as at least one of the MX hosts returns a 4xx non-fatal error response. This option is enabled by default.
Bounce message on 5xx errors from smart hosts
Use this option if you wish to return/bounce a message when it receives a 5xx fatal error response from your smart hosts.

SMTP Server
Enable VRFY
Click this switch if you wish to respond to SMTP VRFY commands. This command is sometimes used by servers that use an SMTP call forward or call back feature to attempt to confirm the validity of email addresses on your server. This is disabled by default.
Enable EXPN
Click this checkbox if you want MDaemon to honor EXPN commands.
Enable APOP & CRAM-MD5
By default MDaemon
' s servers (POP, IMAP, and so on) honor the APOP and CRAM-
MD5 methods of authentication. These methods provide extra security by making it possible for users to be authenticated without sending clear text passwords. Clear this checkbox if you do not wish to allow APOP or CRAM-MD5.
Silently discard duplicate RCPT values
Enable this option if you want the SMTP server to ignore duplicate recipients in the same SMTP session. MDaemon will accept and then discard the duplicate recipients.
This option is disabled by default.
Refuse messages which violate RFC standards
Enable this option if you wish to reject messages during the SMTP process that are not compliant to RFC internet standards. To pass the compliance test the message must:
1. Be greater than 32 bytes in size (the minimum size necessary to include all required parts).
2. Have either a FROM: or a SENDER: header.
3. Have no more than one FROM: header.
4. Have no more than one SUBJECT: header, though no subject header is required.
Messages using authenticated sessions or from trusted domains or IP addresses are exempt from this requirement.
SSL negotiation failures will retry without SSL for up to one hour
This option allows you to temporarily white list host IPs that encounter an SSL error during an outbound SMTP session. The white list is reset every hour.
Refuse messages larger than [xx] KB (0=no limit)
Setting a value here will prevent MDaemon from accepting or processing mail that exceeds a certain fixed size. When this option is enabled MDaemon will attempt to use the ESMTP SIZE command specified in RFC-1870. If the sending agent supports this SMTP extension then MDaemon will determine the message size prior to its actual delivery and will refuse the message immediately. If the sending agent does not support this SMTP extension then MDaemon will have to begin acceptance of the message, track its size periodically during transfer, and finally refuse to deliver

...except when SMTP AUTH is successfully used
Check this box if you wish to exempt messages from the message size limitation when the SMTP session is authenticated.
Max RCPT commands allowed
Use this option if you wish to limit the number of RCPT commands that can be sent per message. Use "0" if you do not wish to set a limit.
Close session if reached
Check this box if you wish to close the session immediately if the maximum allowed number of RCPT commands is reached.
Max RSET commands allowed
Use this option if you wish to set a maximum number of RSET commands allowed in an SMTP session (default is 20). Use "0" if you do not wish to set a limit.
Close session if reached
Check this box if you wish to close the session immediately if the maximum allowed number of RSET commands is reached.
Server Settings
POP server deletes mail on DELE command
Click this option if you wish MDaemon to delete messages immediately when they are retrieved and the DELE command is received, even if the POP session does not complete properly.
IMAP server supports COMPRESS command
Click this box if you wish to support the IMAP COMPRESS extension (RFC 4978), which compresses all data sent to and from the client. COMPRESS will increase CPU and memory usage per IMAP session.

4.1.1.3 Ports
SMTP, ODMR, & MSA Ports (some features require MDaemon PRO)
SMTP inbound port
MDaemon will monitor this TCP port for incoming connections from SMTP clients. This is the main SMTP port, which in most cases should be left at the default setting of port 25.
SMTP outbound port
This port will be used when mail is sent to other SMTP servers.
MSA inbound port
This is a Message Submission Agent (MSA) port that can be used by your users as an alternative to the SMTP inbound port specified above. Transmission on this port requires AUTH, therefore users sending on that port must configure their mail clients appropriately to ensure that their connections are authenticated. Further, because some ISPs block port 25, your remote users might be able to circumvent that restriction by using the MSA port instead. If you do not wish to designate an MSA port then set the value to "0" to disable it.
Connections to the MSA port are exempt from PTR and reverse lookups, Host and IP screening, the IP Shield, and Tarpitting.

Bind to new port values now
When you alter the values of any of the port settings you will need to press this button to have your changes take immediate effect. Otherwise, your changes will not be put into place until the next time the server is started.
The preceding port settings are critical for proper server operation and should not be altered unless you are certain that you must do so. Being able to configure the ports that
MDaemon uses will allow you to configure the server to operate with proxy systems or other software services that require certain port numbers.
An IP address (a machine) has only one of each available port.
If one program attempts to gain access to a port that is already in use by another program, an error message will inform the user that the requested address (IP:PORT) is already in use.

When this option is selected, MDaemon will use all DNS servers found within your
Windows TCP/IP configuration. MDaemon will try each DNS server once per lookup operation and in sequence until it exhausts the complete list of DNS servers or finds the first one that works. If you include additional DNS servers in the Manually
configured DNS Servers option below, MDaemon will try those servers as well.
Finally, at startup the System log will display each DNS server and indicate its source (i.e. manually configured or taken from Windows).
Reload DNS server hourly
Check this box if you wish to reload the DNS server every hour. This is disabled by default.
Manually configured DNS servers
MDaemon will use all DNS servers specified here when performing DNS lookups.
MDaemon will try each server once per lookup operation and in sequence until it exhausts the complete list of DNS servers or finds the first one that works. If you enable the Use Windows DNS servers option above, MDaemon will also query all DNS servers found within your Windows TCP/IP configuration. Finally, at startup the
System log will display each DNS server and indicate its source (i.e. manually configured or taken from Windows).
Local Cache Files
Hosts file...
Before querying the DNS servers, MDaemon will first attempt to resolve an address by processing the Windows HOSTS file. If this file contains the IP address of the domain in question, MDaemon will not need to query the DNS server.
You must enter the complete path and filename rather than just the filename. MDaemon will attempt to use the following value as the default location of this file:
[drive]:\windows\system32\drivers\etc\hosts
The HOSTS file is a Windows file that contains the A-record or primary IP address for domain names. MDaemon also allows you to specify MX-record IP addresses within a file called
MXCACHE.DAT. This file can be found within the MDaemon\APP
\ subdirectory. Load the MXCACHE.DAT file into a text editor and read the comments at the top of the file for more information.

Wait xx seconds for protocol dialog to start
Once a connection has been established with a remote host, this is the number of seconds that MDaemon will wait for the remote host to begin the SMTP or POP3 protocol dialog. If the remote host does not begin the protocol session within this time frame, MDaemon will send the message to a specified smart host or place it into the retry system, depending upon which option you have chosen on the

SMTP and POP3 sessions timeout after XX inactive minutes
If a successfully connected and operating session remains inactive (no i/o) for this length of time, MDaemon will abort the transaction. MDaemon will try again at the next scheduled processing interval.
Wait on response to SMTP DATA command for XX minutes
This option governs how long MDaemon will wait for the "
250 Ok

4.1.1.8 Sessions
SMTP
Maximum concurrent SMTP outbound sessions
The value entered here represents the maximum possible outbound SMTP sessions that will be created when it is time to send outbound mail. Each session will send outbound messages until either the queue is empty or the
Maximum SMTP outbound messages spooled per session
setting has been reached. For example, if the outbound mail queue has twenty messages waiting when it is time to send mail and the value of this setting is five, then five sessions will be simultaneously created and each will consecutively deliver four messages.
This option is set to 30 by default, but you may wish to experiment with the number of sessions in order to find the setting that will yield the best performance for your bandwidth. It is possible to specify so many sessions that your bandwidth will be overloaded or your Windows machine will run out of resources and you will lose delivery efficiency. Remember, each SMTP session created by MDaemon will deliver messages consecutively and therefore four sessions delivering two messages each might perform better and faster than eight threads delivering only one message each. A good place to start would be five to ten threads when using a 56k modem and twenty to thirty for broadband
Maximum concurrent SMTP inbound sessions
This value controls the number of concurrent inbound SMTP sessions that the server

will accept before it begins responding with a "Server Too Busy" message. The default value is 50.
Maximum concurrent MSA inbound sessions
Use this option to designate the maximum number of concurrent mail submission agent (MSA) inbound sessions allowed.
Maximum SMTP outbound messages spooled per session
This setting places a limit on the number of individual messages that each session will send before it stops delivering mail and frees itself from memory. Ordinarily, you should leave this control set to zero, which will cause each session to continue delivering messages until the queue is empty.
Cache SMTP connection failures for this many minutes (0 = never)
When an SMTP connection to a given host fails, MDaemon will cease trying to connect to that host for the number of minutes specified in this option. This can prevent MDaemon from needlessly attempting to connect to a problem host over and over again when, for example, it has multiple messages designated for that host and yet discovers that it is down when making the first delivery attempt. The default setting is “5” minutes. Use “0” if you do not wish to cache SMTP failures.
Maximum simultaneous connections to any single IP (0 = unlimited)
Use this option to limit the number of simultaneous connections that will be allowed to a single IP address during mail delivery. Use “0” if you do not wish to limit simultaneous connections.
This option is useful to prevent making too many connections at once to various IP addresses. During delivery, if a message would require a connection to an IP that would exceed this connection limit, then the connection is skipped and the next MX host (or smart host) is used. If no additional hosts are available the message is queued for the next delivery cycle. By default, this option is disabled, which preserves existing behavior. Also by default, connections to trusted IP addresses are exempt from this feature. However, if you’d like to enforce it for trusted IPs you can set the following in the
MDaemon.ini
file:
[Sessions]
TrustedIPsUseConnectionLimit=Yes (default No)
Also by default, connections to IP addresses reserved for intranet use are exempt from this feature. These are
127.0.0.*
,
192.168.*.*
,
10.*.*.*
, and
172.16.0.0/12
. However, if you’d like to enforce it for reserved IP addresses you can set the following in the

Use multiple RCPT commands when sending mail
By default MDaemon uses smart spooling, that is it will use multiple RCPT commands within a session when sending mail. Uncheck this box if you wish to use only one
RCPT command per session.

White list
This button opens the Smart Spooling White List. When MDaemon sends messages to domains on this list, it will NOT use smart spooling; only one RCPT command will be used per session.
POP3 & IMAP
Maximum concurrent MultiPOP outbound sessions
The value entered here represents the maximum possible outbound POP sessions that will be created when it is time to collect MultiPOP mail. Each session will collect this type of mail until all MultiPOP servers have been processed, and all mail has been collected. For example, if there are fifteen MultiPOP sessions amongst all of your users and the value of this setting is set to three, then each session will collect mail from five MultiPOP sources.
You should experiment with the number of sessions to determine what number will yield the best performance for your bandwidth. It is possible to specify so many sessions that your bandwidth will be overloaded, or your Windows machine will run out of resources and you will lose processing efficiency. Remember that each POP sessions created by MDaemon will collect mail until all sources have been exhausted.
Therefore, four sessions collecting mail from twenty sources might perform better and faster than twenty sessions collecting from a single source.
Maximum concurrent POP3 inbound sessions

4.1.1.9 Mail Release
Setup Menu 99
Signal remote host to release waiting mail
When it is time to process remote mail MDaemon can connect to any server on any port and send any string that you wish to send. This is useful when you need to signal a remote server to release your mail by sending some string to them. For example,
ATRN
,
ETRN
, or
QSND
. You can also use this feature when a
FINGER
or
TELNET
session is briefly required in order for your remote host or ISP to determine that you are online.
Host name or IP
This is the host that will be signaled to release your mail.
Port
Enter the port on which you wish to make the connection. The default is 25 (the
SMTP port), which is appropriate for the
ETRN
or
QSND
signaling method. Port 366 is typically used for
ATRN
, and port 79 is used for
FINGER
.
Send this string of text to host (leave blank if merely connecting is enough)
This control is for specifying the text string that needs to be sent in order for your mail to be released. For example, the
ETRN
method requires the text "
ETRN
" followed by the domain name of the site being queued. Other methods require different text to be sent. Consult your ISP if you need more information on what to send to unlock your mail queue. If you have a choice of the method to use, we recommend using
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
100 MDaemon Messaging Server 17.0
100
whenever possible. ODMR requires the ATRN command to be used in this option.
Send signal once every [xx] times remote mail is processed (0=every time)
By default the dequeue signal will be sent each time that remote mail is processed.
Entering a number into this control will prevent the dequeue signal from being sent every time. It will be sent every x number of times as designated. For example, setting this value to "3" would cause the signal to be sent every third time that remote mail is processed.
Send "EHLO" before sending the text string
If you enable this checkbox then you should be connecting to an SMTP server to signal release of your mail. This switch causes an SMTP session to be initiated with the specified host and allows the session to progress just beyond the SMTP "
EHLO
" stage before sending the unlock string.
Authenticate before sending the text string (required for ATRN)
As a security measure, some hosts or servers require clients to authenticate using ESMTP AUTH before releasing waiting messages. If this is the case for your mail host, click this checkbox and enter the required authentication credentials below.
Authentication is required when using the ATRN command to dequeue your email.
Logon
Enter the AUTH logon parameter here that is required by your host.
Password
Enter the AUTH password here.
4.1.1.9.1 On-Demand Mail Relay (ODMR)
When you require a queue/dequeue method for hosting and releasing your email, we recommend using On-Demand Mail Relay (ODMR) whenever possible. This method is superior to ETRN and other methods in that in requires authentication before mail is released. Further, it utilizes an ESMTP command called
ATRN
that does not require the client to have a static IP address, because it immediately reverses the flow of data between the client and server, releasing the messages without having to make a new connection to do so (unlike ETRN).
MDaemon fully supports ODMR on the client side via using the
ATRN
command and authentication controls on the
99
screen, and on the server side using the
Domain Gateways features on the
207
screen of the Gateway Editor.
Some mail servers do not support ODMR, therefore you should check with your provider before attempting to use it.

4.1.1.10 Archiving
Setup Menu 101
Use this feature to archive all inbound or outbound messages to a folder. The default location for this folder is C:\MDaemon\Archives\Email\, but you can set it to any folder you choose. You can choose to archive inbound messages that are to your local users, outbound messages from your local users, or both. Mailing list messages, messages being relayed, and those with a virus will not be archived. Inbound and outbound messages will be stored in \In\ and \Out\ subfolders, respectively. They can be further subdivided by using the ...archive based on recipient address and ...archive
based on sender address options below. Also, separate archives can be maintained for each domain by using the Provide separate archives for each MDaemon domain option.
Archived messages are saved in the final state in which they appear in the local user's mail folder, or in the "ready to be delivered" state for outbound messages. This means that if you, for example, have the content filter make some change to a message, such as adding a header to it, then the archived message will contain that change.
To browse the archive folder use one of your mail accounts (or create a new one) and point its

4.1.1.12 Message Recall
Simple Message Recall
MDaemon Pro has a simple message recall system that you can use to delay incoming messages sent by authenticated local users for 1 to 15 minutes. During that delay period the messages are simply left in the inbound mail queue. This provides a short period during which a user can attempt to stop a message from being delivered. Once the delay period expires the message is delivered normally.
To recall a message a user can simply log in to WorldClient and click the Recall button that will be displayed when viewing a recently sent message in the Sent Items folder. If clicked before the recall time limit expires, WorldClient will send a RECALL message to
MDaemon. Alternatively, the user can go the the Sent Items folder in his mail client, locate the message he wishes to recall, and then "Forward as Attachment" the message to the [email protected] system account, using "RECALL" as the message's Subject. Another alternative is to view the message's headers, copy the
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 105
"Message-ID: <message-ID value>" header, and create a new message with "RECALL
Message-ID: <message-ID value>"
in the subject (without the quotes). If both alternatives are used within the same recall message, only the message ID option will be used.
Regardless of the chosen recall method, MDaemon will send an email back to the user, saying whether or not the recall was successful. When a message is successfully recalled, MDaemon deletes the message from the inbound queue as if it had never been sent. All recall processing is logged to MDeamon's Routing log.
Enable message recall
Click this checkbox to activate the message recall system. The option is disabled by default.
Delay messages for this many minutes XX (1-15 minutes)
This is the number of minutes that MDaemon will hold incoming messages from authenticated local users. If a RECALL message is received during the delay period then MDaemon will delete the referenced message. This option can be set to 1-15 minutes. 1 minutes is the default setting.
Deferred Delivery
The Deferred Delivery option allows authenticated clients to send messages to be delivered at a scheduled date and time. WorldClient includes this option, allowing users to click "Send Later" and specify the date and time to send the message. The message includes the Deferred-Delivery message header containing the date and time to attempt to deliver the message. If the Message Recall option is enabled and a recall request is received for a message scheduled for deferred delivery, MDaemon will attempt to remove the recalled message.
Enable deferred delivery
Enable this option if you wish to allow authenticated clients to use the Deferred-
Delivery
header to schedule messages for deferred delivery. When this option is enabled, WorldClient users will have the Send Later option available in the
WorldClient and Lookout themes. The option is disabled by default.

The following applies globally anywhere within MDaemon where you are allowed to specify a host to forward, copy, or send email to. If you enclose the host in brackets (e.g.
[example.com]
), MDaemon will skip MX record lookups when delivering to that host. For example, if this option contained
"

4.1.1.14 Domain Sharing
Domain Sharing is a feature which allows you to split a domain's users across multiple servers. This makes it possible for you to have MDaemon servers running in different locations, all using the same domain names but with different user accounts. One portion of your domains' user accounts are hosted on one server while another portion of them are hosted on one or more other servers. The Domain Sharing dialog is used to specify where each of these other servers is located. Then, when an incoming message arrives for a local user who does not have a local mailbox, Domain Sharing will use
Minger to query the other servers in order to discover whether or not that user has an account on one of them. If the address is found to be valid, MDaemon will accept the message and route it to the server where the account is located.
For example, you could have offices in multiple cities and choose to use Domain Sharing to allow every employee to have an email address ending with, "@example.com." Each office's MDaemon would host a portion of example.com's email, having accounts only for the local employees who work in that office. Then, every office would be configured to use Domain Sharing, so that everyone's messages would get routed to the correct office.
Because Domain Sharing uses
729
to verify addresses, Minger must be enabled and properly configured on each server in order for queries to function. If, however, an error occurs during a Minger query, such as when one of the servers is temporarily unavailable, MDaemon will respond with a "451" temporary error code so that the sending server can try to deliver the message again later. Further, once an address has been verified, it will be cached for five days so that MDaemon can immediately accept
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 109
future messages for that address and begin attempting to route those messages to the proper host.
Finally, to avoid potential problems that could occur if the same account were created on multiple servers, MDaemon will query all of the Domain Sharing servers before creating any new account.
There is an option called "Minger verification lookups also
trigger Domain Sharing lookups," located on the Gateway
Editor's
211
screen. This option can be used to cause
MDaemon to also query your Domain Sharing hosts whenever
202
is used by a Gateway.

(this is not the same as the Minger port below).
Minger port
This is the port that Minger will use when querying this host. The default port is
4069.
Minger password (optional)
If the host that you are adding requires a Minger password, enter it here. Setting up
Minger to require a password is optional, but it is recommended.
Add
After entering the host or IP, port, and password, click this button to add the new
Domain Sharing entry to the list.
Do not send Domain Sharing mail to smart host on delivery errors
When this option is enabled, if MDaemon encounters an error while attempting to deliver Domain Sharing email (e.g. such as when the Domain Sharing host is offline), the email will be kept in the
742
rather than sent to the
82
. Sending these emails to the smart host can often lead to a mail loop. This option is enabled by default.

4.1.1.16 IP Cache
In order to speed message delivery and shorten mail processing time, MDaemon caches the IP addresses of all hosts with which it comes in contact. These IPs are stored and then the cache is checked each time MDaemon requires a DNS resolution on a host name. If the host name needing resolution is found in the IP cache then the DNS lookup is skipped, which can save a surprising amount of processing time. The settings in this window allow you to manipulate the parameters under which the cache will operate.

This is the default value in minutes that an entry will remain in the IP Cache. Once the entry has been in the IP Cache for this number of minutes, MDaemon will remove it. If you want to set a permanent entry in the IP Cache then designate the
Default time to live
as 9999.

4.1.1.19 Public & Shared Folders
MDaemon supports shared Public and User IMAP folders. Public folders (managed from the
251
) are extra folders that do not belong to any particular account but can be made available to multiple IMAP users. User folders are IMAP folders that belong to individual MDaemon accounts. Each shared folder, whether public or user, must have a list of MDaemon users associated with it, and only members of that access list may access it via WorldClient or an IMAP email client.
When IMAP users access their list of personal folders, they will also see the shared public and shared user folders to which they have been given access. In this way certain mail folders can be shared by multiple users but still require each user
' s individual logon credentials. Further, having access to a folder doesn't necessarily mean having full read/write or administrative access to it. Specific access rights can be granted to individual users, thus allowing you to set different levels of access for each one. For example, you might allow some users to delete messages while restricting that from others.
Once a public or user IMAP folder has been created you can use the Content Filter to set criteria by which certain messages are moved into that folder. For example, it might be useful to make a filter rule that would cause messages containing [email protected]
in the
TO:
header to be moved into the
Support
public folder.
The
433
"
Move Message to Public Folders...
" and "
Copy
Message to Folder...
" make this possible. For shared user folders, you can use your
623
to route specific messages to them. In addition to using
Content Filters and IMAP filters, you can associate a specific account with a shared folder so that messages destined for that "Submission Address" will be automatically routed to the shared folder. However, only users who have been granted "post" permission to the folder will be able to send to that address.
For added convenience, the Mailing List editor also contains a
241
screen that makes it possible for you to configure a public folder for use with a particular list.
If you enable this feature then a copy of each list message will be placed into the specified public folder. All public folders are stored in the
\Public Folders\
directory within the MDaemon directory hierarchy.
WorldClient Documents Folders
The WorldClient themes support document sharing using document folders. Document folders have full
253
support like other shared folders, which can be used to set permissions and sharing rules, and any types of files can be shared through the system. WorldClient users can upload files to their document folders using the built-in tools. When using the LookOut theme, browsers that support the HTML5
Drag and Drop API, such as Chrome and Firefox, can also upload files by dragging them from the desktop into the browser window. Filenames can be searched and renamed, and files can be attached to new messages that are being composed.
You can enable/disable the documents folders (and other shared folders) on a perdomain and per-user basis by editing the \WorldClient\Domains.ini file and individual \Users\..\WC\user.ini files respectively. You can configure both default settings and customized settings, which will override the defaults. For example:
[Default:UserDefaults]
DocumentsFolderName=Documents
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 119
EnableDocuments=Yes
[example.com:UserDefaults]
DocumentsFolderName=Example Documents
EnableDocuments=Yes
[superControllingDomain.gov:UserDefaults]
EnableDocuments=No
EnableCalendar=No
EnableNotes=No
EnableTasks=No
Setting a Maximum File Size
You can limit the size of individual files that can be uploaded to documents folders by adding this key to the domains.ini file: MaxAttachmentSize=<value in KB> The default value is 0, which means there is no limit.
Blocking or Allowing File Types
To prevent certain file types from being uploaded to the documents folder, add the
BlockFileTypes=
key to the domains.ini file, listing the files types you wish to block separated by a space or comma. For example, "BlockFileTypes=exe dll js".
To allow only certain file types to be uploaded to the documents folder, add the
AllowFileTypes=
key to the domains.ini file, listing the files types you wish to allow separated by a space or comma. For example, "AllowFileTypes=jpg png doc docx xls xlsx
".
When both keys are used, priority is given to blocked files when there is a conflict; if an extension is in both lists then that extension will be blocked. If a key is used without a value (i.e. no list of extensions), then that key will not be used. File extensions can include a "." (e.g. .exe .dll), but it isn't required.

4.1.2 DomainPOP
Use DomainPOP Mail Collection ("S etup » S erv er S etti ng s » Domai nPOP") to configure
MDaemon to download mail from a remote POP mailbox for redistribution to your users.
This feature works by using the POP3 protocol to download all the mail found in the
ISP
' s POP mailbox associated with the specified logon. Once collected, the messages are parsed according to the settings provided on this dialog and then placed in user mailboxes or the remote mail queue for MDaemon to deliver, just as if the messages had arrived at the server using conventional SMTP transactions.
It is important to note that messages stored in mailboxes and retrieved using the POP3 protocol will be devoid of the important routing information (sometimes called the message
' s "envelope") that would ordinarily be supplied had the messages been delivered using the more powerful SMTP protocol. Without this routing information,
MDaemon is forced to "read" the message and examine the headers in an attempt to determine to whom the message was originally intended. This is not an exact science
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
122 MDaemon Messaging Server 17.0
to say the least. Message headers are sometimes notorious for their lack of sufficient information needed to determine the intended recipient. This lack of what would seem to be a fundamental characteristic of an email message - the recipient - may seem surprising but one must keep in mind that the message was never intended to be delivered to its recipient using the POP protocol. With SMTP, the contents of the message are irrelevant since the protocol itself dictates specifically to the server, during the mail transaction, the intended recipient of the message.
In order to allow for POP retrieval and delivery of mail messages in a reliable and consistent way, MDaemon employs a powerful suite of header processing options.
When MDaemon downloads a message from a remote POP source it immediately parses all the relevant headers within that message and builds a collection of potential recipients. Every email address found in the headers that MDaemon inspects is included in the collection.
Once this process is complete, MDaemon
' s collection of recipients is divided into local and remote sets. Further, all addresses that are parsed and placed into the collection of potential recipients are processed through the
703
translator before being divided into local and remote sets. Every member of the local set (addresses with a domain that matches one of MDaemon's local domains) will receive a copy of the message. What happens to the remote set is governed by the settings in this dialog.
You can elect to simply ignore these addresses, forward a summary listing of them to the postmaster, or honor them — in which case MDaemon will actually deliver a copy of the message to the remote recipient. Only under rare circumstances would the need to deliver these messages to remote recipients be warranted.
Care must be taken to prevent duplicate messages or endlessly looping mail delivery cycles. A common problem that results from the loss of the SMTP envelope manifests itself with mailing list mail. Typically, messages distributed by a mailing list do not contain within the message body any reference to the addresses of the recipients.
Rather, the list engine simply inserts the name of the mailing list into the
TO:
field. This presents an immediate problem: if the
TO:
field contains the name of the mailing list then the potential exists for MDaemon to download this message, parse the
TO:
field
(which will yield the name of the mailing list), and then dispatch the message right back to the same list. This would in turn deliver another copy of the same message back to the POP mailbox from which MDaemon downloaded the original message — thus starting the whole cycle over again. To cope with such problems mail administrators must take care to use the tools and settings that MDaemon provides to either delete mailing list mail or perhaps alias it in such a way that it will be delivered to the proper local recipient(s). You could also utilize the Routing Rules or Content Filters to deliver the message to the correct recipient(s).
Additional concerns when employing this sort of mail collection scheme revolve around the issue of unwanted message duplication. It is very easy for mail that is delivered to the ISP
' s POP mailbox using SMTP to generate unwanted duplicates, once it has been collected using DomainPOP. For example, suppose a message is sent to someone at your domain and a carbon copy is sent to another person at the same domain. In this situation, SMTP will deliver
two
copies of the same message to your ISP
' s mailbox — one for each recipient. Each of the two message files will contain references to
both
recipients — one in the
TO:
field and the other in the
CC:
field. MDaemon will collect each of these two identical message files and parse both addresses from each of them.
This would result in both recipients receiving one unwanted duplicate message. To guard against this sort of duplication MDaemon uses a control which allows you to
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 123
specify a header that MDaemon will use to check for duplication. The
Message-ID
field is ideal for this. In the above example, both messages are identical and will therefore contain the same
Message-ID
field value. MDaemon can use this value to identify and remove the second message during the download stage before it can be parsed for address information.
As a final measure guarding against duplicate messages and endless looping delivery cycles, MDaemon employs a means for detecting how many trips or "hops" a message has made through the transport system. Each time an SMTP mail server processes a message it "stamps" the message with a "Received" header. MDaemon counts all such headers when it encounters a message for the first time. If the total number of mail servers exceeds a specified value, it is likely the message is caught in a delivery loop and should be taken out of the mail stream and moved to the bad message directory.
This value can be configured under the
742
.

Parse "subject:" header for address inside "(" and ")" characters
When this is selected and MDaemon finds an address contained in "( )" in the
"Subject:" header of a message, this address will be added to the message
' s list of recipients along with any other parsed addresses.
Parse "Received" headers for email addresses
It is possible to store the recipient information ordinarily found only within the message’s envelope in the "Received" message headers. This makes it possible for parsers of the mail message to be able to glean the actual recipient address by merely inspecting the Received headers later. Click this checkbox if you wish to parse valid addresses from all of the "received" headers found within the mail message.
Skip over the first xx "received" headers
In some server configurations you may wish to parse Received headers but need to skip the first few of them. This setting allows you to enter the number of
"Received" headers that MD will skip over before beginning its parsing.
Stop parsing if "Received" yields a valid local address
If while parsing a "received" header MDaemon detects a valid local address, this switch will cause all further parsing to stop and MDaemon will not search the message for more potential delivery addresses.

Address Filtering
Always strip the following text from all parsed addresses
Some hosts will stamp each message with a line that indicates who the recipient of the message should be, along with a bit of routing information appended to the address on either the left or right side. This stamp would be perfect to use for parsing the recipient address except that the additional routing information makes this impossible without a lot of account aliasing. Rather than do all that you can simply specify the value of this appended text in the edit control associated with this feature and MDaemon will strip any occurrence of this text from all addresses that it parses.
Ignore unknown local addresses parsed from messages
As mentioned above, the Domain Name Replacement feature will alter the domain name in all email addresses parsed from a message, converting it into the one you

TO: "Michael Mason" <[email protected]>
TO: Michael Mason <[email protected]>
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 133
Name Matching ignores the "[email protected]" portion of the address. It instead extracts the "Michael Mason" portion and checks to see if this is an MDaemon user.
If a match is found to an account
' s real name then that account
' s local email address is used for delivery purposes. If no match is made then MDaemon reverts to delivering the message to the email address parsed from the data
([email protected] in this example).
The real name portion of the address may not contain a comma, semi-colon, or colon character.
Only apply this feature if the address portion matches this value
This option allows you to specify an email address that must be present in the extracted data in order for the real name matching process to proceed. This allows you a measure of control over when the Name Matching feature will be employed.
For example, you can specify an address such as "[email protected]" and then only addresses matching this value will be candidates for Name Matching.
Suppose you specify "[email protected]" in this option. This means that "
TO:
'Michael Mason' <[email protected]>
" will be a candidate for Name Matching while "

will not.

This is the maximum size in kilobytes that a log file may reach. Once this size is reached, the log file is copied to "LOGFILENAME.01.OLD" and a new log is started. If
LOGFILENAME.01.OLD
already exists then the old file will either be deleted or renamed to "LOGFILENAME.02.OLD," depending on the value set in "Maximum
number of .OLD logs to keep" below. Use "0" in this option if you do not with to limit the size of the file. This option is set to "0" by default.

Maximum number of .OLD logs to keep (1-99)
When using the option above to limit log file size, this option governs how many iterations of a given .OLD log file will be kept before the oldest is deleted. These backup files are named, "LOGFILENAME.01.OLD," "LOGFILENAME.02.OLD," and so on, with the newest file always listed first. For example, SMTP(out).log.01.old has newer data than SMTP(out).log.02.old, etc. When the maximum number is reached, the oldest file is deleted when a new file is created.
Maximum days of AV update log data (0=no limit)
This option governs the maximum number of days that the Antivirus update log (i.e.
avupdate.log) will keep data. At midnight each night, and also whenever MDaemon starts after upgrading, older data will be deleted from the file. Use "0" in this option if you do not wish to set a time limit. By default the last 30 days of data are kept.
The AV update log is maintained by default and its size is limited to 5120 KB. If you wish to change its size limit or disable AV update logging, the options to do so are located on the
456
dialog, located at: Security »
AntiVirus » AV Updater » Configure updater » Misc.
Archiving
Archive log files older than [XX] days (0=never)
Click this option if you want MDaemon to archive each log file whose age exceeds the number of days specified. Each day at midnight, MDaemon will
ZIP
old
*.log
and
*.old
files and move them to the
\Logs\OldLogs\
subfolder (deleting the original files in the process). This process will not archive or delete files that are in use, nor will it archive files when the "
Log everything into a separate log file (MDaemonall.log)
" option is selected on the
139
screen.
Delete archives older than [XX] days (0=never)
Use this option if you want MDaemon to delete archived log files automatically when their age exceeds the number of days specified here. Use "0" in this option if you do not wish to delete archives automatically. Archive deletion occurs during the daily midnight cleanup event.
Archive now
Click this button to archive old log files immediately rather than waiting for MDaemon to archive them automatically at midnight.

Log multi-line protocol responses (like UIDL and LIST)
Sometimes the responses to protocol requests require more than one line of information. Click this checkbox if you want to log these additional lines.
Enabling this switch could potentially increase the amount of logged information a great deal. Because the number of lines in a response can't be determined in advance, and because some responses have great potential for "filling up" your log file with possibly unnecessary information (POP TOP, for example, lists the actual contents of the message), we do not recommend using this feature if log file size or verbosity is of concern to you.

Colorized Session Logs
On
73
, the tabs that display Routing, SMTP-in, SMTP-out,
IMAP, POP, MultiPOP, and DomainPOP activity can be colorized to help visually separate events during a session. This features is disabled by default, but can be enabled via the "Use colors when displaying mail session logs" option located at:
147
and
410
. The default text colors can be changed by editing the
[Colors]
section of the LogColors.dat file. See the chart below for a list of the default colors.
If you want to use colors but don't want to colorize one or more of the listed elements, set value of each of those elements to zero (for example, SpamFilter=0). This will cause the chosen elements to use the Default color. For Background and
SelectedBackground
, however, setting their values to zero doesn't work. If you want to change either of those elements you will have to provide a new color value. Color values are specified in hexadecimal using this form: "0xbbggrr", where "bb" is the relative intensity for blue, "gg" for green, and "rr" for red. For example,
"Error=0x0000ff" sets error text to red. Please note: this is the reverse of the traditional order for color codes, which is typically "rrggbb". If you make changes to the colors you must restart MDaemon or create of a file called COLORS.SEM and place it in MDaemon's \APP\ folder.

4.2 Domain Manager
MDaemon Pro contains full support for multiple domains, administered using the Domain
Manager. Here you can manager the domain names, IP addresses, account and message pruning settings, WorldClient settings, and other domain-specific options for your domains.
MDaemon supports both single and multiple IP addresses, and IP addresses can be unique to individual domains or shared between them. Further, several key features such as Accounts, Mailing Lists, and some Security Settings are on a per domain basis.
When you create an account, for example, you must specify the domain to which the new account belongs. The same goes for Mailing Lists. This also means that features such as the
550
and
513
are tied to domains individually.
Some features, such as
132
under
121
, are tied exclusively to the Default Domain. The Default Domain is also the domain displayed by default in various options, such as when creating new accounts or mailing lists. Further, to support MDaemon's handling of system messages, the following default
703
point several reserved mailbox names to MDaemon's default domain name rather than to its other domains:
MDaemon@$LOCALDOMAIN$ = MDaemon@<DefaultDomain> listserv@$LOCALDOMAIN$ = MDaemon@<DefaultDomain> listserver@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 153
list-serv@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
Finally, in order to support multiple domains, by default MDaemon requires users to use their full email address (e.g. "[email protected]") as their login value rather than using just the mailbox portion of the address (i.e. "user01"). Some very old mail clients, however, do not support using '@' in the login field. Therefore to accommodate those clients you can specify an alternate character on the
413
screen under
Preferences. Further, this value can be up to 10 characters long, making it possible to provide a string of characters to serve as the delimiter instead of only a single character such as
'
$
'
. For example, using
'.at.'
will allow you to make logon values of
" user02.at.example.com
". You can also disable the full email address requirement, allowing the use of only the mailbox portion of the address as the login value, but that is not recommended and can cause problems when you have more than one domain.
Domains List
The area on the left side of this dialog contains the list of your domains, with links to each screen used for configuring the various domain-specific settings. The
Default Domain is listed first and all other domains are listed alphabetically. The list on the right is used for deleting and renaming domains, and for designating the
Default Domain. You can double-click a domain in this list to switch to the domain and configure its settings.
Domain Management
New domain
To create a new domain: click New domain, enter the domain name in the Create/
Update Domain dialog, and click OK.
Typically the value entered here will be the registered Internet domain name that a
DNS server resolves to the IP address of the local machine running the server, or a qualified alias of that name. Alternatively, you may choose to use an internal-only or otherwise non-valid, non-public domain name (such as "
company.mail
") for your domain name. When configuring your server in this way it may be necessary to use the
114
feature, and/or the
Domain Name Replacement Engine
128
, to enable proper mail distribution.
Delete domain
To delete a domain: select the domain from the list below, click Delete domain, and then confirm your decision to delete the domain by clicking Yes.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

You cannot delete or rename the default domain. If you wish to delete or rename it then you must first designate a different domain as the default domain.
Rename domain
To change a domain name: select a domain from the list below, click Rename
domain, type the new domain name in the Create/Update Domain dialog, and click
OK.

Host Name & IP
Disable this domain (Cloud only)
Click this checkbox if you wish to disable the domain. Disabled domains are treated by MDaemon as if they do not exist. Domain users will not be able to send or receive mail and MDaemon will not accept incoming mail for the domain. This option is only available in MDaemon Private Cloud.
SMTP host name
This value is the Fully Qualified Domain Name (FQDN) that will be used in the
SMTP
HELO/EHLO
instruction when sending mail for this domain. For incoming connections, if the This domain recognizes only connections made to the host IP address option below is used, the domain is bound to its own IP address and the proper FQDN will be used for connections made to that domain. Using that option, however, is not strictly required for this to work. But, if you have two or more domains using the same unbound IP address then the FQDN used will be the one that is associated with the domain that is first in alphabetical order.
In most cases the FQDN will be either the Domain name or a subdomain of it (for example, “
mail.example.com
”), but an IP literal syntax such as “
[192.0.2.0]
” may also be used. When no FQDN value is specified, MDaemon will use the Default
Domain’s FQDN.
IPv4/IPv6 address
Enter the IPv4 and IPv6 addresses to associate with this domain. If an IP address is missing MDaemon will automatically try to detect a suitable address for use.
Detect
Use these buttons to detect the IPv4 and IPv6 IP addresses that are eligible for use in the corresponding IP address options. You can then choose from the IP addresses listed.
This domain recognizes only connections made to these IPs
Click this checkbox if you wish to restrict this domain's incoming connections to the

Use SMTP authentication
Click this check box and enter your login credentials below if the Smart Host requires authentication. These login credentials will be used for all outbound SMTP messages sent to the smart host. If, however, you choose to use the Allow per-
account authentication option below, then MDaemon will authenticate to the host separately for each message, using the sending account’s Smart Host Access credentials designated on the
605
screen of the Account Editor.
User name
Enter your user name or login here.
Password
Use this option to specify your smart host login password.
Allow per-account authentication
Click this checkbox if you wish to use per-account authentication for outbound
SMTP messages sent to the Smart Host specified above. Instead of using the User
name and Password credentials provided here, each account’s Smart Host Access credentials, designated on the
605
screen, will be used instead. If no smart host credentials have been designated for a given account, the above credentials will be used instead.
If you wish to configure per-account authentication to use each account’s Email
password instead of its optional Smart host password, then you can do so by editing the following key in the
MDaemon.ini
file:
[AUTH]
ISPAUTHUsePasswords=Yes (default No)
Enabling the
ISPAUTHUsePasswords=Yes
option will over time effectively communicate all your accounts’ local mail passwords to your smart host. This could pose a risk to mail security, since it is providing sensitive information to another server. You should not use this option unless you are using a smart host that you absolutely trust and you believe it is necessary to do so. Further, you should note that if you use this option and give your users permission to change their
Email password via WorldClient or some other means, then changing the Email password will also effectively change the
Smart host password. This could cause smart host authentication to fail for an account when its Email password is changed locally but the corresponding Smart host password isn't changed at your smart host.

Validate/correct PIM mrk file integrity
This option runs a validation and correction process on the client's PIM data to look for known issues that could prevent it from syncing correctly, such as duplicate iCal
UIDs or empty required fields. The global option is disabled by default.
Options
Create Tasks/Reminders for flagged mail items
This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.
Allow search operations on...
Public Folders
Allows the client to search the
251
to which it has access. This is allowed by default.
Shared Folders
Allows the client to search the
629
to which it has access. This is allowed by default.
Send server based read receipts when requested.
Enable this option if you want the server to support read confirmation requests and issue a read receipt when a message is flagged as read by a client. This is disabled by default.
Request read receipts for all mail sent
Enable this option if you want the server to request read confirmation for all mail sent by a client. This is disabled by default.
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway, MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
176 MDaemon Messaging Server 17.0
in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.
New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.
Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e.
the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 177
be included. This option is disabled by default.
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

Password Type
Simple PIN
How this option is implemented is largely dependent on the device, but selecting Simple PIN as the password type generally means that no restrictions or complexity requirements are placed on the device password, other than the
Minimum password length option below. This allows simple passwords such as:
"111," "aaa," "1234," "ABCD" and the like.
Complex/Alpha-Numeric
Use this policy option if you wish to require more complex and secure device passwords than the Simple PIN option. Use the Complexity level option below to define exactly how complex the password must be. This is the default selection when a password is required by the policy.
Password Strength
Minimum length
Use this option to set the minimum number of characters that the device password must contain, from 1-16. This option is set to "1" by default.
Complexity level
Use this option to set the complexity level requirement for Complex/Alpha-
numeric device passwords. The level is the number of different types of characters that the password must contain: uppercase letters, lowercase letters, numbers, and non-alphanumeric characters (such as punctuation or special characters). You can require from 1-4 character types. For example, if this option were set to "2", then the password must contain at least two of the four character types: uppercase and numbers, uppercase and lowercase, numbers and symbols, and so on. This option is set to "1" by default.
Password Options
Days until password expires (0=never)
This is the number of days allowed before the device's password must be changed. This option is disabled by default (set to "0").
Number of recent passwords remembered/disallowed by device (0=none)
Use this option if you wish to prevent the device from reusing a specified number of old passwords. For example, if this option is set to "2" and you change your device password, you will not be able to change it to either of the last two passwords that were used. The option is disabled by default (set to
"0").
Minutes of inactivity before device locks (0=never)
This is the number of minutes that a device can go without any user input before it will lock itself. This password option is disabled by default (set to "0").

Removing an ActiveSync Device
To remove an ActiveSync device, select the device and click Remove. This will remove the device from the list and delete all synchronization information related to it in
MDaemon. Therefore if in the future the account uses ActiveSync to synchronize the same device, MDaemon will treat the device as if it had never before been used on the server; all device data will have to be re-synchronized with MDaemon.
Full Wiping an ActiveSync Client
To do a Full Wipe on an ActiveSync client or device, select the client from the list and click Wipe Client and then Wipe Client (Factory reset). The next time the client connects, MDaemon will tell it to erase all data, or restore itself to its factory default state. Depending on the client, this may remove everything on it, including downloaded apps. Further, as long as the client's ActiveSync entry exists in MDaemon, it will be wiped again if it ever connects again to MDaemon in the future. If you no longer wish to wipe the client when it connects (for example, if a lost device is recovered and you wish to use it again with the account) then you must first use the Remove option above to remove the client from MDaemon.
Account Wiping an ActiveSync Client
To wipe the account's mail and PIM data from the client or device, click Wipe Client and then Account Wipe (Account's Mail and PIM data only). The Account Wipe option is similar to the Full Wipe option explained above, but instead of wiping all data, it will wipe only the account's data, such as its emails, calendar entries, contacts, and the like. The rest, such as apps, photos or music is left alone.

This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.
Allow search operations on...
Public Folders
Allows the client to search the
251

Shared Folders
Allows the client to search the
629
to which it has access. This is allowed by default.
Send server based read receipts when requested.
Enable this option if you want the server to support read confirmation requests and issue a read receipt when a message is flagged as read by a client. This is disabled by default.
Request read receipts for all mail sent
Enable this option if you want the server to request read confirmation for all mail sent by a client. This is disabled by default.
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway,
MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.

New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.
Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e. the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will be included. This option is disabled by default.
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 193
default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

4.3 Gateway Manager
The Gateway Manager is an MDaemon PRO feature and is reached from the S etup »
Gateway M anag er. . .
menu selection. This feature provides a limited yet useful secondary level of support for hosting multiple domains or acting as a backup mail server for someone.
For example:
Suppose you wish to act as a backup server or mail-drop for a third party, receiving its incoming email and storing it in a folder on your server, but you do not wish to host its domain fully, maintaining its individual user accounts. Let
' s use
"example
.com
" as its name.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
194 MDaemon Messaging Server 17.0
The first thing you will do is create the gateway by clicking New gateway on the
Gateway Manager and then entering " example.com
" as its name. Now all mail that
MDaemon receives for that domain will be separated from the main mail stream and placed in the folder designated on the gateway's
201
screen, regardless of the specific individuals to which each message is addressed.
Next, you will designate the collection or delivery methods that you wish to allow or use to get the domain's email to its actual email server, where its user accounts are hosted. There are two ways to do this: use the Deliver stored messages each time
MDaemon processes remote mail option on the
201
, or use the
207
options. Optionally, you can also create an MDaemon account and change its
604
to the
201
that your gateway uses.
This will allow a mail client to connect to MDaemon to collect example.com's email.
Finally, you will likely have to edit the DNS settings for example.com so that your
MDaemon server is a designated MX host for that domain.
There are many other features and options available, but the above example is the basic form that a typical gateway will take. If, however, you require an atypical configuration then you may have to do some things differently, such as when you wish to use a domain name that doesn't actually exist on the Internet, like "company.mail."
Receiving messages for an otherwise invalid domain name such as that is possible, but the domain name must be "hidden" inside a
152
address. Using that method, addresses can be constructed that will pass through the default domain and on to the gateway. For example, if your default domain is example.com and you have a gateway for company.mail, then someone could send a message to
" by using the address, " bob{company.mail}@example.com
." Since
" example.com
" is the registered domain hosted by MDaemon, this message would be delivered properly, but when MDaemon received the message in that format it would convert the address to " [email protected]
" and deliver the message to the folder specified for that gateway. Of course the simplest method is still to register a valid domain name for the gateway and then point its DNS or MX record to example.com.

New gateway
To create a new gateway: click New gateway, enter the gateway name (e.g.
example.mail) in the Create/Rename Gateway Domain dialog, and click OK.
Typically the value entered here will be the registered Internet domain name that a
DNS server resolves to the IP address of the local machine running the server, or a qualified alias of that name. Alternatively, you may choose to use an internal-only or otherwise non-valid, non-public domain name (such as "
company.mail
") for your gateway name. This, however, would require you to use the nested domain name method outlined in the example above, or require you to utilize some other content filtering scheme to get the messages where they belong.

The Gateway Editor is used for editing each gateway's settings. It includes the following screens:
201
Use this screen to enable/disable the gateway, designate the folder used for storing the domain's messages, and configure other delivery and attachment-handling options.
202
If the remote domain’s server is configured to keep an LDAP or Active Directory server up to date with all of its mailboxes, aliases, and mailing lists, or if it runs a
Minger server to provide remote address verification, you can use this dialog to specify that server and thus verify the validity of recipient addresses of incoming messages. When a recipient address is found to be invalid the message will be rejected. With this method you can avoid having to assume that all recipients of a domain’s messages are valid.
206
With this screen you can declare a host or address to which the domain
' s mail will be forwarded as soon as it arrives. There are also options for stating whether a copy of these messages should be kept locally and for designating the port on which the forwarded messages should be sent.
207
Using the options on this screen, you can configure MDaemon to respond to ETRN and ATRN requests made on behalf of the domain in order to dequeue its messages.
You can also configure several other dequeuing related options.
210
This dialog is used for assigning a limit to the amount of disk space that the domain may use and the maximum number of messages that may be stored.
211
This screen contains a number of other options that will apply to the selected domain gateway. For example, you can enable/disable AntiVirus and AntiSpam scanning for the gateway, designate whether or not authentication is required when dequeuing mail, designate an authentication password, and several other options.

4.3.2 Automatic Gateway Creation
Setup Menu 199
Automatic Gateway Creation (MDaemon PRO only)
This feature is used to automatically create a Domain Gateway
193
for a previously unknown domain when another source attempts to deliver that domain
' s messages to
MDaemon, and a DNS query lists MDaemon
' s location as a valid MX record.
For example:
With automatic gateway creation enabled, if MDaemon
' s Default Domain IP address is
192.0.2.0
and a message is delivered via SMTP for an unknown domain example.com
,
MDaemon will perform MX and A-record queries on example.com
to see if
192.0.2.0
is a known mail relay host for it. If the results of the DNS queries state that MDaemon
' s
IP address is a valid MX host for example.com
then MDaemon will automatically create a new Domain Gateway for it and accept its email. Messages for example.com
will then be stored in a special folder and, if you so choose, spooled to higher level MX hosts at each remote mail processing interval. This feature effectively enables you to become a backup server for another domain by simply configuring the DNS system to use your IP as an alternate MX host.
To help secure this feature, MDaemon can be configured to send a confirmation request to an email address of your choice. While MDaemon is waiting for the confirmation response, messages for the domain will be accepted and stored but not delivered. Confirmation requests must be replied to within an amount of time that you
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
200 MDaemon Messaging Server 17.0
designate or the automatically created gateway will be removed and all stored messages deleted. If confirmation is received before the time has expired then the stored messages will be delivered normally.
It might be possible for a malicious person or "spammer" to attempt to exploit this feature by configuring their DNS server to list your MDaemon's IP address as one of their MX hosts.
Automatic Gateway Creation must therefore be used with caution. To aid in preventing possible exploitation we recommend utilizing the Send creation confirmation message to... feature whenever possible.
Automatically create gateway domains

Deliver stored messages each time MDaemon processes remote mail
Ordinarily, when MDaemon receives mail that is intended for one of its gateways, it will store the mail until that domain connects to MDaemon to collect it. In some situations you may want MDaemon to attempt to deliver the mail directly via SMTP rather than waiting for the domain to collect it. When this option is enabled,
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
202 MDaemon Messaging Server 17.0
MDaemon will attempt to deliver the domain
' s messages each time remote mail is processed. The gateway
' s mailbox will temporarily act as a remote queue and delivery will be attempted. Any messages that cannot be delivered will simply remain in the gateway
' s mailbox until they are collected by the domain or are successfully delivered later; they will not be moved into the remote queue or retry system.
However, if you do not have the domain's DNS properly configured, or if you have your MDaemon configured to pass all outgoing messages to some other host for delivery, then you could cause those message to get caught in a mail loop and then eventually be treated as undeliverable.
Automatically extract embedded attachments
Some mail systems require attached files be extracted before submission of mail messages to the mail stream. To facilitate this, MDaemon can auto-extract incoming
MIME attachments and place them in the
\Files\
subfolder underneath the domain
' s message folder. Check this box if you wish to automatically extract attachments.
4.3.3.2 Verification
One common problem with domain gateways and mail-drops is that they don't usually have a method for determining whether or not the recipient of an incoming message is valid. For instance, if you act as a gateway for example.com and a message comes
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 203
for
[email protected]
then you have no way of knowing whether or not there is actually a mailbox, alias, or mailing list corresponding to that address on example.com's email server. Thus you have no choice but to assume that the address is valid and accept the message. Further, since spammers commonly send messages to many invalid addresses, this problem can result in large amounts of junk email being accepted for the gateway.
MDaemon contains a method to prevent this by verifying the recipient addresses. If the remote domain's server is configured to keep an LDAP or Active Directory server up to date with all of its mailboxes, aliases, and mailing lists, or if it runs a Minger server to provide remote address verification, then you can use the options on this screen to specify the LDAP, Active Directory, or Minger server where this information is stored.
Then, when a message arrives for
example.com
, you can lookup the recipient's address on the other server and discover whether or not it is valid.
Address Verification
Verify addresses using:
Nothing
Choose this option if you do not wish to use email address verification for this domain gateway. MDaemon will treat all of the domain's incoming messages as if the recipient is a valid address, since it will have no way of identifying which addresses actually exist for that domain.
File
Choose this option if you wish to use the
GatewayUsers.dat
file as the definitive list of addresses that will be used to verify whether or not the recipient of an incoming message for this domain is valid. This is a global list of addresses, applicable to all of your domain gateways, and even if you have chosen to use one of the other verification methods, this list will still be used as an extra source of valid addresses. When using the File option, however, it will be the only verification option used. You can open and edit the valid address list by clicking the Address verification file button below.
LDAP
Choose this option to activate remote address verification via LDAP or Active
Directory. Whenever a message arrives for the remote domain its LDAP or Active
Directory server will be queried to determine whether or not the recipient is valid.
If it isn't valid the message will be rejected. If MDaemon is unable to connect to the LDAP/AD server then it will assume the address is valid.
Minger
Choose this option if you wish to query the domain's Minger server to verify recipient addresses for this domain. If MDaemon is unable to connect to the server then it will assume the address is valid. There is also a global option located on
197
that you can use to cause MDaemon to query your
108
hosts as well.
Host name or IP
Enter the host name or IP address of the domain's LDAP/Active Directory or Minger server. This is the LDAP/AD or Minger server to which MDaemon will connect in order
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

to verify that the recipient of an incoming message is a valid address at the domain for which this MDaemon is acting as a gateway or backup server.
Port
Specify the port that the domain's LDAP/AD or Minger server is using. MDaemon will use this port when verifying address information via LDAP, Active Directory, or
Minger.
Test
Click this button to test whether or not you have the remote address verification settings configured properly. MDaemon will simply attempt to connect to the designated LDAP/AD server and verify that it responds to the specified information.

Server is protocol version 3
Click this checkbox if want gateway verification to use LDAP protocol version 3 with your server.
Chase referrals
Sometimes an LDAP server doesn't have a requested object but may have a crossreference to its location, to which it can refer the client. If you want gateway verificaiton to chase (i.e. follow) these referrals, enable this option. This is disabled by default.
User name or Bind DN
Enter the User name or DN of the account that has administrative access to the domain's LDAP/AD server so that MDaemon can verify the recipients of incoming messages addressed to the domain for which it is acting as a gateway or backup server. This is the DN used for authentication in the bind operation.
Password or Minger shared secret
This password will be passed to the domain's LDAP/AD server along with the Bind DN value for authentication. If using a Minger server then this is the shared secret or password used.
Base entry DN
This is the Distinguished Name (DN) or starting point in the Directory Information
Tree (DIT) at which MDaemon will query your LDAP/AD server for address verification.
Search filter
This is the LDAP/AD search filter that will be used when querying your server to verify addresses. MDaemon will setup a default search filter that should work in most cases.
Search scope:
This is the scope or extent of your LDAP/AD searches.

Use this option if you wish to extend your LDAP/AD search to one level below the supplied DN in your DIT.
Base DN and all children
This option will extend the scope of your search from the supplied DN to all of its children, down to the lowest child entry in your DIT.
Address verification file
Click this button to open the Gateway Valid Email Address List (i.e. the
GatewayUsers.dat
file). This contains a list of addresses that MDaemon will consider to be valid recipients for incoming messages addressed to your domain gateways. Regardless of the verification option selected above, MDaemon will use this list as an extra source of valid address data. When using the File option above, however, it will be the definitive and only verification option used.
Using multiple configurations for LDAP verification queries
You can specify multiple LDAP configurations for your gateway domains. To specify extra sets of LDAP parameters, setup your first set normally and then manually edit the
GATEWAYS.DAT
file using Notepad.
Your new set of parameters should be created using the following format:
LDAPHost1=<host name>
LDAPPort1=<port>
LDAPBaseEntry1=<base entry DN>
LDAPRootDN1=<root DN>
LDAPObjectClass1=USER
LDAPRootPass1=<password>
LDAPMailAttribute1=mail
For each new set of parameters, increase the numeral in each parameter
' s name by 1.
For example, in the sample set above, each parameter's name ends with "1". To create an additional set each name would end with "2". In another set, each would end "3", and so on.
When the LDAP queries take place, MDaemon will perform multiple LDAP queries in sequence to find a match. If an error or a match is found no further checks are performed.

4.3.3.4 Dequeuing
ETRN
This gateway honors ETRN requests
When this switch is enabled MDaemon will respond to ETRN requests made by qualified hosts on behalf of the domain for which MDaemon is acting as an email gateway. The ETRN command is an SMTP extension that signals a server storing mail
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
208 MDaemon Messaging Server 17.0
for a particular domain that it is time to begin spooling the mail. When MDaemon receives an ETRN request for a domain, it will immediately begin spooling the stored mail for delivery using subsequent SMTP transactions. Please note that the SMTP session that issues an ETRN request will not be the one that receives any stored mail. MDaemon will use subsequent independent SMTP transactions to send any mail it has stored for the domain. This preserves the message envelope and is more secure. Also note that the host to which MDaemon will spool any stored mail may not immediately begin reception of these messages. ETRN only guarantees that any stored mail is
spooled
for delivery. The actual
process
of delivery is subject to other administrator-imposed restrictions and may have to wait in the outbound mail queue for the next scheduled remote mail processing event to take place. Because of these limitations we recommend using
100
and its
ATRN command rather than ETRN. This method is not supported by all clients and servers, however, and will therefore only be available to client domains using a server that does so. MDaemon fully supports ODMR on both the client and server side.
By default MDaemon requires that the connecting host issuing the ETRN request first authenticate itself via ESMTP AUTH using the
201
and
211
as its login credentials. If you do not wish to require authentication than you can disable it on
211
by clearing ETRN dequeuing requires authentication.
When an ETRN request is received:
...deliver stored mail to the IP of the host making the request
Selecting this option will cause MDaemon to send any stored mail to the IP address of the machine that made the ETRN request. The requesting machine must be running an SMTP server to receive these messages.
...deliver stored mail to this domain
This is the host name, domain name, or IP address to which any stored mail will be sent when an ETRN request is received and honored. The receiving machine must be running an SMTP server to receive these messages. Note: when a domain name is specified in this option, A and MX records may be used, depending on the DNS results during delivery. If you wish to deliver the messages to a particular host then place the host name in brackets (for example,
[host1.example.net]
) or specify an IP address instead of a domain name.
If the domain listed above is local treat it as if it were foreign
Activate this control if the domain is local but you want its mail to be spooled as if it is remote.
Deliver mail using this TCP port
Use this box to specify the port on which the domain
' s mail will be spooled.

ATRN
This gateway honors ATRN requests
Enable this option if you want MDaemon to respond to
ATRN
commands from the gateway's domain.
ATRN
is an ESMTP command used in
100
, which is currently the best relay method available for mail hosting. It is superior to ETRN and other methods in that in requires authentication before mail is dequeued and does not require a static IP address. A static IP address isn't required because the flow of data between MDaemon and the client domain is immediately reversed and the messages are de-spooled without having to make a new connection, unlike
ETRN
, which uses a separate connection after the
ETRN
command is sent. This enables client domains with a dynamic (non-static) IP address to collect their messages without having to use POP3 or DomainPOP, because the original SMTP envelope is preserved.
ATRN requires a session using the AUTH command. You can configure the authentication credentials on the
211 screen.
Allow only one ATRN session at a time
Click this check box if you wish to restrict ATRN to one session at a time.

Apply message and disk space quotas to this gateway
Enable this option if you wish to designate a maximum number of messages allowed to be stored for the domain or a maximum amount of disk space (in kilobytes) that it can use. This includes any decoded file attachments in its Files directory. When a quota is reached, any further incoming messages addressed to the domain will be refused.

ETRN dequeuing requires authentication
When you configure the settings on the Dequeuing tab to accept ESMTP ETRN requests, this option will be used by default to require the connecting host to first authenticate using the ESMTP AUTH command. When this option is enabled, you must designate an authentication password in the "Auth password" box provided below.
Clear this checkbox if you do not wish to require authentication of hosts making
ETRN requests.
Authenticated requests are valid regardless of connecting IP
Enable this checkbox if you wish to honor authenticated requests regardless of the
IP address from which they are coming. If this control is not enabled then only requests from those IP addresses specified in the Access section will be honored.
Authenticated is required when sending mail as a user of this gateway
Click this check box if you want all messages claiming to be from this domain to require authentication. If a message is purported to be from this domain then it must be using an authenticated connection (or connecting from a Trusted IP address) or it will be refused. This option is enabled by default.
When new domain gateways are created, this option will be enabled by default. If you wish to change the default setting so that new gateways will have this option disabled, then edit the following key in the
MDaemon.ini
file:
[Special]
GatewaySendersMustAuth=No
(default is Yes)
Gateway AUTH password
When using ATRN to dequeue this gateway
' s mail, or when you are requiring authentication via the
ETRN dequeuing requires authentication
option above, designate the gateway
' s AUTH password here.
The domain for which MDaemon is acting as an email gateway must use its domain name as the logon parameter. For example, if the domain gateway is "example.com" and is using
ATRN to dequeue its mail, then it would authenticate using the login credentials "example.com" and the password specified here.

Honor '<List>-subscribe' and '<List>-unsubscribe' addresses
Click this checkbox if you want MDaemon to recognize email addresses of this format as valid (as long as the list actually exists) in order to facilitate an easier method for users to join and leave your mailing lists. For example: suppose you have a list called
[email protected]
. People will be able to subscribe/unsubscribe to your list by sending an email message to
[email protected]
and
[email protected]
. The content of the subject and message body is irrelevant. Also, when this feature is active MDaemon will insert the following header into all list messages:
List-Unsubscribe: <mailto:<List>[email protected]>
Some mail clients can pick up on this and make an UNSUBSCRIBE button available to users automatically.
You can override this option for individual lists by specifying a value for the List-Subscribe and List-Unsubscribe headers in the Mailing List URLs options located on the Mailing List
Editor's
235
screen.
Add 'Sender: <List>' header to all list messages
Enable this option if you wish to insert the
Sender
header into mailing list messages.
Mailing list pruner deletes messages that it can't parse
When this option is enabled, MDaemon will delete list messages that do not contain a parsable address.
Mailing list pruner saves messages that cause list member removal
When MDaemon scans returned list messages in an attempt to remove member addresses that cannot be reached, this control will cause messages that result in a list member
' s removal to be saved. For more information, see the
Remove undeliverable email addresses...
option on the
221
screen.
Screen incoming mailing list mail for obvious non-list content
Check this box if you wish MDaemon to reject messages addressed to a mailing list when it determines that they should have been addressed to the system account instead. For example, a user may join or leave a list by placing the Subscribe or
Unsubscribe command at the beginning of an email message and sending that
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 217
message to the system address (e.g. "[email protected]"). Oftentimes users erroneously try to send those sorts of messages to the list itself. This option will prevent those messages from being posted to the list.
Do not send copy of list message to sender of message
When this option is enabled and a list member sends a message to the list, the sender will not receive a copy of the message. This option is disabled by default.
Remove duplicate list recipients when single message submitted to multiple lists
When this option is enabled and a single message is addressed to multiple mailing lists, MDaemon will deliver only one copy of the message to any recipient who is a
218
of more than one of the lists. For example, if [email protected] is a member of [email protected] and [email protected] and an incoming message is addressed to both lists, Frank will receive only one copy of the message rather than two. This option only applies to lists, therefore in the above example if the message were addressed to Frank directly, plus the two lists, then Frank would receive two copies of the message rather than three. This option is disabled by default.
Using this option is not generally recommended. Mailing lists can be used and organized many different ways by users, and there is no way of knowing which list will receive the message when limiting duplicates in this way. Therefore using this option could cause unnecessary difficulties for some users, due to message threading preferences, using
623
to sort messages to specific folders, and so on.
Add the following custom 'Header: value' to all list messages
If you wish to add a static header/value combination (such as "Precedence: bulk") to all list messages, specify that text here.
Digest 'Subject:' text:
Use this option if you wish to customize the subject used when MDaemon sends
231
messages. The default is: "$LISTNAME$ message digest
$TIMESTAMP$ $ISSUE$.
" The macros expand to the name of the mailing list, the time-stamp of the digest message creation, and the issue number.
Maximum members per mailing list [xx] (0=no limit)
Use this option if you wish to set a maximum number of members allowed per mailing list. You can set a per domain maximum on the Domain Manager's
screen. This option is only available in MDaemon Private Cloud.

Enhanced List Pruning
When the Remove undeliverable email addresses from list membership option is enabled and you have specified a local mailbox as the return path for the list's messages (see the List's SMTP 'Bounce' address option on
233
), each day at midnight MDaemon will attempt to parse problem addresses from the returned mail and remove those members that couldn't be reached. This will aid in more efficiently pruning invalid addresses from mailing lists, especially when you are routing the list's messages to a smart host rather than delivering them directly.
On
M ai li ng L i s t S etti ng s
215
there are two options related to this feature. The Mailing
list pruner deletes messages that it can't parse option will cause returned messages that do not contain a parsable address to be deleted, and the Mailing list pruner saves
messages that cause list member removal option will cause all messages that result in a list member being deleted to be saved.
Setting the
233
to a local user's address could cause that user's email to be deleted as a result of the list pruner settings designated on
215
.
When delivery to an address results in a 5xx error, the address will be appended to the BadAddress.txt file located in the logs folder. This can help you, for example, identify bad addresses in your mailing lists more quickly than searching the outgoing SMTP logs. This file is automatically removed at midnight each night to prevent it from growing too large.

Use this option to designate the text to display in the name portion of the TO: header whenever MDaemon receives a message directed to the list.
Nothing (make no changes) -
When this options is selected MDaemon will make no changes. The display name and address contained in the TO: header will appear exactly as the sender of the message entered them.
List's name -
This option replaces the displayed name with the name of the list plus "List Member". For example, for a mailing list named "My-Family" the display name portion of the To: header would say, "My-Family List Member".

Replace 'Reply-To:' header email address with
This option is for designating the email address that will appear in each list message's Reply-To: header.
Nothing (make no changes)
Choose this option if you wish to leave the Reply-To: header unchanged from whatever it is in the original message that will be distributed to the list. This is generally the option you should choose when you want replies to be directed back to whomever posted the message to the list, rather than to all of the list's members.
List's email address
Choose this option if you want replies to be directed to the list rather than to a specific person or address. This is the option you should choose if you wish to use the list as a group discussion tool, where replies are sent to all members.
This email address
If there is a specific email address to which you wish replies to be sent then type it here, or click the Account icon if you wish to browse for a specific
MDaemon account to use. You could use this option, for example, for something like an email newsletter with a specific contact address for replies.
Replace 'From:' email address with list's email address if message is sent from a domain that publishes restrictive DMARC policy
By default, when an incoming message to the list is sent from a user at a domain that publishes a restrictive
527
policy (i.e. p=quarantine or p=reject),
MDaemon will replace the user's email address in the From: header with the address of the list, before sending the message to the list. This is necessary to prevent the list message from being rejected by servers that honor restrictive DMARC policies. In addition to changing the From: header's email address, the displayed name will also be modified to add "via List Name," to show that it is a message sent by that mailing list on behalf of the named person. Further, any time the From: header is changed by this feature the original From: header data will be moved into the Reply-To: header, but only if the message has no Reply-To: header to begin with and the list isn't configured to display a custom Reply-To: header.
You should not disable this option unless you fully understand the ramifications of doing so and are certain that you need to disable it. Disabling this option would likely cause some list messages to be rejected by some receiving servers, and in some cases it could cause the recipient to be
automatically removed from list membership
223
. Alternatively, you could
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

enable the
Refuse messages from domains with restrictive
221
option instead, which causes incoming messages to the list to be refused when coming from a domain with a restrictive DMARC policy.
Prepend 'Subject:' header text with name of list
This setting causes MDaemon to enclose the name of the list in brackets (e.g.
[ListName]) and add it to the beginning of the
Subject:
in all messages sent to the list. This is enabled by default.
Append 'Subject:' header text with thread number
This switch allows you to toggle whether thread numbers will be displayed in the
Subject:
header of list messages. They are appended to the end of the subject line in braces and used as a pseudo thread number. Sorting your Inbox by subject will align list mail in chronological order. This option is disabled by default.

.
Confirm unsubscription requests
When this box is checked, MDaemon will attempt to confirm requests to remove a member from the list, by generating a unique code and then sending it in a message to the address requesting to unsubscribe from the list. If the person then replies to that confirmation message, MDaemon will automatically remove the member from the list. Confirmation messages are time-sensitive, meaning that the user must reply to the message within the number of minutes designated below.
Confirm autoresponder generated unsubscription requests
When this box is checked, MDaemon will attempt to confirm unsubscription requests that are generating automatically via the
611
option,
"Remove sender from this mailing list." As with the Confirm unsubscription
requests option above, MDaemon will generate a unique code and then send it in a message to the address waiting to be removed from the list. If the person then replies to that confirmation message, MDaemon will automatically remove the member. These confirmation messages are also time-sensitive and therefore must replied to within the number of minutes designated below.

Confirmations must be received within [XX] minutes
This is the number of minutes that the recipient of a subscription or unsubscription confirmation message has before the message will expire. If this time limit is exceeded before MDaemon receives a reply to the message, then the address will not be added or removed from the list. The address would then need to submit a new request to join or leave the list. The default setting of this option is 7200 minutes (i.e. five days).
This is a global value—it applies to all of your mailing lists rather than to the specific list you are editing.
Notify subscribers/unsubscribers on the status of their requests
When this checkbox is enabled, MDaemon will send a completion notification message to the user that has been subscribed/unsubscribed to the Mailing List.
Membership Limit
Limit this list's membership to [xx] members (0=no limit)
With this feature you can place an upper limit on the number of people who are allowed to subscribe to the Mailing List. Enter a zero into this field if you do not wish to limit list subscriptions.
This limit only applies to addresses subscribed via the email methods outlined in

4.4.2.4.1 Subscribing to Mailing Lists
Subscribing/Unsubscribing via Email Commands
To subscribe to or unsubscribe from a mailing list, send an email message addressed to
MDaemon
(or any alias thereof) at the domain hosting the mailing list, and place the
Subscribe
or
Unsubscribe
command as the first line of the message body. For example, there is a mailing list called
MD-Support
being hosted by
altn.com.
You can subscribe to the list by composing a message addressed to "
[email protected]
" and placing the value:
SUBSCRIBE [email protected]
as the first line of the message body. The message subject is irrelevant and can be left blank.
For complete details on how to form this and other control messages, see:
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 229
766
.
Occasionally, users will attempt to subscribe/unsubscribe to lists via email by sending the commands to the list itself rather than to the MDaemon system account. This results in the command being posted to the list rather than the user being subscribed or unsubscribed. To help prevent these sorts of messages from being posted to mailing lists, there is an option located at
S etup » Preferences » S ys tem
413
, called "Screen
incoming mailing list mail for obvious non-list content." This option is enabled by default.
Subscribing/Unsubscribing via Email Addresses
The option, "Honor '<List>-subscribe' and '<List>-unsubscribe' addresses," located at
S etup » M ai li ng L i s t M anag er » M ai li ng L i s t S etti ng s
215
, makes it possible for users to join or quit mailing lists by sending a message to a special email address rather than requiring them to use the email commands described in Subscribing/Unsubscribing via
Email Commands above. To use this method to join or quit a list, a user would simply send a message to the list's address, but with "-subscribe" or "-unsubscribe" appended to the mailbox portion of the address. For example, if the list's name is,
"[email protected]," then a user could subscribe to the list by sending a message to, "[email protected]." To unsubscribe from the list, the message would be sent to, "[email protected]." In both cases the content of the subject and message body is irrelevant. Also, when this feature is active MDaemon will insert the following header into all list messages:
List-Unsubscribe: <mailto:<List>[email protected]>
Some mail clients can pick up on this and make an UNSUBSCRIBE button available to users automatically.
Subscribing/Unsubscribing via Autoresponders
You can also utilize
611
to automatically add or remove list members. To do this you would create one or more MDaemon accounts whose sole purpose would typically be to automatically add or remove addresses who send messages to those accounts, via the Autoresponders configured for each account. For example, if you had a mailing list called, "[email protected]," then you could create an MDaemon account with the address: "[email protected]." You would then configure an autoresponder for that account to add to "[email protected]" any addresses sending messages to it. Then, to join that list, all someone would have to do is send an email to "[email protected]". This is a simple solution for users because it doesn't require them to remember any of the special email commands required by the Subscribing/Unsubscribing via Email Commands method outlined above.

4.4.2.5 Reminders
Subscription Reminders
Send monthly subscription reminders to all list members
Enable this option if you wish to send the contents of the provided text box as a subscription reminder message to each list member on the first day of each month.
The reminder message is sent as text/html so that you can use HTML code in the reminder text if you choose. The following macros are available for use within the reminder message:
$LISTADDRESS$ - expands to the mailing list's email address (e.g.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

$UNSUBADDRESS$ - expands the list's unsubscribe address (the MDaemon system address, e.g. [email protected])
$MEMBERADDRESS$ - expands to the email address of the list member receiving the reminder (e.g. [email protected])
If you wish to send reminders on a different day of the month, you can do so by setting the following key in the MDaemon.ini file:
[Special]
ListReminderDay=X
Set "X" to a number from 1 to 28, representing that day of the month you wish to send reminders.
4.4.2.6 Digest
Digest
Enable digest support for this mailing list
Check this box if you wish to allow digest support for this mailing list. When digest support is enabled, a copy of each message sent to the mailing list will be archived
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
232 MDaemon Messaging Server 17.0
so that list members who have their
218
set to Digest will periodically be sent batches of these archived messages in a compact and indexed format rather than receive them one at a time.
Force all list members to use digest mode
By default, list members can control whether they wish to receive list traffic in digest or normal format. Check this box if you wish to force all members to use digest mode, regardless of the mode they may have chosen for themselves.
Archive digests into a file catalog / which catalog do you want to use?
These options allow you to place digest messages into a file catalog so that backissues of the digests can be collected in the future. MDaemon will generate a unique archive name for each digest and place it into the catalog you specify.
For complete information on how to work with catalogs see:
738
.
When to send digests?
The following options determine how often and under what circumstances digests will be sent to those list members who are set to receive mail in digest format. All of the options operate independently of each other, meaning that any or all of them can cause a digest to be sent.
Send digest mail at 9, 12, 3, 6 AM, PM
Use this option to schedule how often this list's digests will be sent. If you check all of the boxes in this option then digests will be sent every three hours, in addition to any that may be triggered by the options below.
Spool digest mail if [xx] messages have accumulated (0 = n/a)
If you wish to send digests automatically whenever a certain number of messages have accumulated, specify that number here. Use "0" if you do not wish to use this option. "0" is the default setting.

Returned Mail
List's SMTP 'Bounce' address
Use this option to specify the address that should receive any "bounced" mail or deliver status notification messages generated from list traffic. Any given message to a mailing list with 100 recipients might have, for example, ten undeliverable addresses due to address changes, down servers, or the like. The SMTP system will generate and return to the sender of the message a notification message concerning these undeliverable conditions. Using this option you can designate the address that should receive these messages for your mailing lists. You can also choose for no one to receive them, in which case MDaemon will place list mail into the mail stream in such a way that return mail will not be possible. This address should NOT be the mailing list's address.
Setting the List's SMTP 'Bounce' address to a local user's address could cause that user's email to be deleted as a result of the list pruner settings designated on

Mailing List URLs (see RFC 2369)
MDaemon can add to mailing list messages any of the six header fields outlined in
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
236 MDaemon Messaging Server 17.0
RFC 2369:
The Use of URLs as Meta-Syntax for Core Mail List Commands and their
Transport through Message Header Fields
. The six headers are: List-Help, List-
Subscribe, List-Unsubscribe, List-Post, List-Owner, and List-Archive. If you wish to use any of these headers to the list's messages, enter the desired header value into any of the fields below. The header values must be formatted according to the RFC 2369 specification (for example, <mailto:[email protected]?
subject=help>
). See the linked document for several examples of each header.
MDaemon makes no changes to this data, therefore if the data is improperly formed it won't achieve any results.
Description (used in List-ID: header)
Enter a short description of your mailing list here if you wish to add it to the List-
ID:
header included in messages that are sent to the list. The description and the list's identifier will be included in the header (e.g. List-ID: "Frank's personal mailing list" <MyList.example.com>
) Note that the list's identifier is the mailing list's address with "." substituted for "@" in order to comply with the List-ID specification . If you leave the Description option blank then the List-ID: header will contain only the list identifier (e.g. List-ID: <MyList.example.com>). If an incoming message addressed to the list has a preexisting List-ID: header, MDaemon will replace the old header with the appropriate one for the list.
The List-Subscribe and List-Unsubscribe headers are included by default in all mailing list messages when the "Honor '<List>-
subscribe' and '<List>-unsubscribe' addresses" option is enabled on the
422
screen. If you wish to override that option for this list, using different header values than those added automatically by that option, enter the desired values here. If that option is disabled then no List-
Subscribe and List-Unsubscribe headers will be added to list messages unless you specify a value for them here.

4.4.2.9 Routing
Setup Menu 237
Routing
Deliver list mail to each member individually
If selected, when messages are received for distribution to the list, a separate copy of each message will be created and dispatched to each list member. This will result in numerous individual messages being created which could affect the server
' s performance, depending on the size of the list and the load on the server.
Replace Message-ID with unique value for each member
When MDaemon is set to generate a separate copy of each message for each member, click this checkbox if wish each of those messages to have a unique
Message-ID. This option is disabled by default and is not recommended unless you have special circumstances that require it.
Deliver list mail using individual RCPT commands for each member
If selected, MDaemon will route a single copy of each list message to the specified smart host, rather then send individual messages to each member. This method employs multiple RCPT To statements during the SMTP session with the specified host.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
238 MDaemon Messaging Server 17.0
Deliver to this host
Designate the smart host to which you wish to pass all of the list's messages for delivery, using RCPT To statements for each member.
Limit RCPTs to [xx] per message (0=no limit)
Some hosts limit the number of RCPT To statements that they will accept when you are attempting to route a single copy of a message through them. If you specify the limit in this control then MDaemon will work around it by creating additional copies of the message and dividing the list into smaller groups. Then it will deliver the message to those groups thus avoiding the need to exceed the limitation. This is similar to the Deliver list mail to each member individually option above, but it generates less copies, sending each copy to groups of addresses rather than generating a separate copy for each member.
Ignore RCPT errors when sending to host
Since some smart hosts will refuse to queue or spool mail for certain domains, the routed approach to list delivery could cause numerous problems. An error code returned from the smart host as a result of this refusal would ordinarily cause MDaemon to abort the delivery attempt. Check this option if you want
MDaemon to ignore error codes returned from the smart host during delivery of routed list mail, thus allowing those members that are accepted a chance to receive the message.

Designating a more precise starting point closer to the location of your user accounts or desired group of addresses in your particular Active Directory tree can reduce the amount of time required to search the DIT. Leave this field blank if you do not wish to pull any list addresses from Active Directory.
Search filter
This is the LDAP search filter that will be used when for searching Active Directory.
Use this filter to enable MDaemon to more precisely locate the desired user accounts or addresses that you wish to treat as list members.

It will not, however, delete any other user or group permissions that currently have access to those folders.
Example,
The parent folder grants certain permissions to User_A and User_B. The child folder grants permissions to User_B and User_C. This option will add User_A permissions to the child folder, replace the child folder's User_B permissions with those from the parent folder, and do nothing to the User_C permissions. Therefore the child folder will then have User_A, User_B, and User_C permissions.

Access rights are controlled through MDaemon's support for
Access Control Lists (ACL). ACL is an extension to the Internet
Message Access Protocol (IMAP4), which makes it possible for you to create an access list for each of your IMAP message folders, thus granting folder access rights to other users who also have accounts on your mail server. If your email client doesn't support ACL you can still set the permissions via the controls on this dialog.
ACL is fully discussed in RFC 2086, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2086.txt

4.6 Web & IM Services
4.6.1 WorldClient (web mail)
4.6.1.1 Overview
WorldClient is a web-based email solution included in MDaemon and designed to offer users email client functionality using their favorite web browser. WorldClient can easily hold its own against traditional mail clients while providing the added bonus of its ability to enable users to access their email from anywhere at anytime as long as they have an Internet or network connection. Further, because all of their email folders, contacts, calendars, and so on reside on the server instead of on their local computer, they can have access to everything as if they were at their desk.
WorldClient provides many benefits to email administrators. Since WorldClient isn't workstation dependent you can configure everything from the server, unlike many client applications. This saves you from having to configure and maintain each individual email client. You can also customize the graphical images and HTML pages used in WorldClient to suit your corporate needs, or the needs of your customer.
Further, you can give your users the ability to maintain their own account settings thus saving you time — you can give as much or as little control to your users as you want.
Finally, in addition to the convenience of having a web-based client, there are many additional features that will benefit your users, such as: extensive email functionality, client-side interface available in almost 30 languages, personal and global address books, manageable mail folders and filters, send/receive file attachments, multiple visual "themes" for the interface, themes for mobile devices, calendar features, groupware features, an integrated instant messenger that can be downloaded to your desktop, and much more.

Setup Menu 259
Calendar & Scheduling System
MDaemon is equipped with a complete collaboration system. From within WorldClient you can easily create appointments, schedule meetings, and work with address books.
Recurring appointments are fully supported, and appointments have many fields available to describe them. Further, contacts, calendars, and task data are stored as
IMAP folders within each user
' s root mail directory. Through WorldClient, your users can access these personal folders and control which other users have access to them. All
WorldClient themes have templates that present contact, calendar, notes, and task folders in a logical and attractive way.
Because the Calendar system is integrated with MDaemon, there is the added benefit of email notifications of appointments, whether scheduled by you or a third-party.
Whenever someone other than yourself schedules an appointment for you, you will receive an email message summarizing the appointment. Each designated appointment attendee will receive an email message detailing the appointment
' s date, time, location, subject, and list of attendees. Further, any attendees who have calendar entries that conflict with the appointment
' s time slot will receive a message notifying them of the appointment and its conflict with their schedule. The person who scheduled the meeting will receive a summary message listing all of the meeting
' s details and invited attendees who did or did not have scheduling conflicts.
The Calendar System is also equipped with support for Internet Calendar (iCal) used by
Microsoft Outlook and other iCalendar compliant email programs. The Calendar System can detect and process iCalendar information sent to your users and update their calendars accordingly. When a user opens an iCalendar attachment from within
WorldClient the information contained in the attachment will be reflected in the user
' s
WorldClient calendar. Also, when users create new meetings or appointments they can list one or more email addresses to which they wish an iCalendar email to be sent. This feature can be set by individual users in their WorldClient options.
WorldClient Instant Messenger
WorldClient Instant Messenger (WCIM) is MDaemon
' s secure instant messaging client and tray applet that provides quick access to WorldClient
' s email features. WCIM can be downloaded by each WorldClient user and then installed on the individual
' s local computer. It is pre-configured for the specific user when downloaded, thus limiting the need to configure it manually.
WCIM runs in the background and checks your account for new mail by querying the
WorldClient server directly. This eliminates the need to open a browser or keep one open to check your email — WCIM checks for new mail and notifies you with a sound or visual alert when new mail arrives. WCIM also displays a list of your mail folders and the number and type of messages that each one contains (new, unread, and read).
Furthermore, it can be used to launch your browser and move it immediately to a specific mail folder.
WCIM is also equipped with a complete instant messaging client. You can view your list of WCIM contacts and each one
' s online status (online, away, offline), start a conversation with any one or group of them, set your own online status, and view past conversations in a history folder.
For specific instructions on how to use WorldClient Instant Messenger, see its online

help system.
WorldClient Instant Messenger's Instant Messaging System
WCIM is equipped with an instant messaging (IM) client that utilizes MDaemon's
306
server. Using this feature you can add other users who share your domain (and optionally other domains hosted on your MDaemon server) to your WCIM contacts list and then communicate with them instantly. You can set your online status, view the status of your contacts, use emoticons, set text color, send files, set notification sounds and control other preferences. You can also start a group conversation involving several contacts at once. The IM features are available via the tray icon's shortcut menu, and from the WCIM window.
WorldClient Instant Messenger's IM system is also scriptable, which allows custom programs to interface with it. By creating semaphore (
SEM
) files in the
\MDaemon
\WorldClient\
folder, an external application can send instant messages to your WCIM users. The following is the format of the SEM file:
From: [email protected]
<blank line>
Text of instant message.
Email address of WCIM user.
Email address of instant message's sender.
This is the text sent as an instant message.
The
SEM
file name must start with the characters "
IM-
" and be followed by a unique numerical value. For example, "
IM-0001.SEM
". Applications should also create a corresponding file called "
IM-0001.LCK
" to lock the
SEM
file. Once the
SEM
file is completed remove the
LCK
file and the
SEM
file will be processed. MDaemon uses this scripting method to send Instant Message reminders to you about upcoming appointments and meetings.
The Content Filter system is equipped with an Action that uses this scripting method to send instant messages. Further, rules utilizing this action can use the Content Filter macros in the IM. For example, you could create a rule to send an instant message rule containing lines like this:
You have received an email from $SENDER$.
Subject: $SUBJECT$
This rule would be an effective way to send new mail alerts through WCIM.
Because some administrators have reservations about using an Instant Messaging system in their company due to the inherent lack of centralized accountability and the inability to monitor IM traffic that is in traditional and well known IM clients, we have designed WCIM
' s instant messaging system to minimize those deficiencies. First of all, our system is not peer-to-peer — individual WCIM clients do not connect directly to each other for instant messaging. Further, because every instant message passes through the server, each message is logged in a central location accessible to the
MDaemon/WorldClient administrator. Thus a record of all conversations can be maintained for the security of both your company and your employees or users. IM activity is logged in a file called
XMPPServer-<date>.log
located in the
MDaemon
\LOGS\
directory.

Instant Messaging is provided on a per-domain basis. The global control for activating instant messaging is located on the
274
of the WorldClient dialog (S etup »
W eb & I M S erv i ces » W orldC li ent ( web mai l) » W C I M ). There is a similar screen on the
160
for enabling or disabling it for specific domains.
WorldClient Instant Messenger Skins
WCIM's interface is compatible with msstyles skins, which are readily available on the internet. Several styles are included, but to install a new style, download the
*.msstyles
file and place it under WCIM's \Styles\ folder in a subfolder with the same name as the file. For example, if the file was called Red.msstyles then the path for the file would be: "\.\Styles\Red\Red.msstyles"
Dropbox Integration
A new screen has been added to Ctrl+W|WorldClient (web mail)|Dropbox. Here you will find controls where you can enter your Dropbox "app key", "app secret", and privacy policy text. All are needed in order to enable the integrated service and they are all obtained when you register your WorldClient as a Dropbox "app" by visiting the Dropbox website. We cannot do this for you but it only needs doing once. Please see Knowledge
Base article 1166 for complete instructions on how to register your WorldClient as an app with Dropbox.
Once the "app key" and "app secret" are configured WorldClient will be able to connect their accounts to a Dropbox account. The first time a user logs into WorldClient theme or LookOut theme, the user will be presented with a dropdown at the top of the page.
The user has three options, view the dropdown on next login, never show it again, or go to the new Options | Cloud Apps view. On the Options | Cloud Apps view, the user can click the Setup Dropbox button. Doing so will open an OAuth 2.0 popup. The popup details what the user is connecting to, and what authorizations WorldClient is requesting. There is also a link to the privacy policy, and "Connect to Dropbox" button.
Once the user clicks the "Connect to Dropbox" button, the page will navigate to
Dropbox. If the user is not logged into Dropbox, Dropbox will present a site for them to either login or create an account. Once this step is completed, the user will be presented with another Dropbox page that asks if the user would like to allow
WorldClient to have full access to his/her account. Clicking "Allow", will take the user back to WorldClient and tell the user whether or not the authorization was a success.
This authorization is good for one week after which time the same screen is presented again and another access token is obtained and used for a subsequent week. Once authorization is completed, the user will be presented with a Dropbox icon next to each message attachment. Clicking the icon will result in the attachment being saved to the user's Dropbox account under the /WorldClient_Attachments folder.
In the Compose view for WorldClient and LookOut themes, users will be able to choose files from their Dropbox accounts by clicking the Dropbox icon in the HTML editor's toolbar (top left). This feature does not require the users to setup access to their accounts via the Options | Cloud Apps view and OAuth 2.0. It only requires the "app key" and "app secret".
Dropbox support is disabled by default, but can be enabled on the
279
screen in
MDaemon. If you wish to enable or disable Dropbox on a per user basis, you can do so by adding "DropboxAccessEnabled=Yes" to the User.ini.

End-to-end Email and Attachment Encryption
The WorldClient theme is equipped with support for end-to-end email and attachment encryption through Virtru. To enable this feature, the WorldClient user must switch to the WorldClient theme, go the the Options » Compose page, and click Enable Virtru.
This causes a button to appear on the Compose page that the user can click to encrypt his or her email before sending. This is an easy-to-use feature that doesn't require the user to remember or save any special passwords or keys. Recipients who use a Virtru-enabled client such as the WorldClient theme, or one of Virtru's other client plugins, can open and read the encrypted messages normally, without any additional steps. Recipients without a Virtru-enabled client will see a link to view the message in a special browser-based reader.
If you wish to prevent your users from being able to use Virtru encryption within
WorldClient, open the Domains.ini file in the MDaemon/WorldClient folder and add:
VirtruDisabled=Yes
.

Maximum number of concurrent sessions
This is the maximum number of sessions that may be connected to WorldClient at the same time.
Sessions not composing a message expire after xx inactive minutes
When a user is logged in to WorldClient but is not composing a message, this is the amount of time that their session will remain inactive before WorldClient will close it.
Sessions composing a message expire after xx inactive minutes
This timer governs how long a user
' s session will be kept open while they are composing a message and the session remains inactive. It is a good idea to set this timer higher than the
Sessions not composing a message...
timer, since inactivity time is typically greater while a user is composing a message. This is because composing a message requires no communication with the server until the message is sent.
Cache HTML templates to increase web server performance
Click this box to cause WorldClient to cache templates in memory rather than read them each time they need to be accessed. This can dramatically increase server performance but WorldClient will have to be restarted if you ever make a change to one of the template files.
Use cookies to remember logon name, theme, and other properties
Click this option if you want WorldClient to store each user
' s logon name, theme, and certain other properties in a cookie on his or her local computer. Using this feature gives your users a more "customized" login experience but requires that they have support for cookies enabled in their browsers.
Require IP persistence throughout WorldClient session
As an added security measure you can click this checkbox to cause WorldClient to
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 265
restrict each user session to the IP address from which the user connected when the session began. Thus, no one can "steal" the user
' s session since IP persistence is required. This configuration is more secure but could cause problems for users who may be using a proxy server or Internet connection that dynamically assigns and changes IP addresses.
Use HTTP Compression
Click this check box if you want to use HTTP compression in your WorldClient sessions.
Send anonymous usage data
By default WorldClient sends anonymous, benign usage data such as: the OS used, browser version used, language, and the like. This data is used by Alt-N
Technologies to help us improve WorldClient. Disable this option if you do not wish to send anonymous usage data.
Bind WorldClient
' s web server to these IPs/ports only
If you wish to restrict the WorldClient server to only certain IP addresses or ports then specify those IPs and ports here separated by commas. Use the format:
"IP_address:Port" to designate a port (for example, 192.0.2.0:80). If you do not include a port, then the default TCP port specified above and the default HTTPS port specified on the
268
screen will be used. Use "*" if you want
WorldClient to listen on all ports. For example, "*,*:80" would cause WorldClient to listen on all IP addresses, on the default ports specified (3000 and 443), and it would also listen on all IP addresses on port 80. If you leave this field blank then
WorldClient will monitor all IP addresses designated for your
152

4.6.1.3 SSL & HTTPS
MDaemon's built-in web server supports the Secure Sockets Layer (SSL) protocol. SSL is the standard method for securing server/client web communications. It provides server authentication, data encryption, and optional client authentication for TCP/IP connections. Further, because HTTPS support (i.e. HTTP over SSL) is built into all major browsers, simply installing a valid digital certificate on your server will activate the connecting client's SSL capabilities.
The options for enabling and configuring WorldClient to use HTTPS are located on the
SSL & HTTPS screen under S etup » W eb & I M S erv i ces » W orldCli ent (web mai l)". For your convenience, however, these options are also mirrored under "S ecuri ty » S ecuri ty
S etti ng s » S S L & T L S » W orldC li ent ".
For more information on the SSL protocol and Certificates, see:

This screen only applies to WorldClient when using MDaemon's built-in web server. If you configure WorldClient to use some other web server such as IIS, these options will not be used —
SSL/HTTPS support will have to be configured using your the other web server's tools.

HTTPS port
This is the TCP port that WorldClient will listen to for SSL connections. The default
SSL port is 443. If the default SSL port is used, you will not have to include the port number in WorldClient
' s URL when connecting via HTTPS (i.e. "https://example.com" is equivalent to "https://example.com:443").
This is not the same as the WorldClient port that is designated on the

Host name
When creating a certificate, enter the host name to which your users will connect
(for example, "wc.example.com").
Organization/company name
Enter the organization or company that "owns" the certificate here.
Alternative host names (separate multiple entries with a comma)
MDaemon does not support multiple certificates — all WorldClient domains must share a single certificate. If there are alternative host names to which users may be connecting and you want this certificate to apply to those names as well, enter those domain names here separated by commas. Wildcards are permitted, so
"
*.example.com
" would apply to all sub domains of
example.com
(for example,
"
wc.example.com
", "
mail.example.com
", and so on).
Encryption key length
Choose the desired bit-length of the encryption key for this certificate. The longer the encryption key the more secure the transferred data will be. Note, however, that not all applications support key lengths longer than 512.
Country/region
Choose the country or region in which your server resides.
Hash algorithm
Choose the hash algorithm that you wish to use: SHA1 or SHA2. The default setting is SHA2.

Using Let's Encrypt to Manage Your Certificate
To support
563
for
565
,
568
, and
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
272 MDaemon Messaging Server 17.0
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

4.6.1.8 Dropbox
WorldClient is equipped with direct support for Dropbox, which allows your users to save file attachments to their Dropbox accounts, and to insert direct links to Dropbox files in outgoing messages. To provide this feature to your WorldClient users, you must set up your WorldClient as a Dropbox app on the Dropbox Platform . This is a simple process, requiring you only to sign in to a Dropbox account, create a unique name for an app with Full Dropbox access, specify the Redirect URI to WorldClient, and change
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
280 MDaemon Messaging Server 17.0
one default setting. Then, you will copy and paste the Dropbox App Key and App
Secret from there to the options on this screen in MDaemon. After that your users will be able to link their Dropbox accounts to WorldClient when they next sign in to
WorldClient. For step-by-step instructions on how to create your Dropbox app and link it to WorldClient, see:
Creating and Linking Your Dropbox App
281
below.
When you create your Dropbox app it will initially have "Development" status. This allows up to 500 of your WorldClient users to link their Dropbox accounts to the app.
According to Dropbox, however, "once your app links 50 Dropbox users, you will have two weeks to apply for and receive Production status approval before your app's ability to link additional Dropbox users will be frozen, regardless of how many users between 0 and 500 your app has linked." This means that until you receive production approval,
Dropbox integration will continue to work but no additional users will be able to link their accounts. Obtaining production approval is a straightforward process to ensure that your app complies with Dropbox's guidelines and terms of service. For more information, see the Production Approval section of the Dropbox Platform developer guide .
Once your WorldClient app is created and configured properly, each WorldClient user will be given the option to connect their account to their Dropbox account when they sign in to WorldClient. The user is required to log in to Dropbox and grant permission for the app to access the Dropbox account. Then the user will be redirected back to
WorldClient using a URI that was passed to Dropbox during the authentication process.
For security that URI must match one of the Redirect URIs (see below) you specified on your app's info page at Dropbox.com. Finally, WorldClient and Dropbox will exchange an access code and access token, which will allow WorldClient to connect to the user's
Dropbox account so that the user can save attachments there. The exchanged access token expires every seven days, meaning that periodically the user must reauthorize the account to use Dropbox. Users can also manually disconnect their account from
Dropbox, or reauthorize it when necessary, from the Cloud Apps options screen within
WorldClient.
Dropbox Integration
Enable Dropbox Integration
Once you have created your Dropbox app and linked it to WorldClient, click this checkbox to allow your WorldClient users to link to their Dropbox accounts. If you wish to enable or disable Dropbox on a per user basis, you can do so by adding
"DropboxAccessEnabled=Yes (or No)" to the User.ini.
Dropbox app key and app secret
The App key and App secret are located on your app's info page at Dropbox.com.
Enter them here to link WorldClient to your Dropbox app.
Redirect URI
You must specify a Redirect URI on your app's info page at Dropbox.com. MDaemon automatically displays a URI here that you should be able to use there. You can, however, add multiple Redirect URIs. Therefore you could add a URI for each of your domains and even one for localhost, which might be used if signing in to WorldClient from the machine on which the server is running.
For example: https://mail.company.test/WorldClient.dll?
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 281
View=OAuth&AuthRequest=Dropbox https://example.com/WorldClient.dll?

Dropbox requires your Redirect URIs to be secure, therefore
268
must be enabled for WorldClient.
Edit text of privacy policy
Click this button to edit the text file containing your WorldClient App's privacy policy. Because Dropbox requires that an approved privacy policy be periodically presented to your users, a "Privacy Policy" link to the contents of this file is provided on the Connect to Dropbox page displayed to your users. That link opens a small window containing the text and a Download button that users can click to download the file. Use HTML code in the file if you wish to format the text or want it to contain any links.

Customizing Standard WorldClient Features
There are various standard WorldClient features that you can customize by editing certain files in the MDaemon\WorldClient\ folder:
Categories
WorldClient supports categories for email in the LookOut and WorldClient themes. Users can add the Categories column to the message list by going to "Options » Columns" and checking "Categories" in the Message List section. To select categories for one or multiple messages, select the messages and right-click one of them. Use the context menu to set the category.
Administrators can create custom categories. There are two files for this purpose: DomainCategories.json and PersonalCategories.json.
Domain Categories are enabled globally by default. To disable them open
MDaemon\WorldClient\Domains.ini
, and in the [Default:Settings] section change the value of "DomainCategoriesEnabled=" from "Yes" to "No".
Users are able to add and edit their own categories by default. If you wish to disable this option, you can do so per user or globally by changing the value of
"CanEditPersonalCategories=" from "Yes" to "No". The user option is located in the [User] section of the User.ini file and the global option is in the
Domains.ini
file under the [Default:UserDefaults] section.
If Domain Categories are enabled, and a user is not allowed to edit personal categories, the user will only see the categories listed in
DomainCategories.json
.
If Domain Categories are disabled, and a user is not allowed to edit personal categories, the user will see the categories listed in PersonalCategories.json.
The file CustomCategoriesTranslations.json is used to support your custom category names in multiple languages. Add any necessary custom category translatations to that file to make it possible for WorldClient to recognize a category saved to an event, note, or task in one language as the equivalent

They can edit product INI files, designate other users as Domain administrators, manage passwords, and do many other things; they have complete administrative control.
Domain Administrators — Similar to Global administrators, Domain administrators also have control over the users and settings accessible via Remote
Administration. Their administrative control, however, is limited to the domain or domains to which they have been given access and the permissions designated on the
607
screen. Domain administrators and the domains over which they have control are designated from within Remote Administration by a
Global administrator, or by another Domain administrator with access to those domains.
Users — The lowest possible level of Remote Administration access is User access.
MDaemon users can sign in to the remote administration interface and, for example, view their individual account settings as well as edit their MultiPOP entries, mail filters, Autoresponders, and so on. The type and number of settings that can be edited depends on the permissions given in each user
' s account settings
Everyone who has permission to access both WorldClient and Remote Administration can access Remote Administration from within WorldClient, rather than having to sign in to both separately. Remote Administration is opened in a separate browser window from within WorldClient by clicking the "Advanced Settings" link under "Options".

Sessions expire after xx inactive minutes
When you are logged in to Remote Administration, this is the amount of time that your session is allowed to be inactive before Remote Administration will close it. The default is 15 minutes.Use cookies to remember logon name and other properties
By default the Remote Administration interface uses cookies so that the user's browser can remember the user's login name and other properties. Disable this checkbox if you do not wish to use cookies. Using this feature gives users a more customized login experience but requires that they have support for cookies enabled in their browser.
Require IP persistence throughout remote administration session
As an added security measure you can click this checkbox to cause Remote
Administration to restrict each session to the IP address from which you connected when the session began. Thus, no one can "steal" the session since IP persistence is required. This configuration is more secure but could cause problems if you are using a proxy server or Internet connection that dynamically assigns and changes IP addresses.
Stop Remote Administration when MDaemon stops
Click this option if you want Remote Administration to be shut down whenever
MDaemon is shut down. Otherwise, Remote Administration will continue to run in the background.
Send anonymous usage data
By default MDaemon's Remote Administration web client sends anonymous, benign usage data such as: the OS used, browser version used, language, and the like. This data is used by Alt-N Technologies to help us improve Remote Administration.
Disable this option if you do not wish to send anonymous usage data.
Remote Administration URL
This is the URL that WorldClient will use internally when users click the Advanced
Settings link to edit their account settings via Remote Administration. If you are running Remote Administration with the built-in web server, then leave this field blank. If you are using an alternate web server such as IIS, and you have configured
Remote Administration to run at an alternate URL or IP address, then specify that
URL here.
Bind Remote Administration's web server to these IPs only
If you wish to restrict the remote administration server to only certain IP addresses, specify those addresses here separated by commas. If you leave this field blank then Remote Administration will monitor all IP Addresses that you have designated for your

4.6.2.2 SSL & HTTPS
MDaemon's built-in web server supports the Secure Sockets Layer (SSL) protocol. SSL is the standard method for securing server/client web communications. It provides server authentication, data encryption, and optional client authentication for TCP/IP connections. Further, because HTTPS support (i.e. HTTP over SSL) is built into all major browsers, simply installing a valid digital certificate on your server will activate the connecting client's SSL capabilities.
The options for enabling and configuring Remote Administration to use HTTPS are located on the SSL & HTTPS screen under S etup » W eb & I M S erv i ces » R emote
A dmi ni s trati on ". For your convenience, however, these options are also mirrored under
"S ecuri ty » S ecuri ty S etti ng s » S S L & T L S » R emote A dmi ni s trati on".
For more information on the SSL protocol and Certificates, see:

Setup Menu 291
This screen only applies to Remote Administration when using
MDaemon's built-in web server. If you configure Remote
Administration to use some other web server such as IIS, these options will not be used — SSL/HTTPS support will have to be configured using your the other web server's tools.
Accept the Following Connection Types
HTTP only
Choose this option if you do not wish to allow any HTTPS connections to Remote
Administration. Only HTTP connections will be accepted.
HTTP and HTTPS
Choose this option if you want to enable SSL support within Remote Administration, but do not wish to force your Remote Administration users to use HTTPS. Remote
Administration will listen for connections on the HTTPS port designated below, but it will still respond to normal http connections on the Remote Administration TCP port designated on the
288
screen.
HTTPS only
Choose this option if you wish to require HTTPS when connecting to Remote
Administration. Remote Administration will respond only to HTTPS connections when this option is enabled — it will not respond to HTTP requests.
HTTP redirected to HTTPS
Choose this option if you wish to redirect all HTTP connections to HTTPS on the
HTTPS port.
HTTPS port
This is the TCP port that Remote Administration will listen to for SSL connections.
The default SSL port is 443. If the default SSL port is used, you will not have to include the port number in Remote Administration
' s URL when connecting via HTTPS
(i.e. "https://example.com" is equivalent to " https://example.com:443") .
This is not the same as the Remote Administration port that is designated on the
288
screen. If you are still allowing HTTP connections to Remote Administration then those connections must use that other port to connect successfully. HTTPS connections must use the HTTPS port.
Select certificate to use for HTTPS/SSL
This box displays your SSL certificates. Click a certificate to designate it as the one
Remote Administration will use. Double-click a certificate to open it in the Certificate dialog for review.

MDaemon does not support multiple certificates for Remote
Administration. All domains must share a single certificate. If you have more than one domain then enter those domain names (and any others that you wish to use to access Remote
Administration) into the option called "Alternative host names
(separate multiple entries with a comma)" outlined below.
Delete
Select a certificate in the list and then click this button to delete it. A confirmation box will open and ask you if you are sure that you want to delete the certificate.

Host name
When creating a certificate, enter the host name to which your users will connect
(for example, "wc.example.com").
Organization/company name
Enter the organization or company that "owns" the certificate here.
Alternative host names (separate multiple entries with a comma)
MDaemon does not support multiple certificates — all Remote Administration domains must share a single certificate. If there are alternative host names to which users may be connecting and you want this certificate to apply to those names as well, enter those domain names here separated by commas. Wildcards are permitted, so
"
*.example.com
" would apply to all sub domains of
example.com
(for example,
"
wc.example.com
", "
mail.example.com
", and so on).

Using Let's Encrypt to Manage Your Certificate
To support
563
for
565
,
568
, and
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
294 MDaemon Messaging Server 17.0
host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

4.6.3 Attachment Linking
Attachment Linking (S etup » W eb & I M S erv i ces » A ttachment L i nk i ng ) is a feature that makes it possible for MDaemon to remove all attachments from incoming email messages, store them in a designated location, and then place URL links to the files in each message from which they are extracted. The recipients can then click those links to download the files. This can greatly speed up mail processing when your users retrieve their messages or synchronize their mail folders, since the messages will be devoid of large attachments. It can also provide increased security and an increased level of protection for your users, because attachments can be stored in a central location for monitoring by the administrator and will not be downloaded automatically to mail clients where they might be executed automatically. Further, if you choose the
"Let WorldClient automatically manage Attachment Linking" option, management of the file locations and the WorldClient URL is handled automatically. If you choose to manage Attachment Linking manually, you can specify the location where the files will be stored, and you can use special macros to make the location dynamic. In order for
Attachment Linking to work, it must be enabled globally using the option on this screen, and each Account that you wish to use it must be configured specifically to do so on the
621
screen of the Account Editor. On that same screen there is also an option for applying Attachment Linking to outbound messages as well; the account's outbound messages will have attachments extracted and replaced with a link to the stored files. Finally, the links to the attachments that MDaemon will place in messages do not contain direct file paths. Instead they contain a unique identifier (GUID) that the server uses to map the file to the actual path. This GUID map is stored in the
AttachmentLinking.dat
file.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 299
Attachment Linking will try to use the file name provided in the
MIME headers (if present). If the file name is longer than 50 characters then only the last 50 characters will be used. If the file name is missing an extension, ".att" will be appended.
By default, the Attachment Linking feature places the text,
"MDaemon replaced the following files with these links:" into certain emails. If you wish to change that text, add the following key to your MDaemon.ini file, located in the \app\ folder, then restart MDaemon:
[AttachmentLinking]
HeaderText=This Is My Text.
Enable attachment linking
Click this checkbox to enable Attachment Linking for all accounts that are specifically configured to use it on the
621
screen of the Account
Editor. When you enable this global option you will be asked if you also wish to enable the account specific option for all MDaemon accounts. If you choose "Yes" then Attachment Linking will be enabled for all accounts, and the corresponding option on the
686
template will also be enabled. If you choose "No" then the Attachment Linking feature will be enabled but the account specific option will not—you must manually activate it for each account that you wish to use it.
When Attachment Linking is enabled, the WorldClient server must remain active.
Let WorldClient automatically manage Attachment Linking
This is the default option when Attachment Linking is enabled. Use this option if you wish to let WorldClient handle Attachment Linking automatically. Extracted files will be stored at: "...\MDaemon\Attachments\$DOMAIN$\$MAILBOX$\".
Manually configure Attachment Linking
Choose this option if you wish to designate the folder in which extracted file attachments will be stored. You must designate both the attachment path and the WorldClient URL when you choose this option.
Attachment path
Use this text box to designate the folder in which to store extracted file attachments. You can set a static file path or use
670
and
macros to make the path dynamic. For example, "$ROOTDIR$\Attachments
712
\$DOMAIN$\
" will group all attachments into a subfolder named for the domain to which the user belongs, which is under another subfolder called
"Attachments" contained in MDaemon's root folder (usually C:\MDaemon\).
So, for "[email protected]" the above example would cause the extracted attachments to be placed in the subfolder, "C:\MDaemon\Attachments
\example.com\
." You could further subdivide attachment storage by appending the "$MAILBOX$" template macro to the above example. This would cause user1's files to be stored in a subfolder beneath "\example.com\" called "user1." Therefore the new file path would be: "C:\MDaemon
\Attachments\example.com\user1\
."

WorldClient URL
Enter WorldClient's URL here (e.g. "http://mail.example.com:3000/
WorldClient.dll
"). MDaemon will use this URL when inserting the links to extracted attachments in messages.
Ignore attachments smaller than this many KB (0 = none)
This is the minimum size required before an attachment will be extracted from a message. Use this option if you do not wish to extract smaller attachments. If set to
"0" then Attachment Linking will extract all attachments, no matter how small.
Delete attachments older than this many days (0 = never)
Use this option if you wish to set a limit on the number of days that attachments will be stored. As part of the daily cleanup event MDaemon will remove any stored attachments that are older than the designated limit, if those attachments are contained within the default attachment folder or one of its subfolders. The default folder is: "<MDaemonRoot>\Attachments\...". Attachments will not be removed if you customize the attachment folder to point elsewhere. This option is disabled by default (set to "0").
Delete attachments from disk when messages are deleted
Click this option if you want to delete extracted attachments from the server whenever the messages to which they are linked are deleted.
When this option is enabled and a user collects his email via a
POP3 client that is not configured to leave messages on the server, then all of his extracted attachments will be irretrievably lost. If this option is not enabled then no attachments will be lost, but a great deal of your hard drive space could eventually be taken up by outdated and useless files that their original recipient no longer wants or needs.
Virtually all POP clients have the ability to leave messages on the server.
Extract quoted printable “text/plain” attachments
By default, quoted printable
text/plain
attachments will not be extracted. Click this checkbox if you wish to include them in automatic extraction.
White List
Click this button to open the Attachment Linking white list. Include any file names that you do not wish to extract from messages. Winmail.dat is included on this list by default.

4.6.4 CalDAV & CardDAV
Setup Menu 301
CalDAV is an Internet standard for managing and sharing calendars and scheduling information. MDaemon's CalDAV support makes it possible for your accounts to use any client that supports CalDAV to access and manage their personal calendars and tasks.
They can also access any
251
or
629
calendars or tasks according to their
253
. CardDAV is a standard for accessing contacts/address book information. MDaemon's CardDAV server allows an authenticated CardDAV client to access the contact information that is stored in MDaemon.
Enable CalDAV & CardDAV Server
CalDAV/CardDAV support is enabled by default. However, WorldClient is required and therefore
263
in order to use it. Disable this option if you do not wish to support CalDAV or CardDAV. To enabled/disable it for individual domains, use the options below.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
302 MDaemon Messaging Server 17.0
Changing the Default CalDAV/CardDAV Setting for Domains
Initially, all of MDaemon's domains will have CalDAV/CardDAV enabled or disabled based the Default selection in the Select domain drop-down list. To change the default setting:
1. In the Select domain drop-down list, choose Default.
2. Check the box next to Enable CalDAV & CardDAV service for this domain if you want CalDAV/CardDAV to be enabled for all domains by default, or clear the box if you want it to be disabled by default.
3. Click Ok.
Enabling/Disabling CalDAV/CardDAV for Specific Domains
To override the Default CalDAV/CardDAV setting for individual domains:
1. In the Select domain drop-down list, choose a specific domain.
2. Check the box next to Enable CalDAV & CardDAV service for this domain if you want CalDAV/CardDAV to be enabled for the domain, or clear the box if you want it to be disabled.
3. Click OK.
Logging
Log level
Use this drop-down list to designate the degree to which CalDAV/CardDAV activities will be logged. There are six possible levels of logging: 1-Debug logging, 2-Normal logging (default), 3-Warnings and errors only, 4-Errors only, 5-Critical errors only, and 6-No logging. This is a global setting—it cannot be applied to specific domains
Enable HTTP request and response logging
If enabled, this will create an MDWebDAV folder in MDaemon's logs folder. All data sent and received by the CalDAV/CardDAV server will be logged to that folder. Ordinarily this option would only be used for diagnostics and shouldn't be enabled unless you are instructed by Technical Support to do so.
Configuring CalDAV Clients
To configure clients that support RFC 6764 (Locating Services for Calendaring
Extensions to WebDAV (CalDAV)) , only the server, user name, and password should be required. You can setup your DNS records to point the client to the correct URL. When a DNS record has not been configured, the user can enter a special "well-known URL" in the client: "hostname/.well-known/caldav". For example: http://example.com:3000/
.well-known/caldav
. WorldClient's built-in web server support the well-known URL.
Clients that do not support automatically locating the CalDAV service, such as Mozilla
Thunderbird via the Lightning plugin, will require a full URL for each Calendar and Task list. MDaemon's CalDAV URLs are constructed like this:

Client Setup at altn.com.
Configuring CardDAV Clients
To configure clients that support RFC 6764 (Locating Services for Calendaring
Extensions to WebDAV (CalDAV) and vCard Extensions to WebDAV (CardDAV)) , only the server address, username, and password should be required. Apple Address Book and iOS support this standard. DNS records can be setup that point the client to the correct URL. When a DNS record has not been configured, clients query a "well-known
URL," which in the case of CardDAV is /.well-known/carddav. WorldClient's built-in web server supports this well-known URL. Clients that do not support automatically locating the CardDAV service will require a full URL.
Notable CardDAV clients are Apple Contacts (included with Mac OS X), Apple iOS
(iPhone), and Mozilla Thunderbird via the SOGO plugin .
As of OS X 10.11 (EL Capitan), the Apple Contacts application only supports a single collection/folder . When the CardDAV server detects the Apple Contacts application, it will only return the authenticated user's default contacts folder. In addition, OS X 10.11 (EL Capitan) has a known issue that prevents a CardDAV account from being added using the
"Advanced" view of the dialog.
Accessing address books
The "addressbook" path is a shortcut to your own default addressbook.
http://[host]/webdav/addressbook
- your default contacts folder.
http://[host]/webdav/addressbook/friends
- your "friends" contacts folder.
http://[host]/webdav/addressbook/myfolder/personal
- your "personal" contacts folder in a subfolder called "myfolder".

The "contacts" path is a shortcut to shared contact folders.
http://[host]/webdav/contacts/example.com/user2
- [email protected]'s default contact folder http://[host]/webdav/contacts/example.com/user2/myfolder
[email protected]'s "myfolder" contact folder
Access public folders, to which you have access
The "public-contacts" path is a shortcut to public contact folders.
http://[host]/webdav/public-contacts/example.com
- example.com's default contact folder http://[host]/webdav/public-contacts/foldername
- "foldername" contact folder in the root of the public folder hierarchy
Special care should be taken if testing the OutlookDAV client.
OutlookDAV only supports the default MAPI profile. If multiple
MAPI profiles exist, the client may issue delete commands to the server for all of the items that were returned by the server.

4.6.5 XMPP
MDaemon is equipped with an Extensible Messaging and Presence Protocol (XMPP) server, sometimes called a Jabber server. This allows your users to send and receive instant messages using
259
and third-party XMPP clients , such as Pidgin , Gajim , Swift and many others. Clients are available for most operating systems and mobile device platforms.
The XMPP server is installed as a Windows service, and the default server ports are
5222 (SSL via STARTTLS) and 5223 (dedicated SSL). The XMPP server will use
MDaemon's SSL configuration if it is enabled in MDaemon. Also, some XMPP clients use
DNS SRV records for auto-discover of host names. Please refer to http://wiki.xmpp.org/ web/SRV_Records for more information.
Users sign-in through their chosen XMPP client using their email address and password.
Some clients, however, require the email address to be split into separate components for signing in. For example, instead of "[email protected]," some clients require you to use "frank" as the Login/Username and "example.com" as the Domain.
For multi-user/group chat service, clients typically display this as "rooms" or
"conferences." When you want to start a group chat session, create a room/ conference (giving it a name) and then invite the other users to that room. Most clients don't require you to enter a server location for the conference; you only need to enter a name for it. When you are required to do so, however, use
"conference.<your domain>" as the location (e.g. conference.example.com). A few clients require you to enter the name and location together in the form:
"room@conference.<your domain>" (e.g. [email protected]).
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 307
Some clients (such as Pidgin ), support the user search service, allowing you to search the server for users by name or email address, which makes adding contacts much easier. Usually you will not have to provide a search location, but if asked to do so, use
"search.<your domain>" (e.g. search.example.com). When searching, the % symbol can be used as a wildcard. Therefore you could use "%@example.com" in the email address field to display a list of all users with an email address ending in
"@example.com."

attempt
to wait after the last time you checked for an update, whether the update was triggered by the scheduler or manually. The scheduler and manually triggered updates are given precedence over this setting and will therefore reset this counter if an AntiVirus update event is triggered by one of those other methods. Thus, for example, if you have this option set to check for updates every 240 minutes and you manually check for an update after 100 minutes, this counter will be reset to 240.

Click S etup » Ev ent S cheduli ng to open MDaemon
' s Event Scheduler. Using this screen you can schedule MDaemon
' s Remote mail processing events as extensively or as simply as you prefer. You can use a counter to process mail at regular intervals, or you can schedule exact times for mail delivery and collection using the
316 screens. You can also set conditions that will trigger mail processing at unscheduled times such as when a certain number of messages are waiting to be delivered, or when a message has been waiting a specified amount of time. Further, you can create custom schedules that you can assign to custom remote mail queues. Custom schedules make it possible for you to set different schedules for different types of messages. For example, you could create schedules for large messages, mailing list messages, certain domains, and so on.
Use the
308
section of the Event Scheduler to schedule how often MDaemon will check for AntiVirus updates.
Mail Delivery/Collection Global Settings

other event to trigger mail processing, MDaemon will immediately process and deliver all remote mail that has been queued within the number of minutes designated in the Only deliver mail queued within the last [xx] minutes option below.
...including mail stored for gateway domains
Click this check box if you also want messages for Domain Gateways to be delivered immediately. However, this only applies to gateways with the Deliver
stored messages each time MDaemon processes remote mail option enabled on the
201
screen of the Gateway Editor.
Only deliver mail queued within the last [xx] minutes (0=send all)
This option governs how recently messages must have been queued before the
Deliver queued mail immediately whenever possible option above will spool them for delivery. When that option triggers remote mail processing, instead of attempting to deliver everything in the queue, MDaemon will process only those messages that were queued within the designated number of minutes. The entire queue will still be processed, however, when the Process...queue toolbar button is pressed or when any other normal scheduling event triggers remote mail processing. By default, this option is set to one minute. You can set it to “0” if you wish to process the entire queue every time remote mail processing is triggered, but that is not recommended since it is much less efficient.
The above options only apply to the Default schedule. They are unavailable for custom schedules (see the Name... option below).
Delivery Schedules
Name...
Use this drop-down list box to select a schedule to edit. The Default schedule will always be used for the regular, remote mail queue and for DomainPOP and MultiPOP collected mail. For configurations using dialup services, the Default schedule will also be used for LAN Domains, which are remote domains that you have designated as residing on your local area network and therefore do not require RAS dialup. Other schedules can be assigned to custom remote mail queues, and messages can be routed to those

However, if you delete a custom queue then any schedules associated with that queue will also be deleted, and all associated content filter rules as well.
Deliver queued mail at this interval (in minutes)
Click the check box and slide this bar left or right to specify the time interval between mail processing sessions. It can be configured to count down from a range of 1 to 60 minutes. After that amount of time, MDaemon will process remote mail before beginning the countdown again. When this check box is cleared,
Remote Mail
processing intervals will be determined by the other scheduling options.
Deliver mail [xx] minutes after the last time it was delivered
Use this option when you want a remote mail processing session to occur at a regular time interval after the last session occurred, regardless of the trigger that initiated the session. Unlike the rigidly fixed intervals used when setting up specific times or when using the Deliver queued mail at this interval slide bar, this option
' s time interval will reset each time mail is processed.
Deliver mail if [xx] or more messages are queued
When this option is enabled, MDaemon will trigger a mail session whenever the number of messages waiting in the remote queue meets or exceeds the number that you specify here. These mail sessions are in addition to any other normally scheduled sessions.
Deliver mail if messages are [xx] minutes old or older
When this box is checked, MDaemon will trigger a mail session whenever a message has been waiting in the queue for the number of minutes specified.
These sessions are in addition to any other normally scheduled sessions.
Queues
Attach this schedule to this queue
Use this option to associate the selected schedule with a specific custom remote mail queue. You can then use the content filter to create rules that will place certain messages in that queue. For example, if wanted to schedule mailing list messages destined for remote addresses to be delivered at some specific time, then you could create a custom queue for those messages, create a rule to put all of them into your custom queue, and then create a custom schedule and assign it to that queue.

local mail via POP, IMAP, or WorldClient rather than for all users at once. However, because MultiPOP collection is triggered by a user checking his email, any new
MultiPOP messages collected will not be visible to the user until he checks his mail
again
. Thus, he would need to check his mail twice in order to see new MultiPOP messages. The first time to trigger MultiPOP and a second time to see the mail that was collected.
But no more often than XX times per hour
In order to reduce the load that extensive use of MultiPOP can potentially place on your MDaemon, you can use this control to specify a maximum number of times per hour that MultiPOP can be collected for each user.
Wait at least XX minutes between each collection
This option can help to reduce the load on the mail server by limiting how frequently MultiPOP messages can be collected by each user. It will restrict
MultiPOP mail collection to once every so many minutes per user. Specify the number of minutes that you wish to require the user to wait before being allowed to check MultiPOP again.

MDaemon will push those settings to the corresponding client screens as necessary, each time an Outlook Connector user connects to the server. The OC Client Settings are only sent to clients when one of the settings has changed since the last time the client connected and received them. If the option below to "Allow OC users to override
pushed settings" is enabled, users can override any pushed settings on their individual clients. If that option is disabled, then all of the client screens are locked; Outlook
Connector users can make no changes.
To allow for certain settings that must be different for each user or domain, OC Client
Settings supports macros such as $USERNAME$, $EMAIL$, and $DOMAIN$. These macros will be converted to data specific to the user or domain when pushing settings to a client. Take care not to place any static values in any fields that should use a macro, such as putting something like "Frank Thomas" in the Your Name field. To do so would cause every Outlook Connector user who connects to MDaemon, to have his or her name set to "Frank Thomas." For your convenience there is a Macro Reference button on the

Push client settings to OC users
Enable this option if you wish to push the preconfigured settings on the OC Client
Settings screens to your Outlook Connector users whenever they connect. The OC
Client Settings are only sent to clients when one of the settings has changed since the last time the client connected and received them. This option is disabled by default.
Allow OC users to override pushed settings
If this option is enabled, users can override any of the pushed settings on their individual clients. If it is disabled, all of the client screens are locked; Outlook
Connector users can make no changes.
Allowing users to override pushed settings will not prevent the server from pushing future changes to the clients. For example, if a user changes one of his Outlook Connector settings and then the administrator makes some change to one of the OC Client Settings screens on the server, all of the OC
Client Settings will be pushed to that user's client the next time it connects to the server. Therefore even the setting that the user had previously overridden will be changed to match the settings on the server.
Automatically Discovering OC Settings
When first configuring the Outlook Connector plug-in on the client, users can click the
"Test & Get Account Settings" button on the General screen after entering their User
Name and Password. This causes Outlook Connector to attempt to validate the credentials and automatically retrieve the Server Information for the account.
To connect to the server, first the client will try common FQDN values. For IMAP, it tries to authenticate to mail.<domain> (e.g. mail.example.com) using the dedicated
SSL port, then the non-SSL port with TLS. If that doesn't succeed then it will repeat the same process for imap.<domain>, then <domain>, and finally, imap.mail.<domain>
. If all attempts fail then unencrypted sign-in is attempted for those same locations.
For SMTP, it tries mail.<domain> using port 587, 25, and then 465, first using SSL and then TLS. This is repeated for smtp.<domain>, <domain>, and then smtp.mail.<domain>
. If all attempts fail then unencrypted sign-in is attempted for those same locations.

By default Outlook Connector clients are set to save the user password, so that when Outlook is started it will automatically sign in to the email account without asking for credentials. Disable this option if you wish to require users to enter their password when starting Outlook.
Macro Reference
To allow for certain settings that must be different for each user or domain, OC Client
Settings supports macros such as $USERNAME$, $EMAIL$, and $DOMAIN$. These macros will be converted to data specific to the user or domain when pushing settings to a client. Take care not to place any static values in any fields that should use a macro, such as putting something like "Frank Thomas" in the Your Name field. To do so would cause every Outlook Connector user who connects to MDaemon, to have his or her name set to "Frank Thomas." Click the Macro Reference button to view the list of available macros:

Purge & Compact Database
Purge database on Outlook shutdown
To conserve disk space and improve performance, by default Outlook Connector is set to purge/delete the message body of old messages when you shut down
Outlook. This does not remove the message headers nor does it affect the original messages stored on the server; it simply removes the locally cached body of old messages. Whenever you open an old message that has been purged in the past, the message body will be downloaded again to your computer. Further, only email message bodies are purged; this doesn't affect Contacts, Calendars, Tasks,
Journals, or Notes. Disable this option if you do not wish to purge the database at shutdown.
Purge message body of messages older than XX days (0=never)
Use this option to designate how old a message must be for its message body to be purged at Outlook shutdown. By default a message must be more than 30 day old for it to be purged. Its age is based on the message modified date. Use "0" in this option if you never wish them to be purged.
Compact Database
Compact database on Outlook shutdown
To conserve disk space and improve performance, by default Outlook Connector is set to compact and defragment the locally cached messages database file when the user shuts down Outlook. Outlook must shutdown cleanly, however, for the compact action to occur; if Outlook crashes or you use the Task Manager to "End Task" then the database will not be compacted. You can use the options in the Configuration section below to designate how often this will occur and whether or not you will be prompted before it does.
Configuration
Prompt me to Purge/Compact on Outlook shutdown
Use this option if you want users to be prompted before Outlook Connector will purge or compact the database file at shutdown. If the user clicks Yes then it will perform the compact or purge actions, displaying a progress indicator as it does so.
Clear this checkbox if you do not want users to be prompted; at shutdown Outlook
Connector will begin purging or compacting the database automatically, displaying a progress indicator when doing so.
Run Purge/Compact on shutdown every XX days (0=always)
This option controls how often Outlook Connector will purge or compact the database at shutdown. By default this option is set to 7 days, meaning that it will run the Purge/Compact process at shutdown once every seven days. Set this option to "0" if you wish to purge/compact the database every time a user shuts down
Outlook.

4.9 Mobile Device Management
4.9.1 ActiveSync for MDaemon
4.9.1.1 ActiveSync for MDaemon
Setup Menu 335
MDaemon includes support for "ActiveSync for MDaemon," which is an over-the-air
(OTA) ActiveSync server that is an optional add-on for MDaemon Private Cloud. This server is capable of synchronizing a user's Email and PIM data (i.e. Contacts,
Calendars, and Tasks) between his MDaemon/WorldClient account and an ActiveSync capable device. MDaemon's ActiveSync options are located under: S etup » M obi le
Dev i ce M anag ement. . . » A cti v eS ync
.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
336 MDaemon Messaging Server 17.0
ActiveSync is a web-service extension that only works on ports 80 (for http) and 443
(for https). This is an ActiveSync implementation requirement. If ActiveSync is enabled and you are using WorldClient's built-in web server, but it is not running on port 80 or
443, then it will automatically begin running on port 80 in addition to whatever other ports you have configured on the
263
and
268
screens. If you are using another server for WorldClient such as IIS then you must manually configure it to use port 80 or 443.
If you intend to run ActiveSync under IIS you must call the ActiveSync DLL
(MDAirSync.dll) when "/Microsoft-Server-ActiveSync" is requested. This is the request that all the ActiveSync clients will use. Some versions of IIS do not have this capability without downloading, installing, and configuring third party software.
All first time syncs with ActiveSync are a one way sync from the server to the device. You will lose related data on the device when you sync with ActiveSync for the first time. This is an ActiveSync implementation requirement. You should therefore backup your device data before using ActiveSync for the first time. Most devices that support ActiveSync warn the user that "device data will be lost," but some do not.
Enabling/Disabling ActiveSync
Click Enable ActiveSync for MDaemon Service to turn on ActiveSync for MDaemon.
Then you can use the
352
options to control whether or not it is available to all or some of your domains.
Advanced Interface Options
Enable advanced management options
By default the
374
and
376
screens are hidden from the navigation pane on the left side of the Mobile Device Managements dialog. These screens contain options governing various ActiveSync system settings and diagnostics tools, and in most cases they will rarely need to be accessed or adjusted by anyone.
Enable this option if you want them to be visible.
Enable editing of advanced policy options
Enable this option if you want the Advanced Settings tab to be visible on the
344

ActiveSync Autodiscover Service
MDaemon supports the ActiveSync Autodiscover Service, which allows users to set up an ActiveSync account with just their email address and password, without needing to know the host name of the ActiveSync server. Autodiscover requires
268
to be enabled, and for most systems it also requires that a new CNAME or A-record be added to DNS. "autodiscover.<your-MDaemon-server>.com" should resolve to the MDaemon server running ActiveSync (for example, autodiscover.example.com).

Device Protocol Restrictions
Use the options located under "M obi le Dev i ce M anag ement... » A cti v eS ync » Protocol
R es tri cti ons " to tell certain clients and devices that they are restricted to specific
ActiveSync protocols. This is useful when, for example, a certain type of device is found to have unreliable support for one protocol but reliable support for another. Using the
338
dialog, you can define restrictions based on User
Agent or Device Type, and restrict the devices to any of the following ActiveSync protocol versions: 2.5, 12.0, 12.1, 14.0, and 14.1.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
338 MDaemon Messaging Server 17.0
By default, protocol restrictions do not prevent a client from attempting to use a different protocol; they tell the client which protocols to use. If a client attempts to use a restricted protocol anyway, MDaemon will still allow the connection. If you wish to deny connections that attempt to use restricted protocols, use the Enforce all protocol restrictions option below.

Add/Edit Protocol Restriction
User-Agent or Device Type Filter
Enter the User Agent or Device Type to which the restriction will apply. When identifying the agent, MDaemon uses up to and including the first "/" character in the string, if one is present. If not, then the entire string is used. If you do not know the exact name of the User Agent or Device Type, once the client has connected to MDaemon ActiveSync (MDAS) you can go to the
358
screen, select the client from the list, and click Details. You can also find this info by examining the MDAS log file directly.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 339
Allowed Protocol Versions
Click each protocol that you wish to support for the device or agent. When the specified client connects to MDaemon it will be told to use only the protocols that you have selected.
Enforce all protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client. By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use.
If a client attempts to use a restricted protocol anyway, MDaemon will still allow the connection. For your convenience, this option is mirrored on the global
339
screen. It is also an inheritable option on the
174
,
642
, and
647 settings screens. This makes it possible to restrict particular problem clients without restricting an entire class of clients.
4.9.1.3 Client Settings
This screen contains the global settings for managing ActiveSync clients. There are corresponding client settings under Mobile Device Management's
352
,
365
, and
358
screens for setting these options per domain, per account, and per client respectively. The global settings are set to specific values, but the domain,

account, and client settings are by default set to Inherit their settings from their respective parent options. Therefore changing any setting on this screen will effectively change the same setting on all child screens, allowing you by default to manage all clients on the server by changing only the settings on this one screen.
Conversely, changing a setting on a child screen will override its parent setting, allowing you to alter the settings at the domain, account, or client level if necessary.
Similar to
343
, which are assigned to the device and generally govern what the device can do, Client Settings govern what the server will do with regards to various client-related options, such as: governing how many separate ActiveSync clients an account can use, whether or not Public Folders will be synced to a device along with the account's personal folders, whether or not to include the user's whitelist folder, and so on.
Troubleshooting
Archive [XML | WBXML] requests and responses
Use the Archive XML... and WBXML options if you wish to save this data, which can sometimes be useful for debugging purposes. The global options are disabled by default.
Validate/correct PIM mrk file integrity
This option runs a validation and correction process on the client's PIM data to look for known issues that could prevent it from syncing correctly, such as duplicate iCal
UIDs or empty required fields. The global option is disabled by default.
Options
Create Tasks/Reminders for flagged mail items
This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.

Setup Menu 341
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway, MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.
New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.

Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e.
the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will be included. This option is disabled by default.
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

Require password
Check this box if you wish to require a password on the device. It is disabled by default.
Allow device to save 'Recovery Password' to server
Enable this option if you wish to allow clients to use ActiveSync's Recovery
Password option, which allows a device to save a temporary recovery password to the server to unlock the device if the password is forgotten. The administrator can find this recover password under the client's
358
. Most devices do not support this feature.
Password Type
Simple PIN
How this option is implemented is largely dependent on the device, but selecting Simple PIN as the password type generally means that no restrictions or complexity requirements are placed on the device password, other than the
Minimum password length option below. This allows simple passwords such as:
"111," "aaa," "1234," "ABCD" and the like.
Complex/Alpha-Numeric
Use this policy option if you wish to require more complex and secure device passwords than the Simple PIN option. Use the Complexity level option below to define exactly how complex the password must be. This is the default selection when a password is required by the policy.

Setup Menu 347
Password Strength
Minimum length
Use this option to set the minimum number of characters that the device password must contain, from 1-16. This option is set to "1" by default.
Complexity level
Use this option to set the complexity level requirement for Complex/Alpha-
numeric device passwords. The level is the number of different types of characters that the password must contain: uppercase letters, lowercase letters, numbers, and non-alphanumeric characters (such as punctuation or special characters). You can require from 1-4 character types. For example, if this option were set to "2", then the password must contain at least two of the four character types: uppercase and numbers, uppercase and lowercase, numbers and symbols, and so on. This option is set to "1" by default.
Password Options
Days until password expires (0=never)
This is the number of days allowed before the device's password must be changed. This option is disabled by default (set to "0").
Number of recent passwords remembered/disallowed by device (0=none)
Use this option if you wish to prevent the device from reusing a specified number of old passwords. For example, if this option is set to "2" and you change your device password, you will not be able to change it to either of the last two passwords that were used. The option is disabled by default (set to
"0").
Minutes of inactivity before device locks (0=never)
This is the number of minutes that a device can go without any user input before it will lock itself. This password option is disabled by default (set to "0").
Wipe device or enter 'Timed Lockout Mode' after repeated failed password attempts
When this option is enabled and the user fails the designated number of password attempts, the device will either lock itself for a certain amount of time or perform a wipe of all data, depending on the device. This option is disabled by default.
Failed password attempts before device wipes or enters 'Timed Lockout Mode'
When the "Wipe device.." option above is enabled and a user fails this many password attempts, the device will be wiped or the 'Timed Lockout Mode' will be triggered, depending on the device.

Enabling/Disabling ActiveSync for Specific Domains
To set the ActiveSync state for a specific domain:
1. Click a domain in the list.
2. Click Enable/Disable until the ActiveSync Enabled column shows the desired state. Choose Yes to enable ActiveSync, No to disable it, or Yes/No (Default) if you want the domain to use the default setting. The default setting is determined by the option: Enable all domains unless explicitly enabled or
disabled.
In order to use ActiveSync you will need to properly configure an ActiveSync client on the user's device. For instructions on how to do this, follow the

Setting the Default ActiveSync State
Domains with the ActiveSync Enabled column set to Yes/No (Default) get their
ActiveSync setting from state of the option: Enable all domains unless explicitly
enabled or disabled. When that option is enabled, all domains will have ActiveSync enabled by default. When it is disabled, ActiveSync will be disabled by default. Setting a domain specifically to Yes or No will override the default setting.

By default all of the options on this screen are set to "Inherit from parent," which means that each option will take its setting from the corresponding option on the
339
screen. Similarly, the client settings screens for this domain's

Settings screen is their parent screen. Any changes made to the options on this screen will be reflected on those screens. Below that, individual
358

This configuration makes it possible for you to make changes to all of a domain's accounts and clients simply by making changes to this one screen, while also making it possible for you to override those settings for any account or client as needed.
Troubleshooting
Archive [XML | WBXML] requests and responses
Use the Archive XML... and WBXML options if you wish to save this data, which can sometimes be useful for debugging purposes. The global options are disabled by default.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Validate/correct PIM mrk file integrity
This option runs a validation and correction process on the client's PIM data to look for known issues that could prevent it from syncing correctly, such as duplicate iCal
UIDs or empty required fields. The global option is disabled by default.
Options
Create Tasks/Reminders for flagged mail items
This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.
Allow search operations on...
Public Folders
Allows the client to search the
251
to which it has access. This is allowed by default.
Shared Folders
Allows the client to search the
629
to which it has access. This is allowed by default.
Send server based read receipts when requested.
Enable this option if you want the server to support read confirmation requests and issue a read receipt when a message is flagged as read by a client. This is disabled by default.
Request read receipts for all mail sent
Enable this option if you want the server to request read confirmation for all mail sent by a client. This is disabled by default.
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway,
MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail

using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.
New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.
Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e. the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will be included. This option is disabled by default.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 357
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

Removing an ActiveSync Device
To remove an ActiveSync device, select the device and click Remove. This will remove the device from the list and delete all synchronization information related to it in
MDaemon. Therefore if in the future the account uses ActiveSync to synchronize the same device, MDaemon will treat the device as if it had never before been used on the server; all device data will have to be re-synchronized with MDaemon.
Full Wiping an ActiveSync Client
To do a Full Wipe on an ActiveSync client or device, select the client from the list and click Wipe Client and then Wipe Client (Factory reset). The next time the client connects, MDaemon will tell it to erase all data, or restore itself to its factory default state. Depending on the client, this may remove everything on it, including downloaded apps. Further, as long as the client's ActiveSync entry exists in MDaemon, it will be wiped again if it ever connects again to MDaemon in the future. If you no longer wish to wipe the client when it connects (for example, if a lost device is recovered and you wish to use it again with the account) then you must first use the Remove option above to remove the client from MDaemon.
Account Wiping an ActiveSync Client
To wipe the account's mail and PIM data from the client or device, click Wipe Client and then Account Wipe (Account's Mail and PIM data only). The Account Wipe option is similar to the Full Wipe option explained above, but instead of wiping all data, it will wipe only the account's data, such as its emails, calendar entries, contacts, and the like. The rest, such as apps, photos or music is left alone.

1. Select an account from the list.
2. Click Assign Policy. This opens the Apply Policy dialog.
3. Click the Policy to Assign drop-down list and choose the desired policy.
4. Click OK.
This policy will be assigned to any new device that connects for this account.
Searching the List of Authorized Accounts
If you have a large number of accounts authorized to use ActiveSync, you can use the Find user box to search the list for a specific account. Simply type the first few letters of the account's email address to select the user.

Troubleshooting
Archive [XML | WBXML] requests and responses
Use the Archive XML... and WBXML options if you wish to save this data, which can sometimes be useful for debugging purposes. The global options are disabled by default.
Validate/correct PIM mrk file integrity
This option runs a validation and correction process on the client's PIM data to look for known issues that could prevent it from syncing correctly, such as duplicate iCal
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

UIDs or empty required fields. The global option is disabled by default.
Options
Create Tasks/Reminders for flagged mail items
This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.
Allow search operations on...
Public Folders
Allows the client to search the
251
to which it has access. This is allowed by default.
Shared Folders
Allows the client to search the
629
to which it has access. This is allowed by default.
Send server based read receipts when requested.
Enable this option if you want the server to support read confirmation requests and issue a read receipt when a message is flagged as read by a client. This is disabled by default.
Request read receipts for all mail sent
Enable this option if you want the server to request read confirmation for all mail sent by a client. This is disabled by default.
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway,
MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.

New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.
Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e. the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will be included. This option is disabled by default.
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 371
default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

Settings
Maximum folder monitoring timeout seconds (seconds)
This is the maximum amount of time that MDaemon ActiveSync Service (MDAS) will wait while monitoring a folder before returning a response to the client. The default value is 2700 seconds (i.e. 45 minutes).
Minimum folder monitoring timeout seconds (seconds)
This is the minimum amount of time that MDAS will wait while monitoring a folder before returning a response to the client. The default value is 120 seconds. If necessary you can reduce the number of connections that are made to the server by raising this value, since it would cause the client to connect less often due to the wait time involved being longer.
Maximum # of monitored folders
This is the maximum number of folders that each ActiveSync client is allowed to
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 377
monitor for changes. The default is 1024.
Folder monitor sleep timer (seconds)
This is the number of seconds that the ActiveSync service will wait between folder monitoring occurrences. This is set to 5 seconds by default.
Maximum item count per connection
This is the maximum number of items that the ActiveSync service will return to the client in response to a Sync request. Using a lower value in this option can reduce memory usage on a busy server, but it will require more connections and bandwidth.
It can also decrease battery life because devices may need to make more requests to get all changes during a sync. Higher values in this option increase memory usage and are more susceptible to communication errors. The default value of 100 is generally a good compromise. It is worth noting, however, that clients will specify the value that they prefer, which could effectively lower this value for some clients.
If a client requests a value greater than the maximum, then the maximum will be used.
Maximum XML response size (MB)
This is the maximum allowable size of a response to a Sync request from a client.
Prior to processing a given item for server-to-client synchronization, the current size of the response is checked and if it is greater than or equal to this value, the collection is flagged that there are more changes available, and we cease adding more items to the response. This is useful with servers that regularly contain a lot of large attachments in their email.
PIM Data cache expiration (minutes)
Since Contacts, Documents, Events, and other PIM data is often static, getting only occasional updates from clients, MDAS caches this data to reduce disk activity. It is, however, automatically reloaded whenever the data changes on disk. This value controls how long to cache the user's data since the last time it was accessed.
Public folder update interval (seconds)
This is the number of seconds MDAS will wait before updating Public Folders. The default interval is 60 seconds.
Remove inactive clients after [xx] days
This is the number of days that an
358
can go without connecting to MDAS before it will be removed. When the device is removed, its configuration and access settings are discarded. If the device ever connects again, MDaemon will respond as if it is a new device that has never been used on the server. It will be forced to reprovision if a policy is in place for the
352
or
365
, perform an initial folder sync, and re-sync all subscribed folders. This option can help keep your server free from maintaining information for old and unused devices. The option is set to 31 days by default.

4.9.2 BlackBerry Enterprise Server
MDaemon Pro is equipped with a BlackBerry Enterprise Server, which makes it possible for your users to synchronize their MDaemon/WorldClient email, calendar, and other personal information management (PIM) data with their BlackBerry smartphones.
BlackBerry platform support also makes it possible for you to set security polices for user devices and even erase a device should it be lost or stolen.
MDaemon's BlackBerry Enterprise Server features include:
No need for third-party sync clients. Each user's data is synchronized using software already present on all BlackBerry devices.
MDaemon/WorldClient email (including mail folders) is synchronized with the device in both directions. Therefore whether mail is read, moved, deleted, etc.
on the device or the server it will be synchronized on both.
Two-way Calendar synchronization. For example, if you create a new appointment, set a reminder, or modify an appointment on either the device or within WorldClient it will be synchronized in both places.
Two-way tasks and notes synchronization.
Global address book lookup.
Scheduling with free/busy.

BlackBerry Device Activation
In order to begin using MDaemon's BlackBerry Enterprise Server features an account must "activate" a BlackBerry device with MDaemon. To do this complete the following steps.
In MDaemon:
1. Go to: S etup » Black Berry... » Black Berry Enterpri s e S erv er » S tatus .
2. Click Enable BlackBerry Enterprise Server if it is not already enabled.
3. If you need to create a custom policy for the device, click
383
in the left pane to do so.
4. Click OK.
5. Go to: A ccounts » A ccount M anag er..., and double-click the account that you wish to allow to activate a device.
6. Click
637
in the left pane of the Account Editor.
7. Click Enable BlackBerry device synchronization.
8. Choose a policy from the drop-down list.
9. Click OK.
On the user's device:
1. Disable or remove any third-party sync clients (such as a SyncML client) currently in use to synchronize data with the MDaemon account.
2. If the device is configured to use the BlackBerry Internet Service (BIS) to get email from the account, go to the device's email setup and remove that account.
3. If there are any existing calendar entries on the device, you must either wipe the device or reset the calendar. Otherwise existing calendar data on the
MDaemon server may not be sent to the device. Always backup your device data before doing this. Note: if you choose to reset the calendar rather than wipe the device, the reset may be performed after activation. See
397
for more information.
Note: Failure to ensure that Steps 1 and 2 above are completed may result in duplicates of email, calendar entries, or other PIM data on the device.

Setup Menu 381
In WorldClient, the user must:
1. Log in to WorldClient.
2. Go to: Opti ons » Black Berry M anag ement.
3. Connect the device via a USB cable and follow the directions on the screen
(requires Internet Explorer 6 or later).
-or-
Enter an activation password, click Save, and then activate the device overthe-air (OTA) directly from the device's Enterprise Activation screen — the user will enter the account's email address and activation password on the device.
Note: Not all devices support OTA activation.
4. Sign out from WorldClient.
After initiating the activation process, whether via USB cable or OTA, it will continue on the device until finished. When the activation process is complete it will be paired with the MDaemon/WorldClient account. Within a short time data will begin to synchronize.
Depending on the device and operating system installed, activation may delete all data on the device, restoring it to its default settings before synchronizing it with MDaemon/
WorldClient. For this reason, before activating the device the user should use Desktop Manager or some other means to backup or export any data that he or she does not wish to lose.
After a device is activated it may have various functionality changes or operating differences when compared to its state prior to BlackBerry Device Activation. The degree of difference depends on the device, OS, policy used, and whether or not it was previously activated on a different BlackBerry Enterprise
Server.

4.9.2.2 Policies
Setup Menu 383
When a BlackBerry device is activated on MDaemon, a designated policy is pushed to that device. Policies are sets of rules that govern what is required or permitted on a device. They allow you to do things like require passwords, force the device to lock when holstered, encrypt files on the device, and more. Policies can be assigned to domains and to individual accounts. Use the
390
screen to assign policies to domains, or use the
637
screen on the Account Editor to assign them to specific accounts. MDaemon is equipped with three pre-configured policies, and you can create your own custom policies.
After a device is activated it may have various functionality changes or operating differences when compared to its state prior to BlackBerry Device Activation. The degree of difference
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
384 MDaemon Messaging Server 17.0
depends on the device, OS, policy used, and whether or not it was previously activated on a different BlackBerry Enterprise
Server.
Pre-configured Policies
There are three pre-configured policies that cannot be edited or removed:
Default
This policy causes the BlackBerry device to use standard BlackBerry Enterprise
Server defaults for all settings. This is a standard "out-of-the-box" and "under the control of a BlackBerry Enterprise Server" policy configuration.
Password Required
This policy is like Default except that it sets the Password Required rule to YES and the User can disable password rule to No (see rule descriptions below). Devices with this policy must be secured by a password.
Expiring Passwords
This policy is like Password Required but also sets the Max password age (days) rule to 30. The password on the device will have to be changed at least every 30 days.
Creating a Custom Policy
To create a custom policy:
1. Click New.
2. Enter a name for the policy.
3. Click OK.
4. Set the various policy rules as desired.
5. Click Save.
Policy Rules
The following is a list of all policy rules that you can set when creating or editing a custom policy.
Password Settings
Contains policy rules that apply to BlackBerry device password settings.
Password required
Specify whether the BlackBerry device requires a password. Set this rule to
YES to require the user to enter a password to unlock the BlackBerry device.
Rule dependency: If you enable this rule, you should set the User can disable
password rule to NO to prevent the BlackBerry device user from disabling this
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 385
rule.
Minimum password length
Type the minimum required length, in characters, of the BlackBerry device password. This rule only controls the minimum password length, not the maximum password length. The maximum password length is 32 characters.
The valid range for the value of this rule is 4 through 14.
Rule dependency: The BlackBerry device uses this rule only if a BlackBerry device password is set. To require a BlackBerry device password, set the
Password required rule to YES.
User can disable password
Specify whether the user can disable the requirement for a BlackBerry device password. Set this rule to NO to prevent users from disabling the password requirement on the BlackBerry device.
Rule dependency: The BlackBerry device uses this rule only if a BlackBerry device password is set. To require a BlackBerry device password, set the
Password required rule to YES.
Max security timeout (minutes)
Specify the maximum time, in minutes, that a BlackBerry device user can set as the security timeout value (the number of minutes of BlackBerry device user inactivity allowed before the security timeout occurs and the device requires the user to type the BlackBerry device password to unlock it). The BlackBerry device user can set any timeout value that is less than or equal to the maximum value, unless you set the User can change timeout rule value to NO.
The maximum security timeout value available by default on the BlackBerry device is 60 minutes. The valid range for the value of this rule is 10-480 minutes.
Note: Use the Set Password Timeout (minutes) rule if you wish to set a specific timeout value.
Rule dependency: The BlackBerry device uses this policy rule only if the
Password required rule is set to YES.
User can change timeout
Specify whether the BlackBerry device user can change the security timeout.
If set to YES, the user can set the timeout to any available value up to the limit set in the Max security timeout (minutes) rule. Set this rule to NO if you wish to prevent the user from changing the timeout value. If no value is set then a default value of YES is used.
Max password age (days)
Type the number of days until a BlackBerry device password expires and the
BlackBerry device prompts the user to set a new password. The valid range for the value of this rule is 0-65535 days. Note: Set this rule to 0 to prevent the
BlackBerry device password from expiring.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
386 MDaemon Messaging Server 17.0
Rule dependency: The BlackBerry device uses this rule only if a BlackBerry device password is set. To require a BlackBerry device password, set the
Password required rule to YES.
Set password timeout (minutes)
Specify the amount of time, in minutes, of BlackBerry device user inactivity allowed before the security timeout occurs and the BlackBerry device requires the user to type the password to unlock the BlackBerry device. The valid range for the value of this rule is 0-60.
Note: The default security timeout interval is 2 minutes of inactivity for
BlackBerry device software versions earlier than 4.7, and 30 minutes of inactivity for BlackBerry device software versions 4.7 and later.
Rule dependencies: The BlackBerry device uses this rule only if the Password
required rule is set to YES. If you do not set the User can change timeout rule to NO, the BlackBerry device user can set the password timeout to one of a range of values. The maximum security timeout value available by default on the BlackBerry device is 60 minutes.
Set max password attempts
Set the number of password attempts (incorrect passwords entered) permitted on the BlackBerry device before the BlackBerry device data is erased and the
BlackBerry device is disabled. The valid range for the value of this rule is 3-10 attempts. 10 attempts are allowed by default.
Rule dependency: The BlackBerry device uses this rule only if a BlackBerry device password is set. To require a BlackBerry device password, set the
Password required rule to YES.
Suppress password echo
Set this rule to YES to prevent the echoing (printing to the screen) of characters typed into the password screen after the user has entered a set number of incorrect passwords while attempting to unlock the device.
Note: You can use the Set max password attempts rule to designate the number of incorrect password attempts allowed before password echoing occur
(if permitted).

Content protection
Specify whether content protection is turned on.
When content protection is turned on, BlackBerry device content is always protected with the 256 bit AES encryption algorithm. If the BlackBerry device is locked when it receives content, the BlackBerry device randomly generates the content protection key (a 256 bit AES encryption key) and an ECC key pair, derives an ephemeral 256 bit AES encryption key from the BlackBerry device password, and uses the ephemeral key to encrypt the content protection key and the ECC private key.
Rule dependency: The BlackBerry device uses this policy rule only if the
Password required rule is set to YES.
External file system encryption level
Specify the level of file system encryption that the BlackBerry device uses to encrypt files that it stores on an external file system. You can use this policy rule to require the BlackBerry device to encrypt an external file system, either including or excluding multimedia directories. If you do not set this rule, a default value of Level 0 (i.e. Not Required) will be used.
You can set this rule to the following values:
Level 0: Not Required
Level 1: Encrypt to User Password (excluding multi-media directories)

Encryption on on-board device media files
Specify whether the media files located on the on-board device memory will be encrypted to the user password and the device generated key if on-board device memory exists. If you set this rule to Required or Disallowed the user cannot change this setting on the device. If you do not set this rule, a default value of Allowed will be used.
Rule dependency: The BlackBerry device uses this policy rule only if the
Content protection strength is set.
Password required for application download
Specify whether the BlackBerry device will prompt the user for their password prior to using the browser to download applications.
Rule dependency: The BlackBerry device uses this rule only if a BlackBerry device password is set. To require a BlackBerry device password, set the

Logging Settings
There are two BlackBerry logging options: MDaemon agent logging and BlackBerry
Enterprise Server component logging. You can enable/disable them separately and set the level of logging detail that will be maintained for each. There are four levels of logging detail to choose from: Error, Warning, Informational, and Debug. Error is the lowest level of logging and Debug is the highest, which should generally be used only when diagnosing a problem. Informational maintains a good level of detail and is the default setting for both options. Click Defaults to restore the logging levels to the default settings.
Whenever you change the logging level the BlackBerry
Enterprise Server services will be restarted.
The BlackBerry log files use MDaemon's global
145
settings for size and roll-over but are slightly different in format than other MDaemon logs. The logs are stored in the
\Logs\BES\
subfolder.
Synchronization
When a device is activated...
These option are used to ensure that when a BlackBerry device is first activated, some of its old mail (mail sent or received prior to activation) will be synchronized with the device rather than only new mail. All mail processed for the account between the time it was
enabled for BlackBerry device synchronization
637
and the device was activated will be synchronized with the device. If the number of messages or number of days worth of messages specified below have not been exceeded by the initial synch, then more mail will be synchronized according to the options.
...send this many days worth of old messages to the BlackBerry
Use this option to set the minimum number of days worth of old messages to send to the device when it is first activated. If it is set to 5, for example, then at least the last five days worth of messages will be sent.
This setting is also used during resynchronization (
392
). Slow sync will only add messages missing from the database
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Setup Menu 397
if they are more recent than the number of days specified here.
...send this many old messages to the BlackBerry
Use this option to set the number of old messages to synchronize with the device when it is first activated. This option takes precedence over the "...send
this many days worth of old messages" option above, and the initial synchronization after activation may exceed this number of messages if more than that are processed between the time the account is enabled for BlackBerry device synchronization and when the device is activated. This option is set to
200 by default.
...send message headers only
Use this option to send only the message headers to the device rather than the entire message when old messages are synchronized.
Calendar syncs only...
These options determine the number of calendar events that will be synchronized with activated BlackBerry devices. Whenever these values are changed, a
392
must be performed in order for any events that would be affected by the change to be added or deleted from the devices. A calendar slow sync occurs automatically every night at midnight.
...send this many days worth of old events to the BlackBerry
This is the number of days worth of past calendar events that will be synchronized with the BlackBerry device calendar. Recurring events older than this number of days will still appear on the device calendar if one of the event's occurrences lies within the designated limit.
...send this many days worth of future events to the BlackBerry
This is the number of days worth of future events that will be synchronized with the BlackBerry device.
If there are any existing calendar entries on the device before it is activated, you must either wipe the device or reset the calendar. Otherwise existing calendar data on the MDaemon server may not be sent to the device. If you choose to reset the calendar rather than wipe the device, the reset may be performed after activation. See Resetting the Device
Calendar below for more information. Always backup your device data before erasing it or resetting the calendar.

4.9.3 BlackBerry Internet Service
MDaemon is equipped with direct support for the BlackBerry Internet Service (BIS).
BlackBerry Internet Service users can integrate their MDaemon mail account with their
BlackBerry smartphone, allowing for BlackBerry push mail as well as improved email handling when using a BlackBerry device with MDaemon. Any BlackBerry device set up to pull mail from MDaemon via IMAP or POP prior to MDaemon version 11.0 can now be set up for push mail instead. Further, messages that are composed on the device will be sent to your MDaemon for delivery rather than having the BlackBerry Internet
Service servers deliver them. This allows emails composed on a BlackBerry device to comply with your server's security policies, content-filter rules, DKIM, archiving, and so on.
Since the BlackBerry Internet Service only collects mail from a user's Inbox, this can cause problems for people who use
623
to sort their messages to specific folders automatically. To overcome this problem, the
640
screen of the
Account Editor and the Folders page in WorldClient allow the administrators and users, respectively, to choose which folders' new messages will be delivered to the user's device. When the BlackBerry Internet Service connects to MDaemon to collect new
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
400 MDaemon Messaging Server 17.0
messages from the user's Inbox, MDaemon will also push the new messages from the selected folders. All new messages from all the selected folders will be sent to the
BlackBerry device's Inbox. This does not push the actual folders to the device, it pushes only the new messages that they contain.
Finally, an internal folder aliasing scheme allows each user's "Sent Items" and "Deleted
Items" folders to appear as values that the BlackBerry Internet Service recognizes, no matter what those folders are actually called in the user's account. This helps ensure that sent and deleted messages are placed into the proper MDaemon folders.
The BlackBerry Internet Service section of the BlackBerry dialog contains the following screens:
401
— use this screen to enable BlackBerry Internet Service integration for whichever domains you choose. There are options for entering the Subscribe URL and the SMTP server to which the BlackBerry Internet Service should pass messages when they are composed on a BlackBerry device. There is a history text box on the bottom of the screen that lists your BlackBerry Internet Service subscribe/unsubscribe activity, and there are several SSL and STARTTLS related options.
403
— this screen lists the subscription numbers of all MDaemon accounts that are setup for BlackBerry Internet Service push mail and are thus integrated directly with MDaemon. Even if an account is not listed as an integrated account, a BlackBerry Internet Service server may still be able to collect mail on behalf of the BlackBerry device via POP3 or IMAP, but it will not have the advantage of being able to send messages through your MDaemon server.
406
— this screen has several global options governing MDaemon's
BlackBerry integration features. For example, you can choose whether or not to allow MDaemon to push mail from non-Inbox folders, you can choose to apply
298
to Devices, you can allow multiple devices to integrate with a single MDaemon account, and several other options.
MDaemon requires all IMAP/POP sessions from BlackBerry
Internet Service users to use a full email address when logging in to MDaemon. Thus when configuring their BlackBerry devices to collect mail they will need to use the full email address as the login parameter instead of just the mailbox portion of the address. This is necessary in order to avoid possible conflicts and to achieve proper account integration. This might mean that some of your existing users will have to delete and recreate the mail profile on their device, or at least change their login value to the full address.

This is the WorldClient URL to which the BlackBerry Internet Service will send subscribe and unsubscribe requests. When a user adds his MDaemon email account to his BlackBerry device, the BlackBerry Internet Service will send a subscribe request to this URL within approximately twenty minutes. MDaemon will then add the account to the
403
screen. Subscription requests are managed by
WorldClient, therefore WorldClient must be active.
When using IIS rather than WorldClient's native web server, you must add MDbis.dll (located in MDaemon\Worldclient

) to IIS in order for incoming SUBSCRIBE commands to be processed properly.
SMTP Server/port
This is the SMTP server and port to which all email composed on the integrated account's device will be sent for delivery.

in MDaemon, check this box if you want the
BlackBerry Internet Service SMTP client to use the dedicated SSL port.
The BlackBerry Internet Service SMTP client does not support
SSL with self-signed certificates. Therefore if you wish to use
SSL then you must use a commercial, third-party certificate.

Configuring Accounts to Push Mail to a BlackBerry Smartphone
The Subscribers screen lists all of your MDaemon accounts that are configured to push mail to a BlackBerry smartphone. To setup a new account for push mail:
1. Enable the BlackBerry Internet Service integration options for the server and domain on the
401
screen, and make sure that the Subscribe URL and
SMTP server value are pointing to WorldClient and your MDaemon server, respectively.
2. If the BlackBerry smartphone is already collecting mail from the user's
MDaemon account, because the account was added to the device prior to activating MDaemon's BlackBerry Internet Service features, then delete that email account from the device. In the next step you will need to recreate the account on the device so that you can trigger push mail setup within the
BlackBerry Internet Service.
3. Add the MDaemon email account to the user's BlackBerry smartphone, using the full email address and password as its login credentials. For detailed instructions on how to add an email account to a BlackBerry smartphone, see the device's online help or documentaion. You must only add the account in this step, not edit it. After creating the account, do not edit its signature, name settings, advanced options, or the like. You can make changes to the account later, in step 6.
4. Shortly after the account is added to the device, the Subscribe URL associated with the user's domain will receive a SUBSCRIBE request from the
BlackBerry Internet Service service. This incoming request will be processed by WorldClient and the subscribed account will appear in the Subscribers list.
The SUBSCRIBE request usually takes about 5 minutes to arrive, but can take up to 20.
5. Almost immediately after adding the account to the device it should receive an "Email activation information" email. Then, once the SUBSCRIBE request is properly received and processed, the BlackBerry device will receive a second email: "Email activation information (push mail)." Once that second email is received you know that the account has been successfully configured for push mail in MDaemon.
6. Make any desired changes to the email account on the device. You can add a signature, edit the name, adjust the advanced settings, and so on.
While waiting for the SUBSCRIBE request from the BlackBerry
Internet Service to arrive, any changes to the email account on the device (such as signature text, advanced setup options, etc) will invalidate the request and you will not receive it. Therefore you must make no changes to the account on the device until the SUBSCRIBE request arrives.
Otherwise you will need to delete the account and recreate it in order to restart the SUBSCRIBE process.

This level of integration is not possible using POP. Any of your
BlackBerry users currently using POP to collect mail will need to delete their email profile and recreate it using IMAP (not POP) which may require accessing advanced setup options on the
BlackBerry. Consequently, MDaemon's IMAP server must be running for this feature to work.
Unsubscribing an Integrated Account
Unsubscribing from push mail can be done by deleting the email profile using the
BlackBerry device itself. The BlackBerry Internet Service will then send MDaemon an
UNSUBSCRIBE request and the account will be unlinked. The UNSUBSCRIBE request may take some time to arrive and this poses no operational issues.

BlackBerry Internet Service Integration Settings
Enable selection of non-Inbox folders
By default in MDaemon, messages placed in non-Inbox IMAP folders can be pushed to a BlackBerry smartphone's Inbox. This is managed through the
screen of the Account Editor and the Folders page in WorldClient. These screens
640 allow the administrators and users, respectively, to choose which folders' new messages will be delivered to the user's device. If you do not wish to allow users with a BlackBerry device to collect mail from any of their IMAP folders other than the
Inbox, then disable this option. However, we recommend that you leave this option enabled, because if you disable it then those who use
623
to sort their messages into specific folders will not be able to get those filtered messages on their device.
This feature operates independently from the account integration options on the
401
and
403 screens. Even if you disable BlackBerry Internet Service integration in MDaemon, a user can still create an email account on his BlackBerry device to collect his mail from

MDaemon, just as he can collect it using any other traditional email client or smartphone. This feature simply makes it possible for BlackBerry smartphone users to collect messages from the folders that they are using IMAP filters to manage.
Enable Sent/Deleted folder aliasing
By default an internal folder aliasing scheme allows each user's "Sent Items" and
"Deleted Items" folders to appear as values that the BlackBerry Internet Service recognizes, no matter what those folders are actually called in the user's account.
This doesn't alter any folder names in any way. It is entirely an internal aliasing function to help ensure that sent and deleted messages are placed into the proper
MDaemon folders. As with the above option, this option operates independently from the account integration options. It can be used even if the Enable BlackBerry
Internet Service integration option is disabled on the Domains screen. If you do not wish to alias these folders for BlackBerry users, disable this option.
Users can designate the folders they wish to use as their Sent
Items and Deleted Items folders from the Folders page in
WorldClient.

4.9.4 SyncML
WorldClient includes a SyncML server that can be used to synchronize your Contacts,
Tasks, and Calendar events with any SyncML capable mobile devices. If your
BlackBerry smartphone or other device doesn't have built-in SyncML support then you must install a third-party synchronization client on it. Some example clients are:
Funambol Sync Client, Synthesis, and SyncJE. There are also sync clients available for synchronizing your calendar with an email client such as Microsoft Outlook. The
Funambol Sync Client, for example, is available for Outlook, BlackBerry, Windows Mobile, and other types of applications and devices. Several clients are available free of charge.
For more information on SyncML and the SyncML specification, visit the Open Mobile
Alliance (OMA) .
SyncML
Select domain
Use this drop-down list box to choose the domain you wish to configure. After selecting the domain, check or uncheck the "Enable SyncML server" box and then click
Apply
or
OK
to save the setting. Choose "Default" from the drop-down list to designate the default setting. The default setting will be applied to all new domains and all existing domain for which you have not specifically defined a SyncML setting.

Enable SyncML server
Enable or disable this option to designate whether or not the SyncML server will be accessible by the domain selected in the Select domain option above.
SyncML sessions time out after XX inactive minutes
This is the length of time a SyncML session will be permitted to remain inactive before it will time out and be closed. This is a global setting—it applies to all SyncML sessions regardless of the domain.
SyncML log level
Use this drop-down list to designate the degree to which SyncML activities will be logged. There are six possible levels of logging: 1-Debug logging, 2-Normal logging,
3-Warnings and errors only, 4-Errors only, 5-Critical errors only, and 6-No logging.
This is a global setting—it cannot be applied to specific domains.
4.9.4.1 Configuring Your SyncML Clients
In order to access WorldClient
' s SyncML server, your SyncML clients must be configured to connect to: http://<WorldClient Server><:port>/MDSyncML.dll
Examples: http://mail.example.com:3000/MDSyncML.dll
http://www.example.com/MDSyncML.dll
If your SyncML client asks for folder names, use
Contacts
,
Calendar
, and
Tasks
.
Those names always expand to the user
' s default WorldClient folders of the corresponding type.
The SyncML server supports any of the following formats for the folder paths: contacts
/contacts
./contacts contacts/phone
(assuming a phone sub-folder exists) contacts.imap\phone.imap
Before attempting to synchronize using SyncML, a user must log in to WorldClient one time.

MDaemon system account mailbox alias [address]
This is the email address from which system generated messages will come.
Subscription confirmations, delivery status notification (DSN) messages, various other notification messages, and the like are all system messages.
Default attachment extension
System generated messages will be created using this extension. This will also be the extension assigned to attachments included with system generated messages.
For example, if MDaemon generates a warning message to the postmaster about a specific message it will attach that message with this value as the file extension.
Default logon delimiter character (10 characters max)
When using an email address as the account logon parameter, this character or string of characters can be used as an alternative to "@". This may be necessary for some users that have email clients which do not support "@" in the logon field. For example, if you used "$" in this field then users could login using
"[email protected]" or "user1$example.com".
Servers require full email address for authentication
MDaemon's POP and IMAP servers require you to use your full email address by default when logging in to MDaemon. If you wish to allow mailbox only logins (e.g.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

4.10.1.4 Fixes
Remove CRLFCRLF from the end of message bodies
Certain mail clients have problems displaying messages that end with consecutive
Carriage Return Line Feeds (i.e. CRLFCRLF). When this box is checked, MDaemon will strip consecutive
CRLFCRLF
sequences from the end of the message body. This option is enabled by default.
Remove CRLF LF.CR CRCRLF from the end of message bodies
By default, MDaemon will remove this sequence from the end of messages, as it can cause problems for some mail clients. Uncheck this box if you do not wish to remove this sequence from messages.
Remove NULL & EOF but allow LF.LF at the end of message bodies
When this box is checked MDaemon will remove
Null
and EOF characters from the end of message bodies, but it will allow messages ending in
LF.LF
, as well as messages ending with the normal
CRLF.CRLF
sequence that signifies the end of a message. This option is enabled by default.
Prefix illegal headers with "X-MD-Bad-Header:"
When this option is enabled and MDaemon encounters a bad message header, it will prefix the bad header with "
X-MD-Bad-Header:
" This option is enabled by default.
Copy 'Sender:' to 'From:' when 'From:' is missing
Some mail clients fail to create a
FROM:
header when you compose a message.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
418 MDaemon Messaging Server 17.0
Instead, the
FROM:
header's information is placed in the
Sender:
header. This can cause problems for some mail servers as well as the recipient of your message. To help prevent these problems, MDaemon will create the missing
FROM:
header by using the contents of the
Sender:
header when this box is checked. This option is enabled by default.
Accept message even if connection drops after DATA
When this option is enabled, MDaemon will accept and deliver a message even if there's a connection abort during or immediately after the DATA command during the
SMTP process. This should not be used under normal circumstances as it can lead to duplicate messages.
4.10.1.5 Headers
If missing, insert these headers
Date
When a message is encountered that doesn't have a "
Date:
" header, MDaemon will create one and add it to the message file if this option is enabled. It will be the date on which MDaemon first receives the message, not when it was created by the sender. There are some mail clients that do not create this header, and since some mail servers refuse to honor such messages, this feature will enable them to be delivered.

All other headers starting with X-
MDaemon and other mail servers use many server specific headers called
X-Type headers in order to route mail and perform various other functions. When this option is enabled, MDaemon will strip these headers from messages.
Note:
this option does not remove
X-RBL-Warning
headers. If you wish to remove those headers, use the "X-RBL-Warning" option above.
Add these headers
Precedence: bulk (system generated mail 'From: MDaemon' only)
When this box is checked all system generated messages from MDaemon (welcome messages, warnings, "could not deliver" messages, and so on) will have a
"Precedence: bulk" header inserted.
X-Authenticated-Sender: (authenticated mail only)
By default MDaemon will add the "X-Authenticated-Sender:" header to messages that arrive on an authenticated session using the
AUTH
command. Uncheck this box if you do not wish to add this header.
Content-ID: (RAW messages with attachments)
Check this box if you wish to add unique MIME
Content-ID
headers to messages that MDaemon creates from a RAW file that contains attachments.
Hide reserved IPs when creating message headers
This option is enabled by default and prevents reserved IP addresses from appearing in certain MDaemon created message headers. Reserved IP addresses include:
127.0.0.*
, 192.168.*.*, 10.*.*.*, and 172.16.0.0/12. If you also wish to hide your domain IPs (including LAN domains) from the headers then you can set the following switch in MDaemon's app\MDaemon.ini file manually: [Special]

5 Security Menu
MDaemon is equipped with an extensive suite of security features and controls. Click
S ecuri ty
on MDaemon
' s menu bar to reach the following security features:
430
— MDaemon Private Cloud's AntiVirus features can help you stop email-borne computer viruses by providing the highest level of integrated protection available for MDaemon customers. They will catch, quarantine, repair, and/or remove any email message found to contain any virus. The
456
component can be used to protect you from certain spam, phishing, and virus outbreaks that can sometimes be missed by the other traditional, content and signature-based security measures.
431
— a highly versatile and fully multi-threaded Content Filtering system makes it possible for you to customize server behavior based on the content of incoming and outgoing email messages. You can insert and delete message headers, add footers to messages, remove attachments, route copies to other users, cause an instant message to be sent to someone, run other programs, and much more.
473
— uses spam filtering technology to heuristically examine email messages in order to compute a "score". This score is used to determine the likelihood of a message being spam. Based on that determination the server can then take certain actions such as refusing or flagging the message. See also:
504
497
—allows you to specify several DNS blacklisting services that will be checked each time someone tries to send a message to your server. If the connecting IP has been blacklisted by any one of these hosts, the message will be refused.
505
— used to control what MDaemon will do when a message arrives at your mail server that is neither from nor to a local address.
513
— if a domain name specified in this list attempts to connect to your server, its IP address must match the one that you have assigned to it.
507
— MDaemon can query DNS servers to check the validity of the domain names and addresses reported during incoming messages. Controls on this screen can be used to cause suspicious messages to be refused or a special header inserted into them. Reverse Lookup data will also be reported in the MDaemon logs.
510
— the controls on this screen are used to require each user to first access his or her mailbox before being allowed to send a message through MDaemon, thus authenticating that the user is a valid account holder and allowed to use the mail system.
511
— domain names and IP addresses that will be considered as exceptions to the relay rules listed on the Relay Control screen.
515
— used for setting several options that denote how
MDaemon will behave when a user sending a message to MDaemon has or has not been authenticated first.
517
— Most domains publish MX records to identify the machines that may
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 429
receive mail for them, but this doesn't identify the locations allowed to send mail for them. Sender Policy Framework (SPF) is a means by which domains can also publish "reverse MX" records to identify those locations authorized to send messages.
519
— DomainKeys Identified Mail (DKIM) is an email verification system that can be utilized to prevent spoofing. It can also be used to ensure the integrity of incoming messages, ensuring that the message hasn't been tampered with between the time it left the sender's mail server and arrived at yours. This is accomplished by using an encrypted public/private key pairs system. Outgoing messages are signed using a private key and incoming messages have their signatures verified by testing them with the public key published on the sender's DNS server.
541
— Message Certification is a process by which one entity vouches for or "certifies" the good email conduct of another entity. The
Certification feature is beneficial because it can help ensure that messages will not be erroneously or needlessly subjected to unwarranted spam filter analysis.
It can also help lower the resources required to process each message.
547
— lists addresses that are not allowed to send mail traffic through your server.
550
— used to designate IP addresses from which you will allow or refuse connections to your server.
553
— used to designate hosts (domain names) from which you will allow or refuse connections to your server.

— using the Dynamic Screening feature, MDaemon can track the behavior of sending servers to identify suspicious activity and then respond accordingly. For example, you can temporarily ban an IP address from future connections to your server once a specified number of "unknown recipient" errors occur during the mail connection from that IP address.

— "Backscatter" refers to response messages that your users receive to emails that they never sent. This occurs when spam messages or messages sent by viruses contain a Return-Path address that is forged. Backscatter Protection helps prevent this by ensuring that only legitimate Delivery Status Notifications and Autoresponders get delivered to your accounts, by using a private key hashing method to generate and insert a special time-sensitive code into the Return-Path address of your users' outgoing messages.

— Greylisting is a spam-fighting technique that exploits the fact that SMTP servers retry delivery of any message that receives a temporary (i.e.
"try again later") error code. Using this technique, when a message arrives from a non-white listed or otherwise previously unknown sender, its sender, recipient, and sending server's IP address will be logged and then the message will be refused by Greylisting with a temporary error code during the SMTP session.
Then, when the legitimate servers attempt to deliver the messages again a few minutes later, they will be accepted. Because spammers do not typically make further delivery attempts, Greylisting can significantly help to reduce the amount of spam your users receive.

5.1 Content Filter and AntiVirus
Content Filter
The
431
(S ecuri ty » Content Fi lter) can be used for a large number of purposes such as: preventing spam email, intercepting messages containing viruses before they reach their final destination, copying certain emails to one or more additional users, appending a note or disclaimer to the bottom of messages, adding, and deleting headers, stripping email attachments, deleting messages, and more.
Because individual Content Filter rules are created by the administrator, and because of their diversity, they can be used in many situations and are limited for the most part only be the creativity of the person creating them. With a little bit of thought and experimentation, this feature can be very useful.
MDaemon Private Cloud's AntiVirus Features
When utilizing MDPC's optional AntiVirus component, you will have access to the

AntiVirus features and designate what actions MDaemon will take when a virus is detected. You will also have access to

All messages processed by MDaemon will at some point reside temporarily in one of the message queues. When Content Filtering is enabled, before any message is allowed to leave the queue it will first be processed through the Content Filter rules. The result of this procedure will determine what is done with the message.

Messages that have a filename beginning with the letter "P" will be ignored by the content filtering process. Every other message will be processed through the content filter system.
Once processed, MDaemon will change the first character of the filename to a "P". In this way a message will only be processed through the content filtering system once.
Content Filtering Rules
Enable rules processing engine
Click this checkbox to enable content filtering. All messages processed by MDaemon will be filtered through the content filter rules before being delivered.
Existing Content Filtering Rules
This box lists all of your Content Filter rules, with a checkbox beside each one so that you can enable/disable them at will. To see a description of any given rule in its internal script format, click that rule and pause your mouse-cursor over it (moving your mouse will cause the description to disappear). Whenever a message is processed through the Content Filter, these rules will be applied in the order in which they are listed. This makes it possible for you to arrange your rules to achieve a greater level of versatility.
For example: If you have a rule that deletes all messages containing the words,
"This is Spam!" and a similar rule that sends those messages to the Postmaster, then putting them in the right order will enable both rules to be applied to the message.
This assumes that there isn
' t a "Stop Processing Rules" rule that applies to the message higher up in the list. If so, then you would use the
Move Up
/
Move Down
buttons to move the "Stop" rule below the other two. Then, any message containing
"This is Spam!" would be copied to the Postmaster and then deleted.
MDaemon has the capability to create rules that will perform multiple tasks and use and/or logic. Considering the example above, instead of using multiple rules you could create a single rule that would accomplish all of those tasks and more.

5.1.1.1.3 Using Regular Expressions in Your Filter Rules
The Content Filtering system supports regular expression searches, which is a versatile system that makes it possible for you to search not only for specific text strings, but also for text patterns. Regular expressions contain a mix of plain text and special characters that indicate what kind of matching to do, and can thus make your Content
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
438 MDaemon Messaging Server 17.0
Filter rules more powerful and better targeted.
What are Regular Expressions?
A regular expression (regexp) is a text pattern consisting of a combination of special characters known as
metacharacters
and alphanumeric text characters, or "
literals
" (abc,
123, and so on). The pattern is used to match against text strings—with the result of the match being either successful or not. Regexps are used primarily for regular text matches and for search and replace.
Metacharacters are special characters that have specific functions and uses within regular expressions. The regexp implementation within the MDaemon Content Filtering system allows the following metacharacters:
\ | () [] ^ $ * + ? . <>
Metacharacter
\
|
[...]
^
[^...]
(...)
Description
When used before a metacharacter, the backslash ( "\" ) causes the metacharacter to be treated as a literal character. This is necessary if you want the regular expression to search for one of the special characters that are used as metacharacters. For example, to search for "+" your expressions must include "\+".
The alternation character (also called "or" or "bar") is used when you want either expression on the side of the character to match the target string. The regexp "abc|xyz" will match any occurrence of either "abc" or "xyz" when searching a text string.
A set of characters contained in brackets ("[" and "]") means that any character in the set may match the searched text string. A dash ("-") between characters in the brackets denotes a range of characters. For example, searching the string "abc" with the regexp "[a-z]" will yield three matches: "a," "b, " and "c. " Using the expression
"[az]" will yield only one match: "a."
Denotes the beginning of the line. In the target string, "abc ab a" the expression "^a" will yield one match—the first character in the target string. The regexp "^ab" will also yield one match—the first two characters in the target string.
The caret ("^") immediately following the left-bracket ("[") has a different meaning. It is used to exclude the remaining characters within brackets from matching the target string.
The expression "[^0-9]" indicates that the target character should not be a digit.
The parenthesis affects the order of pattern evaluation, and also serves as a tagged expression that can be used in
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 439
$
*
+
?
.
search and replace expressions.
The results of a search with a regular expression are kept temporarily and can be used in the replace expression to build a new expression. In the replace expression, you can include a "$0" character, which will be replaced by the substring found by the regular expression during the search.
So, if the search expression "a(bcd)e" finds a sub-string match, then a replace expression of "123-$0-123" will replace the matched text with "123-abcde-123".
Similarly, you can also use the special characters "$1,"
"$2," "$3," and so on in the replace expression. These characters will be replaced only be the results of the tagged expression instead of the entire sub-string match. The number following the backslash denotes which tagged expression you wish to reference (in the case of a regexp containing more than one tagged expression). For example, if your search expression is "(123)(456)" and your replace expression is "a-$2-b-$1" then a matching sub-string will be replaced with "a-456-b-123" whereas a replace expression of "a-$0-b" will be replaced with "a-123456-b"
The dollar sign ("$") denotes the end of the line. In the text string, "13 321 123" the expression "3$" will yield one match
—the last character in the string. The regexp "123$" will also yield one match—the last three characters in the target string.
The asterisk ("*") quantifier indicates that the character to its left must match zero or more occurrences of the character in a row. Thus, "1*abc" will match the text
"111abc" and "abc."
Similar to the asterisk quantifier, the "+" quantifier indicates that the character to its left must match one or more occurrences of the character in a row. Thus, "1+abc" will match the text "111abc" but not "abc."
The question mark ("?") quantifier indicates that the character to its left must match zero or one times.
Thus, "1?abc" will match the text "abc," and it will match the "1abc" portion of "111abc."
The period or dot (".") metacharacter will match any other character. Thus ".+abc" will match "123456abc," and "a.c" will match "aac," abc," acc," and so on.
Eligible Conditions and Actions
Regular expressions may be used in any

Configuring a Regexp in a Rule's Condition
To configure a header or message body condition to use a regular expression:
1. On the Create Rule dialog, click the checkbox that corresponds to the header or message body condition that you wish to insert into your rule.
2. In the summary area at the bottom of the Create Rule dialog, click the "
contains specific strings
" link that corresponds to the condition that you selected in step 1.
This will open the Specify Search Text dialog.
3. Click the "
contains
" link in the "Currently specified strings..." area.
4. Choose "
Matches Regular Expression
" from the drop-down list box, and click
OK
.
5. If you need help creating your regexp or want to test it then click "
Test regular expression
." If you do not need to use the Test Regular Expression dialog then type your regexp into the text box provided, click
Add
, and then go to step 8.
6. Type your regular expression into the "Search expression" text box. To simplify the process we have provided a shortcut menu that can be used to easily insert the desired metacharacters into your regexp. Click the ">" button to access this menu.
When you choose an option from this menu its corresponding metacharacter will be inserted into the expression and the text insertion point will be moved to the appropriate place required by the character.
7. Type any text that you wish to use to test your expression in the text area provided, and click
Test
. When you are finished testing your expression, click
OK
.
8. Click

3. If you chose the "Search...header" action in step 1, then use the drop-down list box provided to choose the header that you wish to search, or type a header into the box if the desired header isn't listed. If you did not choose the
"Search...header" action in step 1 then skip this step.
4. Type the
search
expression that you wish to use in this action. To simplify the process we have provided a shortcut menu that can be used to easily insert the desired metacharacters into your regexp. Click the ">" button to access this menu.
When you choose an option from this menu its corresponding metacharacter will be inserted into the expression and the text insertion point will be moved to the appropriate place required by the character.
5. Type the
replace
expression that you wish to use in this action. As with the
search
expression we have provided a metacharacter shortcut menu for this option as well. Leave this text box blank if you wish to delete a matched sub-string instead of replace it with more text.
6. Click "
Match case
" if you want the expression to be case sensitive.
7. Click Regular expression if you want the search and replace strings to be treated as regular expressions. Otherwise each will be treated as a simple sub-string search and replace—it will look for an exact literal match of the text rather than process it as a regular expression.
8. If you do not need to test your expression then skip this step. If you do need to test your expression then click "
Run Test
." On the Search and Replace Tester dialog, type your search and replace expressions and the text that you wish to test with, then click
Test
. When you are finished testing your regexps click

5.1.1.3.1 Message Macros
For your convenience, certain macros may be used in the notification messages and other messages that the Content Filters generate. You may use any of the following macros:
$ACTUALTO$
Some messages may contain an "ActualTo" field which generally represents the destination mailbox and host as it was entered by the original user prior to any reformatting or alias translation. This macro is replaced with that

Lists the version of AntiVirus that you are using.
This macro is replaced with the current time when the message is being processed.
Some messages may contain an "ActualFrom" field which generally represents the origination mailbox and host prior to any reformatting or alias translation. This macro is replaced with that value.
This macro is replaced by the name of the rule whose criteria the message matched.
Generates a unique ID with 11 alpha-numeric characters. Example: 0XVBASADTZC
This macro will cause the value of the header specified in place of the "xx" to be expanded in the reformatted message. For example: If the original message has "

$HEADER:TO$ macro will expand to "[email protected]".
If the original message has "Subject: This is the subject" then the
$HEADER:SUBJECT$ macro would be replaced with the text "This is the subject"
As with
$HEADER:XX$
above, this macro will expand to the value of the
Message-ID header.
When one or more attachments are removed from the message, this macro will list them.
When one or more viruses is found in a message, this macro will list them.
This macro expands to the f i le name of the current message being processed.

Recipients
This list of recipients corresponds to the various "

" options located on the Notifications tab. These addresses will receive notification messages when one of the Administrator options is selected on that tab. To add an address to this section, type it into the space provided and then click Add. To remove an address, select it from the list and then click Remove.
Only send antivirus update notification on failure
Click this checkbox if you wish to send antivirus update notification messages only when the update attempt fails for some reason.
Do not send any notifications to foreign domains
Check this box if you wish to restrict Content Filter notification messages to local domain recipients. This option is disabled by default.
5.1.1.5 Compression
With the controls on this tab you can cause message attachments to be automatically compressed or decompressed before the message is delivered. The level of compression can be controlled as well as several other parameters and exclusions. This feature could significantly reduce the amount of bandwidth and throughput required to deliver your outbound messages.

Security Menu 449
Outbound Compression
Enable compression of attachments for outbound messages
Click this checkbox if you want to enable automatic message attachment compression for outbound remote mail messages. Enabling this control will not cause all message attachments to be compressed; it simply turns the feature on. Whether an outbound message
' s files are compressed or not is determined by the remaining settings on this tab.
Compress outbound local domain attachments
Enabling this control will cause the file compression settings to be applied to all outbound mail – even those messages whose destination is another local address.
Inbound Compression
Enable decompression of attachments for inbound messages
Click this checkbox if you want to enable automatic decompression of inbound remote mail message attachments. When a message arrives with a zipped attachment, MDaemon will decompress it before delivering it to the local user
' s mailbox.
Decompress inbound local domain attachments
Enable this control if you want automatic decompression to apply to local mail as well.
Compression Options
Create self-extracting zips
Click this checkbox if you want the compression files that MDaemon creates to be self-extracting zip files with an
EXE
file extension. This is useful if you are concerned that the message recipients may not have access to a decompression utility. Selfextracting zip files can be decompressed simply by double-clicking on them.
Compress only if compression % is greater than XX%
MDaemon will not compress a message
' s attachments before sending it unless they can be compressed by a percentage greater than the value specified in this control.
For example, if you designate a value of 20 and a given attachment can
' t be compressed by at least 21% then MDaemon will not compress it before sending the message.
MDaemon must first compress a file to determine by what percentage it can be compressed. Thus, this feature does not prevent files from being compressed – it simply prevents file attachments from being sent in a compressed format when they cannot be compressed beyond the designated value. In other words, if after compressing the file MDaemon finds that it couldn't be compressed by more than this value, the compression will be disregarded and the message will be delivered with its attachments unchanged.

450 MDaemon Messaging Server 17.0
Compress if total attachment size is greater than XX KB
When automatic attachment compression is enabled, MDaemon will only attempt to compress a message
' s attachments when their total size exceeds the value specified here. Messages with total attachment sizes below this threshold will be delivered normally with the attachments unchanged.
Compression level
Use the drop-down list box to choose the degree of compression that you want
MDaemon to apply to automatically compressed attachments. You can choose three levels of compression: minimum (fastest compression process with least compression), medium (default value), or maximum (slowest compression process but highest degree of compression).
Use fixed archive name: [archive name]
Click this checkbox and choose a name if you want the automatically compressed attachments to have a specific filename.
Compression exclusions
Exclude these attachments...
Click this button to specify files that you want to exclude from the automatic compression features. When a message attachment matches one of these filenames it will not be compressed, regardless of the compression settings. Wildcards are permitted in these entries. Therefore, you could specify "*.exe", for example, and all files ending with ".exe" would remain uncompressed.
Exclude these domains...
Click this button to specify recipient domains whose messages you wish to exclude from automatic compression. Messages bound for these domains will not have their file attachments compressed, regardless of your compression settings.

Enable AntiVirus scanning
Click this checkbox to enable AntiVirus scanning of messages. When MDaemon receives a message with attachments, it will scan them for viruses before delivering the message to its final destination.
Exclude gateways from virus scanning
Click this checkbox if you want messages bound for one of MDaemon
' s domain gateways to be excluded from virus scanning. This may be desirable for those who wish to leave the scanning of those messages to the domain
' s own mail server. For more information on domain gateways, see

.
Refuse to accept messages that are infected with viruses
Click this option is you wish to scan incoming messages for viruses during the SMTP session rather than after the session is concluded, and then reject those messages found to contain viruses. Because each incoming message is scanned before
MDaemon officially accepts the message and concludes the session, the sending server is still responsible for it—the message hasn't technically been delivered yet.
Thus the message can be rejected outright when a virus is found. Further, because the message was rejected, no further AntiVirus related actions listed on this dialog

will be taken. No quarantine or cleaning procedures will be taken, and no notification messages will be sent. This can greatly reduce the number of infected messages and virus notification messages that you and your users receive.
The SMTP-(in) log will show the result of AV processing. The possible results you might see are: the message was scanned and found infected with a virus the message was scanned and no virus was found the message could not be scanned (usually because a ZIP or other type or attachment could not be opened/accessed) the message could not be scanned (it exceeds the max size limit) an error occurred during the scan
Configure Exclusions
Click the Configure Exclusions button to specify recipient addresses to exclude from virus scanning. Messages bound for these addresses will not be scanned for viruses.
Wildcards are allowed in these addresses. You could therefore use this feature to exclude entire domains or specific mailboxes across all domains. For example,
"*@example.com or "VirusArchive@*".
When viruses are detected...
Click one of the options in this section to designate the action that MDaemon will take when MDaemon detects a virus.
...do nothing (use content filter to handle)
Choose this option if you wish to take none of the above actions, and have set up content filter rules to take some alternative actions instead.
...delete the entire message
This option will delete the entire message rather than just the attachment when a virus is found. Because this deletes the whole message, the "

" option doesn't apply. However, you can still send a notification message to the recipient by using the controls on the Notifications tab.
...quarantine the entire message to...
This option is like the "

" option above, but the message will be quarantined in the specified location rather than deleted.
...delete the infected attachment
This option will delete the infected attachment. The message will still be delivered to the recipient but without the infected attachment. You can use the
"

" control on the bottom of this dialog to add text to the message informing the user that an infected attachment was deleted.
...quarantine the infected attachment to...
Choose this option and specify a location in the space provided if you want infected attachments to be quarantined to that location rather than deleted or cleaned. Like the "

delivered to the recipient but without the infected attachment.
...clean the infected attachment
When this option is chosen, MDaemon will attempt to clean (i.e. disable) the infected attachment. If the attachment cannot be cleaned, it will be deleted.
Quarantine messages that cannot be scanned
When this option is enabled, MDaemon will quarantine any messages it is unable to scan, such as some containing password-protected files.
Allow password-protected files in exclusion list...
Use this option if you wish to allow a message with a password-protected, nonscannable file to pass through antivirus scanner if the file name or type is in the exclusion list.

5.2 Outbreak Protection
Outbreak Protection (OP) is an optional add-on for MDaemon Private Cloud and is accessible from MDaemon
' s S ecuri ty menu (S ecuri ty » Outbreak protecti on..., or Ctrl
+S hi ft+1
). It is a revolutionary real time anti-spam, anti-virus, and anti-phishing technology capable of proactively protecting an MDaemon email infrastructure automatically and within minutes of an outbreak.
Outbreak Protection is completely content agnostic, meaning that it doesn't rely on
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 457
strict lexical analysis of message content. Thus, it doesn't require heuristic rules, content filtering, or signature updates. Further, that means it is not fooled by the addition of seed text, clever spelling changes, social engineering tactics, language barriers, or differences in encoding techniques. Instead, OP relies on the mathematical analysis of message structure and message distribution characteristics over SMTP—it analyzes "patterns" associated with an email transmission and compares them to similar patterns collected from millions of email messages worldwide, which are sampled and compared in real time.
Because messages are being analyzed worldwide in real time, protection is provided within minutes—often seconds—of a new outbreak. For viruses, this level of protection is critical since it is often hours after an outbreak before a traditional antivirus vendor can verify and submit a virus signature update, and it can then be even longer before that update is put into production use. During that interval, servers without Outbreak
Protection are vulnerable to that particular outbreak. Similarly, for spam messages it will often take time and effort to analyze the spam and create a safe filtering rule before it will be recognized by traditional heuristic and content based systems.
It is important to note, however, that the Outbreak Protection feature is not a replacement for traditional anti-virus, anti-spam, and anti-phishing techniques. In fact,
OP provides another specialized layer of protection on top of the existing heuristics, signature, and content based tools found within MDaemon. Specifically, OP is designed to deal with large-scale outbreaks rather than old, unique, or specifically targeted messages that can be more readily caught by the traditional tools.
Outbreak Protection is based on CommTouch RPD and Zero-
Hour technology. It works by extracting patterns from your incoming mail and comparing them to patterns taken from millions of internet email messages sampled daily from numerous sources all over the world. In no way is the actual content of any message ever transmitted, nor can the message content ever be derived from the extracted patterns.

The remaining options on this dialog are used to determine what will be done with messages found to be part of an outbreak, and to designate the senders that will be exempt from OP processing.
Viruses should be...

Select this option if you wish to accept messages that OP determines are part of a virus outbreak. Although these messages will not be rejected by the server,
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 459
they will be quarantined instead of delivered to their intended recipients.
Quarantined messages are placed in the quarantine folder.
Spam should be...
blocked in real time
Select this option if you wish to block messages during the SMTP process when
OP confirms that they are part of a spam outbreak. These messages will not be flagged as spam and delivered to their intended recipients—they will be rejected by the server. Messages classified by OP as "bulk" mail will not be blocked by this option unless you activate the When blocking spam, block messages which
classify as "bulk" spam also option below. Messages classified as "bulk" by OP could simply be a part of certain very large mailing lists or other similar widely distributed content, so you may or may not consider those types of messages to be spam. For that reason, those types of messages generally shouldn't be scored negatively or blocked by OP.
accepted for filtering
Select this option if you wish to accept messages that OP confirms to be part of a spam outbreak, so that they can then be subjected to spam filtering and content filter processing. These messages will not be blocked by OP, but they will have their Spam Filter scores adjusted according to the Score option below.
When using the accepted for filtering option, OP will not directly cause a confirmed spam message to be blocked, but a message may still be blocked by MDaemon during the SMTP process if you have configured the Spam Filter to use the
SMTP rejects messages with scores greater than or equal to
[xx] option, located on the
474
screen.
For example, if the scoring option below caused a message’s
Spam Filter score to be 15.0, then the message would still be rejected as spam if you had also configured the Spam Filter’s
“SMTP rejects...” option to reject messages that have a score of 15.0 or greater.
Score
When using the accepted for filtering option above, this amount will be added to a message’s Spam Filter score when OP confirms that the message is part of a spam outbreak.
IWF Content
The following option applies to content identified by the Internet Watch Foundation
(IWF) as referring to child abuse image sites (i.e. child pornography sites). It enables OP to use an integrated URL list provided by the IWF to detect and tag messages that refer to that content. The IWF operates an independent internet
“hotline” for reporting potentially illegal online content, including child abuse content hosted anywhere in the world. They work in partnership with the police, governments, the wider online industry and the public to combat the availability of illegal online content. The Foundation’s URL list is updated daily with new sites
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

hosting child abuse images.
Many organizations have internal compliance rules governing the content of email sent or received by its employees, especially with regard to obscene or illegal material. In addition, many countries have outlawed the sending or receipt of such content. This feature can assist in your efforts to ensure compliance.
For more on the IWF, see: http://www.iwf.org.uk/
IWF content should be...
blocked in real time
Choose this option if you wish to reject incoming messages during the SMTP process when they have IWF restricted content.
accepted for filtering
Choose this option if you wish to increase a message’s Spam Filter score instead of rejecting it when it has IWF restricted content. The Spam Filter score will be increased by the amount specified in the Score option below.
Score
When the accepted for filtering option above is selected, this is the amount that will be added to a message’s Spam Filter score when it contains IWF restricted content.
When blocking spam, block messages which classify as “bulk” spam also
Sometimes OP will identify certain messages that could be considered spam but aren't being sent from a known spammer or bot-net—as is sometimes the case with legitimate bulk mailings and newsletters. OP classifies these types of messages as
"Spam (bulk)" rather than "Spam (confirmed)." Click this checkbox if you wish to apply OP’s spam blocking features to "Spam (bulk)" mail as well. If this option is disabled, only messages classified as "Spam (confirmed)" will be affected by OP’s spam blocking features above. Accepting this type of spam for later processing may be necessary for sites that want to receive bulk mailings but for some reason cannot white list the source or recipient.
Log processing activity to MDaemon
' s plugin log file
Enable this checkbox if you wish to log all OP processing activity into MDaemon
' s plugin log file.
Exceptions
Authenticated SMTP sessions are exempt from OP processing
When this option is enabled, authenticated SMTP sessions are exempt from OP processing. This means that messages sent during that session will not be subjected to Outbreak Protection checks.
SMTP sessions from trusted IPs are exempt from OP processing
Enable this option if you wish to exempt trusted IP addresses from Outbreak
Protection—messages arriving from a server at a trusted IP address not be

subjected to OP checks.
SPF/DKIM approved mail is exempt from OP processing
Click this checkbox if you wish to exempt a message from OP processing when the sending domain appears on the
546
and it is validated by SPF or DKIM.
Spam Trap and Spam Filter white listed addresses are exempt from OP processing
Click this option if you wish to exempt the
504
and Spam Filter white lists from Outbreak Protection. The "White List" applies to the recipient, or RCPT value given during the SMTP session. The "White List (from)" applies to the sender, or MAIL value given during the SMTP session. These operations are not based on message header values.
False Positives and False Negatives
False positives, or classifying a legitimate message improperly as part of an outbreak, should rarely if ever happen. Should a false positive occur, however, you can send that message to us at
for spam/phishing false positives or
for virus false positives, so that we can use it to help refine and improve our detection and classification processes.
False negatives, or classifying a message as not part of an outbreak even though it is still spam or an attack, will happen more often than false positives. However, it worth noting that OP is not designed to catch all spam, virus attacks, and the like— it is simply one layer of protection that specifically targets outbreaks. Old messages, specifically targeted messages and the like, which are not part of a currently ongoing outbreak, might pass the OP check. Those sorts of messages should then be caught by the other AntiVirus and MDaemon features further down the processing chain. Should a false negative occur, however, you can send that message to us at
for spam/phishing false negatives or
for virus false negatives, so that we can use it to help refine and improve our detection and classification processes.
When sending improperly classified messages to us, the original email should be sent as a MIME email attachment rather than forwarded. Otherwise, headers and other information critical to the classification process will be lost.

5.4 MDPGP
Security Menu 465
OpenPGP is an industry standard protocol for exchanging encrypted data, and there are a variety of OpenPGP plugins for email clients that make it possible for users to send and receive encrypted messages. MDPGP is MDaemon's integrated OpenPGP component that can provide encryption, decryption, and basic key management services for your users without requiring them to use an email client plugin.
MDPGP encrypts and decrypts emails using a public-key/private-key system. To do this, when you wish to use MDPGP to send a private and secure message to someone,
MDPGP will encrypt that message using a "key" that you previously obtained from that person (i.e. his "public key") and imported into MDPGP. Conversely, if he wishes to send a private message to you, then he must encrypt the message using your public key, which he obtained from you. Giving the sender your public key is absolutely necessary, because without it he can't send you an OpenPGP encrypted message. Your unique public key must be used to encrypt the message because your unique private key is what MDPGP will use to decrypt the message when it arrives.
In order for MDPGP to manage signing, encrypting, and decrypting messages, it maintains two stores of keys (i.e. keyrings)—one for public keys and one for private keys. MDPGP can generate your users' keys automatically as needed, or you can create them manually for specific users. You can also import keys that were created elsewhere. Further, MDaemon can look for public keys attached to authenticated
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
466 MDaemon Messaging Server 17.0
messages from local users, and then import those keys automatically. That way a user can request a public key from someone and then email that key to himself so that
MDPGP will detect it and then import it into the public keyring. MDPGP will never store multiple copies of the same key, but there can be multiple different keys for a single address. Finally, whenever a message arrives for an address that has a key in a keyring, MDPGP will sign, encrypt, or decrypt the message as needed, according to your settings. If an address has multiple keys, MDPGP will use the one you have designated as the preferred key to encrypt the message. If no preferred key has been designated then MDPGP will use the first one. When decrypting a message MDaemon will try each one.
You can configure MDPGP's signing and encryption services to operate either automatically or manually. When set to operate automatically, MDPGP will automatically sign and encrypt messages whenever possible. When set to operate manually, MDPGP will only sign or encrypt a message when the sending user inserts a special command into the message's Subject. In any case messages will only be signed or encrypted (or decrypted) when the account has been given permission to use those services.
The OpenPGP specification is outlined in RFCs 4880 and 3156 .
Enabling MDPGP
Enable MDPGP
MDPGP is enabled by default, but it will still not sign, encrypt, or decrypt any messages until you create or import keys into its keyrings, or until you use the option below to set MDPGP to Create keys automatically.
Enable encryption & signing services
By default messages can be signed and encrypted when the required keys are in the keyring. Disable this option if you do not wish to allow MDPGP to sign or encrypt messages.
Messages can be signed without being encrypted, but any message that is encrypted by MDPGP will always be signed as well.
Enable decryption & verification services
By default incoming encrypted messages will be decrypted if the recipient's private key is known. Further, MDPGP will also verify embedded signatures in unencrypted messages. Note, however, that both the recipient and sender must be authorized to use the decryption and verification services, either through the
"Authorize all..." options or "Configure exactly who..." option below (everyone is authorized by default). Disable this option if you do not wish to verify embedded signatures or allow MDPGP to decrypt any messages, for example if you want all of your users to handle their own decryption via an email client plugin. When disabled, any incoming encrypted message will be handled like a normal message and placed in the recipient's mailbox.

Security Menu 467
Collect public-keys from DNS (pka1) and cache for [xx] hours
Enable this option if you want MDPGP to query for message recipient public-keys over DNS using PKA1. This is useful because it automates the process of obtaining some recipients' public keys, preventing you or your users from having to obtain and import them manually in order to send encrypted messages. When PKA1 queries are made, any key URI found is immediately collected, validated, and added to the keyring. Keys successfully collected and imported to the key-ring using this method are tracked in a file called fetchedkeys.txt, and these keys will automatically expire after the number of hours specified in this option or according to the TTL value of the PKA1 record that referred them, whichever value is greater. Therefore the value specified here is the minimum length of time that a key will be cached. The default value is 12 hours and the lowest value allowed is 1 hour.
If you wish to publish your own public-keys to DNS then you must create special TXT records. For example, for the user [email protected]
with the key-id: 0A2B3C4D5E6F7G8H, in the DNS for domain "example.com" you would create a TXT record at "frank._pka.example.com" (replacing the @ in the email address with the string "._pka."). The data for the TXT record would look something like this: "v=pka1; fpr=<key's full fingerprint>; uri=<WorldClient-URL>/
WorldClient.dll?view=mdpgp&k=0A2B3C4D5E6F7G8H
" where
<key's full fingerprint>
is the full fingerprint of the key
(40 characters long representing the full 20 byte fingerprint value). You can see a key's full fingerprint value by double clicking on the key in the MDPGP GUI.
Send public-keys over HTTP (WorldClient)
Enable this option if you wish to use WorldClient as a basic public-key server;
WorldClient will honor requests for your users' public-keys. The format of the URL to make the request looks like this: "http://<WorldClient-URL>/WorldClient.dll?
View=MDPGP&k=<Key-ID>
". Where <WorldClient-URL> is the path to your
WorldClient server (for example, "http://wc.example.com") and <Key-ID> is the sixteen character key-id of the key you want (for example, "0A1B3C4D5E6F7G8H").
The key-id is constructed from the last 8 bytes of the key fingerprint - 16 characters in total.
Authorize all local MDaemon users for all services
By default all local MDaemon user accounts are authorized to use any of the MDPGP services that you have enabled: signing, encryption, decryption, and verification. If there are specific users whom you do not wish to allow to use one or more of those services, you can use the "Configure exactly who can and can not use MDPGP
services" option below to exclude them. Disable this option if you only wish to authorize specific local users. In that case use the "Configure exactly who can and
can not use MDPGP services" option below to grant access to whomever you choose.
Authorize all non-local (foreign) users for decrypt/verify services
By default any incoming encrypted message for a local recipient from a non-local
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
468 MDaemon Messaging Server 17.0
sender can be decrypted if MDPGP knows the local recipient's private key. Similarly,
MDPGP will verify embedded signatures in incoming messages from non-local users. If there are certain non-local senders whose messages you do not wish to decrypt or verify, then you can use the "Configure exactly who can and can not use MDPGP
services" option below to restrict those senders from those services. Disable this option if you do not wish to decrypt messages or verify embedded signatures when the sender is a non-local address. In that case you can still use the "Configure
exactly who can and can not use MDPGP services" option below to specify exceptions to that restriction.
Configure exactly who can and can not use MDPGP services
Click this button to open the rules.txt file for configuring user permissions for
MDPGP. Using this file you can specify who is allowed to sign messages, encrypt messages, and have messages decrypted. You can also specifically restrict users from these options. For example, you could use the rule "+*@example.com" to allow all example.com users to encrypt messages, but then add "[email protected]" to specifically prevent [email protected] from being able to do so. See the text at the top of the rules.txt file for examples and instructions.
Rules.txt Notes and Syntax
Only SMTP authenticated email from users of this MDaemon server are eligible for encryption service. You can, however, specify non-local addresses that you wish restrict from the encryption service, meaning that MDPGP will not encrypt messages to them, even if the public key is known.
If there is a conflict between the settings in rules.txt and the global
"Authorize all local MDaemon users for all services" option, the rules.txt
setting is used.
If there is a conflict between the settings in rules.txt and the global
"Authorize all non-local (foreign) users for decrypt/verify services" option, the rules.txt setting is used.
Text after # on a line is ignored.
Separate multiple email addresses on the same line with a space.
Wildcards (* and ?) in email addresses are permitted.
Even though MDPGP encrypted messages are always signed, granting encryption permission to a user doesn't also grant that user permission to sign unencrypted messages. In order to sign an unencrypted message the account must be given signing permission.
Each email address must be prefixed with one of the following tags:
+ (plus) - address can use MDPGP encryption service.
- (minus) - address cannot use MDPGP encryption service.
! (exclamation) - address can use MDPGP decryption service.
~ (tilde) - address cannot use MDPGP decryption service.
^ (caret) - address can use MDPGP signing service.
= (equal) - address cannot use MDPGP signing service.

Encryption/Signing Modes
Automatic Mode
Use the Settings options to configure MDPGP to sign and encrypt messages automatically for accounts permitted to do so. When an account sends an authenticated message and MDPGP knows the required key, the message will be signed or encrypted according to the settings below.
The special Subject codes outlined in the Manual Mode section below always take precedence over the Automatic Mode options. Therefore if one of these options is disabled, an account that is permitted to sign or encrypt messages can still manually cause a message to be signed or encrypted by using one of the codes.
Settings
Encrypt mail automatically if recipient's public key is known
By default, if an account is allowed to encrypt messages, MDPGP will encrypt them automatically if the recipient's public key is known. Disable this option if you do not wish to encrypt them automatically; messages can still be encrypted manually by using the special codes outlined in the Manual Mode section below.
Sign mail automatically if sender's private key is known
Click this option if you want MDPGP to sign messages automatically when the sending account's private key is known, if the account is allowed to sign messages.
Even when this option is disabled, messages can still be signed manually by using the special codes outlined in the Manual Mode section below.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
470 MDaemon Messaging Server 17.0
Encrypt/Sign mail between users of the same domain
When MDPGP is set to encrypt or sign messages automatically, this option causes MDPGP to do this even when messages are sent between users of the same domain, provided the required keys are known. This option is enabled by default.
Encrypt/Sign mail between users of local MDaemon domains
When MDPGP is set to encrypt or sign messages automatically, this option causes MDPGP to do this even when messages are being sent between users of local MDaemon domains, provided the required keys are known. For example, if your MDaemon domains include "example.com" and "example.net," then messages sent between those domains' users will be automatically encrypted or signed.
This option is enabled by default.
Encrypt/Sign mail sent to self
When MDPGP is set to encrypt or sign messages automatically, this will be done even when the MDaemon user is sending a message to himself (e.g.
[email protected] sending to [email protected]). Therefore if the account has permission to use both encryption and decryption (the default settings) then
MDPGP will accept the user's message, encrypt it, and then immediately decrypt it and place it in the same user's mailbox. If, however, the account isn't configured for decryption, this will cause the message to be encrypted and then placed in the same user's mailbox still encrypted. This option is enabled by default.
Manual Mode
When you have disabled the Sign mail automatically... and Encrypt mail
automatically... options outlined above, you are using MDPGP in Manual Mode. MDPGP will not sign or encrypt any messages except those that are authenticated and have one of the following codes in the message's Subject header:
--pgps
--pgpe
--pgpx
Sign this message if possible. Code can be placed at the beginning or end of the Subject.
Encrypt this message if possible. Code can be placed at the beginning or end of the Subject.
The message MUST be encrypted. If it cannot be encrypted
(e.g. because the recipient's key isn't known) then do not deliver it; the message will be bounced/returned to the sender.
Code can be placed at the beginning or end of the Subject.
--pgpk
Send me my public key. The user places this code at the beginning of the Subject and sends the message to himself.
MDPGP will then email the user his public key.
-pgpk<Email>
Send me this address' public key. The user places this code at the beginning of the Subject and sends the message to himself.
MDPGP will then email the user the address' public key.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Example:
Subject: --pgpk<[email protected]>
Security Menu 471
Key Management
Public and private keys are managed using the options on the bottom half of the
MDPGP dialog. There is an entry for each key, and you can right-click any entry to export the key, delete it, or enable/disable it. When you click Export Key it will be saved to the \MDaemon\Pem\_mdpgp\exports\ folder and you can optionally email the public key to an email address. "Show Local/Remote" and "Filter" options are provided to help you locate certain addresses or groups.
Email public-keys when requests are made (--pgpk command)
When this option is enabled, non-local users can request public-keys via email. An email can be sent to your MDaemon server's system account (e.g.
[email protected]) with "--pgpk<email address>" as the subject (e.g. -pgpk<[email protected]>
). If a public-key for <email address> exists it will be emailed back to the requester. This option is disabled by default.
Email details of encryption failures to sender (--pgpe command)
When someone uses the --pgpe command to send encrypted mail and that encryption fails (for example, because no encryption key is found), then this option will cause a notification email to be sent back to the sender informing him or her of the failure. This option is disabled by default, meaning no failure notification message will be sent.
Auto-import public-keys sent from authenticated users
By default, when an authenticated user sends an email message with a public key in
ASCII armored format attached, MDPGP will import that public key into the keyring.
This is a simple way for a user to get a contact's public key into MDPGP, by emailing the public key to himself as an attachment. Disable this option if you do not wish to auto-import public keys.
Create keys automatically
Enable this option if you want MDPGP to create a public/private key pair automatically for each MDaemon user. Rather than generate them all at once, however, MDPGP will create them over time, creating each user's key pair the next time a message is processed for that user. This option is disabled by default to conserve resources and avoid needlessly generating keys for accounts that may never use MDPGP.
Key size
Use this option to specify the key size for keys that MDPGP generates. You can set the key size to 1024, 2048, or 4096. The default setting is 2048 bit keys.
Expires in [xx] days (0=never)
Use this option to specify the number of days from creation date that a key generated by MDPGP will be valid before it expires. Set the option to "0" if you do not want keys to expire. The default setting is 0.

Create keys for a specific user
To manually generate a key pair for an account:
1. Click Create keys for a specific user.
2. Select the account from the drop-down list.
3. Optional: Check the box Email public key to key owner... if you wish to send the key to the user as an email attachment.
4. Click Ok.
Import keys
If you wish to import a key file into MDPGP manually, click this button, locate the key file, and click Open. When importing a private key file, you do not need to import the corresponding public key, as it is included in the private key. If you are importing a private key protected by a passphrase then MDPGP will prompt you to enter the passphrase. Without the passphrase you cannot import the private key.
After importing a private key, MDaemon will change that key's passphrase to whichever passphrase MDPGP is currently using.
Change passphrase
Private keys are protected at all times by a passphrase. When attempting to import a private key, you must enter its passphrase. When exporting a private key, that exported key will still be protected by the passphrase, and it cannot be used or imported elsewhere without it. MDPGP's default passphrase is MDaemon. For security reasons you should change this passphrase after you begin using MDPGP, because until you do so, every key created by or successfully imported into MDPGP will have its passphrase set (or changed) to MDaemon. You can change the

Security Menu 473
passphrase at any time by clicking Change passphrase on the MDPGP screen.
When you change the passphrase, every private key on the keyring is updated to the new passphrase.
Backup data files
Click this button to make a backup of your current Keyring.private and
Keyring.public
keyring files. By default the backup files will be copied to:
"\MDaemon\Pem\_mdpgp\backups" and have a date and .bak extension appended to the filenames.
Forwarded messages are not encrypted.
Autoresponder messages are not encrypted.
Key servers and key revocation are not supported, except as outlined in the "Collect public-keys from DNS (pka1) and
cache for [xx] hours" and "Send public-keys over HTTP
(WorldClient)" options above.
The Content Filter encrypt action does not act on messages already encrypted, and the encrypt and decrypt actions are subject to all MDPGP configuration requirements.
The drop-down lists that display MDaemon accounts show the first 500 accounts by default. You can set

5.5 Spam Filter
5.5.1 Spam Filter
The Spam Filter is one of the main features in MDaemon
' s extensive suite of spam prevention tools. It incorporates heuristics to examine incoming email messages in order to compute a "score" based on a complex system of rules. The score is then used to determine the likelihood of a message being spam, and certain actions can be taken based on that score — you can refuse the message, flag it as possible spam, and so on.
Addresses can be white or black listed, or designated as completely exempt from Spam
Filter examination. You can have a spam report inserted into messages, showing their spam scores and how those scores were achieved, or you can generate the report as a separate email and have the original spam message included with it as an attachment.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
474 MDaemon Messaging Server 17.0
Further, you can even use
478
learning to help the Spam Filter learn to identify spam more accurately over time, thus increasing its reliability.
Finally, by examining many thousands of known spam messages, the rules have been optimized over time and are very reliable in detecting the fingerprint of a spam message. You can, however, customize or add new rules by editing the Spam Filter
' s configuration files to meet your specific needs.
MDaemon
' s Spam Filter uses an integrated, popular open-source heuristic technology.
The homepage for the open-source project is: http://www.spamassassin.org

A message is spam if its score is greater or equal to [XX] (0.0-500.0)
The value that you specify here is the required spam threshold that MDaemon will compare to each message
' s spam score. Any message with a spam score greater than or equal to this amount will be considered spam, and then the appropriate actions will be taken based on your other Spam Filter settings.
SMTP rejects messages with scores greater or equal to XX (0=never)
Use this option to designate a spam score rejection threshold. When a message
' s spam score is greater than or equal to this score it will be rejected completely rather than proceed through the rest of the options and possibly be delivered. The value of this option should always be greater than the value of the "
A message is spam if its score...
" option above. Otherwise, a message would never be considered spam and have the rest of the Spam Filter
' s options applied to it—it would simply be rejected during delivery. Use "0" in this option if wish to disable scanning during the SMTP process, and if you do not want MDaemon to reject any messages regardless of their scores. If SMTP scanning is disabled then a queue-based scan will still be performed on the messages after they are accepted. The default setting for this option is "12.0".
Example,
If you have the spam score threshold set to 5.0 and the rejection threshold set to
10.0, then any message with a spam score that is greater than or equal to 5.0 but less than 10.0 will be considered spam and handled according to the rest of your
Spam Filter settings. Any message with a spam score greater than or equal to 10.0
will be rejected by MDaemon during the delivery process.
You should monitor the spam filter's performance over time and refine both the spam and rejection thresholds to suit your need. For most people, however, a spam score threshold of 5.0
will catch most spam, with relatively few false negatives (spam that slips through unrecognized) and rarely any false positives
(messages flagged as spam that are not). A rejection threshold of 10-15 will cause only messages that are almost certainly spam to be rejected. It is extremely rare that a legitimate message will have a score that high. The default rejection threshold is 12.

Skip queue-based scan on messages processed during SMTP sessions
By default, MDaemon scans messages during the SMTP session to determine whether or not they should be rejected for having a spam score above the rejection threshold. For messages that are accepted MDaemon will then perform another, queue-based, scan and treat the messages accordingly, based on their scores and your spam filter configuration. Click this option if you want MDaemon to omit the queue-based scan and treat the results of the initial Spam Filter scan as definitive.
This can potentially significantly decrease CPU usage and increase the efficiency of the AntiSpam system. However, only the default SpamAssassin headers will be added to messages when the queue-based scan is omitted. If you have made any changes to the default SpamAssassin headers or specified custom headers in your
local.cf
file, those changes and additions will be ignored.
Refuse to accept message if an error occurs during SMTP scanning
Click this option if you want a message to be refused when an error is encountered while it is being scanned during the SMTP process.
Subject tag
This tag will be inserted at the beginning of the Subject header of all messages that meet or exceed the required spam score threshold. It can contain information about the spam score, and you can use your IMAP message filters to search for it and filter the message accordingly (assuming that you have the Spam Filter configured to continue delivering spam messages). This is a simple method for automatically routing spam messages to a designated "spam" folder. If you want to dynamically insert the message
' s spam score and the value of the required spam threshold then use the tag "
_HITS_
" for the message
' s score and "
_REQD_
" for the required threshold. Alternatively, you can use "
_SCORE(0)_
" instead of "
_HITS_
"— this will insert a leading zero into lower scores, which can help ensure the proper sort-order when sorting messages by subject in some email clients.
Example,
A subject tag set to:
***SPAM*** Score/Req: _HITS_/_REQD_ will cause a spam message with a score of 6.2 and the subject: "Hey, here
' s some spam!" to be changed to "***SPAM*** Score/Req: 6.2/5.0 – Hey, here
' s some spam!"
If "
_SCORE(0)_
" is substituted for "
_HITS_
" then it would be changed to
"***SPAM*** Score/Req: 06.2/5.0 – Hey, here
' s some spam!"
If you do not wish to alter the subject header then leave this option blank. No subject tag will be inserted.
This option is unavailable when you have configured MDaemon to use another server's MDaemon Spam Daemon (MDSpamD) for Spam Filter processing. The Subject tag configuration will be determined by the other server's settings. See:

5.5.1.2 Bayesian Classification
Bayesian Classification is unavailable when you have configured
MDaemon to use another server's MDaemon Spam Daemon
(MDSpamD) for Spam Filter processing. All Bayesian learning will be performed on the other server. See the
484
screen for more information.
The Spam Filter supports Bayesian learning, which is a statistical process that can optionally be used to analyze spam and non-spam messages in order to increase the reliability of spam recognition over time. You can designate a folder for spam messages and non-spam message that will can be scanned manually or automatically at regular intervals. All of the messages in those folders will be analyzed and indexed so that new messages can be compared to them statistically in order to determine the likelihood that they are spam. The Spam Filter can then increase or decrease a message
' s spam score based upon the results of its Bayesian comparison.
The Spam Filter will not apply a Bayesian classification to messages until a Bayesian analysis has been performed on the
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 479
number of spam and non-spam messages designated on the
482
screen. This is necessary in order for the Spam Filter to have a sufficient pool of statistics to draw from when making the Bayesian comparison. Once you have given the system these messages to analyze, it will be sufficiently equipped to begin applying the results of a
Bayesian comparison to each incoming message's spam score.
By continuing to analyze even more messages the Bayesian classifications will become more accurate over time.
Bayesian Classification
Enable Bayesian classification
Click this check box if you want each message
' s spam score to be adjusted based on a comparison to the currently known Bayesian statistics.
Schedule Bayesian learning for midnight each night
When this option is active, once each day at midnight the Spam Filter will analyze and then delete all messages contained in the spam and non-spam folders specified below. If you wish to schedule Bayesian learning for some other time interval then clear this option and use the
Schedule Bayesian learning for once every XX hours
option below. If you do not wish Bayesian learning to ever occur automatically, then clear this option and specify "0" hours in the option below.
Schedule Bayesian learning for once every XX hours (0=never)
If you wish Bayesian learning to occur at some time interval other than once each night at midnight, then clear the above option and specify a number of hours in this option instead. Each time that number of hours has elapsed, the Spam Filter will analyze and then delete all messages contained in the spam and non-spam folders specified below. If you do not wish Bayesian learning to ever occur automatically, then clear the above option and specify "0" hours in this option.
If for some reason you do not want the messages to be deleted after they are analyzed then you can prevent that by copying
LEARN.BAT
to
MYLEARN.BAT
in the
\MDaemon\App
\
subfolder and then deleting the two lines that begin with "

Click this button to initiate a manual Bayesian analysis of the designated folders rather than waiting for the automatic analysis.
Enable spam and ham forwarding addresses
Click this check box if you wish to allow users to forward spam and non-spam (ham) messages to designated addresses so that the Bayesian system can learn from them. The default addresses that MDaemon will use are "
SpamLearn@<domain>
" and "
HamLearn@<domain>
". Messages sent to these addresses must be received via SMTP from a session that is authenticated using SMTP AUTH. Further, MDaemon expects the messages to be forwarded to the above addresses as attachments of type "
message/rfc822
". Any message of another type that is sent to these email addresses will not be processed.
You can change the addresses MDaemon uses by adding the following key to the
CFilter.INI
file:

SpamLearnAddress=MySpamLearnAddress@
HamLearnAddress=MyNonSpamLearnAddress@
Note: the last character of these values must be "@".

\Bayesian Learning.IMAP\
Root IMAP folder
\Bayesian Learning.IMAP
\Spam.IMAP\
\Bayesian Learning.IMAP\Non-
Spam.IMAP\
This folder is for false negatives
(spam that doesn't score high enough to get flagged as such).
This folder is for false positives
(non-spam messages that erroneously score high enough to get flagged as spam).
By default, access permission to these folders is only granted to local users of local domains and is limited to Lookup and Insert. The postmaster
' s default permissions are Lookup, Read, Insert, and Delete.
Path to known spam folder (false negatives):
This is the path to the folder that will be used for Bayesian analysis of known spam messages. Only copy messages to this folder which you consider to be spam. You should not automate the process of copying messages to this folder unless doing so via the
482
or
504
options. Automating this process by some other means could potentially cause non-spam messages to be

analyzed as spam, which would decrease the reliability of the Bayesian statistics.
Path to known non-spam folder (false positives):
This is the path to the folder that will be used for Bayesian analysis of messages that are definitely
not
spam. Only messages that you do
not
consider to be spam should be copied to this folder. You should not automate the process of copying messages to this folder unless doing so via the
482
options.
Automating this process by some other means could potentially cause spam messages to be analyzed as non-spam, which would decrease the reliability of the
Bayesian statistics.
Pub Folder
Click one of these buttons to designate one of your existing Public Folders as the
Bayesian directory. This is an easy way for your users to place their messages incorrectly categorized as spam or non-spam into your Bayesian directories for analysis. Note, however, that giving access to more people increases the likelihood that some messages will be put into the wrong folders thus skewing the statistics and decreasing reliability.
If you rename a Public folder via a mail client, Windows
Explorer, or some other means, then you must manually reset this path to the appropriate new folder name. If you rename a folder but do not change its path here, the Spam Filter will continue to use this path for the Bayesian folder instead of the new one.

5.5.1.3 Bayesian Auto-learning
Bayesian Auto-learning is unavailable when you have configured MDaemon to use another server's MDaemon Spam
Daemon (MDSpamD) for Spam Filter processing. All Bayesian learning will be performed on the other server. See the
484
screen for more information.
Automatic Learning
Enable Bayesian automatic learning
With automatic Bayesian learning you can designate spam and non-spam scoring thresholds, which make it possible for the Bayesian learning system to learn from messages automatically rather than requiring you to manually place those messages in the spam and non-spam folders. Any message scoring below the non-spam threshold will be treated by automatic learning as non-spam, and any message scoring above the spam threshold will be treated as spam. With automatic learning, old expired tokens that are removed from the database (see
Database Management
below) can be replaced automatically. This prevents the need for manual retraining to recover expired tokens. Automatic Learning can be useful and beneficial as long if you are careful in setting your thresholds, to avoid placing improperly classified
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

messages in the folders.
Non-spam score threshold
Messages with a spam score below this value will be treated as non-spam messages by the Bayesian Classification system.
Spam score threshold
Messages with a spam score above this value will be treated as spam messages by the Bayesian Classification system.
Non-spam samples needed before Bayesian scoring is possible
The Spam Filter will not apply a Bayesian classification to messages until this number of non-spam messages (and spam messages specified in the next option) has been analyzed by the Bayesian system. This is necessary in order for the Spam Filter to have a sufficient pool of statistics to draw from when making the Bayesian comparison. Once you have given the system these messages to analyze, it will be sufficiently equipped to begin applying the results of a Bayesian comparison to each incoming message
' s spam score. By continuing to analyze even more messages the
Bayesian classifications will become more accurate over time.
Spam samples needed before Bayesian scoring is possible
Just as the previous option applies to non-spam messages, this option is for designating the number of
spam
messages that must be analyzed before the Spam
Filter will begin applying a Bayesian classification to messages.
Database Management
Enable Bayesian automatic token expiration
Click this option if you want the Bayesian system to automatically expire database tokens whenever the number of tokens specified below is reached. Setting a token limit can prevent your Bayesian database from getting excessively large.
Maximum Bayesian database tokens
This is the maximum number of Bayesian database tokens allowed. When this number of tokens is reached, the Bayesian system removes the oldest, reducing the number to 75% of this value, or to 100,000 tokens, whichever is higher. The number of tokens will never fall below the larger of those two values regardless of how many tokens are expired. Note: 150,000 database tokens is approximately 8Mb.

5.5.1.4 Spam Daemon (MDSpamD)
MDaemon's spam filtering system runs as a separate daemon—the MDaemon Spam
Daemon (MDSpamD), which is fed messages via TCP/IP for scanning. This greatly increases the Spam Filter
' s performance and makes it possible for you to run MDSpamD locally, on a separate computer, or have MDaemon use another MDSpamD (or any other
Spam Daemon enabled product) running at some other location. By default MDSpamD runs locally and receives messages on port 783 at 127.0.0.1, but you can configure a different port and IP address if wish to send the messages to some other spam daemon running at a different location or on a different port.
MDSpamD Configuration
Host or IP
This is the host or IP address to which MDaemon will send messages to be scanned by MDSpamD. Use
127.0.0.1
if MDSpamD is running locally.
Port
This is the port on which the messages will be sent. The default MDSpamD port is
783.
Ping remote MDSpamD once every XX seconds (0=never)
If you are using a spam daemon that is running at a remote location, you can use this option to ping its location periodically. Use "0" if you do not wish to ping that location.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 485
These options are available when running MDSpamD locally
Show MDSpamD external process window
When MDSpamD is running locally, enable this option if you would like it to run in an external process window. This option will cause the output from MDSpamD to be piped to the external process window rather than to MDaemon
' s internal UI or logging system. Using this option could increase performance since MDSpamD
' s data will not have to be piped into and logged by MDaemon. However, no log file will be created and as such this feature cannot be used with the logging option below, nor will MDSpamD data appear in the
Security»MDSpamD
tab of MDaemon
' s main GUI.
Log all local MDSpamD activity (debug logging—performance drain)
Click this option if you wish to log all MDSpamD activity. This option is unavailable if you are using the
Show MDSpamD external process window
option above. Further, if using user credentials on the
424
dialog rather than running
MDaemon under the SYSTEM account, no MDSpamD activity will be logged.
When using this logging option, you may see decreased performance in your mail system, depending on your system and the level of activity. Generally you should only use this option for debugging purposes.
Maximum message processing threads (1-6)
This is the maximum number of threads that MDaemon will use for internal processing. You can set this value from 1 to 6.
Maximum TCP connections per thread (10-200)
This is the maximum number of TCP connections accepted by an MDSpamD thread before it branches into another thread. You can set this value from 10 to 200.
Listen on and accept connections only from 127.0.0.1
Click this option if do not you wish to allow your local MDSpamD to accept connections from any external source. Only connections from the same machine on which it is running will be allowed.
Listen for connections on this IP
If the previous option is disabled, you can use this option to bind or restrict connections to a specific IP address. Only connections to the designated IP address will be allowed. Use "
<all>
" if you do not wish to restrict MDSpamD to any particular IP address.
Allow connections from these IPs
These are the IP addresses from which MDSpamD will accept incoming connections.
Connections from other IP addresses will be rejected. This is useful if you wish to allow connections from another server in order to share Spam Filter processing.
Optional command line options to pass to MDSpamD:
MDSpamD can accept many command line options, documented at:

If you wish to use any of those options, construct a string containing the desired options and place it here.
Some of those options can be configured via the settings on this dialog and therefore do not need to be set up manually using command line options.
5.5.1.5 White List (automatic)
Automatic White Listing
Use personal contacts, white list and black list files
Click this option to allow each user's personal contacts, white list and black list files to be used as Spam Filter white and black lists. For each incoming message,
MDaemon will search the recipient account
' s contacts, white list, and black list for the sender of the message. If the sender is found then the message will be white or black listed automatically. If you do not wish to apply automatic white and black listing to every MDaemon user then you can disable it for individual users by clearing the
Spam Filter uses personal contacts, white list, and black list files
option on the
657
screen of the Account Editor.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 487
...only whitelist addresses that authenticate using DKIM
When this option is enabled, MDaemon will not white list the message unless the sender was authenticated via
519
(DKIM). This option helps to avoid white listing messages with spoofed addresses.
Automatically update white listed contacts
When this option is enabled, MDaemon will automatically add any non-local email addresses to which you send mail to your personal white list folder. When used in conjunction with "Use personal contacts, white list and black list files" above, the number of Spam Filter false positives can be drastically reduced.
If you do not wish to apply automatic white list updating to every MDaemon user then you can disable it for individual users by clearing the "
Update white listed contacts with mail recipients
" check box on the
657
screen of the Account Editor.
This option is disabled for accounts using autoresponders.
Remove contacts which are missing name or phone data
Click this button if you wish to remove every contact that contains only an email address from every user's default Contacts folder. If a contact doesn't have at least a name or phone data it will be removed. The option is primarily to help those who have been using MDaemon's automatic white listing option prior to version 11 purge contacts that were added purely as a function of the white list feature. In previous versions of MDaemon the addresses were added to the main contacts instead of to a dedicated white list folder. This could result in users having many entries in their contacts that they would rather not have there.
Consider this option carefully before using it, because contacts containing only an email address could still be legitimate.
Forwarding to whitelist@ updates whitelist contacts
When this option is enabled, accounts using the "
Spam Filter uses personal contacts, white list, and black list files
" on the Account Editor
' s Settings screen can forward messages to
whitelist@<domain>
and have MDaemon add the sender of the original message to the account's white list. The white listed address is taken from the forwarded message's
From
header.
Messages forwarded to
whitelist@<domain>
must be forwarded as attachments of the type
message/rfc822
, and they must be received by MDaemon via SMTP from a session that is authenticated. Forwarded messages not meeting these requirements will not be processed.
You can change the address MDaemon uses by editing the following key in the
CFILTER.INI
file:

" on the Account Editor
' s Settings screen can forward messages to
blacklist@<domain>
and have MDaemon add the sender of the original message to the account's black list. The black listed address is taken from the forwarded message's
From

Messages forwarded to

, and they must be received by MDaemon via SMTP from a session that is authenticated. Forwarded messages not meeting these requirements will not be processed.
Update Bayesian engine with copies of white listed messages
Check this box to cause qualified messages to be copied automatically into the
Bayesian non-spam learning folder (designated on the
478
screen). This helps to automate the process of providing the Bayesian engine with samples of non-spam messages. Regularly providing the Bayesian engine with new examples of non-spam to learn from will increase its reliability over time and help to reduce the number of false positives (i.e. messages that are erroneously classified as spam).
To qualify for this feature, an incoming message must be addressed to a local user and the sender must be someone in his address book file. If the message is outgoing, then it must be the recipient who is in the address book. If you do not want any outgoing messages to qualify, then use Notepad to edit the following setting in the
CFILTER.INI
file:
[SpamFilter]
UpdateHamFolderOutbound=No (default = Yes)
When a message qualifies, it is copied into the Bayesian non-spam learning folder even if Bayesian scheduled learning is disabled on the Bayesian screen. Thus, when scheduled learning is later enabled, or when learning is manually activated, a set of non-spam messages will be ready for analysis. Not every message that qualifies, however, is copied into the learning folder. When the feature is activated, MDaemon will copy qualified messages until a designated number is reached. Subsequently it will copy single messages at designated intervals. By default, the first 200 qualifying messages will be copied and then every tenth qualifying message after that. The initial number copied is equal to the number designated in the option, "Non-spam
samples needed before Bayesian scoring is possible" located on the
482
screen. Changing that setting will also change this value. If you wish to change the interval by which subsequent messages are copied, you can do so by editing the following setting in the
MDaemon.ini
file:
[SpamFilter]
HamSkipCount=10 (default = 10)
Finally, once a designated total number of messages has been copied, the entire process will be begin again — 200 will be copied and then every tenth (or an alternate value if you have changed these settings). By default, the process will be restarted after 500 qualifying messages have been copied. You can change this
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 489
value by editing the following setting in the
MDaemon.ini
file:
[SpamFilter]
HamMaxCount=500 (default = 500)
This option is unavailable when you have configured MDaemon to use another server's MDaemon Spam Daemon (MDSpamD) for Spam Filter processing. All Bayesian learning functions are determined by the other server's settings and are performed on the other server. See
484
for more information.
5.5.1.6 White List (no filtering)
Messages sent to these addresses are not filtered at all
Use this screen to designate recipient addresses that you wish to be exempt from spam filtering. Messages destined for these addresses will not be processed through the spam filter.
This screen is unavailable when you have configured MDaemon to use another server's MDaemon Spam Daemon (MDSpamD) for Spam Filter processing. This Spam Filter list will be

maintained on the other server. See
484
for more information.
5.5.1.7 White List (by recipient)
Messages sent to these addresses receive a beneficial score
This list is similar to
489
, except that rather than exempting messages for the recipient from Spam Filter processing, they will be processed but have their
474
reduced by the amount specified on the
495
screen. Therefore including an address on this white list does not automatically guarantee that a message to that address will not be considered spam. For example, if you have the spam score threshold set to 5.0 and the white list value set to 100, and then a particularly excessive spam message arrives that gets a spam score of 105.0 or higher before the white list value is subtracted, then the final spam score of the message will be at least 5.0, thus denoting it as spam.
This is highly unlikely, however, because spam rarely has a value that high unless it contains some other exceptionally high-scoring element, such as a blacklisted address.

5.5.1.8 White List (by sender)
Messages sent from these addresses receive a beneficial score
This white list is similar to
490
, except that spam score reduction is based on who the message is from rather than based on the recipient.
Messages from these senders will have their
474
reduced by the amount specified on the
495
screen. Therefore including an address on this white list does not automatically guarantee that a message to that address will not be considered spam. For example, if you have the spam score threshold set to 5.0 and the white list value set to 100, and then a particularly excessive spam message arrives that gets a spam score of 105.0 or higher before the white list value is subtracted, then the final spam score of the message will be at least 5.0, thus denoting it as spam.

5.5.1.9 Black List (by sender)
Messages sent from these addresses receive a detrimental score
Messages from addresses on this black list will have their
474 increased by the amount specified on the
495
screen, typically causing them to be marked as spam. However, including an address on this list does not automatically guarantee that a message from that address will always be considered spam. For example, if a message comes from a black listed sender but is addressed to a white listed recipient, then the score modifiers may offset each other and cause the message to have a final score that is below the spam score threshold. This could also happen if you have the black list score modifier set particularly low.

Reporting
Insert spam report into the headers of the original message
This is the default reporting option. Use this option if you want the Spam Filter to insert a spam report into each spam message
' s headers. The following is an example of a simple spam report:
X-Spam-Report: ---- Start Spam Filter results
5.30 points, 5 required;
* -5.7 -- Message-Id indicates the message was sent from MS Exchange
* 2.0 -- Subject contains lots of white space
* -3.3 -- Has a In-Reply-To header

* 0.1 -- BODY: HTML included in message
* 1.6 -- BODY: HTML message is a saved web page
* 2.0 -- Date: is 96 hours or more before Received: date
---- End of Spam Filter results
Create a new message and attach the original message to it
Choose this reporting option if you want spam to cause a new email message to be created containing the spam report. The original spam message will be included with it as a file attachment.
Same as above but attach the message as text/plain
Like the previous reporting option, this option will generate the spam report as a new message that includes the original spam message as a file attachment. The difference is that the original message will be attached using the text/plain MIME type. Because spam sometimes contains HTML code that is unique for each message and can potentially reveal to the spammer which email and IP address opened it, this method can prevent that from happening by converting the HTML code to plain text.

It is typical for spam messages to be fairly small since the usual goal of the spammers is to deliver as many messages as possible in the shortest amount of time.
If you want messages over a certain size to be exempt from spam filtering then specify the size (in KB) here. Use "0" if you want only very large messages to be exempt from spam filtering—only messages over 2MB will not be filtered.

Use this option if you wish to keep the Spam Filter white and black list entries in sorted sequence. Note: if you have added your own comments to the file (lines starting with #), enabling this option will sort these lines to the top of the file. This feature is disabled by default. If you enable the option, the sort will take place upon the next change to the white or black list file.

A white list match subtracts this many points from the spam score
Placing an address on the Spam Filter’s
490
or
491
screens does not automatically guarantee that a message to or from that address will not be considered spam. Instead, those white listed addresses will simply have the amount specified in this control subtracted from their spam scores.
For example, if you have the spam score threshold set to 5.0 and this value set to
100, and then a particularly excessive spam message arrives that gets a spam score of 105.0 or higher before the white list value is subtracted, then the final spam score of the message will be at least 5.0 — thus denoting it as spam. This would rarely happen, however, because spam rarely has a value that high unless it contains some other exceptionally high-scoring element, such as a blacklisted address. Of course, if you set the white list subtraction value to a much lower amount then it would occur much more frequently.
If you wish to cause messages addressed to certain recipients to bypass the Spam Filter completely rather than simply adjust their scores, include those recipient addresses on the
489
screen. You can also exclude messages from Spam Filter scoring based on the sender by using the options on the
486
screen.
A black list match adds this many points to the spam score
This value is added to the spam score of messages from addresses found on the
492
screen. As with the white list option above, including an address on the Spam Filter
' s black list doesn't guarantee that a message from that address will be considered spam. Instead, the value specified in this option will be added to the message
' s spam score, which will then be used to determine whether or not the message is spam.

Because some IP addresses can be blacklisted by mistake, you should exercise caution before choosing to refuse messages rather than simply flagging them.

Auto-filter black-listed mail into user's spam folder
Click this option and a "Junk E-mail" IMAP folder will be created for all future user accounts that you add to MDaemon. MDaemon will also create a mail filter for each of those users, which will search for the X-MDDNSBL-Result header and then place messages containing that header into the user

Auto-generating a Spam Folder and Filter for Each Account
MDaemon can automatically create a "Junk E-mail" IMAP mail folder for each account and generate a mail filter that will move messages into that folder whenever if finds the
X-MDDNSBL-Result
header. Whenever you click the Auto-filter black-listed mail into
user's spam folder option, you will be presented with the option to create the folder and accompanying filter for all accounts. Simply choose “yes” on the dialog to create the folders and filters. Although not foolproof, this is an easy and generally reliable way to help your users quickly identify spam email messages—it can effectively prevent spam email from being mixed in with all of their legitimate email. They will only occasionally need to review the contents of their spam folder just to make sure that an important message doesn't accidentally get put there (which may sometimes occur).
When creating the folders and filters for your accounts, if MDaemon finds that an account already has a filter that checks for the existence of the
X-MDDNSBL-Result
header then no action will be taken and no filter will be created for that account. If you want the name of the IMAP folder to be something other than "Junk E-mail", you can change the default setting by editing the Default spam folder name option located

5.5.3 Spam Honeypots
Spam Honeypots (located at S ecuri ty » S pam Fi lter » S pam H oneypots ) is for designating local email addresses purposely designed to collect spam. These spam honeypots are not valid MDaemon accounts or address aliases and should never be used for sending or receiving legitimate email. But, by posting a honeypot address to a news group, public mailing list, or other source from which spammers often farm addresses, you should begin to see incoming messages addressed to the spam honeypots — you could also pull addresses from other spam that you have received addressed to other invalid local addresses. Because honeypots will never receive legitimate email, all incoming messages addressed to them will always be routed directly to your
478
for processing. Further, the IP addresses of the sending servers can optionally be added to the
555
system, banning future connections from those addresses for a designated period of time. All of this helps increase the probability of identifying and blocking spam in the future.

5.6.1.2 Reverse Lookup
With the options on this screen, MDaemon can be configured to do a reverse lookup on the domain passed in the
HELO/EHLO
and
commands. When performing the lookups MDaemon will attempt to acquire all of the MX and A record IP addresses for the given domain. Then the IP of the server making the connection is compared to this list in an attempt to determine whether the sender might be using a forged identity.
Oftentimes the sending mail server
' s IP address will not match any known MX or A records for a given domain and yet still be delivering the mail legitimately. The purpose of the Reverse Lookup process is therefore not to exclude mail but to include as much information as possible in the log files, and to provide the means whereby the postmasters can act according to their own local policies regarding these suspicious
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
508 MDaemon Messaging Server 17.0
messages. To that end, an option exists that makes it possible for a special header to be inserted into all messages that do not pass a reverse lookup. The content filter system can then be used to determine the fate of messages containing the header.
You can also perform reverse lookups on pointer records (PTR) of incoming IP addresses. When using this option the connection can be aborted or a warning header inserted into the message if the incoming IP address does not match any PTR record.
Finally, it is generally agreed that accepting mail from sources that identify themselves by using a domain that does not exist should be optional. Therefore, a switch exists that makes it possible for you to refuse messages for which the reverse lookup process returns a "domain not found" message from the DNS server. In such cases, MDaemon will return a
451
error code, refuse to accept the message, and then allow the SMTP session to progress. However, should you wish to return a
501
error code, close the socket connection, or do both, other switches are provided for those purposes.
Trusted IP addresses and localhost (127.0.0.1) are always exempt from reverse lookups.
Perform PTR lookup on inbound SMTP connections
Enable this option if you want MDaemon to perform pointer record lookups on all inbound SMTP connections.
...send 501 and close connection if no PTR record exists (caution)
If this box is checked then MDaemon will send a
501
error code (syntax error in parameters or arguments) and close the connection if no PTR record exists for the domain.
...send 501 and close connection if no PTR record match
If this box is checked then MDaemon will send a
501
error code (syntax error in parameters or arguments) and close the connection if the result of a pointer record lookup fails to match.
Exempt authenticated sessions (lookup will defer until after MAIL)
Click this option if you wish to defer the PTR lookup on inbound SMTP connections until after the SMTP MAIL command in order to see whether or not the connection will use authentication.
Perform lookup on HELO/EHLO domain
Click this box if you want a lookup to be performed on the domain name that is reported during the
HELO/EHLO
portion of the session. The
HELO/EHLO
command is used by the client (sending machine) to identify itself to the server. The domain name passed by the client in this command is used by the server to populate the from
portion of the
Received
header.
Perform lookup on value passed in the MAIL command
Enabling this switch will cause a lookup to be performed on the domain name that is passed during the
command portion of the mail transaction. The address passed in the
command is supposed to be the reverse-path for the message, and is usually the mailbox from which the message is originating. Sometimes, however, it is the address to which error messages should be directed instead.

Security Menu 509
...send 501 and close connection on forged identification (caution)
Click this check box if you want a 501 error code to be sent and then the connection closed when the result of a lookup appears to be a forged identification.
When the result of a reverse lookup states that the server is using a forged identification, this result may frequently be incorrect. It is very common for mail servers to identify themselves with values that do not match their IP addresses.
This can be due to ISP limitations and restrictions and other legitimate reasons. For this reason, you should exercise caution before enabling this option. It is likely that using this option could result in your server refusing some legitimate messages.
Refuse to accept mail if a lookup returns no MX records (caution)
'
Check this box if you wish to refuse MAIL from domains that do not have MX records. This option is disabled by default and should be used with caution, because domains do not need MX records in order to exist, be valid, or send/ receive mail.
Refuse to accept mail if a lookup returns
' domain not found
'
When a lookup results in " domain not found
", enabling this option will cause the message to be refused with a
451
error code (Requested action aborted: local error in processing) and then the session will be allowed to progress normally to its conclusion.
...send 501 error code (normally sends 451 error code)
Enable this checkbox if you want the error code that is sent in response to a
"domain not found" result to be

(syntax error in parameters or arguments) instead of
451
.
...and then close the connection
Click this checkbox if you want the connection to be closed immediately instead of allowed to progress when " domain not found
" is the result of the reverse lookup.

5.6.2.1 IP Shield
The IP Shield, located under the S ecuri ty » S ecuri ty S etti ng s menu, is a list of domain names and matching IP addresses that will be checked during the
MAIL From
command during the SMTP session. An SMTP session claiming to be from someone at one of the listed domains will be honored only if it is coming from one of the associated IP addresses. For example, suppose your domain name is example.com and your local LAN computers use IP addresses in the range from 192.168.0.0 to 192.168.0.255. With this information you can setup the IP Shield to associate the domain name example.com
with the IP address range 192.168.0.* (wildcards are allowed). Thus anytime a computer connects to your SMTP server and states, "
MAIL FROM
", the SMTP session will continue only if the connecting computer has an IP address within the required range from 192.168.0.0 to
192.168.0.255.

If you enable both this option and the
IP Shield honors aliases
option below, messages to valid aliases will be accepted as well.
Do not apply IP Shield to authenticated sessions
When this control is active, the IP Shield restrictions will not apply to authenticated users. Mail will be accepted from an authenticated user regardless of the IP address from which he or she connects. Further, when a user doesn't authenticate and access is refused, the message returned to the SMTP client will be "Authentication required" in order to give the user a clue that he can fix the problem by configuring the mail client to use authentication before sending a message. This option is enabled by default.

IP Shield honors aliases
Enable this option if you want the IP Shield to honor address aliases when checking domain/IP address shields. The IP Shield will translate an alias to the true account to which it points and thus honor it if it passes the shield. Without this option enabled, the IP Shield will treat each alias as if it is an address independent of the account that it represents. Thus, if an alias

5.6.2.3 SPF Verification
Security Menu 517
MDaemon supports Sender Policy Framework (SPF) to help verify sending servers and protect against spoofing and phishing, which are two common types of email forgery in which the sender of the message attempts to make the message appear to be coming from someone else.
Many domains publish MX records in the Domain Name System (DNS) to identify the locations permitted to receive mail for them, but this doesn't identify the locations allowed to
send
mail for them. SPF is a means whereby domains can also publish sender records to identify those locations authorized to send messages. By performing an SPF lookup on incoming messages, MDaemon can attempt to determine whether or not the sending server is permitted to deliver mail for the purported sending domain, and consequently determine whether or not the sender
' s address may have been forged or
"spoofed".
Use the options on this screen to configure your server's SPF settings.
For more information on SPF, visit: http://spf.pobox.com
SPF Verification

Click this option if you want all mail forwarded by MDaemon to use a local address in the SMTP envelope. This helps reduce problems associated with forwarding.
Normally, forwarded messages are sent using the email address of the original sender and not the email address that is actually doing the forwarding. In some situations, using a local address may be necessary in order to prevent the receiving server from falsely identifying the forwarded message as having a "spoofed" address.
Maximum number of 'Void' lookups (must be at least 2)
This is the maximum number of void lookup results permitted in an SPF query before
MDaemon generates a permanent error. A Void lookup is one that results in "domain does not exist" or "no answers exist." This value must be a least "2".
5.6.2.4 DomainKeys Identified Mail
DomainKeys Identified Mail (DKIM) is a cryptographic email verification system that can be utilized to prevent spoofing (forging another person
' s email address in order to pose as a different message sender). Additionally, because most junk email (spam) messages contain spoofed addresses, DKIM can help greatly in the reduction of spam even though the specifications weren't specifically designed to be an anti-spam tool. DKIM can also be used to ensure the integrity of incoming messages, or ensure that the message hasn't been tampered with between the time it left the signing mail server and arrived at yours. In other words, with DKIM cryptographic verification the receiving server can be certain that the arriving message is from the server that signed it, and that no one changed that message in any way.
In order to ensure the validity and integrity of messages, DKIM uses a public and private key-pairs system. An encrypted public key is published to the sending server
' s
DNS records and then each outgoing message is signed by the server using the corresponding encrypted private key. For incoming messages, when the receiving server sees that a message has been signed, it will retrieve the public key from the sending server
' s DNS records and then compare that key with the message
' s cryptographic signature to determine its validity. If the incoming message cannot be verified then the receiving server knows it contains a spoofed address or has been tampered with or changed. A failed message can then be rejected, or it can be accepted but have its spam score adjusted.

the DNS record of the domain taken from the signature and then use that key to test the message’s DKIM signature to determine its validity.
If the signature passes the verification test, the message will continue on to the next step in the regular delivery process. Additionally, if the domain taken from the signature also appears on the

Authentication-Results header
Whenever a message is authenticated using SMTP AUTH, SPF, DomainKeys Identified
Mail, or DMARC, MDaemon will insert the Authentication-Results header into the message, listing the results of the authentication process. If MDaemon is configured to accept messages even when they fail authentication, then the Authentication-Results header will contain a code to identify the reason for the failure.
There is ongoing work via the Internet Engineering Task Force
(IETF) on this header and the authentication protocols mentioned in this section. You can find more information on this at the IETF web site, located at:
http://www.ietf.org/
.
DKIM Headers in Mailing List Messages
By default, MDaemon strips DKIM signatures from incoming list messages because those signatures can be broken by changes made to the message headers or content during list processing. If you would like MDaemon to leave signatures in list messages, you can configure it to do so by manually setting the following option in the
MDaemon.ini
file:
[DomainKeys]

5.6.2.4.2 DKIM Signing
Use the options contained on the DKIM Signing screen to configure MDaemon to sign eligible outbound messages using DKIM, and to define the criteria that will make a message eligible. You can also use this screen to designate selectors and generate corresponding public and private keys suitable for use with the DKIM specification. A default selector ("MDaemon") and a default public and private key are created for you automatically on startup. All keys are unique—they are never the same from one site to another, regardless of the selector specified. By default, keys are generated with a secure bit depth of 1024 bits.
DKIM Signing
Sign eligible outbound messages using DKIM
Click this option if you wish to use DomainKeys Identified Mail to cryptographically sign some outgoing messages. In order for a message to be signed, it must meet the criteria designated under the

received by MDaemon for delivery on an authenticated session. There is also a
Content Filter action, "
Sign with DKIM selector...
" that you can use to cause messages to be signed.
...sign mailing list messages
Click this check box if you wish to cryptographically sign all outgoing Mailing List messages. Because MDaemon will sign all mail to all of your lists, you do not need to use the "
Define which messages are eligible for signing
" option to authorize them for cryptographic signing.
Signing list mail requires content filter processing for each list message after "cracking" the list. This could affect server performance when dealing with large and highly active mailing lists.
Default selector
From the drop-down list, choose the selector whose corresponding public/private key pair you wish to use when signing messages. If you wish to create a new key pair with a different selector, type the desired selector name here and click "Create
new public and private keys" below. If you wish to sign some messages using an alternate selector, designate a specific selector under the "Define which messages
are eligible for signing" option, or create a Content Filter rule using the "
Sign with
DKIM selector...
" action.
Delete this selector
Click this button if you wish to delete a selector. Follow the on-screen instructions that appear.
Create new public and private keys
Click this button to generate a public/private key pair for the selector specified above. A public/private key pair will be generated for the selector, and the file dns_readme.txt
will be generated and automatically opened. This file contains example DKIM data that you will need to publish to your domain
' s DNS records listing your DKIM Policy and the public key for the designated selector. The file lists samples for both testing and not testing status, and for whether you are signing all messages or just some messages originating from your domain. If you are currently testing DKIM or this selector, then you will need to use the information contained in the Testing entries for either the Policy or the selector, depending on what you are testing. Otherwise you will need to use the Not Testing entries.
All keys are stored in
PEM
format, and all selectors and keys are stored under the
\MDaemon\Pem
folder in the following way:
\MDaemon\Pem\<Selector>\rsa.public - public key for this selector
\MDaemon\Pem\<Selector>\rsa.private - private key for this selector
The files contained in these folders are not encrypted or hidden, but they contain RSA private encryption keys that should never be accessed by anyone without permission. You

should therefore take steps to secure these folders and subfolders using your OS tools.
Define which messages are eligible for signing
If you have elected to sign eligible outbound messages, click this button to edit the
DKSign.dat
file, which contains the list of domains and addresses that MDaemon will use to determine whether or not a message should be signed. For each address listed you must designate whether or not the message should be
To
or
From
that address in order for it to qualify to be signed, or you can designate some other header such as "
Reply-To
" or "
Sender
". Optionally, you can designate a selector for each entry, which will be used when signing a message that matches that entry.
Finally, you can specify an optional signing domain to be used in the "d=" tag within the signature header. This can be useful, for example, when you have multiple subdomains signing messages. In such cases you could use the "d=" tag to tell the receiving servers to look for the DKIM keys in a single domain
' s DNS record, thus making it possible for you to manage all of the keys in one record rather than having to manage separate records for each sub-domain. Wildcards are permitted in domains and addresses.
All messages from local domains are eligible for signing
Use this option if you wish to make all messages from your local domains eligible for signing. If you use this option then you do not need to add any of your local domains to the eligibility list (i.e. the
DKSign.dat
file) unless you wish to designate a specific selector or "
d=
" tag to be used when signing a specific domain’s messages.
This option is enabled by default.

Signatures expire after [XX] days ("x=" tag, 7 days recommended)
If you wish to limit the number of days that a DKIM signature can be considered valid, activate this option and specify the desired number of days. Messages with expired signatures will always fail verification. This option corresponds to the signature's "

Signatures include creation time stamp (include t= tag)
When this option is enabled, the signature creation time stamp ("t=" tag) will be included in the signature. This is enabled by default.
Signatures include query method(s) (include q= tag)
By default this option is enabled. It causes the signature to include the query method tag (e.g. "q=dns").
Signatures include body length count (include l= tag)
Enable this option if you wish to include the body length count tag in DKIM signatures.
Signatures include original header content (include z= tag)
Click this option if you wish to include the "z=" tag in the DKIM signature. This tag will contain a copy of the message

signatures quite large.
Signatures include reporting requested (include r=y tag)
Enable this option if you wish include the r=y tag in your signed messages. The presence of this tag indicates to receiving servers who honor the tag that you wish to receive AFRF failure reports from them when they encounter messages purporting to be from your domain but fail DKIM verification. To receive these reports, however, you must also configure a DKIM reporting TXT record in your domain's DNS. See
RFC-6651:
Extensions to DomainKeys Identified Mail (DKIM) for Failure Reporting
, for syntax and instructions on how to do that. Since this option requires DNS changes, it is disabled by default.
Canonicalization
Canonicalization is a process whereby the message
' s headers and body are converted into a canonical standard and "normalized" before the DKIM signature is created. This is necessary because some email servers and relay systems will make various inconsequential changes to the message during normal processing, which could otherwise break the signature if a canonical standard was not used to prepare each message for signing. Currently there are two canonicalization methods used for
DKIM signing and verification: Simple and Relaxed. Simple is the strictest method, allowing little to no changes to the message. Relaxed is more forgiving than Simple, allowing several inconsequential changes.
Canonicalize headers using: Simple, Relaxed
This is the canonicalization method used for the message headers when signing the message. Simple allows no changes to the header fields in any way. Relaxed allows for converting header names (not header values) to lower case, converting one or more sequential spaces to a single space, and other innocuous changes. The default setting is "Simple."
Canonicalize body using: Simple, Relaxed
This is the canonicalization method used for the message body when signing the message. Simple ignores empty lines at the end of the message body—no other changes to the body are allowed. Relaxed allows for blank lines at the end of the message, ignores spaces at the end of lines, reduces all sequences of spaces in a single line to a single space character, and other minor changes. The default setting is "Simple."
DKIM Verification Settings
Verifier honors body length count (l= tag)
When this option is enabled, MDaemon will honor the body length count tag when it is found in an incoming message
' s DKIM signature. When the actual body length count is greater than the value contained in this tag, MDaemon will only verify the amount specified in the tag — the remainder of the message will remain unverified.
This indicates that something was appended to the message, and consequently that unverified portion could be considered suspect. When the actual body length count is less than the value contained in this tag, the signature will not pass verification
(i.e. it will receive a "
FAIL
" result). This indicates that some portion of the message was deleted, causing the body length count to be less than the amount specified in the tag.

Verifier requires signatures to protect the Subject header
Enable this option if you wish to require the DKIM signature of incoming messages to protect the Subject header.
Valid signatures from 'Approved List' domains add this to Spam Filter score:
The value specified here will be added to the Spam Filter score of any DKIM signed messages that receive a "Pass" result when the domain taken from the signature appears on the

5.6.2.5 DMARC
Domain-based Message Authentication, Reporting & Conformance (DMARC) is a specification designed to help reduce email message abuse, such as incoming spam and phishing messages that misrepresent their origins by forging the message's From: header. DMARC makes it possible for domain owners to use the Domain Name System
(DNS) to inform receiving servers of their DMARC policy, which is how they want those servers to handle messages that purport to be sent from their domain but cannot be authenticated as having actually come from it. This policy, which is retrieved by the receiving server via a DNS query while processing the incoming message, can state that the server should quarantine or reject messages that do not align with the policy, or take no action at all (i.e. let the message proceed normally). In addition to the policy, the domain's DMARC DNS record can also contain requests for the server to send DMARC reports to some, outlining the number of incoming messages purporting to be from that domain and whether or not they passed or failed authentication, and with details about any failures. DMARC's reporting features can be useful for determining the effectiveness of your email authentication procedures and how frequently your domain name is being used in forged messages.
Under the Sender Authentication section of the Security Settings dialog, there are three screens for configuring MDaemon's DMARC verification and reporting features:
DMARC Verification, DMARC Reporting, and DMARC Settings.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
528 MDaemon Messaging Server 17.0
DMARC Verification
533
As part of the DMARC verification process, MDaemon performs a DMARC DNS query on the domain found in the From: header of each incoming message. This is done to determine whether or not the domain uses DMARC, and if so, to retrieve its
529
, which contains its policy and other DMARC related information. Additionally,
DMARC utilizes
517
and
520
to validate each message and requires it to pass at least one of those tests in order to pass DMARC verification. If the message passes then it will proceed normally through the rest of MDaemon's delivery and filtering processes. If it fails, however, then the fate of the message is determined by a combination of the domain's DMARC policy and how you have configured MDaemon to deal with those messages.
If a message fails DMARC verification and the DMARC domain has a policy of "p=none" then no punitive action will be taken and normal message processing will continue.
Conversely, when the DMARC domain has a restrictive policy of "p=quarantine" or
"p=reject," MDaemon can optionally filter the message automatically to the receiving user's spam (i.e. junk e-mail) folder. You can also choose to have MDaemon reject the failed message completely when the domain is using the "p=reject" policy. Additionally for failed messages with restrictive policies, MDaemon will insert the "X-MDDMARC-Failpolicy: quarantine
" or "X-MDDMARC-Fail-policy: reject" header, depending on the policy. This makes it possible for you to use the Content Filter to perform some action based on the presence of those headers, such as sending the message to a specific folder for further scrutiny.
DMARC Verification is enabled by default and recommended for most MDaemon configurations.
DMARC Reporting
536
When MDaemon queries DNS for a DMARC record, the record may contain tags indicating that the domain owner wishes to receive DMARC aggregate or failure reports regarding messages claiming to be from that domain. The options on the DMARC
Reporting screen are for designating whether or not you are willing to send the requested types of reports, and for specifying the meta-data those reports should contain. Aggregate reports are sent daily at Midnight UTC and failure reports are sent per message, as each incident occurs that triggers the report. Reports are always sent as zipped XML file attachments, and there are various parsing tools available online that can make them easy for the recipients to view.
By default MDaemon does not send aggregate or failure reports. If you are willing to send either type of report, enable its corresponding options on the DMARC Reporting screen.
DMARC Settings
539
The DMARC Settings screen contains various options for including certain info in DKIM reports, logging DMARC DNS records, and updating the Public Suffix file used by
MDaemon for DMARC.
DMARC Verification and Mailing Lists
Because the purpose of DMARC is to ensure that the domain found in a message's
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 529
From:
header hasn't been forged, the sending server must be permitted to send messages on behalf of that domain. This can pose a unique problem for mailing lists, because it is common for lists to distribute messages on behalf of list members from outside domains, and yet leave the From: header unchanged. This means that when a receiving server attempts to use DMARC verification on one of these messages, the message will have been sent by a server that is not officially affiliated with the From: header domain. If the DMARC domain happens to be using a restrictive DMARC policy, this could cause the message to be quarantined or even rejected by the receiving server. In some cases this could also cause the recipient to be removed from the list's membership. To circumvent this problem, when MDaemon finds that a messages for a list is coming from a domain with a restrictive DMARC policy, MDaemon will replace the message's From: header with the mailing list's address. Alternatively, you can configure
MDaemon to refuse to accept any message for a list when it is from a domain with a restrictive policy. This latter option would effectively make it impossible for a user from a domain with a restrictive policy to post a message to the list. The option to replace the From: header is located on the mailing list editor's
224
screen. The option to reject messages is located on the
221
screen.
Using DMARC for Your MDaemon Domains
If you would like to use DMARC for one of your own domains, meaning that you want receiving mail servers that support DMARC to use DMARC to verify messages claiming to be from you, then you must first ensure that you have created properly formatted SPF and DKIM DNS records for the domain; you must have at least one of those options working correctly to use DMARC. If you are using DKIM then you must also configure
MDaemon's
522
options to sign the domain's messages. Additionally, you must create a DMARC DNS record for the domain. By querying DNS for this specially formatted TXT record, the receiving server can determine your DMARC policy and various optional parameters such as: the mode of authentication you use, whether or not you wish to receive aggregate reports, the email address to which reports should be sent, and others.
Once you have properly configured DMARC and have begun to receive DMARC XML reports, there are a variety of online tools you can use to read those reports and diagnose any potential problems. For your convenience there is also a DMARC Reporter tool provided for you in the \MDaemon\App\ folder. See DMARCReporterReadMe.txt for instructions on how to use it.
Defining a DMARC TXT Resource Record
The following is an overview of the most basic, commonly used components of a
DMARC record. For more detailed information, or for information on more advanced configurations, see: www.dmarc.org
.
Owner Field
The Owner (also called "Name" or "left-hand") field of the DMARC resource record must always be _dmarc, or it can take the form _dmarc.domain.name if you wish to specify the domain or subdomain to which the record applies.
Example:
DMARC record for the domain example.com
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
530 MDaemon Messaging Server 17.0
_dmarc IN TXT "v=DMARC1;p=none"
This record would apply to emails from [email protected] or any subdomains of example.com, such as [email protected], [email protected], and so on.
_dmarc.support.example.com IN TXT "v=DMARC1;p=none"
This record would only apply to emails from [email protected], not to emails from, for example, [email protected].
_dmarc.support IN TXT "v=DMARC1;p=none"
This record would apply to emails from: [email protected], [email protected], [email protected], and so on.
DMARC Record Tags and Values
Required Tags
Tag Value Notes v= DMARC1
The is the Version tag, which must be the first tag in the
DMARC specific text portion of the record. Although other
DMARC tag values are not case sensitive, the value of the
v= tag must have the uppercase value: DMARC1.
Example:
_dmarc IN TXT "v=DMARC1;p=none"
p= none quarantine reject
This is the Policy tag, which must be the second tag in the
DMARC record, following the v= tag.
p=none means that the receiving server should take no action based on results of the DMARC query. Messages that fail the DMARC check should not be quarantined or rejected based on that failure. They could still be quarantined or rejected for other reasons, such as for failing spam filter tests or other security checks unrelated to DMARC. Using
p=none is sometimes called "monitoring" or "monitor mode" because you can use it with the rua= tag to receive aggregate reports from recipient domains about your messages, but those messages will not be penalized by the domains for failing to pass the DMARC check. This is the policy to use until you have thoroughly tested your DMARC implementation and are sure you are ready to move on to the more restrictive p=quarantine policy.
p=quarantine is the policy to use when you want other mail servers to treat a message as suspicious when its
From: header says that it is coming from you but the message fails the DMARC check. Depending upon the server's local policy, this could mean subjecting the
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 531
message to additional scrutiny, placing it into the recipient's spam folder, routing it to a different server, or taking some other action.
p=reject indicates that you want the receiving server to reject any message that fails DMARC verification. Some servers, however, may still accept these message but quarantine them or subject them to additional scrutiny. This is the most restrictive policy and should generally not be used unless you have total confidence about your email policies and the types of messages or services you wish to allow your accounts to use. For example, if you wish to allow your users to join 3rd party mailing lists, use mail forwarding services, utilize "share this" features on websites, or the like, then using p=reject would almost certainly cause some legitimate messages to be rejected. It could also cause some users to be automatically dropped or banned from certain mailing lists.
Example:
_dmarc IN TXT "v=DMARC1;p=quarantine;rua=mailto:[email protected]"
Optional Tags
All of the tags listed below are optional. When any of these tags are not used in a record then their default values are assumed.
Tag Value sp= none quarantine reject
—
Default:
If sp= is not used, the p= tag applies to the domain and subdomain s.
Notes
This tag is for specifying a policy to be used for subdomains of the domain to which the DMARC record applies. For example, if this tag is used in a record that has scope over example.com, then the policy designated in the p= tag will apply to messages from example.com and the policy designated in the sp= tag will apply to messages from subdomains of example.com, such as mail.example.com. If this tag is omitted from the record, the p= tag will apply to the domain and its subdomains.

DMARC Verification
Enable DMARC verification and reporting
When this option is enabled, MDaemon will perform DMARC DNS queries on the domain found in the From: header of incoming messages, and it will send aggregate and failure reports if you have set it to do so on the
536
screen.
DMARC uses
517
and
520
to validate messages, therefore at least one of those features must be enabled before DMARC can be used. DMARC verification and reporting is enabled by default and should be used in most MDaemon configurations.
Disabling support for DMARC could allow an increase in spam, phishing, or otherwise forged messages getting to your users.
It could also cause some of your mailing list messages to be rejected by other servers and even cause some list members to be dropped from your lists. You should not disable DMARC unless you are absolutely sure that you have no need of it.
Do not verify messages from authenticated sessions
By default MDaemon will not perform DMARC queries on messages that are received over an authenticated session. Authenticated sessions include those verified by

, which can white list based on verified DKIM identifiers and SPF paths from sources you trust. So, for example, if a message arrives that fails the DMARC check but has a valid DKIM signature from a domain on the Approved List, the message is not subject to punitive DMARC policy (i.e..the
message is treated as if the policy were "p=none"). The same happens if SPF path verification matches a domain on the
Approved List.

DMARC Message Disposition
Honor p=reject when DMARC produces a 'FAIL' result
Enable this option if you wish to honor the p=reject DMARC policy when a message's From: domain has published that policy in its DMARC record and the message fails DMARC verification. Messages failing DMARC verification will be refused during the SMTP session.
This option is disabled by default, meaning that if the message fails DMARC verification then MDaemon will insert the "X-MDDMARC-Fail-policy: reject" header into the message instead of refusing to accept it. In that case you could use the Content Filter to perform some action based on the presence of that header, such as sending the message to a specific folder for further scrutiny. Further, you could use the "Filter messages which fail the DMARC test into spam folders" option below to cause the message to be placed into the recipient's spam folder.
Even if you leave this option disabled, the message could still be rejected for some other reason unrelated to DMARC, such as having a
474
above the permitted threshold.
Filter messages which fail the DMARC test into spam folders
Enable this option if you wish to filter messages automatically into the recipient account's spam (i.e. junk e-mail) folder whenever a message fails DMARC verification. If this folder doesn't yet exist for the user, MDaemon will create one when needed.
When enabled, this option is only applied when the From: domain has published a restrictive DMARC policy (i.e.
p=quarantine or p=reject). When the domain publishes a p=none policy then that indicates that the domain is only monitoring DMARC and no punitive measure should be taken.

5.6.2.5.2 DMARC Reporting
When MDaemon queries DNS for a DMARC record, the record may contain various tags indicating that the domain owner wishes to receive DMARC reports regarding messages claiming to be from that domain. The options on the DMARC Reporting screen are for designating whether or not you wish to send DMARC aggregate or failure reports to the domains whose DMARC records request them, and for specifying the meta-data those reports will contain. The options on this screen are only available when the "Enable
DMARC verification and reporting" option is enabled on the
533 screen. Further, the DMARC specification requires the use of
565
whenever it is offered by report receivers. You should therefore enable STARTTLS if possible.
DMARC Reporting
Send DMARC aggregate reports
Enable this option if you are willing to send DMARC aggregate reports to domains who request them. When a DMARC DNS query on an incoming message's From: domain indicates that its DMARC record contains the "rua=" tag (e.g.
rua=mailto:[email protected]
), then that means the domain owner wishes to receive DMARC aggregate reports. MDaemon will therefore store DMARC related information about the domain and about the incoming messages claiming to be from that domain. It will log the email addresses to which the aggregate report should be sent, the verification methods used for each message (SPF, DKIM, or both), whether or not the message passed or failed, the sending server, its IP address, the DMARC policy applied, and so on. Then, each day at Midnight UTC
MDaemon will use the stored data to generate each domain's report and send it to
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 537
the designated addresses. Once the reports are sent, the stored DMARC data is cleared and MDaemon will start the whole process again.
MDaemon does not support the DMARC report interval tag (i.e.
"ri=") for aggregate reporting. MDaemon will send aggregate reports each day at Midnight UTC, to any domain for which it has compiled DMARC data since the last time the DMARC reports were generated and sent.
Send aggregate reports now
Click this button if you wish to generate and send a batch of aggregate reports from the currently stored DMARC data, instead of waiting until MDaemon does so automatically at the next Midnight UTC batch event. This sends the reports immediately and clears the stored DMARC data, exactly like what happens each day at Midnight UTC. MDaemon will then begin storing DMARC data again until the next Midnight UTC event, or until you click the button again, whichever come first.
Because MDaemon must be running at Midnight UTC to send aggregate reports and clear stored DMARC data automatically, if you have MDaemon shut down at that time then no reports will be generated and the DMARC data will not be cleared.
DMARC data collection will continue whenever MDaemon is running again, but reports will not be generated and data will not be cleared until the next Midnight UTC event, or until you click the "Send aggregate reports now" button.
Send DMARC failure reports (reports are sent as incidents occur)
Enable this option if you are willing to send DMARC failure reports to domains who request them. When a DMARC DNS query on an incoming message's From: domain indicates that its DMARC record contains the "ruf=" tag (e.g. ruf=mailto:[email protected]
), then that means the domain wishes to receive DMARC failure reports. Unlike aggregate reports, these reports are created in real-time as the incidents which trigger them occur, and they contain extensive detail regarding each incident and the errors that caused the failure. These reports can be used for forensic analysis by the domain's administrators to correct problems with their email system configuration or identify other problems, such as ongoing phishing attacks.
The type of failure that will trigger a failure report is dependent upon the value of the "fo=" tag in the domain's DMARC record. By default a failure report will only be generated if all of the underlying DMARC checks fail (i.e. both SPF and DKIM fail), but domains can use various "fo=" tag values to indicate that they wish to receive the reports only if SPF fails, only if DKIM fails, if either fail, or some other combination. Consequently, multiple failure reports can be generated from a single message depending upon the number of recipients in the DMARC record's "ruf=" tag, the value of the "fo=" tag, and number of independent authentication failures that are encountered for the message during processing. If you wish to limit the number of recipients to which MDaemon will send any given report, use the "Honor up to this
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
538 MDaemon Messaging Server 17.0
many DMARC 'rua' and 'ruf' recipients" option below.
For the report format, MDaemon will only honor the rf=afrf tag ( Authentication
Failure Reporting Using the Abuse Reporting Format ), which is the DMARC default. All reports are sent in this format, even if a domain's DMARC record contains the rf=iodef
tag.
In order to support DMARC failure reporting, MDaemon fully supports: RFC 5965: An Extensible Format for Email Feedback
Reports , RFC 6591: Authentication Failure Reporting Using the
Abuse Reporting Format , RFC 6652: Sender Policy Framework
(SPF) Authentication Failure Reporting Using the Abuse
Reporting Format , RFC 6651: Extensions to DomainKeys
Identified Mail (DKIM) for Failure Reporting , and RFC 6692:
Source Ports in Abuse Reporting Format (ARF) Reports .
When the DMARC "fo=" tag requests reporting of SPF related failures, MDaemon sends SPF failure reports according to RFC
6522. Therefore, that specification's extensions must be present in the domain's SPF record. SPF failure reports are not sent independent of DMARC processing or in the absence of
RFC 6522 extensions.
When the DMARC "fo=" tag requests reporting of DKIM related failures, MDaemon sends DKIM failure reports according to RFC
6651. Therefore, that specification's extensions must be present in the DKIM-Signature header field, and the domain must publish a valid DKIM reporting TXT record in DNS. DKIM failure reports are not sent independent of DMARC processing or in the absence of RFC 6651 extensions.
Honor up to this many DMARC 'rua' and 'ruf' recipients (0 = no limit)
If you wish to limit the number of recipients to which MDaemon will send any given
DMARC aggregate report or DMARC failure report, specify the maximum number here.
If a DMARC record's "rua=" or "ruf=" tag contains more addresses than your designated limit, then MDaemon will send a given report to the listed addresses, in order, until the maximum number of addresses is reached. By default there is no limit set.
Email a copy of all reports to:

5.6.2.6 Message Certification
Message Certification is a process by which one entity vouches for or "certifies" the good email conduct of another entity. Consequently, when this certifying entity is one whom a receiving email server trusts, messages sent from a domain who is vouched for by that entity can be viewed with less suspicion. Thus the receiving server can be reasonably assured that the sending domain adheres to a set of good email practices and doesn't send spam or other problematic messages. Certification is beneficial because it can help ensure that messages will not be erroneously or needlessly subjected to unwarranted spam filter analysis. It also helps lower the resources required to process each message.
MDaemon Pro supports Message Certification by including the world's first commercial implementation of a new Internet mail protocol called "Vouch-By-Reference" (VBR), which Alt-N Technologies is working to help create and expand through its participation in the Domain Assurance Council (DAC). VBR provides the mechanism through which
Certification Service Providers (CSP) or "certifiers" vouch for the good email practices of specific domains.
Certifying Incoming Messages
It is easy to configure MDaemon's Message Certification feature to check incoming messages. All you have to do is click the Enable certification of inbound messages option on the VBR Certification dialog (S ecuri ty » S ecuri ty S etti ng s » S ender
A uthenti cati on » VBR Certi fi cati on) and include one or more certification providers whom you trust to vouch for incoming email (e.g.
vbr.emailcertification.org
).
You can also choose either to exempt certified messages from spam filtering or give their Spam Filter scores a beneficial adjustment.
Certifying Outgoing Messages
Before you can configure MDaemon to insert certification data into your outgoing messages, you will first need to arrange to have one or more CSPs certify your email.
Alt-N Technologies provides a certification service for MDaemon customers. For details, visit:
www.altn.com
.
To configure your MDaemon server to use Message Certification with your outgoing mail, after you have registered with a CSP:
1. Open the VBR Certification dialog: click S ecuri ty » S ecuri ty S etti ng s » S ender
A uthenti cati on » VBR Certi fi cati on.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
542 MDaemon Messaging Server 17.0
2. Click "Insert certification data into outgoing messages."
3. Click "Configure a domain for message certification." This opens the Certification
Setup dialog.
4. Type the Domain name whose outgoing messages will contain the certification data.
5. Use the Mail type drop-down list to choose the type of email that your CSP agrees to certify for this domain, or enter a new type if the desired type isn't listed.
6. Enter one or more CSPs who will certify the domain's outbound email. If you have more than one CSP then use a space to separate each one.
7. Click "OK."
8. Configure your server to sign the domain's outgoing messages with
519
, or ensure that they are being sent from an
517
approved server. This is necessary in order to guarantee that the message originated from you. A message cannot be certified unless the receiving server can first determine that the message is authentic.
VBR does not require the certified messages to be signed by or transmitted to your CSP. The CSP is not signing or validating specific messages—it is vouching for the domain's good email practices.

Certified messages apply this many points to the spam filter score
If you do not wish to exempt certified messages from spam filtering, use this option to designate the amount by which you wish to adjust the message's Spam Filter score. Ordinarily this should be a negative number so that certified messages will receive a beneficial adjustment. The default setting is "

5.6.2.7 Approved List
Because some spammers and senders of bulk email have begun using SPF or signing messages with a valid DKIM signature, the fact that a message is signed and verified is no guarantee that you won
' t consider it to be spam, even though it does ensure that the message originated from a valid source. For this reason, a message
' s spam score will not be lowered as a result of SPF or DKIM verification unless the domain taken from the signature is on the Approved List. This is essentially a white list that you can use to designate domains permitted to have their messages
'
spam scores reduced when those incoming messages are verified.
When a message signed by one of these domains is verified by SPF or DKIM, its spam score will be reduced according to the settings found on the
517
and
520
screens. You can, however, append any of the flags listed below if you wish to prevent either of those verification methods from reducing the score. There is also a flag that you can use to prevent verified messages from being passed through the Spam Filter.

So, for example, if a message arrives that fails the DMARC check but has a valid DKIM signature from a domain on the Approved List, the message is not subject to punitive DMARC policy
(i.e..the message is treated as if the policy were "p=none"). The same happens if SPF path verification matches a domain on the Approved List.

5.6.3.5 Dynamic Screen
Security Menu 555
Using the Dynamic Screening features, MDaemon can track the behavior of sending servers to identify suspicious activity and then respond accordingly. For example, you can temporarily block an IP address from future connections to your server once a specified number of "unknown recipient" errors occur during the mail connection from that IP address. You can also block senders that connect to your server more than a specified number of times in a specified number of minutes, and senders that fail authentication attempts more than a designated number of times.
When a sender is blocked, it is not permanent. The sender's IP address will be blocked for the number of minutes that you have specified on this dialog. Blocked addresses are contained in the
DynamicScreen.dat
file. It contains a list of the blocked IP addresses and the length of time each will be blocked. This file is memory resident and can be changed from the
Advanced
button. If you wish to edit or add the IP addresses manually using a text editor, you should create the
DynamicScreenUpd.sem
772
and place it in MDaemon's
\APP\
folder rather than editing the
DynamicScreen.dat
file directly.
The "Dynamic screening (WorldClient)" section provides options that allow you to screen WorldClient connections.
Enable Dynamic Screening (SMTP, POP, & IMAP)
Click this check box to enable dynamic screening. This option screens SMTP, POP3, and IMAP connections.

Block IPs that connect more than [X] times in [X] minutes
Click this check box if you wish to temporarily block IP addresses that connect to your server an excessive number of times in a limited time period. Specify the number of minutes and the number of connections allowed in that period.
Block IPs that fail this many authentication attempts
Use this option if you wish to temporarily block IPs that fail an authentication attempt a specified number of times. This can help prevent attempts to "hack" a user account and falsely authenticate a session. This option monitors SMTP, POP3, and IMAP connections. The database of failed authentication attempts is reset at midnight each night.
...but not when they use the same password every time
By default Dynamic Screening will not block IP addresses for failing too many authentication attempts when each of the failed attempts uses the same password. This is to prevent a legitimate client from having its IP address blocked due to the client not yet being configured with a new password. Disable this option if you wish to block an IP address even when all failed attempts used the same password.
Limit simultaneous connections by IP to (0 = no limit)
This is the maximum number of simultaneous connections allowed from a single IP address before it will be blocked. Use "0" if you do not wish to set a limit.
Block IPs that cause this many failed RCPTs
When an IP address causes this number of "Recipient unknown" errors during a mail session it will be automatically blocked for the number of minutes specified in the
Block IPs for this many minutes
option below. Frequent "Recipient unknown" errors are often a clue that the sender is a spammer, since spammers commonly attempt to send messages to outdated or incorrect addresses.
Block IPs that send this many RSETs (0 = no limit)
Use this option if you wish to block any IP address that issues the designated number of RSET commands during a single mail session. Use "0" if you do not wish to set a limit. There is a similar option on the
85
screen under Server Settings that can be used to set a hard limit on the allowed number of RSET commands.
Block IPs and senders for this many minutes
When an IP address or sender is automatically blocked, this is the number of minutes the block will last. When the block expires the IP or sender will be able to send to you again normally. This feature prevents you from accidentally blocking a valid IP address or sender permanently.
Close SMTP session after blocking IP
Enabling this option causes MDaemon to close the SMTP session after the IP address is blocked.

Maximum authentication failures allowed in a mail session
This is the maximum number of failed authentication attempts allowed in a mail session before the actions below (if any) are taken. This is set to 10 by default.
Freeze accounts that exceed the max authentication failures allowed
Check this box if you wish to freeze accounts that fail more than the designated number of authentication attempts. If an account is frozen an email is always sent to the postmaster. Replying to that email will re-enable the account.
...but not when they use the same password every time
When you elect to "Freeze accounts that exceed the max authentication
failures allowed," by default MDaemon will not freeze the account when each of the failed attempts uses the same password. This is to prevent a legitimate client from causing the account to be frozen when the client has simply not yet being updated with a new password. Disable this option if you wish to freeze accounts even when all failed attempts use the same password.
Notify postmaster when max authentication failures reached
Check this box if you wish to send a notification email to the postmaster whenever an account fails the designated number of authentication attempts.
Sources to include in notification: SMTP, POP, IMAP
Use this option to designate the source protocols that will trigger authentication failure notifications: SMTP, POP, or IMAP. If, for example, you don't wish to be notified of SMTP authentication failures, leave the SMTP option unchecked. You would then only receive the authentication failure emails for POP and IMAP failures.

5.6.3.6 Hijack Detection
Security Menu 559
Account Hijack Detection
The options on this screen can be used to detect a possibly hijacked MDaemon account and automatically prevent it from sending messages through your server. For example, if a spammer somehow obtained an account's email address and password then this feature could prevent the spammer from using the account to send bulk junk e-mail through your system. You can designate a maximum number of messages that may be sent by an account in a given number of minutes, based on the IP address from which it is connecting. You can also choose to disable accounts that reach the limit.
There is also a White List that can be used to exempt certain addresses from this restriction. Account Hijack Detection is enabled by default.
Account Hijack Detection only applies to local accounts over authenticated sessions, and the Postmaster account is automatically exempt.
Limit messages sent from reserved IPs to [xx] msgs in [xx] minutes
Use this option to prevent MDaemon accounts connecting from reserved IPs from sending more than the specified number of messages in the designated number of minutes. Reserved IP addresses are mostly as defined by RFCs (for example,
127.0.0.*, 192.168.*.*, 10.*.*.*, 172.16.0.0/12, ::1, FD00::/8, FEC0::/10, and
FE80::/64).
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
560 MDaemon Messaging Server 17.0
Limit messages sent from local IPs to [xx] msgs in [xx] minutes
Use this option to prevent MDaemon accounts connecting from any local IPs from sending more than the specified number of messages in the designated number of minutes. Local IPs are all IP addresses configured for any of your MDaemon domain.
Limit messages sent from all other IPs to [xx] msgs in [xx] minutes
Use this option to prevent MDaemon accounts connecting from any other IPs from sending more than the specified number of messages in the designated number of minutes.
Limit access to [xx] connections from differing IPs in [xx] minutes
Use this option to limit the number of connections from different IP addresses allowed within the specified number of minutes. For example, in normal circumstances if your account is accessed from ten different IP addresses within just a few minutes, it is likely the account has been hijacked. This option is disabled by default.
Include LAN IPs when limiting local IPs
By default
593
are included when using the "Limit messages sent from local
IPs..." option above. Uncheck this box if you do not wish to include LAN IPs when limiting local IPs.
Send 5XX when limit is reached (otherwise 4XX)
By default when one of the limits is reached, MDaemon will send a 5XX reply code to the hijacked account. Disable this option if you wish to send a 4XX code instead.
Freeze accounts when limit is reached
Check this box if you wish to freeze accounts that attempt to send more than the allowable number of messages. When this happens, the server sends a 552 error, the connection is dropped, and the account is immediately frozen. The frozen account will no longer be able send mail or check its mail, but MDaemon will still accept incoming mail for the account. Finally, when the account is frozen an email is then sent to the postmaster about the account. If the postmaster wishes to reenable the account, he can simply reply to the message.
White List
Use the White List to designate any addresses that you wish to exempt from
Account Hijack Detection. Wildcards are permitted. For example,
"[email protected]" would exempt example.com's "newsletters" MDaemon account, while "*@newsletters.example.com" would exempt all MDaemon accounts belonging to the newsletters.example.com domain. The Postmaster account is automatically exempt from Account Hijack Detection.
From Header Modification
This security feature modifies the "From:" header of incoming messages to cause the name-only portion of the header to contain both the name and email address. This is done to combat a common tactic used in spam and attacks where the message is made
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 561
to appear to be coming from someone else. When displaying a list of messages, email clients commonly display only the sender's name rather than the name and email address. To see the email address, the recipient must first open the message or take some other action, such as right-click the entry, hover over the name, or the like. For this reason attackers commonly construct an email so that a legitimate person or company name appears in the visible portion of the "From:" header while an illegitimate email address is hidden. For example, a message's actual "From:" header might be,
"Honest Bank and Trust" <[email protected]>, but your client might display only "Honest Bank and Trust" as the sender. This feature changes the visible portion of the header to display both parts, with the email address given first. In the above example the sender would now appear as
"[email protected] -- Honest Bank and Trust,"
giving you a clear indication that the message is fraudulent.
Enable From header modification
Enable this option if you wish to modify the client-visible portion of the "From:" header of incoming messages to include both the name and email address of the sender. The construction of the new header will change from "Sender's Name"
to "[email protected] -- Sender's Name"
. This only applies to messages to local users, and this option is disabled by default. Consider carefully before enabling this option as some users may neither expect nor want the From: header to be modified, even if it might help them identify fraudulent emails.

5.6.3.7 Spambot Detection
Spambot Detection tracks the IP addresses that every SMTP MAIL (return-path) value uses over a given period of time. If the same return-path is used by an inordinate number of different IP addresses in a short time, this could indicate a spambot network.
When a spambot is detected, the current connection is immediately dropped and the return-path value is optionally blacklisted for a length of time you specify You can also optionally blacklist all the known spambot IP addresses for a designated period.
Enable Spambot Detection
Click this box to enabled Spambot detection. It is disabled by default.

SMTP response (leave blank for default)
Use this option if you wish to customize the SMTP response to spambots attempting to send messages from a blacklisted return-path or IP address. MDaemon will return the SMTP response, "551 5.5.1 <your custom text>", rather than the default response. Leave it blank to use MDaemon's default response.
Do not track connections if they are authenticated
By default MDaemon will not track
515
sessions for Spambot Detection.

5.6.4 SSL & TLS
MDaemon supports the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocol for SMTP, POP, and IMAP, and for WorldClient's web server. The SSL protocol, developed by Netscape Communications Corporation, is the standard method for securing server/client Internet communications. It provides server authentication, data encryption, and optional client authentication for TCP/IP connection. Further, because
SSL is built into all current major browsers, simply installing a valid digital certificate on your server will activate the connecting browser
' s SSL capabilities when connecting to
WorldClient.
If you are connecting to the standard mail ports via a mail client instead of using
WorldClient, MDaemon supports the STARTTLS extension over TLS for SMTP and IMAP, and the STLS extension for POP3. However, you must first have your client configured to use SSL, and it must support those extensions—not all mail clients support them.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
564 MDaemon Messaging Server 17.0
Finally, you can also dedicate specific ports for SSL connections. This isn't required but can provide a further level of accessibility for clients that do not support certain SSL extensions. For example, some versions of Microsoft Outlook Express don't support
STARTTLS for IMAP over the default mail port, but do support connections to dedicated SSL ports.
The options for enabling and configuring SSL are located under the SSL & TLS section of the Security Settings dialog at: S ecuri ty » S ecuri ty S etti ng s » S S L & T L S . The SSL port settings for SMTP, POP3, and IMAP are located on the
88

Using Let's Encrypt to Manage Your Certificate
To support
563
for
565
,
568
, and
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
572 MDaemon Messaging Server 17.0
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

HTTPS port
This is the TCP port that Remote Administration will listen to for SSL connections.
The default SSL port is 443. If the default SSL port is used, you will not have to include the port number in Remote Administration

This is not the same as the Remote Administration port that is designated on the

Alternative host names (separate multiple entries with a comma)
MDaemon does not support multiple certificates — all Remote Administration domains must share a single certificate. If there are alternative host names to which users may be connecting and you want this certificate to apply to those names as well, enter those domain names here separated by commas. Wildcards are permitted, so
"
*.example.com
" would apply to all sub domains of
example.com

Using Let's Encrypt to Manage Your Certificate
To support
563
for
565
,
568
, and
572
, you need an SSL/TLS Certificate. Certificates are small files issued by a Certificate Authority (CA) that are used to verify to a client or browser that it is connected to its intended server, and that enable SSL/TLS/HTTPS to secure the connection to that server. Let's Encrypt is a CA that provides free certificates via an automated process designed to eliminate the currently complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.
To support using Let's Encrypt's automated process to manage a certificate, MDaemon includes a PowerShell script in the "MDaemon\LetsEncrypt" folder. A dependency of the script, the ACMESharp module, requires PowerShell 3.0
, which means the script will not work on Windows 2003. Additionally, WorldClient must be listening on port 80 or the
HTTP challenge cannot be completed and the script will not work. You will need to correctly set the execution policy for PowerShell before it will allow you to run this script. Running the script will set up everything for Let's Encrypt, including putting the necessary files in the WorldClient HTTP folder to complete the http-01 challenge. It uses the
154
of the
152
as the domain for the certificate, retrieves the certificate, imports it into Windows, and configures MDaemon to use the certificate for MDaemon, WorldClient, and Remote Administration.
If you have an
154
setup for your default domain that does not point to the
MDaemon server, this script will not work. If you want to setup alternate host names in the certificate, you can do so by passing the alternate host names on the command line.
Example usage:
..\LetsEncrypt.ps1 -AlternateHostNames mail.domain.com,wc.domain.com -
IISSiteName MySite -To "[email protected]"
You do not need to include the FQDN for the default domain in the
AlternateHostNames
list. For example, suppose your default domain is "example.com" configured with an FQDN of "mail.example.com", and you want to use an alternate
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
576 MDaemon Messaging Server 17.0
host name of "imap.example.com". When you run the script, you will only pass
"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one. If the challenges are not all completed then the process will not complete correctly. If you do not want to use any alternate host names then do not include the –AlternateHostNames parameter in the command line.
If you are running WorldClient via IIS, you will need to pass this script the name of your site using the -IISSiteName parameter. You must have Microsoft's Web Scripting tools installed in order for the certificate to be automatically setup in IIS.
Finally, the script creates a log file in the "MDaemon\Logs\" folder, called
LetsEncrypt.log
. This log file is removed and recreated each time the script runs.
The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

5.6.4.6 Creating and Using SSL Certificates
When using the SSL & TLS dialog to create certificates, MDaemon generates certificates that are self-signed. In other words, the issuer of the certificate, or
Certificate Authority (CA), is the same as the owner of the certificate. This is perfectly valid and allowed, but because the CA won't already be listed in yours users
'
lists of trusted CAs, whenever they connect to WorldClient or Remote Administration
' s HTTPS
URL they will be asked whether or not they wish to proceed to the site and/or install the certificate. Once they agree to install the certificate and trust your WorldClient
' s domain as a valid CA they will no longer have to see the security alert message when connecting to WorldClient or Remote Administration.
When connecting to MDaemon via a mail client such as Microsoft Outlook, however, they will not be given the option to install the certificate. They will be allowed to choose whether or not they wish to continue using the certificate temporarily, even
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 579
though it isn't validated. Each time they start their mail client and connect to the server, they will have to choose to continue using the non-validated certificate. To avoid this you can either obtain a certificate from a Certificate Authority, such as Let's
Encrypt , or you can export your self-signed certificate and distribute it to your users via email or some other means. Then, they can manually install and trust your certificate to avoid future warning messages.
Creating a Certificate
To create a certificate from within MDaemon:
1. Move to the SSL & TLS dialog within MDaemon (click Security » Security
Settings » SSL & TLS » MDaemon).
2. Check the box labeled, Enable SSL, STARTTLS, and STLS.
3. Click Create Certificate.
4. In the text box labeled, Host name, enter the domain to which the certificate belongs (for example, "mail.example.com").
5. Type the name of the organization or company that owns the certificate into the text box labeled, "
Organization/company name
".
6. In "
Alternative host names...
," type all other domain names that your users will be using to access your server (for example, "
*.example.com
", "
example.com
",
" mail.altn.com
", and so on).
7. Choose a length for the encryption key from the drop-down list box.
8. Choose the Country/region where your server resides.
9. Click
OK
.
Using Certificates Issued by a Third-party CA
If you have purchased or otherwise generated a certificate from some source other than MDaemon, you can still use that certificate by using the Microsoft Management
Console to import it into the certificate store that MDaemon uses. To do so in Windows
XP:
1. On your Windows toolbar, click S tar t » Ru n ... and then type "
mmc /a
" into the text box.
2. Click OK.
3. In the Microsoft Management Console, click F ile » Ad d /Remove S n ap -in ... on the menu bar (or press Ctr l+ M on your keyboard).

"imap.example.com" as an alternate host name. Further, if you pass alternate host names, an HTTP challenge will need to be completed for each one.

The log includes the starting date and time of the script but not the date and time stamp for each action. Also, notification emails can be sent when an error occurs. This is done using the $error variable, which is automatically created and set by
PowerShell. If you do not wish to have email notifications sent when an error occurs, do not include the –To parameter in the command line.

5.6.5.1 Backscatter Protection - Overview
Backscatter
"Backscatter" refers to response messages that your users receive to emails that they never sent. This occurs when spam messages or messages sent by viruses contain a
"Return-Path" address that is forged. Consequently, when one of these messages is rejected by the recipient's server, or if the recipient has an Autoresponder or "out of office"/vacation message associated with his account, the response message will then be directed to the forged address. This can lead to huge numbers of bogus Delivery
Status Notifications (DSNs) or auto response messages ending up in your users' mailboxes. Further, spammers and virus authors frequently take advantage of this phenomenon and will sometimes use it to launch Denial of Service (DoS) attacks against email servers, causing a flood of invalid emails to arrive from servers located all over the world.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
582 MDaemon Messaging Server 17.0
MDaemon's Solution
To combat backscatter, MDaemon contains a feature called Backscatter Protection
(BP). BP can help to ensure that only legitimate Delivery Status Notifications and
Autoresponders get delivered to your accounts, by using a private key hashing method to generate and insert a special time-sensitive code into the "Return-Path" address of your users' outgoing messages. Then, when one of these messages encounters a delivery problem and is bounced back, or when an auto-reply is received with a
"
mailer-daemon@...
" or
NULL
reverse path, MDaemon will see the special code and know that it is a genuine automated reply to a message that was sent by one of your accounts. If the address doesn't contain the special code, or if the code is more than seven days old, it will be logged by MDaemon and can be rejected.
583
is located under MDaemon's Security menu at: S ecuri ty »

Backscatter Protection is an implementation of Bounce Address Tag Validation (BATV).

5.6.5.1.1 Backscatter Protection
Security Menu 583
Backscatter Protection
Enable Backscatter Protection
Click this checkbox if you wish to insert a special Backscatter Protection code into each outgoing message's "Return-Path" address. MDaemon will generate this special code by using the private key found in the
rsa.private
file located in MDaemon's
PEM\_batv\
folder, and the code will be valid for seven days. Any incoming DSNs or other auto-response messages (with a "
mailer-daemon@...
" or
NULL
reverse path) must have a valid, non-expired BP code or they will fail BP verification.
If you disable this option, MDaemon will not insert the special
Backscatter Protection code into outgoing messages. It will, however, continue to check incoming DSNs and auto-response messages to ensure that any incoming message with a valid code is not rejected by mistake.
Apply Backscatter Protection to gateway domains
When Backscatter Protection is enabled, click this option if you also wish to apply it to domains for which MDaemon is acting as a gateway or backup server
(see
193
).

Reject messages that fail Backscatter Protection verification
Click this checkbox if you wish to reject DSNs or other auto-response messages that fail BP verification. Messages with a "
mailer-daemon@...
" or
NULL
reverse path will fail if they do not contain the special code or if the code's seven day life-cycle has expired. Because of Backscatter Protection's solid reliability, there are no false positives or "gray areas" — a message is valid or it isn't. For this reason it is safe to configure MDaemon to reject invalid messages, as long as you ensure that all of your accounts' outgoing messages contain the special BP code. In all cases, however, the result of BP verification will be logged into the SMTP-in log file, even when you choose not to reject messages that fail verification. Incoming messages for gateways will not be rejected unless you have checked the ...apply Backscatter
Protection to gateway domains option above.
When you enable Backscatter Protection, you should wait about a week before setting it to reject invalid auto-response messages. This is because during that time you might still receive DSNs or auto-responses to messages that were sent out before BP was activated. If BP were configured to reject invalid message during that time then those legitimate response messages would be rejected by mistake. After a week it should be safe to start rejecting invalid messages. This same warning applies when you create a new BP key and choose to delete the old key immediately instead of allowing it to continue working for another seven days. (see the Create
new Backscatter Protection key option below).
White List
Click this button to open the Backscatter Protection white list. Use this list to designate any IP addresses or domains that you wish to exempt from
Backscatter Protection.
Create new Backscatter Protection key
Click this button to generate a new Backscatter Protection key. This key is used by
MDaemon to create and then verify the special BP codes that are inserted into messages. The key is located in a file called
rsa.private
in MDaemon's
PEM\_batv\
folder. When the new key is generated, a box will open to inform you that the old key will continue to work for seven more days unless you wish to delete it immediately. In most cases you should click "N o", electing to allow the key to work for seven more days. If you choose to delete the key immediately then that could cause some incoming messages to fail BP verification, since they would be responses to messages containing the special code generated by the old key.
If you have your email traffic split across multiple servers, you may need to share the key file with all of your other servers or
Mail Transfer Agents (MTAs).

5.6.5.2 Bandwidth Throttling - Overview
The Bandwidth Throttling feature makes it possible for you to police the consumption of bandwidth used by MDaemon. You can control the rate at which sessions or services progress — you can set different rates for each of MDaemon
' s major services on a perdomain basis, including the Domains and Domain Gateways. You can also set limits on local connections by selecting "Local traffic" from a drop down box. This will allow you to create special bandwidth settings that will take effect if the connection is either from or to a local IP address or domain name.
Bandwidth Throttling can be applied on either a per-session or per-service basis. When using the per-session mode, each session will be independently throttled to the associated rate. Thus multiple sessions of the same service type occurring simultaneously could exceed a service
' s configured value. When configured to throttle bandwidth on a per-service basis, MDaemon will monitor the combined use of all sessions of the same service type and allocate equal fractions of the total bandwidth to each. Multiple sessions will then share the configured maximum bandwidth equally.
This will allow you to set a limit on an entire service.
When extending Bandwidth Throttling to a Domain Gateway, it must be handled a bit differently than a normal domain since a Domain Gateway doesn't have a specific IP address associated with it. MDaemon must use the value passed in the RCPT command to determine whether or not an inbound SMTP session is bound for the gateway. If it is, then inbound SMTP bandwidth throttling will be applied. Due to the limitations of
SMTP, if even one recipient of a multiple recipient message is destined for a Domain
Gateway then the entire session will be throttled.
The Bandwidth Throttling system is calibrated in kilobytes per second (KB/s). A value of
"0" means that no limit will be applied to the speed at which a session (or service) progresses, thus it will use the maximum amount of available bandwidth. A value of
"10", for example, will force MDaemon to deliberately throttle back on the speed of transmission so as to remain at or slightly above 10 KB/s.
Bursts of activity at the beginning of a session can and will exceed the fixed limits.
Throttling takes place and becomes more defined as the session progresses.

Configure settings for domain
Choose a domain from the drop-down list box and then adjust the options corresponding to the various services to configure bandwidth throttling for the selected domain. A setting of "0" in any particular control means no bandwidth limit is set for that service type. In the drop-down list box, the bottom entry listed is
Local traffic

[Service type] bandwidth throttle – XX KB/s
After selecting a domain from the drop-down list box, adjust these controls to set bandwidth limitations for the selected domain. A setting of "0" means no bandwidth limit is applied to that particular service type. Setting a slider to any number other than "0" will limit the maximum bandwidth to that number of Kilobytes per second for the designated service.

Click this checkbox if you want to throttle bandwidth on a per-service basis rather than the default per-session basis. When throttling on a per-service basis, the service
' s designated amount of bandwidth will be divided equally among all active sessions of the given service type. Thus, the total amount of bandwidth used, for example, by multiple IMAP clients connecting at the same time could never exceed the designated amount regardless of how many clients were connected. If throttling on a per-
session
basis, then no single IMAP session could exceed the designated limit but the total of multiple simultaneous sessions could.

Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
588 MDaemon Messaging Server 17.0
Tarpitting makes it possible for you to deliberately slow down a connection once a specified number of
RCPT
commands have been received from a message's sender. This is to discourage spammers from trying to use your server to send unsolicited bulk email
("spam"). You can specify the number of
RCPT
commands allowed before tarpitting begins and the number of seconds to delay the connection each time a subsequent command is received from that host during the connection. The assumption behind this technique is that if takes spammers an inordinately long period of time to send each message then that will discourage them from trying to use your server to do so again in the future.
Activate tarpitting
Click this check box to activate MDaemon
' s tarpitting features.
SMTP EHLO/HELO delay (in seconds)
Use this option to delay the server response to
EHLO
/
HELO
SMTP commands.
Delaying the responses by even as little as ten seconds can potentially save a significant amount of processing time by reducing the amount of spam received.
Frequently spammers depend on rapid delivery of their messages and therefore do not wait long for a response to
EHLO
/
HELO
commands. With even a small delay, spam tools will sometimes give up and move on rather than wait for a response.
Connections on the MSA port (designated on the
88
screen under Server
Settings) are always exempt from this delay. The default setting for this option is
"0", meaning
EHLO
/
HELO
will not be delayed.
Authenticated IPs experience a single EHLO/HELO delay per day
Click this check box if you wish to limit the EHLO/HELO delay to once per day for authenticated connections from a given IP address. The first message from that IP address will be delayed, but any subsequent messages sent from the same IP address will not.
SMTP RCPT tarpit threshold
Specify the number of SMTP
RCPT
commands that you wish to allow for a given host during a mail session before MDaemon will begin tarpitting that host. For example, if this number was set to 10 and a sending host attempted to send a message to 20 addresses (i.e. 20
RCPT
commands), then MDaemon would allow the first 10 normally and then pause after each subsequent command for the number of seconds specified in the
SMTP RCPT tarpit delay
control below.
SMTP RCPT tarpit delay (in seconds)
Once the
SMTP RCPT tarpit threshold
is reached for a host, this is the number of seconds that MDaemon will pause after each subsequent
RCPT
command is received from that host during the mail session.
Scaling factor
This value is a multiplier by which the base tarpit delay will be increased over time.
When the tarpit threshold is reached and the tarpit delay is applied to a session, each delay will be multiplied by this value to determine to length of the next delay in the session. For example, if the tarpit delay is set to 10 and the scaling factor is set to 1.5 then the first delay will be 10 seconds, the second will be 15 seconds, the third 22.5, then 33.75, and so on (i.e. 10 x 1.5 = 15, 15 x 1.5 = 22.5, etc.). The default Scaling factor is 1, meaning that the delay will not be increased.

5.6.5.4 Greylisting
Greylisting is located under the Security dialog at: S ecuri ty » S ecuri ty S etti ng s »
O ther » Greyli s ti ng . Greylisting is a spam-fighting technique that exploits the fact that
SMTP servers retry delivery of any message that receives a temporary (i.e. "try again later") error code. Using this technique, when a message arrives from a non-white listed or otherwise previously unknown sender, its sender, recipient, and sending server
' s IP address will be logged and then the message will be refused by Greylisting during the SMTP session with a temporary error code. Furthermore, for a designated period of time (say, 15 minutes) any future delivery attempts will also be temporarily refused. Because "spammers" do not typically make further delivery attempts when a message is refused, greylisting can significantly help to reduce the amount of spam your users receive. But, even if the spammers should attempt to retry delivery at a later time, it is possible that by that time the spammers will have been identified and other spam-fighting options (such as
497
) will successfully block them.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
590 MDaemon Messaging Server 17.0
It
' s important to note, however, that this technique can deliberately delay "good" email along with the "bad". But, the legitimate messages should still be delivered sometime later after the greylisting period has expired. It is also important to note that you have no way of knowing how long the sending servers will wait before making further delivery attempts. It is possible that purposely refusing a message with a temporary error code could cause it to be delayed by as little as just a few minutes or by as much as an entire day.
There are several traditional problems and negative side-effects associated with greylisting, and the Greylisting screen contains a number of options designed to deal with them.
First, some sending domains use a pool of mail servers to send outbound mail. Since a different mail server could be used for each delivery attempt, each attempt would be treated as a new connection to the greylisting engine. This could multiply the length of time it would take to get past Greylisting because each of those attempts would be greylisted as if they were separate messages instead of retries of a previous message.
By utilizing an SPF lookup option, this problem can be solved for sending domains who publish their SPF data. Furthermore, there is an option to ignore the IP of the sending mail server completely. Using this option lowers the efficiency of greylisting, but it does completely solve the server pool problem.
Second, greylisting traditionally entails a large database since each incoming connection must be tracked. MDaemon minimizes the need to track connections by placing the Greylisting feature nearly last in the SMTP processing sequence. This allows all of MDaemon
' s other options to refuse a message prior to reaching the greylisting stage. As a result, the size of the greylisting data file is greatly reduced, and since it is memory resident there is little practical performance impact.
Finally, several options are available to minimize the impact of greylisting on "good" messages. First, messages sent to mailing lists can be excluded. Next, Greylisting has its own white list file on which you can designate IP addresses, senders, and recipients that you wish to be exempt from greylisting. Finally, Greylisting contains an option for using each account
' s private address book files as a white list database. So, mail to a user from someone in that user
' s address book can be excluded from greylisting.

Defer initial delivery attempt with 451 for this many minutes
Designate the number of minutes for which a delivery attempt will be greylisted after the initial attempt. During that period of time, any subsequent delivery attempts by the same server/sender/recipient combination (i.e. "greylisting triplet") will be refused with another temporary error code. After the greylist period has elapsed, no further greylisting delays will be implemented on that triplet unless its Greylisting database record expires.
Expire unused greylisting database records after this many days
After the initial greylisting period has elapsed for a given greylisting triplet, no further messages matching that triplet will be delayed by Greylisting. However, if no message matching that triplet is received for the number of days designated in this option, its Greylisting database record will expire. A subsequent attempt by that triplet will cause a new Greylisting record to be created it will have to go through the initial greylisting period again.
Advanced
Click this button to open the Greylisting database, which you can use to review or edit your greylisting triplets.
SMTP response (leave blank for default)
If you provide a custom string of text in this space then MDaemon will return the
SMTP response, "451 <your custom text>" rather than the default "451
Greylisting enabled, try again in X minutes.
" This is useful, for example, if you wish to provide a string that contains a URL to a description of greylisting.

When using this option, if an incoming message matches a triplet

Creating an SMTP Site Policy Statement
Use this dialog to specify a Site Policy statement for your server. The text is stored in the
policy.dat
file located in MDaemon
' s
\app\
subfolder and is transmitted to sending servers at the beginning of every SMTP mail session. An example of a common site policy is, "
This server does not relay
" or "
Unauthorized use prohibited
." You do not need to prepend each line with "
220
" or "
220-
".
MDaemon handles each line accordingly, either with or without these prepended codes.
A site usage policy with a statement regarding relaying of mail would look like this during the SMTP transaction:
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Security Menu 595
220-Alt-N Technologies ESMTP MDaemon
220-This site does relay unauthorized email.
220-If you are not an authorized user of our server
220-then you must not relay mail through this site.
220
HELO example.com...
The
POLICY.DAT
file must be comprised of printable ASCII text only and have no more than 512 characters per line; however it is highly recommended that you use no more than 75 characters per line. The maximum size of this file is 5000 bytes.
MDaemon will not display files larger than 5000 bytes.

Mail Folder) will be automatically filled in while typing the first and last name and choosing the Mailbox domain. You can, however, change any of those default values. The first and last name field cannot contain " ! " or " | ".
Mailbox domain
Use this drop-down list box to specify the domain to which this account will belong and that will be used in its email address. MDaemon's
152
will appear in the drop-down list by default.
Mailbox name
This is the portion of the account's email address that sets it apart from other accounts on the domain. The complete email address (i.e. [Mailbox name]@[Mailbox
domain]) is used as the unique identifier for the account and as its login for POP3,
IMAP, WorldClient, and so on. Email addresses cannot contain spaces or “ ! ” or “|” characters. Do not use "@" in this option. For example, use "frank.thomas" not
"frank.thomas@".
New password (twice)
If you wish to change the account's password, type a new one here, once in each box. This is the password that the account will use when connecting to MDaemon to send or receive email via POP3 or IMAP, when authenticating during the SMTP process, or when using WorldClient, Remote Administration, or Outlook Connector.
Both of these boxes will be highlighted in red if the passwords do not match or they violate the
724
. Otherwise they will be green.
If you are using
Active Directory Authentication
733
for this account then you must enter two backslashes followed by the Windows domain to which the user belongs, rather than entering a password (for example, \\ALTN rather than 123Password).
Below the password fields there is a short statement to indicate whether AD authentication is enabled or disable for the account.
The account should have a password even if you do not wish to allow POP3/IMAP access to the mail account. In addition to mail session verification, the email address and Mailbox
password values are used to allow remote account configuration and remote file retrieval. If you wish to prevent
POP/IMAP access, use the options located on the
605
screen. If you wish to prevent all access, then use the
Account is DISABLED or Account is FROZEN options above.

6.1.1.5 Autoresponder
Accounts Menu 611
Autoresponders are useful tools for causing incoming email messages to trigger certain events automatically, such as running a program, adding the sender to a mailing list, responding with an automatically generated message, and more. The most common use of autoresponders is to reply to incoming messages automatically with a user-defined message stating that the recipient is on vacation, is unavailable, will reply as soon as possible, or the like. MDaemon users with
607
to
258
or
286
can use the options provided to compose auto response messages for themselves and schedule the dates they will be in use. Finally, automated response messages are based on
712
(*.RSP files), which support a large number of macros. These macros can be used to cause much of the script's content to be generated dynamically, making autoresponders quite versatile.
Auto response events are always honored when the triggering message is from a remote source. However, for messages originating locally, autoresponders will only be triggered if you enable the Autoresponders are triggered by intra-domain mail option, located on the
A utores ponders » S etti ng s
711
screen.
You can also use an option on that screen to limit auto response messages to one response per sender per day.

Use this auto response script
This field is used to specify the path and filename of the response file (
*.RSP
) that will be processed and used to compose the message that will be returned to the message sender. Response scripts may contain macros that can be used to make response messages dynamic and automate much of their content. See,
712
for more information.
Do not send auto response if message is from one of these addresses
Here you can list addresses that you wish to be excluded from responses initiated by this autoresponder.
Occasionally auto response messages may be sent to an address that returns an auto response of its own. This can create a "ping-pong" effect causing messages to be continually passed back and forth between the two servers. If you encounter one of those addresses, enter it here to prevent that from happening. There is also an option located on the
A utores ponders » S etti ng s
711
screen, which can be used to limit auto response messages to one response per sender per day.

Accounts Menu 613
Run a Program
Run this program
Use this field to specify the path and filename to a program that you wish to run when new mail arrives for this account. Care must be taken to ensure that this program terminates properly and can run unattended. Optional command line parameters can be entered immediately following the executable path if desired.
Pass message to process
Select this option and the process specified in the
Run this Program
field will be passed the name of the triggering message as the first available command line parameter. When the autoresponder is set for an account that is forwarding mail to another location and
not
retaining a local copy in its own mailbox (see
) then this function will be disabled.
614
By default, MDaemon will place the name of the message file as the last parameter on the command line. You can override this behavior by using the $MESSAGE$ macro. Use this macro in place of where the message file name should be placed. This allows more flexibility in the use of this feature since a complex command line such as this will be possible: logmail /e /j / message=$MESSAGE$ /q
.
Mailing Lists
Add sender to this mailing list
If a mailing list is entered in this field then the sender of the incoming message will be automatically added as a member of that mailing list. This is a handy feature for building lists automatically.
Remove sender from this mailing list
If a mailing list is entered in this field then the sender of the incoming message will be automatically removed from the specified mailing list.

Forwarding addresses (separate each address with a comma)
Use this field to designate any email addresses to which you wish to forward copies of this account's incoming messages as they arrive. A copy of each new message arriving at the server will be automatically generated and forwarded to the addresses specified in this field, provided the
Enable mail forwarding
option above is checked. When forwarding to multiple addresses, separate each one with a comma.
Retain a local copy of forwarded mail
By default, a copy of each forwarded message is delivered normally to the local user's mailbox. If you uncheck this box then no local copy will be retained.
Advanced Forwarding Settings
Forward the message to this domain
If you wish to route the forwarded messages through a particular domain
' s MX servers, then specify that domain here. If you wish to route the messages to a specific host, then enclose the value in brackets (e.g. [
host1.example.com])
.
Use this address in SMTP envelope
If an address is specified here, it will be used in the "MAIL From" statement sent during the SMTP session with the accepting host, instead of using the actual sender of the message. If you require an empty SMTP "MAIL From" statement (i.e. "MAIL
FROM <>
") then enter "[trash]" into this option.
Use this TCP port
MDaemon will send the forwarded messages using the TCP port specified here. The default SMTP port is 25.

Do not extract attachments from messages
If this option is selected, attachments will not be extracted from the account's messages. Messages with attachments will be handled normally, leaving the attachments intact.
Extract attachments and put them in account's Documents folder
If set, this option causes MDaemon to automatically extract any Base64 MIME embedded file attachments found within incoming mail messages for this account.
Extracted files are removed from the incoming message, decoded, and placed in the account
' s Documents folder. A note is then placed within the body of the message, stating the names of the files that were extracted. This option does not provide a link to the stored attachments, but users can use
258

Use Attachment Linking feature
Select this option if you wish to use the Attachment Linking feature for inbound or outbound messages with attachments.
If this option is selected but the Attachment Linking feature is disabled on the
298
dialog, then attachments will not be extracted.
Extract attachments from inbound messages
When this option is enabled, attachments will be extracted from the account's incoming messages and stored in the location designated on the
298
dialog. URL links are then placed within the body of the message, which the user can then click to download the files. For security these URL links do not contain direct file paths. Instead they contain a unique identifier (GUID) that the server uses to map the file to the actual path. This GUID map is stored in the AttachmentLinking.dat file. This option is enabled by default.
Extract attachments from outbound messages
Check this box if you wish to use the Attachment Linking feature to extract attachments from the account's outbound messages. When the account sends an email, Attachment Linking will extract the file, store it, and replace it with a
URL to download the file.

6.1.1.10 IMAP Filters
Accounts Menu 623
With MDaemon, IMAP and
258
users can have their mail routed automatically to specific folders on the server by using filters. Similar to the
431
,
MDaemon will examine the headers of each of the account's incoming messages and then compare them to the account's filters. When a message for the account matches one of its filters, MDaemon will move it to the folder specified in that filter. This method is much more efficient (for both the client and server) than attempting to filter the messages at the client, and since some mail clients do not even support local message rules or filtering, mail filters provide this option to them.
Administrators can create filters via the IMAP Filters screen of the Account Editor, or by using
286
. However, you can also grant your users permission to create and manage filters for themselves from within WorldClient or Remote
Administration. These permissions are set on the
607
screen.
Existing IMAP filter rules
This box displays the list of all filters that have been created for the user's account.
Filters are processed in the order in which they are listed until a match is found.
Therefore, as soon as a message matches one of the filters it will be moved to the folder specified in that filter and then filter processing for that message will cease.
Use the Up and Down buttons to move filters to different positions in the list.

MDaemon will scan that header in all of the account
' s incoming messages for the text contained in the "
this value
" box below. Then, based upon the type of comparison being made, it will determine which messages should be moved to the filter
' s specified folder.
Comparison-type
Use this drop-down list to choose the type of comparison that will be made to the message
' s header or size indicated in the filter. MDaemon will scan the specified header for the text contained in the "

—does the message size or header
' s complete text match exactly, not match exactly, contain the text, not contain it at all, start with it, and so on.

Enter the text that you want MDaemon to search for when scanning the message header that you have specified for the filter. When the filter is set to check the message
' s size, set this value to the desired number of KB.
...then move message to this folder
After specifying the various parameters for the filter, click the folder that you want messages matching it to be moved to and then click the Add filter button to create the filter. This list also contains the following three special entries: "!!Delete
Message!!," "!!Redirect Message!!," and "!!Forward Message!!."
!! Delete Message !! – Choose your filter values, click this option in the folder list, and then click Add filter to create a filter that will cause a message to be deleted when it matches the filter's conditions.
!! Redirect Message !! – Choose your filter values, click this option in the folder list, click Add filter, and then enter an Email address. This will create a filter that will cause a message that meets the filter's conditions to be redirected to the designated email address. No changes to the message headers or body will be made. The only thing changed is the SMTP envelope

recipient.
!! Forward Message !! – Choose your filter values, click this option in the folder list, click Add filter, and then enter an Email address. This will create a filter that will cause a message that meets the filter's conditions to be forwarded to the designated email address. A new message will be created and sent, with the Subject header and body content taken from the original message.

Example,
The parent folder grants certain permissions to User_A and User_B. The child folder grants permissions to User_B and User_C. This option will add User_A permissions to the child folder, replace the child folder's User_B permissions with those from the parent folder, and do nothing to the User_C permissions. Therefore the child folder will then have User_A, User_B, and User_C permissions.

Access rights are controlled through MDaemon's support for
Access Control Lists (ACL). ACL is an extension to the Internet
Message Access Protocol (IMAP4), which makes it possible for you to create an access list for each of your IMAP message folders, thus granting folder access rights to other users who also have accounts on your mail server. If your email client doesn't support ACL you can still set the permissions via the controls on this dialog.
ACL is fully discussed in RFC 2086, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2086.txt

6.1.1.15 BlackBerry Internet Service
If a BlackBerry smartphone is using the BlackBerry Internet Service (BIS) to collect this account's email, you can use this screen to specify the IMAP folders whose new messages you wish to push to the smartphone's Inbox. Ordinarily the BlackBerry
Internet Service only collects messages from the user's Inbox folder, not from any other folders associated with the user's account. Therefore if he or she is using

This feature does not, however, deliver messages that were already contained in any of the folders—it only delivers new messages. If the account has no IMAP filters then this screen will be blank.
The folders themselves are not pushed to the BlackBerry device, only the new messages that are placed in them. All messages will be delivered to the device's Inbox, not to any specific folders on the device.

Archive [XML | WBXML] requests and responses
Use the Archive XML... and WBXML options if you wish to save this data, which can sometimes be useful for debugging purposes. The global options are disabled by default.
Validate/correct PIM mrk file integrity
This option runs a validation and correction process on the client's PIM data to look for known issues that could prevent it from syncing correctly, such as duplicate iCal
UIDs or empty required fields. The global option is disabled by default.
Options
Create Tasks/Reminders for flagged mail items
This option makes it possible for MDaemon to remind the user about flagged items, by creating a task item for each flagged email. This is disabled by default.
Allow search operations on...
Public Folders
Allows the client to search the
251
to which it has access. This is allowed by default.
Shared Folders
Allows the client to search the
629
to which it has access. This is allowed by default.
Send server based read receipts when requested.
Enable this option if you want the server to support read confirmation requests and issue a read receipt when a message is flagged as read by a client. This is disabled by default.
Request read receipts for all mail sent
Enable this option if you want the server to request read confirmation for all mail sent by a client. This is disabled by default.
Enforce protocol restrictions
Enable this option if you wish to deny connections from any client that attempts to use a protocol other than the the Allowed Protocol Versions specified for the client.
By default this option is disabled, which means that protocol restrictions do not prevent a client from using a different protocol; they simply tell the client which protocols to use. If a client attempts to use a restricted protocol anyway, MDaemon will still allow the connection.
Allow clients to connect that are managed by other servers
By default, when the ActiveSync server sends provisioning data/policy specifics to a client and it reports that it is also managed by another ActiveSync server, the client will still be allowed to connect to MDaemon. In this circumstance, however, there is no way to ensure that your policy specifics will be applied where they conflict with the other ActiveSync server's policy. Generally clients default to using the most
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
644 MDaemon Messaging Server 17.0
restrictive option where policies conflict. Disable this option if you do not wish to allows those clients to connect.
Respond with logon alias as 'PrimarySmtpAddress' in Get/UserInformation
This allows the service to return an alias/secondary address as the primary address in response to a Settings/Get/UserInformation request. This works around an issue caused by a post iOS9.x update that resulted in clients not being able to send mail using an alias. Using this option results in a non-specification compliant response to
Settings/Get/UserInformation.
New clients must be authorized by administrator prior to synchronizing
Enable this option if you wish to require that new clients must first be authorized by an administrator before they can begin synchronizing with an account. The
358
list indicates any clients awaiting authorization, and the administrator can authorize them from the same screen. This option is available on the Global and
Account client settings screens. The global option is Off by default and the account option is set to "Inherit."
Maximum number of clients per user
If you wish to limit the number of ActiveSync clients or devices that can be associated with an MDaemon account, specify the desired number in this option.
The global option is set to "unlimited" by default. This option is available on the
Global, Domain, and Account client settings screens, not the individual Clients screens.
Day of month to reset bandwidth statistics
Use this option if you wish to reset the bandwidth usage statistics for ActiveSync devices on a specific day of each month. The reset event takes place as part of the normal nightly maintenance process and is logged to the System log like other maintenance routines. The global option is set to "0 (Never)" by default, meaning the usage stats will never be reset. Set the child options to a different day if, for example, you want the reset day to coincide with a user or client's wireless carrier billing reset date.
Folder Options
Allow Public Folder traversal (exposes secured folder names)
By default, in order for a client to sync/access a public subfolder, the account must have
253
for both the subfolder (i.e. child folder) and all parent
251
above it. If the account does not have permission to see the parent folders then it cannot see the child folder either, even if the account has permission to do so. Enable this option if you wish to allow the client to access these child folders. Note: enabling this option must necessarily reveal the names of the parent folders to the client, which could be deemed a security risk. This option is disabled by default.
Exclude user's [whitelist/blacklist] folder
By default the user's whitelist and blacklist contact folders are not synced with devices. They are generally only used by MDaemon to help with automatic spam prevention. For that reason they do not need to be displayed on devices as contacts.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 645
Exclude all non-default mail folders
By default all user-created and default mail folders can be synced with the device.
Enable this option if you wish to allow only the default mail folders to be synced, i.e.
the Inbox, Sent Items, Deleted Items, Drafts, and so on. No user-created folders will be included. This option is disabled by default.
Exclude all non-default PIM folders
By default all of the user's PIM folders (i.e. contacts, calendar, notes, tasks, etc.) will be synced with the device. Enable this option if you wish to allow only the default PIM folders to be synced. For example, if this option is enabled and a user has multiple calendar folders, only the default calendar will be synced. This option is disabled by default.
Include Public Folder hierarchy
Check this box if you want the
251
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Include shared folders
Check this box if you want the
120
to which a user has access to be included in the user's folder list on ActiveSync devices. This is enabled by default.
Virtually merge public contacts into default contacts
Enable this option if you wish to merge the public contacts with the user's default contacts on the device. This is only a virtual merge, that is they are not actually copied to the user's contacts folder. This can be useful on clients that do not support Global Address List (GAL) searches. This is disabled by default.
Maximum number of Public Folders allowed
Use this option if you wish to limit the number of Public Folders allowed on the device. When a limit is set, the server iterates through the list of folders until the limit is reached, and then no more are sent to the device. There is no way to ensure the order in which folders will be processed. By default there is no global limit set.

Removing an ActiveSync Device
To remove an ActiveSync device, select the device and click Remove. This will remove the device from the list and delete all synchronization information related to it in
MDaemon. Therefore if in the future the account uses ActiveSync to synchronize the same device, MDaemon will treat the device as if it had never before been used on the server; all device data will have to be re-synchronized with MDaemon.
Full Wiping an ActiveSync Client
To do a Full Wipe on an ActiveSync client or device, select the client from the list and click Wipe Client and then Wipe Client (Factory reset). The next time the client connects, MDaemon will tell it to erase all data, or restore itself to its factory default state. Depending on the client, this may remove everything on it, including downloaded apps. Further, as long as the client's ActiveSync entry exists in MDaemon, it will be wiped again if it ever connects again to MDaemon in the future. If you no longer wish to wipe the client when it connects (for example, if a lost device is recovered and you wish to use it again with the account) then you must first use the Remove option above to remove the client from MDaemon.
Account Wiping an ActiveSync Client
To wipe the account's mail and PIM data from the client or device, click Wipe Client and then Account Wipe (Account's Mail and PIM data only). The Account Wipe option is similar to the Full Wipe option explained above, but instead of wiping all data, it will wipe only the account's data, such as its emails, calendar entries, contacts, and the like. The rest, such as apps, photos or music is left alone.

Remove contacts which are missing name or phone data
Click this button if you wish to remove every contact that contains only an email address from the account's default Contacts folder. If a contact doesn't have at least a name or phone data it will be removed. The option is primarily to help those who were using MDaemon's automatic white listing option prior to version 11 purge contacts that were added purely as a function of the white list feature. In previous versions of MDaemon the addresses were added to the main contacts instead of to a dedicated white list folder. This could result in the account having many entries in the contacts folder that the user would rather not have there.
Consider this option carefully before using it, because contacts containing only an email address could still be legitimate.

Subaddressing
Subaddressing is a system for including a folder name in the mailbox portion of an account's email address. Using this system, messages addressed to the mailbox
+folder name combination will be routed automatically to the account's folder included in the address (assuming that folder actually exists), without the need to create specific filtering rules to make that happen.
For example, if
[email protected]
has an IMAP mail folder called "
stuff
," then mail arriving addressed to "
[email protected]
" would be routed automatically to that folder. Subfolders can be designated by including the folder and subfolder names separated by an additional "+" character, and underscores are used to replace spaces in folder names. So, using the example above, if Bill's "
stuff
" folder had a subfolder called "
my older stuff
," then messages addressed to
"
[email protected]
" would be routed automatically to Bill's "
\stuff\my older stuff\
" mail folder.
Since subaddressing requires the use of the "
+
" character, mailboxes that contain "
+
" cannot be subaddressed. So, in the example above, if the actual address were "
bill
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 661
[email protected]
" instead of "
[email protected]
" then it could not be subaddressed. Further, you cannot use an address alias in a subaddress. You can, however, create an alias that refers to an entire subaddressed form. So, even though "
[email protected]
" is not permitted, using "
[email protected]
" to point to "
[email protected]
" would be fine.
To prevent exploits or abuse, the IMAP folder included in the subaddress must be valid. If a subaddressed message arrives for an account that does not have a folder matching the name of the folder defined in the subaddress, then the subaddress will be treated as an unknown email address and handled accordingly, based on your other MDaemon settings. For example, if
[email protected]
does not have a folder named "
stuff
" and yet a message arrives for "
bill.farmer
[email protected]
" then that message will be treated as if were addressed to an unknown user, and it will most likely be rejected.
By default, each account has the subaddressing feature disabled. You can, however, disable this feature globally via the Disable subaddressing feature for all accounts option located on the
422
screen of the Preferences dialog. If Subaddressing is disabled via that option, it will not be permitted for any account, regardless of the individual account settings.

The Group Manager (A ccounts » Groups & T emplates ... » Group M anag er) is used to create account Groups and manage which accounts belong to them. Groups have a number of different uses and functions. For example, using the
663 screen you can assign an account
666
to a Group, allowing you to control a variety of account settings for group members. You can also control whether or not group members have access to
259
and instant messaging. Further, the Content Filter supports groups, allowing you to create
433
based on whether or not a message sender or recipient is a member of a specific Group. Finally, for
118
you can assign
253 rights to specific Groups, meaning all members of that Group will share those access rights.
You can add accounts to a Group by selecting the Group from the list below and then clicking the "Add or remove accounts..." button. You can also add users to Groups from each user's
604
screen.

. To open Group Properties from the Group Manager, double-click the group you wish to edit, or click the name of the group in the left pane. On this screen you can assign an
666
to a group, allowing you to control a variety of account settings for group members. You can also link the group to an Active Directory group, control whether or not group members have access to
259
and instant messaging, and set a priority level for the group. To control group membership, use the Group Manager and
604
screen on the Account Editor.
Group Properties
Describe this group
Enter a description of the group here, for your own reference. This information is typically entered when you create the group but can be edited from this screen at any time.
Account template (optional)
If you have created an
666
that you would like to use to control some of the account settings for group members, use this drop-down list to select the desired template. When an account template is linked to a group, any category of account settings designated on
668
will be used for all accounts belonging to the group. The template will be used to control those settings rather than using the individual account settings on the Account Editor. If an account is removed from a group that was controlling its account settings, the settings will revert to the values designated by the
667
.
If an account belongs to multiple groups linked to different templates, then all of the templates will be used wherever there are no conflicts in the designated
668
. If multiple templates are set to control the same properties, then the first template listed is the one that will be used.
Active Directory group (optional - requires AD monitoring)
Use this option if you wish to link the group to a specific Active Directory group.
Members of the Active Directory group will added to the account group automatically. But for this to work you must be using the
695
feature.
You can map any Active Directory attribute you want to use as a trigger for adding accounts to Groups, although the "memberOf" attribute will most likely be the one to use. You can configure this by editing ActiveDS.dat in notepad. This feature is disabled by default. To enable it, edit ActiveDS.dat and specify which attribute to use for your group trigger, or uncomment the "Groups=%memberOf%" line in
ActiveDS.dat
to use it.
Disable WorldClient Instant Messenger
Click this box if you wish to disable WCIM support for all members of the group.
Disable Instant Messaging
Click this box if you wish to allow support for WCIM but not its Instant Messaging feature.

Accounts Menu 665
Priority (1-1000 - lower values have priority over higher ones)
Use this option to set a priority level (1-1000) for your groups, which allows accounts to be members of multiple groups and avoid possible conflicts between group settings. For example, when an account is a member of multiple groups that each have a linked account template controlling the same settings, the settings for the group with the first Priority will be used. In other words, a group with a Priority value of "1" will be over a group with a value of "10". When there is no conflict the settings for each group are collectively applied. In the case of a tie the first group found wins. When an account is removed from a group linked an account template, the account settings previously controlled by the account template will change to the account settings designated by the next Priority group. If there isn't another group controlling those settings, then they will revert to settings designated by the
667
.
Do Not Disturb
Use the Do Not Disturb feature to schedule a time frame during which an account may not send mail or be accessed by its users. Access during a Do Not Disturb period is not allowed and returns an appropriate error response to IMAP, POP, SMTP, ActiveSync, and WorldClient access requests. MDaemon will still accept incoming mail for accounts in this state, but those accounts may not send mail or be accessed by mail clients.
To apply Do Not Disturb to one or more accounts:
1. Click Enable Do Not Disturb.
2. Click Define Do Not Disturb Schedule.
3. Set the start/end dates, the start/end times, and the days of the week to use it.
4. Click Ok.
5. Use the
662
to assign any accounts to this group that you wish to use it.

6.2.2 Template Manager
With the Template Manager (A ccounts » Groups & T emplates ... » T emplate M anag er) you can create and manage Account Templates, which are named sets of account settings that can be assigned to specific
662
. Any account belonging to one or more of those groups will have the designated account settings locked, being controlled only by the assigned templates rather than by the Account Editor. The categories of account settings that a template will control are designated on each template's
668
screen, which is reached by double-clicking the template's name in the list below, or by clicking the template in the left pane.

Template List
The list on the bottom of the Template Manager contains all your templates. Click a template and then use the buttons at the top of the screen to delete or rename it.
Double-click a template to open its
668
screen from which you can designate the categories of account settings that it will control. You can jump directly to any template and its account settings using the controls in the left pane. The New
Accounts template is a special template that always appears first in the list.
New Accounts Template
The New Accounts template is a special template that is applied to all new accounts when they are created. Rather than locking and controlling certain account settings like other templates, New Accounts is used simply to designate the initial settings for new accounts. Those initial settings can then be changed normally by using the
Account Editor to edit individual accounts. Some template settings, such as the options located on the
688
screen, are not available to the New
Accounts template.

6.2.2.1 Template Properties
To access a template's properties screen, open the
666
and click the template's name in the left pane. Use each template's properties screen to designate the categories of account settings that the template will control. Any account belonging to a
662
that utilizes an account template will have the corresponding
Account Editor screens locked, since those settings will be controlled by the template.
If an account belongs to multiple groups linked to different templates, then all of the templates will be used wherever there are no conflicts in the designated template properties. If multiple templates are set to control the same properties, then the first template listed is the one that will be used.
Template Control
All possible account settings
Click this checkbox if you would like this template to control all available account settings for
662
using the template. All of the template screens will be used for each group member's account settings instead of the corresponding screens of the same name on the Account Editor. Clear this check box if you wish to use the
Account Settings options below to pick specific account settings to control.
Account Settings
This section lists all of the categories of account settings that the template may control for Groups utilizing the template. Each option corresponds to the template screen of the same name. When an option is selected, the settings on that template screen will be used instead of the settings on the corresponding Account Editor

screen for associated group members.
New Account Settings
These options are only available on the
667
. They use a variety of
670
to automatically generate the mail storage folder and the mailbox portion of the email address for new accounts.
Mailbox
Use this field to control the default
601
portion of the email address that will be generated for new accounts. See
670
below for a list of the Macros that can be used in this template string.
"
$USERFIRSTNAMELC$.$USERLASTNAMELC$
" is the default template for this option. Therefore creating an account for "Michael Mason" under the example.com
domain would result in his address being set to "
[email protected]
".
Mail folder
Use this field to control the default
604
that will be used for new accounts. Each account's Mail folder is where its email messages will be stored on the server. For example, "...\$DOMAIN$\$MAILBOX$\" would create the path, "...
\example.com\michael.mason\
" for the user, "[email protected]".
MDaemon supports a basic system for folder hashing. Under
NTFS, keeping many folders under the same root can sometimes cause performance problems. If you have large numbers of users and wish to subdivide the user folders beyond the default $DOMAIN$\$MAILBOX$\ setup, you can use the macro $MAILBOXFIRSTCHARSn$ to do so. Using this macro,
"n" is a number between 1 and 10 and will expand to the first
"n" characters of the mailbox name. Changing your default Mail
folder path to something like the following will achieve a decent folder hashing system:
C:\MailboxRoot
\$MAILBOXFIRSTCHARS4$\$MAILBOXFIRSTCHARS2$\$MAILBOX$
\
.
Account must change mailbox password before it can connect
This option controls whether or not the new account must change its Mailbox
password before it can access POP, IMAP, SMTP, WorldClient, or Remote
Administration. The user can connect to WorldClient or Remote Administration but will be required to change his or her password before proceeding. Note, however, that in order for users to be able to change their passwords via WorldClient or
Remote Administration they must first be granted the "...edit password" web access permission on the
673
screen. After the password is changed this option will be deactivated on the account's
601
screen.
Because changing the password may not be easy or possible for some users, you should exercise caution before activating

screen. When a template is set to

that utilizes the template.
Autoresponders are useful tools for causing incoming email messages to trigger certain events automatically, such as running a program, adding the sender to a mailing list, responding with an automatically generated message, and more. The most common use of autoresponders is to reply to incoming messages automatically with a user-defined message stating that the recipient is on vacation, is unavailable, will reply as soon as possible, or the like. MDaemon users with
607
to
258
or
286
can use the options provided to compose auto response messages for themselves and schedule the dates they will be in use. Finally, automated response messages are based on
712
(*.RSP files), which support a large number of macros. These macros can be used to cause much of the script's content to be generated dynamically, making autoresponders quite versatile.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.

Auto response events are always honored when the triggering message is from a remote source. However, for messages originating locally, autoresponders will only be triggered if you enable the Autoresponders are triggered by intra-domain mail option, located on the

You can also use an option on that screen to limit auto response messages to one response per sender per day.

Use this auto response script
This field is used to specify the path and filename of the response file (
*.RSP
) that will be processed and used to compose the message that will be returned to the message sender. Response scripts may contain macros that can be used to make response messages dynamic and automate much of their content. See,
712
for more information.
Do not send auto response if message is from one of these addresses
Here you can list addresses that you wish to be excluded from responses initiated by this autoresponder.
Occasionally auto response messages may be sent to an address that returns an auto response of its own. This can create a "ping-pong" effect causing messages to be continually passed back and forth between the two servers. If you encounter one of those addresses, enter it here to prevent that from happening. There is also an option located on the

want the Autoresponder to be active continually.
Run a Program
Run this program
Use this field to specify the path and filename to a program that you wish to run when new mail arrives for a group member controlled by this template. Care must be taken to ensure that this program terminates properly and can run unattended.
Optional command line parameters can be entered immediately following the executable path if desired.
Pass message to process
Select this option and the process specified in the
Run this Program
field will be passed the name of the triggering message as the first available command line parameter. When the autoresponder is set for an account that is forwarding mail to another location and
not
retaining a local copy in its own mailbox (see
) then this function will be disabled.
614
By default, MDaemon will place the name of the message file as the last parameter on the command line. You can override this behavior by using the $MESSAGE$ macro. Use this macro in place of where the message file name should be placed. This allows more flexibility in the use of this feature since a complex command line such as this will be possible: logmail /e /j / message=$MESSAGE$ /q
.
Mailing Lists
Add sender to this mailing list
If a mailing list is entered in this field then the sender of the incoming message will be automatically added as a member of that mailing list. This is a handy feature for building lists automatically.

option above is checked. When forwarding to multiple addresses, separate each one with a comma.
Retain a local copy of forwarded mail
By default, a copy of each forwarded message is delivered normally to the local user's mailbox. If you uncheck this box then no local copy will be retained.
Advanced Forwarding Settings
Forward the message to this domain
If you wish to route the forwarded messages through a particular domain
' s MX servers, then specify that domain here. If you wish to route the messages to a specific host, then enclose the value in brackets (e.g. [
host1.example.com])
.
Use this address in SMTP envelope
If an address is specified here, it will be used in the "MAIL From" statement sent during the SMTP session with the accepting host, instead of using the actual sender of the message. If you require an empty SMTP "MAIL From" statement (i.e. "MAIL
FROM <>
") then enter "[trash]" into this option.
Use this TCP port
MDaemon will send the forwarded messages using the TCP port specified here. The default SMTP port is 25.

6.3 Account Settings
6.3.1 Active Directory
Using the Active Directory options located at A ccounts » A ccount S etti ng s » A cti v e
Di rectory
, MDaemon can be configured to monitor Active Directory and automatically create, edit, delete and disable MDaemon accounts when their associated accounts are altered in Active Directory. Further, it can also be set to keep all public contact records updated with the most recent information stored in Active Directory. Common fields like an account's postal address, phone numbers, business contact information, and so on can be populated into the public contact records and updated any time they are changed in Active Directory.
Creating Accounts
When set to monitor Active Directory, MDaemon will query for changes at a designated
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 693
interval and then create a new MDaemon user account whenever it finds that a new
Active Directory account has been added. This new MDaemon user account will be created using the full name, logon, mailbox, description, and enabled/disabled state found within Active Directory.
By default, new MDaemon accounts created as a result of Active Directory monitoring will be added to MDaemon
' s Default Domain. Alternatively, you can choose to have those accounts added to the domain found within the account
' s
"
UserPrincipalName
" Active Directory attribute. When using this option, if an account requires a domain that doesn't yet exist within MDaemon, a new
152
will be created automatically.
Deleting Accounts
MDaemon can be configured to take one of the following actions when an account is deleted from Active Directory: do nothing, delete the associated MDaemon account, disable the associated MDaemon account, or freeze the associated MDaemon account
(i.e. the account can still receive mail but the user can
' t collect it or access it).
Updating Accounts
When MDaemon detects changes to Active Directory accounts, it will automatically update the associated properties in the matching MDaemon account.
Synchronizing MDaemon with Active Directory
A "
Perform full AD scan now
" option is available to cause MDaemon to query the Active
Directory database and then create or modify MDaemon user accounts as necessary.
When an Active Directory account is found that matches an already existing MDaemon account, the MDaemon account will be linked to it. Then, any future changes made to the Active Directory accounts will be propagated to the MDaemon accounts automatically.
Active Directory Authentication
Accounts created by MDaemon
' s Active Directory feature will be setup for Active
Directory (AD) Authentication by default. With AD Authentication, MDaemon has no need to store the account
' s password within its own user database. Instead, the account holder will use his or her Windows login/password credentials and MDaemon will pass those to Windows for authentication of the associated account.
To use AD Authentication with Active Directory, a Windows domain name must be present in the space provided on the
695
. This is the Windows domain that
MDaemon will use when attempting to authenticate accounts. In most cases, MDaemon will detect this Windows domain name automatically and fill it in for you. However, you can use an alternate domain in this option if you choose, or you can use "
NT_ANY
" if you wish to allow authentication across all of your Windows domains inste of limiting it to a specific one. If you leave this option blank then MDaemon will not use AD
Authentication when new accounts are created. Instead it will generate a random password, which you will have to edit manually before users will be able to access their mail accounts.
Persistent Monitoring
Active Directory monitoring will continue to work even when MDaemon is shut down. All
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
694 MDaemon Messaging Server 17.0
Active Directory changes will be tracked and then MDaemon will process them once it restarts.
Active Directory File Security
It is worth noting that MDaemon
' s Active Directory features do not alter the Active
Directory schema files in any way — all monitoring is one-way from Active Directory to
MDaemon. MDaemon will not alter your directory.
Active Directory Template
Whenever MDaemon adds or makes changes to accounts due to Active Directory monitoring and scanning, it will use an Active Directory template ("
/app/
ActiveDS.dat
") to link certain Active Directory attribute names to MDaemon
' s account fields. For example, MDaemon links the Active Directory attribute " cn
" to
MDaemon
' s "
FullName
" field by default. These links, however, are not hard-coded.
You can easily edit this template with Notepad if desired and alter any of the default field mappings. For example, "
FullName=%givenName% %sn%
" could be used as a replacement for the default setting: "FullName=%cn%". See
ActiveDS.dat
for more information.
Updating the Public Address Books
Active Directory monitoring can be used to periodically query Active Directory and keep all public contact records in MDaemon updated with the most recent information.
Common fields like an account's postal address, phone numbers, business contact information, and so on will be populated into their public contact record, and this data will be updated any time it is changed in Active Directory. To enable this feature, use the "Monitor Active Directory and update public address book(s)" option located at:
A cti v e Di rectory » M oni tori ng
695
.
Numerous contact record fields can be monitored using this feature. For a complete list of which public contact record fields can be mapped to Active Directory attributes, see the ActiveDS.dat file. This file has several new mapping templates which allow you to specify one or more Active Directory attributes from which to populate a particular contact record field (for example, %fullName% for the fullname field, %streetAddress% for the street address field, and so on).
MDaemon must match an account's email address to some attribute within Active
Directory in order to know which contact record to update. If it can't find such a match it does nothing. By default MDaemon will try to construct an email address using the data taken from the attribute mapped to the Mailbox template (see ActiveDS.dat) to which MDaemon will internally append the
152
name, just as it would when actually creating and deleting accounts based on Active Directory data.
However, you can uncomment the "abMappingEmail" template inside ActiveDS.dat and tie it to any Active Directory attribute you wish (like %mail%, for example). However, please note that the value of this attribute must contain an email address that will be recognized as a valid local user account.
This feature will create the contact records on the fly if they don't already exist and it will update contact records that do exist. Further, please note that it will overwrite any changes you make outside of Active Directory. Contact record fields that are not mapped are left unaltered. Therefore any existing data that is not subject to this
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 695
process will not be altered or lost. Finally, MDaemon accounts that are set to

' s associated Active Directory account is deleted.
...do nothing
Choose this option if you do not wish MDaemon to make any changes to an
MDaemon account when its associated account is deleted from Active Directory.
...delete them from MDaemon also
Choosing this option will cause the MDaemon account to be deleted when its associated account is deleted from Active Directory.
This will cause the associated MDaemon account to be completely removed. All of the account's messages, message folders, address books, calendars, and so on will be deleted.
...disable the MDaemon account
When this option is selected and an Active Directory account is deleted, its corresponding MDaemon account will be disabled. This means that the MDaemon account will still exist on the server, but it cannot send or receive email or be accessed by anyone.
...freeze the MDaemon account
When this option is selected MDaemon will still accept the account
' s incoming mail but effectively "lock" it so that it cannot be accessed. In other words, incoming mail addressed to that account will not be rejected or deleted by
MDaemon but the account holder will not be able to collect or access that mail as long is the account is frozen.

Freeze MDaemon accounts when they are disabled in Active Directory
By default, when you disable an account in Active Directory, MDaemon will also disable the associated account in MDaemon. This makes the account inaccessible and MDaemon will neither accept nor deliver messages for it. However, if you prefer to have the associated MDaemon account frozen instead of disabled, enable this option. MDaemon will still accept messages for frozen accounts, but users will not be able to access those accounts to collect or send their email.

6.3.1.3 LDAP
MDaemon supports Lightweight Directory Access Protocol (LDAP) functionality. Click
"Accounts » Account Settings » LDAP" to reach the LDAP screen used for configuring
MDaemon to keep your LDAP server up to date on all of its user accounts. MDaemon can maintain an accurate and continuously up to date LDAP database of users by communicating with your LDAP server each time an MDaemon account is added or removed. This makes it possible for users with mail clients that support LDAP to "share" a global address book that will contain entries for all of your MDaemon users as well as any other contacts that you include.
You can also use your LDAP server as the
717
rather than its local
USERLIST.DAT
system or an ODBC compliant database. You might want to use this method of maintaining your user information if you have multiple MDaemon servers at different locations but want them to share a single user database. Each MDaemon server would be configured to connect to the same LDAP server in order to share user information rather than storing it locally.

names, email addresses, and aliases by enabling this checkbox. Thus, you can still keep an LDAP server up to date for use as a global address book system for users of email clients that contain support for
LDAP address books.
This will maintain a database of your mailboxes, aliases, and mailing lists that your remote backup servers can query for remote verification of address information. See

' s distinguished name (DN). For all peer entries (those sharing a common immediate parent) the RDN must be unique, therefore we suggest using each user
' s email address as their RDN to avoid possible conflicts. Using the $EMAIL$ macro as the value of the attribute in this control (i.e.
mail=$EMAIL$
) will cause it to be replaced by the user
' s email address when their LDAP entry is created. The user

' s distinguished name (DN).
Object class (database)

Object class (address book)
Specify the object class to which each MDaemon user
' s LDAP address book entry must belong. Each entry will contain the objectclass=
attribute with this as its value.
Base entry DN (remote verification)
One common problem with domain gateways and backup servers is that they don
' t usually have a method for determining whether or not the recipient of an incoming message is valid. For instance, if a message comes to example.com
' s backup server for [email protected] then the backup server has no way of knowing whether or not there is actually a mailbox, alias, or mailing list at example.com for "user1". Thus the backup server has no choice but to accept all of the messages. MDaemon contains a method for verifying these addresses and solving this problem. By specifying a Base entry DN that will be used for all mailboxes, aliases, and mailing lists, your LDAP server can be kept up to date with all of this information. Then, your backup server can simply query your LDAP server each time a message arrives for your domain and verify whether or not the recipient
' s address is valid. If it isn
' t then the message will be rejected.
Server is protocol version 3
Click this checkbox if want MDaemon to use LDAP protocol version 3 with your server.
Chase referrals
Sometimes an LDAP server doesn't have a requested object but may have a crossreference to its location, to which it can refer the client. If you want MDaemon to chase (i.e. follow) these referrals, enable this option. This is disabled by default.
Cache LDAP lookup results
By default MDaemon caches LDAP lookup results. Disable this option if you do not wish to cache them.
Export full name with aliases
Non-aliases exported to an LDAP address book put the account's full name in the CN field. Aliases, however, have the account's actual (non-alias) email address placed there. Check this box if you want to put the account's full name (if known) there instead. This option is disabled by default.
Configure
Click this button to open the

6.3.2 Aliases
6.3.2.1 Aliases
Accounts Menu 703
The Aliases features makes it possible for you to create alternate mailbox names for your accounts or mailing lists, which are useful when you want multiple mailbox names to resolve to a single user account or list. Without aliases you'd have to create separate user accounts for each address and then forward messages or use complicated filter rules to associate them with other accounts.
For example, if [email protected] handled all billing inquiries to your domain, but you wanted to tell everyone to send them to [email protected], then you could create an Alias so that messages addressed to [email protected] would actually go to [email protected]
. Or, if you were hosting multiple domains and wanted all messages addressed to the Postmaster (regardless of the domain) to go to [email protected], then you could use a wildcard to associate the alias, Postmaster@*, with his address.

Fully qualified aliases (no wildcards) are allowed to be list members
Click this checkbox if you want to allow aliases to be members of MDaemon mailing lists. Only actual accounts can be list members if this control is not enabled. Note: aliases containing wildcards are not permitted to be list members even if this option is enabled.
Mail from 'Postmaster,' 'abuse,' 'webmaster' requires authentication
When this option is enabled, MDaemon will require messages claiming to be from any of your "postmaster@...", "abuse@..." or "webmaster@..." aliases or accounts to be authenticated before MDaemon will accept them. Spammers and hackers know that these addresses might exist, and may therefore attempt to use one of them to send mail through your system. This option will prevent them and other unauthorized users from being able to do so. For your convenience this option is also available on the

IP Shield honors aliases
By default the
513
will honor aliases when checking incoming messages for valid domain/IP pairs. The IP Shield will translate an alias to the true account to which it points and thus honor it if it passes the shield. If you clear this checkbox then the IP Shield will treat each alias as if it is an address independent of the account that it represents. Thus, if an alias
'
IP address violates an IP Shield then the message will be refused. This option is mirrored on the IP Shield screen — changing the setting here will be change it there as well.
Replicate aliases to LDAP address book
Click this check box if you want aliases to be replicated to the LDAP address book.
Alias replication is necessary for the LDAP remote verification feature to work reliably, but if you are not using that feature then replicating aliases to the LDAP address book is unnecessary. If you are not using remote verification then you can safely disable this feature to save processing time. For more information on remote
LDAP verification, see:

.
Aliases processing stops when result matches an existing account or list
When this option is enabled, alias processing will stop when the recipient of the incoming message matches an existing account or mailing list. This typically applies to aliases that include a wildcard. For example, if you have an alias set to,
"*@[email protected]," then this option will cause that alias to be applied only to addresses that do not actually exist on your server. So, if you also have the account, "[email protected]," then messages addressed to user2 would still be delivered to him because the alias wouldn't be applied to those messages.
But messages addressed to some non-existent account or list would be sent to
"[email protected]" because the wildcard alias would be applied to those messages. This option is enabled by default.
This option must be enabled when you are using
660
, to avoid potential problems with handling those messages.
Use recursive aliasing
Click this check box if you want to process aliases recursively. Any alias match causes the resulting value to be reprocessed back through the entire alias list—it is possible to nest aliases up to 10 levels deep. For example, you could set up something like this: [email protected] = [email protected]
[email protected] = [email protected]
[email protected] = [email protected]
This is logically identical to the single alias: [email protected] = user9example.org
It also means that: [email protected] = user9example.org

6.3.3 Autoresponders
6.3.3.1 Accounts
Accounts Menu 707
Autoresponders are useful tools for causing incoming email messages to trigger certain events automatically, such as running a program, adding the sender to a mailing list, responding with an automatically generated message, and more. The most common use of autoresponders is to reply to incoming messages automatically with a user-defined message stating that the recipient is on vacation, is unavailable, will reply as soon as possible, or the like. MDaemon users with
607
to
258
or
286
can use the options provided to compose auto response messages for themselves and schedule the dates they will be in use. Further, accounts with
BlackBerry devices activated on MDaemon's
378
can use the "Out of Office Reply" option under their device's email settings to configure their autoresponder. Finally, automated response messages are based on response scripts
(*.RSP files), which support a large number of macros. These macros can be used to cause much of the script's content to be generated dynamically, making autoresponders quite versatile.

Auto response events are always honored when the triggering message is from a remote source. However, for messages originating locally, autoresponders will only be triggered if you enable the Autoresponders are triggered by intra-domain mail option, located on the

Autoresponders are triggered by intra-domain mail
By default, both local and remote mail will trigger autoresponders. Clear this box if you do not wish mail that is sent from one local MDaemon domain to another to trigger them.
Limit auto responses to one per day per recipient
By default, autoresponders will only generate one response message per day for any given address. This prevents people from receiving the same redundant auto response message from you over and over again on the same day, every time they send you an email. Clear this box if you wish to send auto response messages each time someone sends you a message, even if they have already received one that day.
This option also helps to prevent message loops, which can occur when your auto response message is returned to an address that also has an autoresponder active. Instead of allowing both addresses to send auto response messages constantly back and forth to each other, this option would allow only one message to be sent to that address per day.

6.3.3.5 Creating Auto Response Scripts
Auto response scripts are text files that define the messages that are returned as the result of an autoresponder. These scripts are constructed as plain ASCII text files ending with the "*.rsp" file extension. When an auto response script is triggered by an autoresponder, the script file is processed and scanned for macros, which will then be replaced by actual data from the incoming message that triggered the response. Lines beginning with the "#" character are ignored and are used for comments.
There are several samples of scripts listed below, and there are several generic "*.rsp" files provided for you in MDaemon's \app\ folder.
Auto Response Script Macros
$HEADERS$
This macro will be replaced by all of the incoming message's headers. Text immediately preceding this macro will be duplicated at the start of each expanded line.
$HEADER:XX$
This macro will cause the value of the header specified in place of "xx" to be expanded in the message. For example: If the incoming message has
"TO: [email protected]" then the $HEADER:TO$ macro will expand to "[email protected]". If the original message has "SUBJECT: This is the subject
" then the $HEADER:SUBJECT$ macro would be replaced with the text "This is the subject".
$BODY$
This macro will be replaced by the entire message body. In an attempt to preserve character sets for different languages, MDaemon will read the message body as binary data rather than pure text, thus allowing a byte-for-byte copy of the message body.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 713
$BODY-AS-TEXT$
Like the $BODY$ macro, this macro will be replaced by the entire message body, but as text rather than binary. Text immediately preceding this macro will be duplicated at the start of each expanded line. So, using ">>$BODY-AS-TEXT$" in a script would place each line of the original message into the generated message, but each line would begin with ">>". Text can also be added to the right of this macro.
$SENDER$
This macro resolves to the full address contained in the incoming message's "From:" header.
$SENDERMAILBOX$
This macro resolves to the mailbox of the sender.
The mailbox is the portion of the email address to the left of the "@" symbol.
$SENDERDOMAIN$
This macro resolves to the domain of the sender.
This is the portion of the email address to the right of the "@" symbol.
$RECIPIENT$
This macro resolves to the full address of the message recipient.
$RECIPIENTMAILBO
X$
This macro resolves to the mailbox of the message recipient. The mailbox is the portion of the email address to the left of the "@" symbol.
$RECIPIENTDOMAIN
$
This macro resolves to the domain of the message recipient. The domain is the portion of the email address to the right of the "@" symbol.
$SUBJECT$
This macro resolves to the value of the "Subject:" header.
$MESSAGEID$
This macro resolves to the value of the "Message-
ID
" header.
$CONTENTTYPE$
This macro resolves to the value of the "Content-
Type
" header.
$PARTBOUNDARY$
This macro resolves to the value of the MIME "Part-
Boundary" value found in the "Content-Type" header for multipart messages.
$DATESTAMP$
This macro expands to an RFC-2822 style date-time stamp line.
$ACTUALTO$
Some messages may contain an "ActualTo" field which generally represents the destination mailbox and host as it was entered by the original user prior
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
714 MDaemon Messaging Server 17.0
to any reformatting or alias translation. This macro expands to that value.
$ACTUALFROM$
Some messages may contain an "ActualFrom" field which generally represents the origination mailbox and host prior to any reformatting or alias translation. This macro expands to that value.
$REPLYTO$
This macro resolves to the value found in the
"ReplyTo" header.
$PRODUCTID$
This macro expands to the MDaemon version information string.
$AR_START$
Returns the auto-responder start date/time.
$AR_END$
Returns the auto-responder end date/time.
Header Replacement Macros
The macros listed below control the auto response message's headers.
%SetSender%
ex: %SetSender%[email protected]
Just for the purpose of the auto-response message, this macro resets the sender of the original message before constructing the auto-response message headers. Thus, this macro controls the auto-response message's TO header. For example, if the sender of the original message were "[email protected]" and recipient's autoresponder used the %SetSender% macro to change it to "[email protected]" then the auto-response message's TO header would be set to "[email protected]."
%SetRecipient%
ex: %SetRecipient%[email protected]
Just for the purpose of the auto-response message, this macro resets the recipient of the original message before constructing the auto-response message headers.
Thus, this macro controls the auto-response message's FROM header. For example, if the recipient of the original message were "[email protected]" and Michael's account had an autoresponder using the %SetRecipient% macro to change it to
"[email protected]," then the auto-response message's FROM header would be set to "[email protected]."
%SetReplyTo%
ex: %SetReplyTo%[email protected]
Controls the value of the auto-response message's ReplyTo header.
%SetActualTo%
ex: %SetActualTo%[email protected]
Sets who the "actual" recipient of the message will be.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Accounts Menu 715
%SetSubject%
ex: %SetSubject%=Subject Text
Replaces the value of the original message
' s subject.
%SetMessageId%
ex: %SetMessageId%=ID String
Changes the ID string of the message.
%SetPartBoundary%
ex: %SetPartBoundary%=Boundary String
Changes the part boundary.
%SetContentType%
ex: %SetContentType%=MIME type
Changes the content-type of the message to the declared value.
%SetAttachment%
ex: %SetAttachment%=filespec
Forces MDaemon to attach the specified file to the newly generated auto-response message. Only files specified on the
709
screen can be attached to autoresponders.
6.3.3.5.1 Auto Response Script Samples
A simple auto response script, using several auto response script macros, might be called VACATION.RSP and look like this:
Greetings $SENDER$
Your message regarding '$SUBJECT$' won't be read by me because I'm on vacation. Hurray!!!
Yours truly,
$RECIPIENT$
You can also use some of the header replacement macros to expand this script and control the headers that will be generated when the auto response message is mailed back to $SENDER$:
Greetings $SENDER$
Your message regarding '$SUBJECT$' won't be read by me because I'm on vacation. Hurray!!!
Yours truly,
$RECIPIENT$
%SetSubject%=RE: $SUBJECT$
%SetAttachment%=c:\photos\me_on_vaction.jpg
Using that script the auto response message will have "RE: " added to the beginning of the subject and have the specified file attached.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
716 MDaemon Messaging Server 17.0
The "%SetSubject%=RE: $SUBJECT$" line is handled like this:
1. The $SUBJECT$ portion is expanded and replaced by the original message's subject text. This makes the string equivalent to:
%SetSubject%=RE: Original Subject Text
2. MDaemon replaces the original subject, which it has stored in its internal buffers, with this newly calculated one. From that point forward, any use of "$SUBJECT$" in the script will return the new result.
Note the placement of the new macros - they are listed at the bottom of the response script. This is needed to avoid side effects. For example, if the %SetSubject% macro were placed before the $SUBJECT$ macro, which appears in the second line of the response script, the subject text would have already been changed by the time the
$SUBJECT$
macro was expanded. Therefore, instead of replacing $SUBJECT$ with the content of the original message's "Subject:" header, it would be replaced with whatever you have set the value of %SetSubject% to be.

system.
Account Database Type
Store account data in USERLIST.DAT disk file
Choose this option if you want MDaemon to use its internal
USERLIST.DAT
file as the account database. This is MDaemon
' s default setting and causes all of the MDaemon user account information to be stored locally. Most information is stored in a single file, which is memory resident to increase efficiency and speed.
Store account data in LDAP accessible store
Choose this option if you want MDaemon to use your LDAP server as the MDaemon user database rather than ODBC or its local
USERLIST.DAT
system. You might want to use this method of maintaining your user account data if you have multiple
MDaemon servers at different locations but want them to share a single user database. Each MDaemon server would be configured to connect to the same LDAP server in order to share user information rather than storing it locally. LDAP servers typically respond quickly and efficiently to queries but are slower to update or insert new data.

The default value in this option is "0", which means that passwords never expire. But if you set it to, for example, 30 days then the user will have 30 days to change his or her password,
starting from the last time the account's password was changed. Therefore when you initially set an expiration value, any account with a password that hasn't been changed within the specified number of days will immediately have an expired password. When a user's password expires he or she will not be able to access POP,
IMAP, SMTP, WorldClient, or Remote Administration. The user can, however, still connect to WorldClient or Remote Administration where he or she will then be required to change the password before proceeding. Email clients such as Outlook,
Thunderbird, and the like cannot be used to change the password. Further, many clients will not even show a helpful error message to users, therefore they may need administrator assistance to figure out why their login is failing.

726 MDaemon Messaging Server 17.0
In order for users to be able to change their passwords via
WorldClient or Remote Administration they must first be granted the "...edit password" web access permission on the
673
screen. Further, because changing the password may not be easy or possible for some users, you should exercise caution before using this option.
Warn users of password expiration each day for [xx] days (0 = never)
Accounts with a password that is about to expire can receive a daily reminder email that the password needs to be changed. Use this option to designate the number of days before the password expires that you want MDaemon to start sending these daily emails.
Remember this many old passwords (0=none)
Use this option to specify the number of old passwords that you want MDaemon to remember for each user. When users change their passwords they will not be allowed to reuse old passwords. This option is set to "0" (disabled) by default.
Store mailbox passwords using non-reversible encryption
Check this box if you want MDaemon to store passwords using non-reversible encryption. This protects the passwords from being decrypted by MDaemon, the administrator, or a possible attacker. To do this, MDaemon uses the bcrypt password hashing function, which allows for longer passwords (up to 72 characters), and for passwords to be preserved yet not revealed when exporting and importing accounts. Some features, however, are not compatible with this option, such as weak password detection and APOP & CRAM-MD5 authentication, because they depend on MDaemon being able to decrypt passwords. Non-reversible passwords is disabled by default.

Accounts Menu 727
Quotas Settings
Include all email folders in quota calculation (needed for IMAP users)
When this box is checked, all message files in all email folders under a user
' s account will apply toward any size or message number limitations placed on that account.
Otherwise, only message files in the inbox will count toward those limitations. This is generally only needed for IMAP users.
...include Calendar, Contacts, Tasks, Documents, folders as well
Click this check box if you wish to include all calendar, contacts, tasks, and documents folders in the quota calculations.
Refuse incoming messages sent to over quota accounts
By default, when an account has a message quota restriction placed on it and the quota has been reached, MDaemon will no longer accept any incoming messages for the account until the account holder deletes some of his or her stored mail. Clear this checkbox if you do not wish to refuse incoming messages for over quota accounts.
Refuse outgoing messages sent from over quota accounts
Check this box if you wish to refuse outgoing messages sent from any account that has reached its quota. An over-quota account will no longer be able to send mail until some of its stored messages have been deleted. This option is disabled by

default.
SMTP server sends 552 when account is over quota (otherwise sends 452)
By default, when an account is over
618
MDaemon sends the 452 error code
(i.e "Requested action not taken: insufficient system storage") during the SMTP process. This code generally means that the server should try again later. Check this box if you wish to send the permanent failure 552 error code instead
("Requested mail action aborted: exceeded storage allocation").
Quota Report and Warnings
Email a warning to user if this percent of their quota is reached
If, during the
daily maintenance and cleanup event
413
, MDaemon determines that an account is exceeding this percentage value of either its Maximum number of
messages stored at once or Maximum disk space allowed quota restriction designated on the
618
, a warning message will be sent to the account. Use the Subject text (near quota) option below to set the Subject for the message. The message will list the account’s current number of stored messages, the size of its mailbox, and the percentage used and the percentage remaining.
Further, if an existing warning is found in the account’s mailbox it will be replaced with an updated message. Disable this option if you do not wish to send the quota warning message to users.
Subject text (near quota)
This is the Subject text of the warning messages sent to any users who exceed the quota percentage designated above. These messages are sent each day during the daily maintenance and cleanup event, which occurs at midnight by default.
Subject text (over quota)
Like the "near quota" warning message, another message will be sent when a user's account exceeds the quota. This is the Subject text of the "over quota" warning message.
Send daily quota report to global and domain administrators
Check this box and specify a value if you wish to send a daily quota report to all global and domain administrators. The report will contain quota statistics for all users at or over the designated percentage of their quota restriction. Use "0" as the value if you want the report to include quota statistics on everyone.
Subject text (daily report)
Use this option if you wish to customize the subject text of the daily quota report that MDaemon sends to the administrators. See QuotaReport.dat in the MDaemon
\APP
folder if you wish to customize the report itself.
Inactive Accounts

6.3.4.5 Minger
Located under A ccounts » A ccount S etti ng s , Minger is an email address verification protocol created by Alt-N Technologies. Originally based loosely on the Finger protocol,
Minger is primarily intended to provide a simple and efficient mechanism for allowing others to query your server in order to verify whether or not an email address is valid.
For efficiency Minger uses UDP rather than TCP, and for security it can require authentication—though it supports anonymous queries as well. The Minger dialog is used to enable/disable MDaemon's Minger server, designate the port that it will use
(the default is 4069), and choose whether to require authentication via a shared secret
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
730 MDaemon Messaging Server 17.0
system or to allow anonymous queries.
MDaemon also has a Minger client, which is built in to the Domain Gateways system
(see
202
). Each domain for which MDaemon is acting as a gateway or backup server can be configured to use Minger so that MDaemon will connect to the remote server and verify whether or not the recipients of incoming messages for that domain are valid. This prevents you from having to assume that all recipients are valid addresses.
You can find the latest draft of the Minger protocol at:
http://tools.ietf.org/html/draft-hathcock-minger-06
Minger Server
Enable Minger server
Click this checkbox to enable MDaemon's Minger server.
Listen for Minger connections on this UDP port
This is the port on which the Minger server will listen for connections. The Internet
Assigned Numbers Authority (IANA) has reserved and assigned TCP and UDP port
4069 for use with Minger clients and servers. Changing this port is not recommended as it has been reserved exclusively for Minger use.
Minger queries require a shared secret
If you wish to require authentication via a shared secret system, choose this option and enter a text string of at least 16 characters. When this option is chosen the
Minger server will refuse unauthenticated queries.
Minger server supports anonymous queries
Choose this option if you wish to support anonymous Minger queries—the connecting client isn't required to authenticate itself before making address verification queries.
This is similar to what can be accomplished now by sources using the
SMTP VRFY
command or SMTP "call back" or "call forward", but it is much more efficient and doesn't result in lots of dropped SMTP sessions over TCP, SMTP logs cluttered with dropped sessions, and similar problems inherent in those methods.
Minger treats foreign aliases as active email addresses
When this box is checked, Minger will treat foreign aliases (aliases that point to external addresses) as if they were active known addresses. Also, this behavior is forced when a query comes from SecurityGateway to MDaemon regardless of the state of this option's setting.
Cache Minger lookup results
By default MDaemon will cache Minger lookup results. If you do not wish to cache them, disable this option.

6.4 Importing Accounts
6.4.1 Importing Accounts from a Text File
Click the A ccounts » I mporti ng ... » I mport accounts from a comma deli mi ted tex t fi le. . .
menu selection to access this account generation feature. It can also be reached by clicking the
Import
button on the Account Manager. This is a simple method for importing and automatically generating mail accounts. MDaemon will read a text file and generate new mail accounts using as little as just the first and last names of the user. If you are careful to setup your account template strings properly (see
667
) you can generate unique accounts using only the first and last names, but you can also include many other options for specific user settings if you want to override the new account defaults. All fields must be separated by commas.
Each line of the comma delimited text file must contain only a single user's entry. The first line must be a base line giving the names and sequence of the fields in subsequent lines. A sample file would look something like this:
"Mailbox", "FullName", "MailDir", "AllowAccess"
"arvel", "Arvel Hathcock", "C:\Mail\Arvel\", Y
"michael", "Michael Mason", "C:\Mail\Michael\", N
The field names in the base line are used by MDaemon to determine the data sequence and can therefore appear in any order. Each of the field names must be in quotes.
All "String" values must be contained in quotes, and a "bool" field value is considered FALSE unless the first char is: y, Y, 1, t
, or T.
First, middle, and last names are acceptable in each full name.
However, you may not use commas in them.
After running the import process, MDaemon will create
TXIMPORT.LOG
, detailing the import results and listing which accounts imported successfully and which failed. Typical reasons why an account might not be imported would include a conflict with an existing account's mailbox, name, or directory information, a conflict with an existing alias to an account, or a conflict with a mailing list name.
See the description of the
MD_ImportUserInfo()
and the
MD_ExportAllUsers()
within the
MD-API.HTML
file located in your
\API\
directory, for more information on the field mappings.
Use the following values in the base line to map to MDaemon account fields:

6.4.2 Windows Account Integration
MDaemon supports Windows Account integration. This support consists of a SAM/
Active Directory import engine, which can be reached from MDaemon's Accounts menu
(A ccounts » I mporti ng ... » I mport accounts from S A M /A cti v e di rectory...).
Additionally, support for Active Directory (AD) authentication of users is embedded into the MDaemon user management code. It is possible to specify a Windows domain in an account’s password field and then MDaemon will dynamically authenticate such accounts in real-time, using the specified Windows domain’s security system. Under such a scheme, changing the account’s password in Windows user management will automatically update MDaemon. Therefore, your users will only have to remember one set of authentication credentials. This also makes for very easy account setup for new installations.
The security context of the account running MDaemon must have the S E_ TCB _ N AM E privilege (i.e. “To act as part of the
Operating System”). If the process is a service running in the
Local System account, it will have this privilege by default.
Otherwise, it must be set in the Windows user manager for the account under which MDaemon is running.

Use the account template to generate passwords
This option causes MDaemon to generate passwords for imported accounts using the
account template settings (see Account Defaults

).
Set account passwords equal to account names
This switch causes MDaemon to use the account name as the account password.
Make every password equal to…
This switch allows you to specify a static password value that will be used by all imported accounts.
Authenticate passwords dynamically using SAM/AD
This switch enables AD authentication of imported accounts. Rather than specifying a password MDaemon will simply authenticate the mail client supplied USER and
PASS values using the NT database in real-time.
Authenticate on this Windows domain
Enter the name of the Windows domain that MDaemon will use when authenticating connections dynamically.
This is not the machine name of the domain controller. It is the actual name of the Windows Domain.
When accounts are configured for AD authentication, the name of the Windows domain preceded by two backslash characters is used in the account's PASSWORD field and is stored unencrypted within the USERLIST.DAT file. For example, if an account is configured for AD authentication on a Windows domain called ALTN, the account's password field will contain the value \\ALTN. The two backslash characters preceding the domain name signify to MDaemon that the password field actually contains the name of a Windows domain and that
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
736 MDaemon Messaging Server 17.0
MDaemon should attempt to authenticate the USER and PASS values provided by the mail client using that domain's account database. For that reason you must not start a password with two backslash characters unless the account is configured for
AD authentication as described above. In other words, you can't just have regular passwords that start with two backslashes. Passwords beginning with two backslashes are always assumed to be providing a Windows domain name and not a password.
You may enter the two backslashes and Windows domain name combination into an account's password field on the
601
screen of the Account Editor. You need not restrict yourself to using the importer in order to setup accounts for
AD authentication.

Use the Catalog s » New Catalog ... or Catalog s » Edi t Catalog ... menu selection to open the Catalogs Editor for creating or editing a file catalog. Catalogs give users the ability to request files across the network and have them encoded and mailed back to them. Catalogs work by allowing the mail administrator to assign a "magic name" (i.e.
shortcut) to files on disk. Magic names are like aliases which point to a specific file located somewhere accessible to MDaemon. A user can then use a special type of email message to request the file using the magic name. The format of this email message is described in the

8.1.1 Retry Queue
The Retry Queue dialog, located under Queues » M ai l Queues , is used to determine how MDaemon will handle messages that cannot be delivered due to some non-fatal error, such as when the receiving server is temporarily unavailable.
Retry Queue
Keep message in the remote queue for at least XX minutes
This setting governs the length of time a message will remain in the remote queue before being removed and placed in the retry queue. The remote queue will generally attempt to deliver the message more frequently than the retry queue.
Retry sending undeliverable mail once every xx minutes
This setting determines how frequently the messages in the retry queue are processed.
Inform the sender when message delivery is delayed
By default MDaemon will inform the sender when a message could not be delivered due to some temporary error, causing it to be placed in the retry queue. Uncheck

Queues Menu 743
this box if you do not wish to inform the sender of the delay.
Inform the sender when previously delayed messages are delivered
Check this box if you wish to inform the sender when a delayed message has finally been delivered. This is disabled by default.
Undeliverable Mail
Route message to bad queue if hop count exceeds (5-100)
RFC standards stipulate that a mail server must stamp each message each time that it is processed. These stamps can be counted and used as a stopgap measure against recursive mail loops that can sometimes be caused by errant configurations.
If undetected, these looping message delivery cycles will consume your resources.
By counting the number of times the message has been processed, such messages can be detected and placed in the bad message directory. The assumption is that if a message hasn't reached its recipient after being processed by a given number of mail servers then there is probably a mail loop in progress. Most likely, the default setting of this control should be sufficient to prevent mail loops and will not need to be changed.
If a message is still undeliverable after xx days then:
This setting determines the number of days that a message can remain in the retry queue before being removed. If you enter "0" days into this option then the message will be bounced back after the first retry attempt. The default setting is 2 days.
Route message to the bad message queue
When this option is enabled, a message will be moved to the bad message queue once it has reached the time limit set in the "If a message is still undeliverable
after xx days then:" option.
Inform the sender that the message could not be delivered
Once a message has reached the time limit set in the "If a message is still
undeliverable after xx days then:" option, this switch will cause MDaemon to send a
749
message to the sender informing him that the message has been permanently removed from the server.
Inform the postmaster that the message could not be delivered
If this switch is enabled, the postmaster will be notified when a message has been permanently removed from the retry system.
. . . unless it
' s an MDaemon auto-generated message
By default, the retry system will not inform the postmaster that a message could not be delivered when that message was auto-generated by MDaemon.
Clear this checkbox if you wish to inform the postmaster about the failure of those messages as well. Examples of auto-generated messages are returnreceipt notifications, Autoresponder generated messages, results of account processing, and so on.
Route messages with no recipients to the bad message queue
When this option is enabled, messages with no recipient data will be moved to the bad message queue. When disabled, they will be deleted. This option is enabled by

8.1.2 Holding Queue
The Holding Queue, located under Queues » M ai l Queues can be used to receive messages that cause software exceptions during AntiVirus, AntiSpam, or Content Filter processing. If a software error occurs when processing a message it will be moved into the holding queue and not delivered.
Messages placed into the holding queue will stay there until the administrator takes some action to remove them. There is a
Process Holding Queue
button on MDaemon's toolbar and an identical option on the Queues menu bar. You can also process the messages by right-clicking the holding queue on the main interface and then selecting
"Re-Queue" from the right-click menu. Processing the holding queue will move all of its messages into either the remote or local queues for normal mail processing. If the error that caused a message to be placed into the holding queue still exists then that message will be placed back into the holding queue when the error reoccurs. If you want to attempt to deliver the holding queue
' s messages regardless of any error which might occur, then you can do so by right-clicking the holding queue on the main interface and then selecting "Release" from the right-click menu. When releasing messages from the holding queue a confirmation box will open to remind you that the messages could contain viruses or otherwise not be able to filter properly through the
Content Filter, AntiSpam and/or AntiVirus engines.

8.1.5 DSN Settings
Queues Menu 749
When MDaemon has a problem delivering a message, whether it is a temporary or permanent delivery failure, a Delivery Status Notification (DSN) message is sent to the sender of the message. This screen contains various options related to those DSN messages. It is located at: Queues » M ai l Queues /DS N... » DS N S etti ng s .
DSN Content
Transient (delayed) delivery message subject text (up to 512 chars)
This is the subject heading of the DSN message that will be sent when there is a transient problem causing a delay in message delivery. For example, if the recipient's mail server isn't available when MDaemon tries to deliver a message, MDaemon will continue trying to send it at designated intervals, and it will send this DSN message informing the sender of the problem. See:
750
.
Permanent (failed) delivery message subject text (up to 512 chars)
This is the subject heading of the DSN message that will be sent when there is a problem that makes it impossible for MDaemon to deliver a message. For example, if the receiving mail server rejects the message, stating that the recipient's email address doesn't exist, MDaemon will stop trying to deliver the message and will send a DSN message informing the sender that the message cannot be delivered.

When this option is enabled, forwarded messages that encounter permanent, fatal delivery errors or expire from the
742
will be moved to the bad messages queue, with no DSN messages being sent to the original sender. This option is enabled by default.
Place undeliverable DSN messages into bad message queue
Click this checkbox if you wish to place undeliverable Delivery Status Notification messages into the bad message queue rather than retrying them.
This only applies to DSN messages generated by MDaemon.
DSN messages are sent through the content and spam filters
Enable this option if you wish to send DSN messages through the content and spam filters. This option is disabled by default.
Customizing DSN Messages
The "human-readable" portion of transient (delayed) and permanent (failed) DSN messages can be customized by creating a file called DSNDelay.dat or DSNFail.dat
respectively, in the \MDaemon\App\ folder. Edit them with a text file editor such as
Notepad and enter the text you wish to use. The following macros can be used in your custom text:
$SESSIONID$ - expands to the delivery session's ID string
$QUEUEID$ - expands to the message's mail queue ID string
$MESSAGEID$ - expands to the message-id header value
$RETRYDAYS$ - length of time allowed in queue (in days)
$RETRYHOURS$ - length of time allowed in queue (in hours)
MDaemon must be restarted before changes to these files are loaded.

8.2 Pre/Post Processing
Queues Menu 751
Local and Remote Queue Pre/Post Processing
Just before processing the (local/remote) mail queue run this program
This field specifies a program path and name that will be executed just prior to the processing and delivery of any RFC-2822 messages that might be in the local or remote message queues. If complete path information is not provided, MDaemon will first search for the executable in the MDaemon directory, then in the Windows
System directory, next in the Windows directory, and finally the directories listed in the PATH environment variable.
...suspend all operations for xx seconds
The value entered here determines how MDaemon will behave while the specified program is in progress. MDaemon can be configured to pause its execution thread for the number of seconds specified while waiting for the process thread to return. If the process returns before the number of seconds has elapsed, MDaemon will resume its execution thread immediately. If you enter "0" in this option MDaemon will not suspend operations at all. Entering "-1" will cause MDaemon to wait until the process returns, no matter how long that might be.
Do not execute when queue is empty
Enable this switch if you do not want the specified program to run when the queue is empty.

8.3 Queue and Statistics Manager
MDaemon
' s Queue and Statistics Manager is accessed from within MDaemon under the
Queues » Queue and S tati s ti cs M anag er menu selection. The Queue and Statistics
Manager is made up of a four-page dialog. Each of these pages has been designed to serve a distinct and specific purpose while also maintaining a simple format that makes them very easy to use.
Queue Page
753
The default tab is the
Queue Page
. From this page you can easily manage all of
MDaemon
' s standard mail queues, as well as the User Account mailbox folders. By simply clicking on the queue or user of your choice, a list of all message files contained within the specified queue will be displayed along with several key pieces of pertinent information about each message: the sender, the recipient, the content of the
"Deliver-To" header, the subject of the message, its size, and how long it has been at its current location. In addition, controls are provided that make it easy to copy or move messages between folders, or delete them completely.
User Page
756
The
User Page
displays a list of all MDaemon users. This list includes their full name, mailbox name, the number of messages in their mailbox, the amount of disk space that their account is taking up, and the date that they last checked their mail. This list can also be saved to disk as a text file, or it can be saved in comma delimited format for use with databases.
Log Page
758
With this dialog you can display MDaemon
' s
Log Files
in a simple list format. This feature is very useful for quickly examining the history of MDaemon
' s mail transactions because it condenses the selected
Log File
into a columnar list which contains: the Type of the message (POP Inbound, DomainPOP, RFC2822, and so on), the Host to which MDaemon connected during the transaction, the sender, the recipient, the message size, the date that each message was processed, and whether or not the transaction was successful. You can also examine the detailed portion of the log regarding any of the entries on the list by double clicking the desired entry. This will display the portion of the log where that transaction was made. Logs displayed on the
Log Page
can be saved as a text file or in comma delimited format for use with databases.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Queues Menu 753
Report Page
760
The last tab is the
Report Page
. With this feature you can produce a report containing all of MDaemon
' s configuration settings, written in a plain text readable format. Because of the large number of optional settings and configurations in MDaemon, this can greatly speed the process of administering configuration changes as well as aid in diagnosing possible configuration problems. Additionally, this report is displayed in a text editable format that makes it possible to Copy/Paste the information it contains
(using the right-click shortcut menu), or add notations or other information to the file before saving it.
8.3.1 Queue Page
Queue page list box
When a queue or user is chosen from the
Message Queues
area or the user list box beside it, a list of all message files contained within the selected queue will be displayed in the main list box on this page. This list contains each message
' s file name, the sender, the recipient, the content of the "Deliver-To" header, the subject of the message, its size, and how long it has been at its current location (listed by date and time).
Above this box the complete file path to the currently displayed directory is given, as well as the number of messages displayed and the size of the directory.
You may copy, move, or delete one or more files by selecting them from the list and then clicking the appropriate button below it.
The content of these files may also be edited directly from the
Queue Page
list box.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
754 MDaemon Messaging Server 17.0
Simply double-click the file that you wish to edit (or choose "Edit" from the right-click shortcut menu) and the file will be opened in Notepad for editing.
If you want the Queue and Statistics Manager to open an editor other than Notepad by default, then you must edit the mdstats.ini
file located in the \MDaemon\app\ folder.
Change the "Editor=" key located under the [QueueOptions] section heading to Editor=MyEditor.exe. If the file path of the *.exe file is not in your current path, then you will have to include the path here as part of the file name.
The list box can be navigated by using the vertical or horizontal scroll bars, or you can click anywhere within the list box and use the ARROW keys for navigation. You can sort information contained in the
Queue Page
list box by whichever column you choose.
Simply click once on the desired column to sort it in ascending order (A-Z, 1-2), or click twice to sort it in descending order (Z-A, 2-1). Columns can also be resized by positioning the pointer over the line between any of the column headings until it changes shape and then dragging the column to the desired width.
Selecting Files
To select files individually
To select contiguous files
Click the desired file.
Click the first file in the contiguous list of files that you wish to select, then while holding down the
SHIFT key, click the last contiguous file in the desired list.
Alternatively, you may use the ARROW, HOME, END,
PAGE UP, and PAGE DOWN keys, while holding down the SHIFT key, to select files in contiguous order.
To select non-contiguous files
Click on the desired files in the File Name column while holding down the CTRL key.
Message queues
Click an in the lower left pane and a list of all files contained within the specified queue will be displayed in the
Queue Page
list box
.
If you click the
User Folders
option, a list of all MDaemon users will be displayed in the
User List Box
to the right of the
Message Queues
section.
Users list box
This box displays a list of all MDaemon users when the
User Folders
option is clicked in the
Message Queues
section (lower left pane). Click a user
' s name to display a list of all message files currently contained in the user
' s mailbox folder.
Refresh
Because mail queues are dynamic while MDaemon is active - with message files constantly being transferred to and from them - you should regularly click this button to refresh any list of files that you may have displayed.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Queues Menu 755
You can edit the MDstats.ini file to cause displayed lists to automatically refresh. To do this simply open the MDstats.ini
file located in MDaemon's \app\ directory and edit the
AutoRefresh key under the [QueueOptions] heading to reflect the number of seconds that you wish to elapse between refreshes. Entering the value "0" means that you do not want the list to automatically refresh. Example: AutoRefresh=15
(the list would refresh every 15 seconds).
Copy
When one or more files are selected, click this button to copy the selected files to another queue or user
' s mailbox folder. After clicking this button the
Copy Message(s)
dialog box will open, from which you can select the desired location to which you wish to copy the selected files.
Move
When one or more files are selected, click this button to move the selected files to another queue or user
' s mailbox folder. After clicking this button the
Move Message(s)
dialog box will open, from which you can select the desired location to which you wish to move the selected files.
Files copied or moved to other queues will rarely retain their original file names. To avoid overwriting files of the same name that may already be in the queue, MDaemon always calculates the next destination filename based on the HIWATER.MRK file located in the destination folder.
Delete
When one or more files are selected in the
Queue Status List Box
, click this button to delete the selected files. After clicking this button a confirmation box will open asking if you really do wish to delete the selected files.
Mail queues are dynamic while MDaemon is active - with message files constantly being transferred to and from them.
For this reason you should be aware that when copying, moving, or deleting files you may at times encounter a message stating that the action that you are attempting cannot be completed. This will occur when the message file that you are attempting to work with has already been removed by MDaemon before the desired action has begun. By clicking the Refresh button, you can update the current list of files displayed in the list box.
You can prevent messages from being moved out of the queue while you are editing them by editing the MDstats.ini file. To do this simply open the MDstats.ini file located in MDaemon's
\app\
directory and change the LockOnEdit=No key under
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
756 MDaemon Messaging Server 17.0
the [QueueOptions] heading to LockOnEdit=Yes. This will cause a LCK file to be created whenever you are editing a message, which will prevent it from being moved out of the queue until you are finished with it.
8.3.2 User Page
User information
When the
User Page
is chosen, a list of all MDaemon accounts is loaded into the
User
Information
list box
.
This list contains each user
' s full name, the name of their mailbox, the domain to which the account belongs, the number of messages it contains, its mail format, the amount of disk space (in kilobytes) that the account is taking up, their forwarding address, and finally, the date that their mail was last checked.
Given that the information contained in this list is constantly changing, it can be easily updated by clicking the
Refresh
button.
The list box can be navigated by using the vertical and horizontal scroll bars, or you can click anywhere within the list box and use the ARROW keys for navigation. You can sort information contained in the
User Information
list box by whichever column you choose. Simply click once on the desired column to sort it in ascending order
(A-Z), or click twice to sort it in descending order (Z-A). Columns may also be resized by positioning the pointer over the line between any of the column headings until it changes shape and then dragging the column to the desired width. Further, you can double-click any entry and MDStats will be shifted to the
Queue Page
with the contents of their mailbox folder displayed.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Queues Menu 757
By default, the list displays the Message Count not file count, and the Disk Space used by messages not the space used by all files in the directory. This is the Quota information reported by
MDaemon. Alternatively, you can display the file count and disk space used by all files instead of by messages. To change this setting simply open the MDstats.ini file located in MDaemon's
\app\
directory and change the ShowQuota=Yes key under the [UserOptions] heading to ShowQuota=No.
User folders contain a file called "hiwater.mrk" which is used to determine some of this user information. You should avoid deleting this file unnecessarily as it will prevent the Queue and
Statistics Manager from being able to obtain some of the information listed in the User Information list box.
Refresh
User statistics such as the number of messages contained in their mailboxes, and the amount of disk space that their accounts are using, are constantly changing.
You can easily update the information contained in the
User Information
list box by clicking the
Refresh
button. This will immediately make all displayed information current.
Progress indicator
Because
User Information
lists can at times be very large, below the
User Information
list box is a progress indicator bar that provides a visible indication that the program is still operating when large files are being loaded.
Save
The information contained in the
User Information
list box can be saved as a file in comma delimited format for use with databases, or as a plain ASCII text file by clicking the
Save
button. After choosing a name and location for this file in the
Windows Save As dialog, you will be asked whether you want to save the file in comma delimited format or as a plain text file.

8.3.3 Log Page
Log report
The
Log Report
list box displays MDaemon
' s detailed log files that you select through the
Open Log
button and the Windows Open dialog that follows it. The
Log Report
display provides a quick and easy way to review the history of mail transactions that
MDaemon has processed without having to sort through the large volume of information that MDaemon log files may sometimes contain. When a
Log Report
is displayed in this list box the Queue and Statistics Manager breaks it down into a simple format containing: the Type of the message (POP Inbound, DomainPOP,
RFC2822, and so on), the Host to which MDaemon connected during the transaction, the sender, the recipient, the message size, the date that each message was processed, and whether or not the transaction was successful.
You can also examine the detailed portion of the log regarding any of the entries on the list by double clicking the desired entry. This will display the portion of the log where that transaction was made. Using the right-click shortcut menu you can copy/paste this detailed log portion to a text editor for saving or editing should you desire to do so.
The list box can be navigated by using the vertical and horizontal scroll bars, or you can click anywhere within the list box and use the ARROW keys for navigation. You can resize the list box
' s columns by positioning the pointer over the line between any of the column headings until it changes shape and then dragging the column to the desired width.
The Log Page will display log files that have been compiled using either the Log detailed mail sessions or the Log summarized

mail sessions option loc ated under L og g i ng » L og M ode.
However, we highly recommend that you use the Log detailed
mail sessions option. When using the Log summarized mail
sessions format you will find that there is very little information that will be displayed in your Log Report. Because the Log Page itself condenses the detailed log into a summary view of
MDaemon's activity, while still providing the ability to look at the detailed view of every transaction when necessary (by double-clicking an entry), there is no need to have MDaemon summarize the log file while compiling it.
Open log
Click this button to open the Windows Open dialog for choosing which log file that you wish to view. If you click this button when there is a
Log File
already displayed in the
Log Report
list box, you will be given the option to append the new file to the one that is already displayed.
After a log is displayed, a message box will be opened which contains a summary of the selected log. When saving a Log Report as a text file, this log summary will be appended to it.

9 Additional MDaemon Features
9.1 MDaemon and Text Files
MDaemon uses a number of plain text files to store some of its data, system generated message templates, and configuration settings, which provides a great deal of flexibility. You can create new text files from within MDaemon by using the Fi le » New menu selection. This can be useful for quickly creating data files for use with
Autoresponders and various other MDaemon features, such as RAW files.
Editing MDaemon Files
MDaemon's various data files are plain text and can be edited in Notepad. You can easily open any of these files from within MDaemon by using the Fi le » Open » Empty
T ex t Fi le
menu selection. By default this looks in MDaemon's \app\ folder for *.txt
files. Switch the Files of type: drop down list to "All files" to see the rest of the files contained in that folder.
9.2 Remote Server Control via Email
Many functions of MDaemon can be accessed remotely using the email transport system itself, by sending a specially formatted email to the MDaemon system account,
"MDaemon@<MDaemon's Domain>". Messages sent to the server are stored in the server's message directory just like any other user.
Some of these control messages require a valid account on the server. For those commands which require a valid account, the message must be authenticated during the SMTP process using SMTP AUTH.
There are two, broad categories of commands that can be used in email messages:
766
, and
769
.
See:
Mailing List and Catalog Control
766
769
9.2.1 Mailing List and Catalog Control
None of these commands require an account on the server. Parameters contained in
[brackets] are optional. For example: "name [address]" could be entered as "Michael" alone or with the optional parameter added: "Michael [email protected]". Messages should be sent to "mdaemon@[MDaemon domain]" with the each command and associated parameters contained on a single line in the body of the message.

9.3 The RAW Message Specification
9.3.1 The RAW Message Specification
MDaemon has inherent support for a simple and powerful mail message format known as
RAW mail. The purpose of the RAW mail system is to provide a simple and standard format that software systems such as MDaemon can use to create much more complex
RFC-2822 compliant message. Use of mail transport agents such as RAW allow client
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
770 MDaemon Messaging Server 17.0
software to offload to the server all the complicated work of maintaining adherence to
Internet mail standards.
RAW mail consists of a series of required and optional text headers followed by a message body. Most headers consist of a token followed by a value enclosed in <> symbols. Each header line ends with a <CRLF> combination of characters. Headers are separated from the message body by a blank line and are case insensitive, and the
from
and
to
headers are the only ones that are required. All text, headers and body, are plain
ASCII text and must be contained in a file that ends with the extension, ".raw" (for example "
my-message.raw
"). Then, to queue the message for delivery, place the
*.raw
file in MDaemon
' s RAW queue (typically located at, "C:\MDaemon\Queues\Raw").
Bypassing the Content Filter
By default, RAW messages are passed through the Content Filter like normal messages.
If you want a given RAW message to bypass the filter then start the name of the file with "
p
" or "
P
". For example, "
P_my-message.raw
" would bypass the Content Filter but "
my-message.raw
" would be processed through it normally.
Bypassing the Content Filter will prevent messages from being
DKIM signed. If you have configured MDaemon to sign all messages then this could potentially cause some delivery problems. If you want MDaemon to sign RAW messages configured to bypass the Content Filter then you can do so by using the
x-flag=sign
option outlined below.

Additional MDaemon Features 771
Special Fields Supported by RAW
File attachment and encoding
x-flag=attach <filepath, method> [-x]
Example:
x-flag=attach <c:\utils\pkzip.exe, MIME> -x
This X-FLAG specifies the value "ATTACH" along with two parameters within the
<> characters. The first parameter is a complete path to the file which should be attached to the message. The second parameter which is separated from the first by a comma character and specifies the method of encoding that is to be used when attaching the message. MDaemon supports two values for this parameter. The method of MIME instructs the server to use the Internet standard Base64 method of message encoding. The method of ASCII instructs the server to simply import the file into the message. An optional -X parameter at the end of the string instructs the server to remove the file from disk once it has been attached.
Delivery Status Notification
x-flag=confirm_delivery
When converting a RAW message which contains this flag into RFC-2822 mail, the string is transformed to the "Return-Receipt-To: <[email protected]>" construct.
Placing Specific Header/Value Combinations into the RFC-2822 Message
header <header: value>
If you wish to place a specific header/value combination into the RFC-2822 message that will be generated from a RAW file, you will need to use the HEADER macro listed in the RAW Headers section above. For example, if you want the header "Delivered-By: [email protected]" to be placed into the RFC-
2822 message you would place this: "header <Delivered-By: [email protected]>" in the RAW message. Note that the "header" macro requires both the field and value. You can place as many "header" macros as you need into a RAW message.
DKIM Signing RAW Messages
x-flag=sign
Including this special command in a
*.raw
file will cause the RAW message to be
DKIM signed. This should only be used in RAW messages that you have configured to bypass the Content Filter (by starting their filenames with "
p
" or
"
P
"). You should not use this command in normal RAW Messages that are processed through the filter. Those messages will be signed normally.
All RAW messages that are generated by the Content Filter will use the
x-flag=sign
command automatically.

9.4 Semaphore Files
MDaemon is equipped with support for Semaphore Files, which can be used for a variety of purposes, including causing MDaemon to perform specific actions. Periodically
MDaemon will scan the
\APP\
subfolder for the existence of these files. If it finds one, the associated behavior is triggered and the semaphore file is removed. This provides for a simple mechanism that enables administrators and developers to manipulate
MDaemon without actually handling the interface. The following is a list of the semaphores and what they do:
FILENAME ACTION
ACLFIX.SEM
Runs the ACL file cleanup routine.
ADDUSER.SEM
This semaphore creates new accounts. It is used to force MDaemon to append new records to the end of the USERLIST.DAT file without causing a potentially time consuming complete rebuild of the user database.
Each line in this file must be a complete account record of the form specified in the Account Management
Functions section of the MDaemon API (see MD-
API.html
in MDaemon's \docs\API\ subfolder).
Multiple new accounts can be specified – one account record per line. MDaemon will process the file one line at a time and add each new account. You can create
ADDUSER.LCK
to lock the file while you are updating it and MDaemon will not touch ADDUSER.SEM until
ADDUSER.LCK
is deleted. To see a sample ADDUSER.SEM

file open ADDUSER.SMP in your APP directory with a text editor.
Displays in a pop-up window the contents of the semaphore file to all WorldClient users who are logged in when the file is created. It is not, however, displayed to all users immediately—it is displayed to each user individually the next time his or her browser makes a request to the WorldClient server.
Note: Unlike other semaphore files, this file is
WorldClient specific. Instead of placing it in the \app\ directory it must be placed in the \MDaemon
\WorldClient\
directory.
ALIAS.SEM
Reloads aliases data file(s).
AUTORESPEXCEPT.SEM
BATV.SEM
BAYESLEARN.SEM
BESBACKUP.SEM
Reloads the Autoresponder exception file(s).
Reloads Backscatter Protection (BATV) data file(s).
This SEM manually starts the Bayesian learning process. This is like clicking the Learn button on the
Bayesian tab of the Spam Filter. Note: this will start the Bayesian learning procedure even if you have
Bayesian learning disabled.
This SEM initiates a backup of the BlackBerry
Enterprise Server database, exactly like clicking the
Backup BlackBerry Enterprise Server database files
button at:

CLEARQUOTACOUNTS.SEM
DELUSER.SEM
The results of user quota checks are maintained in the quotacounts.dat
file. If you wish to clear the cached quota value for a user, add the user’s email address to this SEM file and then place it in the
\app\
folder. If an asterisk ( * ) is on a line by itself, the entire file will be deleted thereby invalidating all cached quota counts.
You can use this semaphore file to delete one or more user accounts. Create a text file containing the addresses of each account that you want to be deleted (one address per line), name the file
DELUSER.SEM
and then move it to MDaemon's \app\ directory. MDaemon will delete the accounts and then delete the DELUSER.SEM file. If you wish to delete an account but not delete its mail folder, append "^" to the address (e.g. [email protected]^).
DNS.SEM
DOMAINSHARING.SEM
DYNAMICSCREENUPD.SEM
EDITUSER.SEM
EXITNOW.SEM
Reloads the
90
and the Spam
Filter's DNS settings.
Reloads domain sharing data file.
Adds entries to the DynamicScreen.dat file. Place the desired entries into this file and then MDaemon will manage adding them to the the DynamicScreen.dat
file in the proper manner.
This semaphore is used to update specific user records within the USERLIST.DAT file without a potentially time consuming complete rebuild. To update any specific user records within USERLIST.DAT, create a file named
EDITUSER.SEM that includes a complete replacement record, one record per line, for any user records you wish to edit. Each record must be constructed according to the USERLIST.DAT format outlined in the
Userlist File Format knowledge base article, but it must begin with the original record's email address followed by a comma. MDaemon will process the EDITUSER.SEM
file one line at a time. You can create EDITUSER.LCK
to lock the file while you are updating it and MDaemon will not touch EDITUSER.SEM until EDITUSER.LCK is deleted. To see a sample EDITUSER.SEM file, open
EDITUSER.SMP
in your \APP\ directory with a text editor.
Shuts down MDaemon.

MDaemon will check for and remove this semaphore from the APP directory at approximately 10-20 second intervals. This file can be used by external apps to check if MDaemon is running. If this file remains in the
APP directory for more than 20 seconds, that is a good indication that MDaemon is no longer running.
9.5 Route Slips
A message file waiting in a queue typically contains within its headers all the information that is needed to get the message delivered to the proper location. There are headers stored within the file (such as the X-MDaemon-Deliver-To header) which provide MDaemon with instructions as to where and to whom the message should be delivered. Sometimes however it is necessary or useful to override this information and provide specific alternatives to where and to whom a message must be sent. Route
Slips provide just such a mechanism. A route slip is a file that provides MDaemon with very specific instructions as to where and to whom a message should be sent. If a route slip is present for a particular message file then the settings within the route slip, and not those within the .MSG file itself, control where and to whom the message is sent.
Route slips end with the extension .RTE. For example, if a message file waiting to be sent is called "MD0000.MSG," then the corresponding route slip file for this message will be called MD0000.RTE and must be located in the same folder (mail queue) as the message file.
The format of a route slip is as follows:
[RemoteHost]
DeliverTo=example.net
This section of a route slip provides MDaemon with the server to which the corresponding .MSG file is to be sent. MDaemon will always attempt a direct connection to this host attempting to route the message in as short a time as possible. Only one
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Additional MDaemon Features 779
host may be specified.
[Port]
Port=xxx
This switch specifies the port that the TCP/IP connection and delivery attempt should be made on. Port 25 is the default for SMTP email.
[LocalRcpts]
[RemoteRcpts]
These sections of the route slip allow you to specify any number of local and remote recipients who should receive a copy of the associated .MSG file. Local and remote recipient addresses must be kept separate and placed in their corresponding
[LocalRcpts]
and [RemoteRcpts] sections.
Route slips provide a good mechanism for delivering or redirecting email but they are not generally necessary. One use that MDaemon makes of route slips is in the case of
"routed" mailing list mail. When you have a mailing list that is set to route a single copy of the list message to some remote host, a route slip is employed to accomplish this. It is a very efficient method of mail delivery when you have bulk addresses to deliver mail to since only a single copy of the message is required while any number of recipients of the message can be specified. Not all remote hosts allow this sort of routing to occur however. Since it is ultimately they who will have to deliver a copy of the message file to each address, some hosts place an upper limit on the number of recipients they will allow you to specify.
9.6 MDaemon and Proxy Servers
MDaemon was purposely designed to be highly versatile. Consequently, it can be configured for use with a wide variety of network configurations and various other products, and its flexibility allows it to work well with LAN proxy servers. To configure
MDaemon to work through any proxy server, all you must do is make sure that the port settings (see
88
) you are using do not conflict with any that may be set in the proxy server itself. For example, SMTP email normally takes place on port 25. Since an
IP address can only have a single port 25, two servers cannot both listen for SMTP email at the same time on the same machine. When attempting to integrate MDaemon with a proxy
,
it is recommended that you allow MDaemon as much control over mail processing and delivery as possible. To that end, SMTP, POP, IMAP, and several other ports in the proxy may need to be disabled so that MDaemon can handle mail delivery independently.
However, should you find it necessary to channel mail through a proxy, MDaemon allows you to configure the ports which it will use to send and receive SMTP/POP/IMAP
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
780 MDaemon Messaging Server 17.0
transactions. You may need to set these ports to non-standard values in order to filter your SMTP/POP/IMAP transactions through a proxy server or firewall.
For more detailed information on configuring MDaemon to work with a proxy server, please consult the support resources available at: www.altn.com
.

10 Glossary
ACL—
Stands for

ists. ACL is an extension to the Internet Message
Access Protocol (IMAP4) that makes it possible for you to create an access list for each of your IMAP message folders, thus granting access to your folders to other users whom also have accounts on your mail server. Further, you can set permissions governing the extent to which each user has control over those folders.
For example, you can designate whether or not a user is allowed to delete messages, flag them as read or unread, copy messages to folders, create new subfolders, and so on. Only email clients that support ACL can be used to share this access and set permissions. However, if your email client doesn
' t support ACL you can still set these permissions from the MDaemon interface.
ACL is fully discussed in RFC 2086, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2086.txt
ASCII—
Pronounced as-key, ASCII is an acronym for "

nterchange". It is the worldwide standard code for representing all upper and lower-case Latin letters, numbers, and punctuation as a 7 digit binary number, with each character assigned a number from 0 to 127 (i.e. 0000000 to
1111111). For example, the ASCII code for uppercase M is 77. The majority of computers use ASCII codes to represent text, which makes it possible for them to transfer data to other computers. Most text editors and word processors are capable of storing files in ASCII format (sometimes called ASCII files). However, most data files—particularly those containing numeric data—are not stored in ASCII format.
Several larger character sets have 128 additional characters because they use 8 bits instead of 7. These extra characters are used to represent symbols and non-
English characters. The DOS operating system uses a superset of ASCII called extended ASCII or high ASCII. A standard that is closer to universal, however, is ISO
Latin 1, which is used by many operating systems and Web browsers.
ATRN—
See ETRN and ODMR below.
Attachment—
A file attached to an email message. Most email systems only support sending text files as email, therefore if the attachment is a binary file or formatted text file (e.g. a word processor document), it must first be encoded as text before it is sent and then decoded once it is received. There are a number of encoding schemes—two of the most prevalent being Multipurpose Internet Mail Extensions
(MIME) and Unix-to-Unix encode (Uuencode). For incoming messages, Alt-N
' s
MDaemon server can be configured to either leave the decoding process to the recipient
' s email client or automatically decode attachments and store them in a specific location before delivering the message to the local user.
Backbone—
A line or series of connections that form the major pathway within a network. This term is relative since the non-backbone lines in a large network might be larger than the backbone in a smaller network.
Bandwidth—
The amount of data that can be transmitted in a fixed amount of time through a network or modem connection, usually measured in bits-per-second (bps).
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Glossary 783
A full page of English text is about 16,000 bits, which a fast modem could transfer in about 1 to 2 seconds. Full-motion full-screen video would require roughly 10,000,000 bits-per-second, depending on compression.
A good illustration of bandwidth is a highway. The highway represents the connection while the cars traveling on it represent the computer data. The wider the highway (the greater the bandwidth) the more cars that will be able to travel on it.
Baud—
Baud rate is a measure of how frequently carrier signals change value on a phone line. It is a reference to the speed at which a modem transmits data. Usually, slower modems are described in terms of Baud rate while higher speed modems are described in bits per second. "Baud rate" and "bits per second" are not necessarily synonymous terms since each signal can encode more than one bit in high-speed connections.
Bit—
A single
B
inary dig
it
. It is the smallest unit of computer data; a single digit number in base-2 (i.e. 0 or 1). It is usually abbreviated with a lower case "b" as in
"bps" (bits per second). A full page of text is approximately 16,000 bits.
Bitmap—
Most pictures you see on your computer, including all the ones found on the
Internet, are bitmaps. A bitmap is a really just a map of dots (or bits) that looks like a picture as long as you
' re not to close to the screen, or have the bitmap magnified too much, to see the shape they make. Common Bitmap file types include BMP,
JPEG, GIF, PICT, PCX, and TIFF. Because bitmap images are made up of a bunch of dots, if you zoom in on a bitmap it looks blocky rather than smooth. Vector graphics
(usually created in CorelDraw, PostScript, or CAD formats) scale up much better because they are geometric shapes generated mathematically rather than simply being made of seemingly "random" dots.
Bps—
"
B
its
P
er
S
econd" is a measurement of how fast computer data can be moved from one place to another. For example, a 33.6 kbps modem can transfer 33,600 bits per second. Kilobits (1000 bits) per second and megabits (1.000,000 bits) per second are abbreviated "Kbps" and "Mbps" respectively.
Browser—
Short for "Web browser", it is an application used to display web pages. It interprets HTML code, text, hypertext links, images, JavaScript, and so on. The most widely distributed browsers are Internet Explorer and Netscape Communicator.
Byte—
A set of bits (usually eight) that represent a single character. There are 8 bits in a byte, sometimes more, depending on how the measurement is being made.
"Byte" is abbreviated with an uppercase "B".
Cache—
Pronounced like "cash". There are various types of caches, but all are used to store recently used information so that it can be accessed quickly later. For example, a web browser uses a cache to store the pages, images, URLs, and other elements of web sites that you have recently visited. When you return to a
"cached" page the browser will not have to download these elements again. Because accessing the cache on your hard disk is much faster than accessing the Internet, this significantly speeds up browsing.
MDaemon
' s IP Cache stores the IP addresses of domains to which you have recently delivered messages. This prevents MDaemon from having to lookup these addresses

784 MDaemon Messaging Server 17.0
again when delivering additional messages to the same domains. This can greatly speed up the delivery process.
CGI—C
ommon

ateway
I
nterface is a set of rules that describe how a Web Server communicates with another piece of software on the same machine, and how the other piece of software (the "CGI program") talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard. However, a CGI program is usually a small program that takes data from a web server and does something with it, like putting the content of a form into an email message, or doing something else with that data. CGI programs are often stored in a web site
' s "cgi-bin" directory and therefore appear in a URL that accesses them, but not always.
cgi-bin—
The most common name of the directory on a web server in which CGI programs are stored. The "bin" part of "cgi-bin" is short for "binary" because most programs used to be referred to as "binaries". In reality, most cgi-bin programs are text files; scripts executed by programs located elsewhere.
CIDR—

R
outing" is a new IP addressing system that replaces the older system, which was based on classes A, B, and C. CIDR IP addresses look like normal IP addresses followed by a slash and number, called the IP prefix. For example:
123.123.0.0/12
The IP prefix defines how many addresses are covered by the CIDR address, with lower numbers covering more addresses. In the above example, the IP prefix of "/12" can be used to address 4,096 former Class C addresses.
CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations.
CIDR is addressed in RFCs 1517-1519, which can be viewed at: http://www.rfc-editor.org/rfc/rfc1517.txt
http://www.rfc-editor.org/rfc/rfc1518.txt
http://www.rfc-editor.org/rfc/rfc1519.txt
Client—
A software program that is used to contact and obtain data from or send data to a
server
software program. The server is usually located on another computer, either on your local network or at some other location. Each
client
program is designed to work with one or more specific kinds of
server
programs, and each server requires a specific kind of client. A web
browser
is a specific kind of client that communicates with web
servers

Common Gateway Interface—
See CGI above.
Cookie—
In computer terminology, a
cook ie
is data sent by a web server to your web browser, which is saved and later used for various purposes when you return to the same site or go to another location on the site. When a web server receives a request from a web browser that includes a cookie, it is able to use the information the cookie contains for whatever purpose it was designed, such as customizing what

is sent back to the user, or for keeping a log of the user
' s requests. Typically, cookies are used for storing passwords, usernames, preferences, shopping cart information, and similar things related to the site to which they correspond so that the site can appear to "remember" who you are and what you
' ve done there.
Depending on your browser
' s settings, you may accept or not accept the cookies, and save them for various amounts of time. Usually cookies are set to expire after a predetermined amount of time and are saved in memory until the web browser software is closed down, at which time they may be saved to disk.
Cookies
cannot
read your hard drive. They can, however, be used to gather information about you related to your usage of their particular web sites, which would be impossible without them.
Dial-up Networking—
A component in Windows that enables you to connect your computer to a network via a modem. Unless your computer is connected to a Local
Area Network (LAN) with access to the Internet, you will need to configure Dial-Up
Networking (DUN) to dial a Point of Presence (POP) and log on to your Internet
Service Provider (ISP) before you will have Internet access. Your ISP may need to provide certain information, such as the gateway address and your computer
' s IP address.
DUN is accessed through the My Computer icon. A different dialup profile can be configured for each online service that you use. Once configured, you can copy a profile shortcut to your desktop so that all you need to do to make a connection is double-click the connection icon.
Default—
This term is used to refer to the preset value for options in computer programs. Default settings are those settings which are used when no specific setting has been designated by the user. For example, the default font setting in
Netscape Communicator is "Times". This setting will remain "Times" unless you change it to something else. Default settings are usually the value that most people will choose.
Frequently the term
default
is also used as a verb. If a custom setting won
' t work or the program lacks some needed bit of data for completing a task, it will usually
"default" to a specific setting or action.
DHCP—
An acronym for "
D
ynamic
H
ost
C
ontrol
P
rotocol". Network servers use this protocol to dynamically assign IP addresses to networked computers. A DHCP server waits for a computer to connect to it and then assigns it an IP address from a stored list.
DHCP is addressed in RFC-2131, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2131.txt
Domain Gateway—
See Gateway below.
Domain Name—
This is the unique name that identifies an Internet web site. For example, "altn.com" is the domain name of Alt-N Technologies. Each domain name contains two or more parts separated by dots; the leftmost part is the most specific while the rightmost part is the most general. Each domain name also points to the IP address of a single server, but a single server may have more than one domain
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
786 MDaemon Messaging Server 17.0
name. For example, "mail.altn.com", "alt-n.com", and "example.com" could all point to the same server as "altn.com", but "altn.com" could not point to two different servers. There are, however, methods for designating alternate servers to which clients will be directed if the main server goes down or is otherwise unavailable.
It is also common for a domain name to be registered but not be connected to an actual machine. The usual reason for this is the domain name
' s owner hasn
' t created a web site yet, or so that they can have email addresses at a certain domain without having to maintain a web site. In the latter case, there must be a real
Internet machine to handle the mail of the listed domain name.
Finally, it is common to see the term "domain name" shortened and referred to as simply "domain". The word "domain" has other meanings and can refer to other things, such as a Windows NT domain or a class of values, so you should be aware of the distinction in order to avoid confusion.
Domain Names are addressed in RFCs 1034-1035, which can be viewed at: http://www.rfc-editor.org/rfc/rfc1034.txt

DomainPOP—
Developed by Alt-N Technologies to be a part of the MDaemon server,
DomainPOP makes it possible to provide email services for an entire LAN or workgroup from a single ISP POP mailbox. In the past, unless a company
' s email server had on constant "live" connection to the Internet, the only way to provide
Internet email services to a workgroup was for each person to have their own mailbox on the company
' s ISP from which they could collect their mail. With
DomainPOP only a single mailbox is required. The ISP pools all mail for the company
' s domain name into the mailbox from which it is periodically collected by DomainPOP.
Then, DomainPOP parses the messages to determine the intended recipients of each and distributes them to the appropriate local user mailboxes. Thus email is provided for an entire network from a single dialup ISP account.
Download—
The process by which your computer retrieves or obtains data from another computer. For example, information is obtained from the Internet by
downloading
it from other computers. The reverse of this is
uploading
. If you wish to send information to another computer then you will
upload
it to them.
Driver
—A small program that communicates with a certain hardware device. Drivers contain information needed by the computer and other programs to control and recognize the device. Windows-based computers often have drivers packaged as a dynamic link library (DLL) file. Most hardware devices used with Macs do not need drivers, but when a driver is necessary it will usually come in the form of a System
Extension.
DUN—
See Dial-up Networking above.
Email—
Stands for
"
Electronic mail". This term also appears in the forms: "E-mail", "email", and "email"; all have the same meaning. Email is the transmission of text messages over communications networks. Most computer networks have some form of email system. Some email systems are confined to a single computer network, but others have gateways to other networks (which enables them to communicate with

Glossary 787
multiple locations), or to the Internet (which enables them to send email anywhere in the world).
Most email systems include some form of
email client
(also referred to as a
mail client
or just
client
) which contains a text editor and other tools for composing messages, and one or more
servers
which receive the email from the clients and route it to its appropriate destination. Typically, a message is composed using the client, passed to a server for delivery to the
email address
(or addresses) specified in the message, and then routed by the server to another server that is responsible for storing messages destined for that address. If the message
' s destination is a local address for which the original server is responsible then it may be stored on the original server rather than routed to another. Last, the recipient of the message will connect to their server and retrieve the message by using their email client. This entire process of transferring an email message from your client to its destination server usually only takes a few seconds or minutes.
Besides containing simple text, email messages may also include file
attachments
.
These attachments can be any type of file that you desire: pictures, text files, program files, other email messages, and so on. However, since most email systems only support sending text files, attachments must first be encoded (converted to a text format) before they can be sent, and then decoded when they arrive at their final destination. This process is usually done automatically by the sending and receiving mail clients.
All Internet Service Providers (ISPs) offer email. Most also support gateways so that you can exchange email with users of other email systems. Although there are many different protocols used for processing email by many different email systems, several common standards make it possible for users on virtually all systems to exchange messages.
Email Address—
A name or string of characters that identifies a specific electronic mailbox on a network to which email can be sent. Email addresses are the locations to and from which email messages are sent. Email servers need email addresses so that they can route messages to their proper destinations. Different types of networks have different formats for email addresses, but on the Internet all email addresses have the form: "[email protected]".
For example,
Email Client—
Also called a
mail client
(or just
client
), an
email client
is a software application that enables you to send, receive, and organize email. It is called a client because email systems are based on client-server architecture; a client is used to compose the email and then send it to a server, which then routes it to the recipient
' s server from which it will be retrieved by the recipient
' s client. Usually, email clients are separate software applications installed on the user
' s machine, but products such as Alt-N Technologies
'
WorldClient Server contain a built in client that is "served" to the user
' s web browser. Thus, their browser is used as the client rather than needing to install one on their machine. This greatly enhances the portability and convenience of email.
Encryption—
A security measure,
encryption
is the coding or scrambling of information
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
788 MDaemon Messaging Server 17.0
in a file so that it will only be intelligible when it has been decoded or decrypted.
Encryption is frequently used in email so that if a third party intercepted the email they would not be able to read it. The message is encrypted when it is sent and then decrypted at its final destination.
Ethernet—
The most common type of connection used in a Local Area Network (LAN).
Two of the most widely used forms of Ethernet are 10BaseT and 100BaseT. A
10BaseT Ethernet can transfer data at speeds up to 10 mbps (megabits per second) through a cable or wireless connection. A 100BaseT Ethernet transfers data at speeds up to 100 mbps. A Gigabit Ethernet can transfer data at rates up to 1000 mbps and is employed by some Apple computers.
ETRN—
An acronym meaning
E
xtended
T
U
RN
. It is an extension to SMTP that enables an SMTP server to send a request to another SMTP server to send, or "dequeue", mail that is being held for it. Because SMTP by itself cannot request mail (email is usually requested via the POP or IMAP protocols), this makes it possible for the
SMTP server making the ETRN request to cause the remote server to start an SMTP session and begin sending the stored email to the host specified in the request.
The
TURN
command used for this purpose posed a security risk because it caused the SMTP session to reverse direction and begin sending the stored mail immediately without any verification or authentication that the requesting server was actually who it claimed to be.
ETRN
starts a new SMTP session rather than reversing direction. Thus if the server making the request is a "spoofed" host, the sending server will still attempt to deliver the mail to the real host instead. There is now a proposed standard that introduces Authenticated TURN (
ATRN
), which, like
TURN
, reverses the direction of the SMTP session but requires authentication before doing so. This new standard is On-Demand Mail Relay (ODMR). Alt-N Technologies
'
MDaemon server supports both ETRN and ODMR
' s ATRN.
ETRN is addressed in RFC 1985, which can be viewed at: http://www.rfc-editor.org/rfc/rfc1985.txt
ODMR is addressed in RFC 2645, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2645.txt
FAQ—

FAQs, oftentimes all of the questions will be listed at the beginning of the document with references (or hyperlinks, in online FAQs) to the location of the question and answer in the document. FAQs are frequently used as a starting point for technical support and instructions—a great deal of time and effort can be saved if you have access to a FAQ that answers your question instead of being forced to contact technical support.

network into two or more parts, or otherwise limit access to it to certain users. For example, you might want to let everyone view the home page of a web site hosted on your network but allow only your employees to get to an "employee only" area.
Regardless of the method that you use to accomplish this—requiring a password, allowing connections from only certain IP addresses, or the like—the employee area is said to be behind a firewall.
FTP—

rotocol." It is a common and efficient method of transferring files via the Internet from one computer to another. There are specific client/server applications designed for this purpose called "FTP servers" and "FTP clients"—FileZilla, for example, is one of the most common clients. Usually FTP clients can perform quite a few other functions besides simply transferring files and are thus highly useful products. Some web browsers also contain support for File
Transfer Protocol, though sometimes for downloading only. Additionally, most FTP servers are "anonymous FTP", which means that anyone can log in to them in order to download files—usually by specifying "anonymous" as the user name and then your email address as the password. Oftentimes you can download files from anonymous FTP sites without having to log in at all—they can be retrieved by simply clicking on a link. For browsers that support FTP, usually all that needs to be done is to connect to the FTP site using "ftp://…" in its URL rather than "http://…"
FTP is addressed in RFC-959, which can be viewed at: http://www.rfc-editor.org/rfc/rfc959.txt
Gateway—
Computer hardware or software that translates data between two applications or networks with protocols that are dissimilar. "Gateway" is also used to describe any means by which access is provided from one system to another. For example, your ISP is a gateway to the Internet.
Alt-N Technologies
'
MDaemon Messaging Server can function as an email gateway for other domains through the use of its Domain Gateways feature. It acts as an intermediary, or Gateway, by collecting the domain

GIF uses indexed colors or a palette of a certain number of colors, which greatly reduces file size—especially when the image contains large areas of the same color. The reduced size enables them to be quickly transferred between systems and accounts for their popularity on the Internet. The GIF compression formula was originally developed by CompuServe and thus you will often see GIF referred to as CompuServe GIF.

Host—
Any computer on a network that acts as a server for other computers on the same network. The host machine may be running a web server, email server, or other services, and it is common for it to provide several services at once. Host is also often used in the verb form "to host". For example, a machine running an email server would be "hosting" the email.
On peer-to-peer networks it is common for machines to be both hosts and clients at the same time. For example, your machine may host your network
' s printer but also be used by you as a client to collect email and download files from another host.

' s web browser interprets and presents as a web page complete with formatted text and colors. For example, a browser receiving an HTML document containing the text "<B>Text</B>" would present the word "Text" in Bold.

Hypertext—
Any text that contains a hyperlink or jump to another document or place within the same document is called hypertext. Sometimes the text is also called a hypertext link or simply link. Hypertext can be either a word or phrase and has the link embedded in it so that clicking it will move you to the "book marked" location or cause the linked document to be displayed. Usually hypertext links are apparent because the text is underlined and a different color, but that is not required.
Sometimes hypertext will look no different than normal text, but will almost always be indicated by some sort of graphical change to your pointer when the mouse pointer is paused over it.

Internet—
The Internet was created in 1969 by the United States military, originally to be a communications network that couldn
' t be destroyed during a nuclear war. It now consists of millions of computers and networks all over the world. By design, the
Internet is decentralized—it is not controlled by any company, organization, or country. Each host (or machine) on the Internet is independent of the others and can provide whatever information or services its operators wishes to make available.
Nevertheless, most information transferred over the Internet at some point passes through "backbones", which are extremely high-bandwidth high-speed connections controlled by the largest Internet Service Providers and organizations. Most people access the Internet through an online service such as AOL or through an Internet
Service Provider (ISP) that maintains or is connected to one of these backbones.
Many people believe that the
World Wide Web
(WWW) and the Internet are the same thing, but this is not the case. The WWW is only one part of the Internet not the
Internet itself. It is the most visible and popular part, largely driven by commerce, but still only a part.
Intranet—
Simply put, an intranet is a small or private Internet used strictly within a company or organization
' s network. Although intranets vary widely from organization to organization, they may contain any of the features available on the Internet.
They may have their own email systems, file directories, web pages to be browsed, articles to be read, and so on. The primary difference between an intranet and the
Internet is that an intranet is relatively small and confined to an organization or group.
IP—
An acronym for "

P
rotocol" (e.g. as in TCP/IP). Internet protocols make it possible for data to be transferred between systems over the Internet. Regardless of each machine
' s platform or operating system, if the same Internet Protocol is used by each machine then they will be able to transfer data to each other. The term "IP" is also commonly used as a further abbreviation of the term "IP Address".
The current standard Internet Protocol is IP version 4 (IPv4).
Internet Protocol is addressed in RFC-791, which can be viewed at: http://www.rfc-editor.org/rfc/rfc791.txt
IP Address—
Occasionally called an IP Number, IP Address stands for
I
nternet
P
rotocol Address and is used to identify a particular TCP/IP network and the hosts or machines on that network. It is a 32-bit numeric address containing four numbers between 0 and 255 separated by dots (e.g. "127.0.0.1"). Within an isolated network, each computer must have a unique IP address, which can be assigned at random.
But, every computer on the Internet must have a registered IP address to avoid duplication. Each Internet IP address can be either static or dynamic. Static addresses do not change and always represent the same location or machine on the
Internet. Dynamic IP addresses change and are usually assigned by an ISP to computers that are only on the Internet temporarily—such as when a user with a dial-up account accesses the Internet. However, it is still possible for a dial-up account to have a static IP address assigned to it.
ISPs and large organizations usually attempt to acquire a range or set of IP addresses from the InterNIC Registration Service so that all clients on their network or using their service may have similar addresses. These sets are broken up into three classes: Class A, B, and C. Class A and B sets are used by very large
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
792 MDaemon Messaging Server 17.0
organizations and support 16 million and 65,000 hosts respectively. Class C sets are for smaller networks and support 255 hosts. Class A and B sets are now very difficult to get due to the shortage of available addresses; consequently most companies have to settle for multiple class C sets instead. Because of this IP address shortage, there is a new IP address protocol called Classless Inter-domain Routing (CIDR) that is gradually replacing the older system.
The current Internet Protocol standard, IPv4, is addressed in RFC-791, which can be viewed at: http://www.rfc-editor.org/rfc/rfc791.txt

Typically, users will connect to their ISP via dial-up, or some other form of connection, and then the ISP will connect them to a router, which will in turn route them to the Internet backbone.
Java—
Developed by Sun Microsystems, Java is a network-oriented computer programming language with syntax much like C/C++ but is structured around classes instead of functions. In Internet applications it is commonly used for programming applets, which are small programs embedded in web pages. These programs can be automatically downloaded and executed by a user
' s browser in order to provide a large number of functions that wouldn
' t ordinarily be possible with just HTML or other scripting languages, and without fear of viruses or harm to your computer. Because
Java is both efficient and easy to use, it is becoming popular among many software and hardware developers.
JavaScript—
Not to be confused with Java, JavaScript was developed by Netscape as a scripting language designed to extend the capabilities of HTML and create interactive web pages. It is a highly pared down and easy to use programming language, which makes it much easier to use than Java and other languages but also limits it to some degree. It spite of its limitations it is very useful for adding a number if interactive elements to web sites. For example, JavaScript is useful when you want data to be preprocessed before it is submitted to the server, or when you want your pages to respond to user interaction with links or form elements. It can also be used to control plug-ins and applets based on user choices, and to accomplish a large number of other functions. JavaScript is included within the text of HTML documents and is interpreted by web browsers in order to perform the

JPEG—
A graphics file format that is very efficient at compressing high-color and photographic images—much more so than the GIF format. While GIF is the best choice for images containing regular shapes and large areas of repeating color patterns, JPEG is much more suited to images with irregular patterns and large numbers of colors.

Kilobyte—
A kilobyte (K or KB) is a thousand bytes of computer data. Technically it is

Most LANs utilize some form of email or chat system, and share devices such as printers in order to avoid having to have a separate device for each station. When the network
' s nodes are connected together via phone lines, radio waves, or satellite links it is called a Wide Area Network (WAN) instead of LAN.
Latency—
The time it takes a data packet to move across a network connection.
While a data packet is being sent, there is "latent" time during which the sending computer waits for a confirmation that the packet has been received. In addition to bandwidth, latency is one of the factors that determine the speed of your connection.

The directory system is in a hierarchical structure consisting of the following levels: The "root" or starting directory, country, organization, organizational unit, and individual within that unit. Each LDAP entry is a collection of attributes with a unique identifier, called a distinguished name (DN). Because it is an open protocol, is efficient, and has the ability to be distributed across many servers, LDAP may eventually make it possible for virtually any application on any platform to access directory information for locating email addresses, organizations, files, and so on worldwide.

794 MDaemon Messaging Server 17.0
an email message is addressed to a
mailing list
maintained by the list server it will be automatically broadcast to the members of the list. Mailing lists typically have a single normal email address (for example, [email protected]) but that address refers to a whole list of recipients rather than to a specific person or mailbox. When someone
subscribes
to a mailing list, the list server will automatically add the address to the list and distribute future emails directed to the list to that address, or member, and all other members. When someone unsubscribes, the list server simply removes the address so that it will receive no further list messages.
Frequently the term listserv is used generically to refer to any mailing list server.
However, Listserv® is a registered trademark of L-Soft international, Inc. and is a specific program developed by Eric Thomas for BITNET in 1986. Besides other list servers, Alt-N Technologies

Logon—
a unique code or series of characters used to gain access or otherwise identify yourself to a server or machine. In most cases a password must accompany the logon in order to gain access.
There are many terms used synonymously with "logon", such as
login
,
username
,
user name
,
user ID
,
sign-in
, and others. Frequently, "logon" is also used as a verb. For example, "I am going to
logon
to the mail server". In that context, however, the more common usage (and perhaps more proper) is "I am going to
log on
to the mail server".
Mailbox—
An area in memory or on a storage device that is assigned to a specific email address and where email messages are stored. In any email system, each user has a private mailbox in which messages are stored when that user
' s mail server receives them. It is also common for the term "mailbox" to be used when referring to the leftmost portion of an email address. For example, "user01" in
"[email protected]" is the mailbox while "example.com" is the domain name.
Mailing List—
Also called email groups, a mailing list is a list or group of email addresses identified by a single email address. For example,
"[email protected]". Typically when a list server receives an email message addressed to one of its mailing lists that message will be automatically distributed to all of the list
' s members (i.e. the addresses included in the list). Alt-N Technologies

MDaemon server is equipped with an extensive suite of mailing list features that enable lists to be public or private (anyone can post or join, or only members can post or join), moderated (each message must be approved by someone before it will go to the list), sent in digest format or as individual messages, and used in a variety of other ways.
Megabyte—
Though technically 1,048,576 bytes (or 1024 kilobytes), a megabyte is more commonly rounded off and used to refer to a million bytes. Megabyte is abbreviated: "MB", as in "20 MB".

Because typically only plain text files can be transferred via email, non-text files must first be encoding into a plain text format and then decoded after reaching their destination. Thus, an email program is said to be MIME Compliant if it can both send and receive files using the
MIME standard. When a MIME-encoded message attachment is sent, generally both

Glossary 795
the type of file being sent and the method that should be used to turn it back into its original form are specified as part of the message. There are many predefined
MIME content types, such as "image/jpeg" and "text/plain". However, it is also possible to define your own MIME types.
The MIME standard is also used by web servers to identify the files they are sending to web browsers. Because web browsers support various MIME types, this enables the browser to display or output files that are not in HTML format. Further, by updating the browser
' s lists of MIME-Types and the software used for handling each type, new file formats can be readily supported.
MIME is addressed in RFCs 2045-2049, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2045.txt

Mirror—
A server (usually an FTP server) that has a copy of the same files that are on another server. Its purpose is generally to provide an alternate location from which the mirrored files can be downloaded should the original server go down or be overloaded. The term "mirror" can also refer to a configuration whereby information is written to more than one hard disk simultaneously. This is used as a redundancy measure so that if one disk fails the computer can continue to operate without losing any vital data.
Modem—
An acronym derived from

(modulates) and then transmits it to another modem where the process is reversed
(demodulates). Put simply, a modem is an analog-to-digital and digital-to-analog converter. The speed at which the data is transferred is expressed in either baudrate (e.g. 9600 baud) or kilobits per second (e.g. 28.8 kbps).
MultiPOP—

—one for external traffic and the other for internal traffic. This is mainly used as a firewall measure to help ensure network security. Your computer will appear to have a certain IP address to computers outside your LAN while your actual IP address is altogether different. Hardware or software placed "between" your network and the
Internet performs the translations between the two addresses. Using this method, it is common for multiple computers in a LAN to "share" one company IP address. Thus there is no way for someone outside your network to know your actual address and directly connect to your computer without it first being qualified or authenticated during the translation.
Network Interface Card—
A network interface card (NIC) is a computer circuit board that enables a computer to be connected to a network. NICs provide a full-time network connection whereas a modem (used by most home computers to dial-in to a network via telephone lines) usually provides only a temporary connection. Most
NICs are designed for specific types of networks and protocols, such as Ethernet or token ring and TCP/IP.

elay is a new protocol designed to enable mail servers with only an intermittent connection to a service provider, and which do not have a static IP address, to receive mail similarly to those servers that do have one and use the
ETRN
command. If the system has a static IP address, the ESMTP ETRN command can be used. However, systems with dynamic IP addresses have no widely deployed solution. ODMR solves this problem. Among other things, ODMR introduces the Authenticated TURN command (
ATRN
) which causes the flow of an SMTP session to be reversed (like the older TURN command) but with the added security of requiring that the requesting server be authenticated. This makes it possible for an
SMTP server with a dynamic IP address to connect to its ISP and have one or more host
' s email delivered to it via SMTP rather than collect it via POP or IMAP. This

helps meet the widespread demand for a low-cost solution for those companies that need to their own mail server but cannot afford a static IP address or dedicated online presence.
ODMR is addressed in RFC 2645, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2645.txt
OEM—O
riginal
E
quipment
M
anufacturer (OEM) is an often confusing and misunderstood term. An OEM is a company that uses another company
' s equipment or products in its own product that is packaged and sold under a different brand or company name. For example, HyperMegaGlobalCom, Inc. is an OEM because it purchases computer components from one or more different companies, puts them all together into a single customized product, and then sells it with
"HyperMegaGlobalCom" stamped on it. The company that sold HyperMegaGlobalCom the components might also be an OEM if they in turn got their components from someone else as well. "OEM" is an unfortunate misnomer because OEMs are not actually the original manufacturers; they are the "packagers" or "customizers". In spite of this, many people still often use the term "OEM" when referring to the actual hardware manufacturers instead of those who repackage it—and understandably so.
On the fly—
The term "on the fly" is commonly used it two different ways. First, it is often used to denote something that can be done "in a hurry" or easily while "in the middle" of performing some other task. For example, a bookkeeping product might support creating accounts "on the fly" while in the middle of entering sales figures
—"Simply stop entering figures, click button X, enter a name, and then continue entering more figures." The other way that "on the fly" is used is in referring to something that can be generated dynamically or automatically instead of manually or statically. For example, by using the information stored in a "cookie" a customized web page might be generated "on the fly" when a user returns to a web site. Rather than requiring someone to manually create a page customized to the user
' s tastes, it would be generated dynamically based upon that person
' s actions while browsing.
Original Equipment Manufacturer—
See OEM above.
Packet—
A unit of computer data sent over a network. Any time you receive data from another computer on your LAN or over the Internet it comes to your computer in the form of "packets". The original file or message is divided into these packets, transmitted, and then recombined at the destination. Each packet contains a header containing its source and destination, a block of data content, and an errorchecking code. It is also "numbered" so that it can be connected to related packets being sent. The process of sending and receiving packets is known as "packetswitching". Packets are also commonly called "datagrams".
Packet Switching—
The process of sending and receiving packets over a network or the Internet. In contrast to circuit switching (such as in an analog telephone), which sends the data in a continuous stream over a single path or circuit, packet switching transmits the data broken up into "packets", which may not necessarily take the same route to get to their destination. Further, because the data is in separate units, multiple users can send different files simultaneously over the same path.
Parameter—
A parameter is a characteristic or value. In computing, it is any value
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
798 MDaemon Messaging Server 17.0
passed to a program by a user or another program. Your name and password, a preference setting, font size, and so on are all parameters. In programming, a parameter is a value that is passed to a subroutine or function for processing.
PDF—P
ortable
D
ocument
F
ormat (PDF) is a highly compressed multi-platform file format developed by Adobe Systems Incorporated that captures document formatting, text, and images from a variety of applications. This makes it possible for the document to appear the same and print accurately on multiple computers and platforms (unlike many word processors). Viewing a PDF file requires the Adobe
Acrobat Reader, a free application distributed by Adobe Systems. There is also a plug-in for viewing PDF files with your web browser. This makes it possible to view
PDF files posted on a web site directly instead of having to download them first and then view them with a separate program.
Parse—
In linguistics, to parse is to divide language into its grammatical components that can be analyzed. For example, dividing a sentence into verbs, adjectives, nouns, and so on.
In computers, to parse is to divide a computer language statement into parts that can be made useful for the computer. A parser in a compiler is takes each program statement that a developer has written and divides it into parts that can then be used for developing further actions or for creating the instructions that form an executable program.
Alt-N Technologies
'
MDaemon server and other products often parse email messages to determine their destination or to process them through filters and other tools.
Ping—
An acronym for
P
acket
In
ternet
G
roper. It is a basic Internet program used to determine whether a specific IP address is reachable and accepting requests. It does this by sending an Internet Control Message Protocol (ICMP) Echo request and waiting for a response. "Ping" is commonly used as a verb when referring to this process. For example, "I am going to ping that server to see if it is online." "Pinging" an IP address is usually as simple as typing "ping" followed by the IP address or domain at the DOS prompt. For example "Ping 192.0.2.0."
ICMP is addressed in RFC-792 and the Echo protocol is addressed in RFC-862. These can be viewed at: http://www.rfc-editor.org/rfc/rfc792.txt
http://www.rfc-editor.org/rfc/rfc862.txt
POP—
Stands for
P
ost
O
ffice
P
rotocol. POP (also commonly appears as POP3) is the most commonly used email protocol for retrieving email from a mail server. Most email clients use the POP protocol although some also support the newer IMAP protocol as well. POP2 became a standard in the mid 1980s and required SMTP to send messages. It was replaced by the newer version, POP3, which can be used with or without SMTP. POP is sometimes used as a verb when referring to collecting your email from a server. For example, "I
' m going to POP my mailbox to get my mail."
POP3 is addressed in RFC-1939, which can be viewed at: http://www.rfc-editor.org/rfc/rfc1939.txt

Glossary 799
Port—
In TCP/IP and UDP networks and the Internet, a port is the endpoint of a logical connection and is identified by a number from 0 to 65536. Ports 0 to 1024 are reserved for use by certain privileged protocols and services. For example, web servers typically are listed on port 80, SMTP servers typically communicate on port
25, and POP servers send and receive mail on 25. Generally, only one program at a time can use, or "bind", to any given port on each machine. When browsing the
Internet, oftentimes certain servers will be running on non-default ports, which require you to specify the port in the URL after a colon. For example,
"www.example.com:3000."
Port can also be used to refer to the sockets on a computer used for connecting peripheral devices and hardware to it. For example, serial ports, parallel ports, USB ports, and so on.
Finally, port is often used to describe the process of making a program designed for a specific platform or machine function on another platform. For example, "to port a
Windows application to UNIX" or "to create a UNIX port for an application."
Post—
In Internet messaging, such as email or newsgroups, it is a single message entered into a network communications system for others to see. For example, a message displayed on a newsgroup, mailing list, or discussion board is a post. It can also be used as a verb, as in "post a message to the mailing list or on the newsgroup."
PPP—
Stands for "Point to Point Protocol." It is the Internet standard for dial-up connections. PPP is a set of rules that defines how your modem connection exchanges packets of data with other systems on the Internet.
PPP is addressed in RFC-1661, which can be viewed at: http://www.rfc-editor.org/rfc/rfc1661.txt
Protocol—
In computing, a protocol is a set of guidelines or standards by which servers and applications communicate. There are many different protocols used for many different purposes, for example, TCP/IP, SLIP, HTTP, POP3, SMTP, IMAP, FTP, and so on.
Registry—
A database used by Microsoft Windows to store configuration information about software installed on the computer. This includes things like user settings, file extension associations, desktop background, color schemes, and many others. It has the following six parts:
HKEY_User—Stores user information for each user of the system.
HKEY_Current_User—Preferences for the current user.
HKEY_Current_Configuration—Stores settings for the display and printers.
HKEY_Classes_Root—File associations and OLE information.
HKEY_Local_Machine—Hardware, operating system, and installed application settings.
HKEY_Dyn_Data—Performance data.
When programs are installed on your computer the installer usually writes some information to the registry automatically. You can manually edit the registry,
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
800 MDaemon Messaging Server 17.0
however, by using the regedit.exe program that is built in to Windows. But, you should exercise extreme caution when doing this because altering the wrong setting in the registry could cause your computer to function improperly, or not at all.
RFC—R

omments is the name of the result and the process for creating a standard on the Internet. Each new standard and protocol is proposed and published on the Internet as a “Request For Comments.” The Internet Engineering
Task Force (IETF) facilitates discussions on the new standard and eventually it is established. In spite of the fact that the standard is established and no further
“comments” are “requested,” the standard still retains the “Request for Comment” acronym along with its identifying number. For example RFC-822 (now superseded by
RFC-2822) is the official standard, or “RFC,” for email. However, those protocols that are officially adopted as “standards” do have an official standard number associated with them that is listed in the Internet Official Protocol Standards document (which itself is STD-1 and currently RFC-3700). You can find RFCs on the
Internet at many locations but the authoritative source is The RFC Editor, located at http://www.rfc-editor.org/
.
The Internet Official Protocol Standards document is located at: http://www.rfc-editor.org/rfc/std/std1.txt
RTF—R

ormat is a universal file format developed by Microsoft that is supported by nearly all word processors. In contrast to plain text format, RTF enables you to retain formatting, font information, text color, and so on. The file size of RTF files can be very large when compared to other file formats such as
Microsoft Word's format (*.doc and *.docx) and Adobe PDF.
Server—
A computer, or program, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as an SMTP server, or a machine on which the software is running. A single server
machine
could have many different server
programs
running on it concurrently. For example, your network
' s server might be running a web server, email server, FTP server, fax server, and others all at once.
SMTP—
An acronym for
S
imple
M
ail
T
ransfer
P
rotocol. It is the primary protocol used to send email on the Internet from one server to another or from a client to a server. SMTP consists of a set of rules for how a program sending mail and a program receiving mail should interact. Once a server has received email via SMTP it is usually stored there and can then be retrieved by a client via the POP, IMAP, or other protocol.
The SMTP protocol is addressed in RFC-2821, which can be viewed at: http://www.rfc-editor.org/rfc/rfc2821.txt
Spam—
Junk mail on the Internet. "Spam" is most commonly used to refer to unsolicited bulk email, although it is often used to refer to any unwanted email in general. A "spammer" will obtain hundreds, thousands, or even millions of email addresses from various sources and then "spam" the list with a message or solicitation. "Spam" can, however, be used to refer to a newsgroup or discussion board posting as well, when the posting is some unwanted or unrelated advertisement for a product or web site.
Copyright © 1996-2017. All rights reserved. Alt-N Technologies, Ltd.
Glossary 801
Spam is quickly becoming a serious problem on the Internet, tying up a great deal of time and server resources. And because spammers oftentimes use various techniques to attempt to mask the origin of the message—such as "spoofing" their addresses to appear to be someone else or attempting to relay the spam covertly through multiple mail servers—preventing it can be a challenge. Alt-N Technologies
'
MDaemon server is equipped with a number of features designed specifically to aid in fighting spam, such as: DNS Black Lists (DNS-BL), IP Shielding, IP Screening, Relay
Control, and others.
The origin of using the term "Spam" to refer to junk email is debated, but it is generally accepted that it comes from a popular Monty Python sketch in which the word "spam" is repeated over and over and periodically accompanied by Vikings singing, "Spam spam spam spam, spam spam spam spam…" However, it may simply be a disparaging comparison to the trademarked Hormel meat product of the same name—everybody gets it at one time or another, but does anyone ever really ask for it?
TCP/IP—T

P
rotocol (TCP/IP) has been described as the foundation of the Internet. It is the basic suite of communication protocols used on the Internet to connect hosts. It is the most commonly used protocol on
Local Area Networks as well. It is a two-layer system, the topmost layer being TCP, which manages the disassembling and assembling of files into packets for transmitting over the network. IP, which is the lower layer, handles the addressing of the packets so that they get to the proper destinations. TCP is addressed in the following RFC-793. IP is addressed in RFC-791. These RFCs can be found at:
TCP – http://www.rfc-editor.org/rfc/rfc793.txt
IP – http://www.rfc-editor.org/rfc/rfc791.txt
Telnet—
A command and program used to log on to Internet sites that support Telnet access. The Telnet command gets you to the logon prompt of the Telnet server. If you have an account on that server, you can access your permitted resources such as your files, email, and so on. The downside of Telnet is that it is a command line program that uses Unix commands.
The TELNET protocol is addressed in RFCs 854-855, which can be viewed at: http://www.rfc-editor.org/rfc/rfc854.txt
http://www.rfc-editor.org/rfc/rfc855.txt
Terminal—
A device that allows you to send commands to a remote computer. A terminal is a keyboard, display screen, and some simple circuitry. Oftentimes, however, personal computers are used to "emulate" terminals.

UDP is addressed in RFC-768, which can be viewed at: http://www.rfc-editor.org/rfc/rfc768.txt
Unix—
Unix, or UNIX, is an operating system created by Bell Labs in the 1960s.
Designed to be used by many users at the same time, it is the most popular operating system for servers on the Internet. There are now many different operating systems based on UNIX such as Linux, GNU, Ultrix, XENIX, and others.
URL—
Every file or server on the Internet has a
U
niform
R
esource
L
ocator (URL). It is the address that you enter into your web browser to get to that server or file. URLs cannot have spaces and always use forward slashes. They have two parts separated by "://". The first part is the protocol being used or resource being addressed (for example, http, telnet, ftp, and so on) and the second part is the
Internet address of the file or server (for example, www.altn.com or 127.0.0.1).
Uuencode—
A set of algorithms for converting files into a series of 7-bit ASCII characters for transmission over the Internet. Although it stands for Unix-to-Unix encode, it is no longer exclusive to UNIX. It has become a universal protocol used to transfer files between different platforms. It is an encoding method commonly used in email.
WAN—
A WAN, or
W
ide
A

N
etwork, is similar to a Local Area Network (LAN) but is usually spread across multiple buildings, or even cities. WANs are sometimes composed of smaller LANs that are interconnected. The Internet could be described as the biggest WAN in the world.
Zip—
Refers to a compressed or "zipped" file, usually with the "
.zip
" file extension.
"Zipping" is compressing one or more files into a single archive file in order to save space for storage or to facilitate faster transfer to another computer. To use a zip file, however, you
' ll need to unzip it first with the appropriate program such as PKZIP or WinZip. There are multiple compression/decompression utilities available—both shareware and freeware—from many sites on the Internet. Hopefully you won
' t have to unzip the utility before you can install it.
