IMail v12 Administrator Help
Web Administrator and Client
Web-based Administrator and Client
IMail Server
IMail Server (Administrator) is an Internet standards-based mail server system for
Microsoft® Windows® 2003 and Microsoft® Windows® 2008. It includes powerful administrative and anti-spam management tools all accessible via the Internet.
The Web Administrator and Console Administrator includes a series of programs that run as services: SMTP, POP3, IMAP4, LDAP3. These services can be stopped and restarted from the Service Administration page as well as from their respective pages.
IMail Server v11 and later provides local or remote access to IMail Server administration features via the Console Administrator or Web Administrator. You can administer all e-mail functions, including users, groups, services, shared calendars, contacts, tasks, notes, anti-spam and anti-virus settings (available separately).
Dictionary Attack
Options provide settings to secure your IMail Server from attacker security breaches on passwords and e-mail addresses.
Spam protection provides the ability to put the IP address of a spammer into the
Control Access list for a certain amount of time to keep the system from just reconnecting. Once the time period expires, the IP address is removed from the access list and is permitted to send mail again.
User Interface
A multi-featured main Web page allows easy administrative access to users, domains, collaboration settings for shared calendars, contacts, tasks and notes, services configuration, log viewing and management.
The IMail Console Administrator allows local administrative access to users, domains, services, log viewing and management. Collaboration settings can be accessed locally via the
Collaboration Console Administrator.
IMail Web Messaging
Web Messaging (Web mail client) lets you send and receive mail using a Web browser. You can log on to Web Messaging from a browser on any computer with a supported browser, and manage e-mail without installing e-mail client software. IMail Web Messaging directly
1
A method used to break security systems, specifically password-based security systems, in which the attacker systematically tests all possible passwords beginning with words that have a higher possibility of being used, such as names and places. The word “dictionary” refers to the attacker exhausting all of the words in a dictionary in an attempt to discover the password. Dictionary attacks are typically done with software instead of an individual manually entering each password. Also, an e-mail ...

IMail v12 Administrator Help
accesses the server to manage mail. When a user creates a mailbox in the Web client, the mailbox is created on the mail server and mail folders and messages reside on the server.
IMail Web Messaging includes an integrated Web-based client. This client replaces the current Web Client, Classic WebMail and Killer WebMail templates. This new web client sends and receives e-mail, lets you create contacts, calendars, tasks, notes and lets you organize and manage mail in folders.
If you used contacts or contact lists (distribution lists) in a previous version of Ipswitch Web
Messaging or in Microsoft Outlook with the IMail Collaboration plug-in, the contacts contact lists, calendars, tasks and notes are automatically imported into the new IMail Web
Messaging client. A new Contacts folder is created that includes contacts and contact lists.
User Interface
A unified main Web Client page allows user-friendly access to critical e-mail functions: Inbox, folders, composing, personal settings, rule and contact management, and the ability to switch between the client and the administrator pages if you have Administrator privileges.
Ipswitch Instant Messaging
Ipswitch Instant Messaging (server) provides local or remote access to Ipswitch Instant
Messaging administration features via a Web browser. You can administer all instant messaging functions, including users, public contact lists, stored conversations, and server access.
Additionally, Ipswitch Instant Messaging integrates with Microsoft® Office XP products by using Smart Tags. IIM Smart tags are person's names or e-mail addresses that are associated with an IIM contact. Microsoft Office automatically recognizes smart tags in any Office document.
IMail Collaboration
IMail Collaboration lets the people in your organization share their Outlook data, such as calendars, contacts, e-mail, tasks and notes, without the expense or expertise required by
Microsoft Exchange Server.
Optional Enhancements
IMail Anti-virus powered by Symantec™
IMail Anti-virus, available separately, can be fully integrated with IMail Server and is powered by Symantec™ CarrierScan Server, a high performance, scalable, reliable solution to protect against viruses.
IMail Anti-virus powered by BitDefender®
IMail Anti-virus, also available separately, can be fully integrated with IMail Server and is powered by SOFTWIN's BitDefender®, one of the most comprehensive virus scanners available.
IMail Anti-virus powered by Commtouch®
4
IMail v12 Administrator Help
IMail Anti-virus powered by Commtouch® has integrated Commtouch's Command
Anti-virus SDK and is now available for purchase with your IMail Server. With
Commtouch's acquisition of Command anti-virus a division of Authentium, IMail Server now offers Command Anti-virus as another optional possibility against the constant battle against spam. The Command Anti-virus engine blocks malware of all types, including worms, Trojans and spyware. Command Anti-virus has a proven track history for defending against malware for over 20 years.
Commtouch® Zero-Hour Virus Protection
Commtouch® Zero-Hour Virus Outbreak Protection provides a complementary shield to conventional AV technology, protecting in the earliest moments of malware outbreaks, and right through as each new variant emerges.
IMail Premium Anti-spam
Premium Anti-spam filtering (optional in IMail Premium), powered by Commtouch
Advanced Security Daemon (a.k.a. ctasd™) a plug-and-play email-borne spam and malware outbreak detection daemon that combines your current core messaging network infrastructure with advanced detection and classification capabilities. The daemon adds a layer of e-mail filtering to your mail delivery system in order to provide real-time classification, already in the first minutes after a new outbreak is launched.
Commtouch's GlobalView™ Mail Reputation services are used primarily to weed out spam messages and email-borne malware at the entry point before these messages enter the customer’s messaging network, thereby relieving the need for resource-consuming downstream filtering. This is accomplished by applying the most up-to-date IP reputation data to the sender IP, before the SMTP connection is accepted.
By applying GlobalView Mail Reputation services to the senders’ IP addresses before or during the SMTP session and before their messages enter the messaging network

Light use is defined by the system primarily supporting POP3 users with less than
10% of users accessing mailboxes via web mail and/or mobile devices concurrently.
Moderate use is defined as a mix of IMAP and POP3 users accessing the system with an average mailbox size less than 200 MB and less than 40% using web and/or mobile devices concurrently.

IMail v12 Administrator Help
Heavy use is defined as a mix of IMAP and POP3 users accessing the system with an average mailbox size exceeding 200 MB and more than 40% of users using web and or mobile devices concurrently.
Microsoft recommends at least 2 GB RAM for Windows 2008.
System Guidelines for Mobile Synchronization Usage
These are general guidelines and are an approximation based on in-house performance testing. There is no guarantee that the recommendations stated below will exactly match each particular clients needs. These estimates are based on moderate mobile synchronization usage. Initial mobile synchronization and complete resynchronization of data tend to have very high cpu usage, depending on the amount of data being synchronized.
System performance will seriously be degraded should a large number of initial synchronizations happen simultaneously.
It may be necessary to run the IMailSync application pool with multiple processes should there be a large number of mobile users.
Warning: IMailSync, IAdmin, and IClient should never be run in the same application pool.
Also, both IClient and IAdmin do not support multiple processes.

IMail v12 Administrator Help
Using Internet Information Services (IIS) Virtual
Directories
IMail Administrator and IMail Web Messaging (Web client) use Microsoft® Internet
Information Services (IIS) virtual directories to identify where the administrator and client
Web files are located. By default, the installation program installs the admin files in the
IAdmin virtual directory and the client files in the IClient virtual directory.
Changing IIS Virtual Directory names
If you want to change the IMail Administrator virtual directory, you need to change the following registry key entries to the new virtual directory name that you changed in the IIS
Console:
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global\WebRoot
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\Messenger Server \Settings\WebRoot
If you want to change the IMail Web Messaging virtual directory, no registry key change is required.
See the IIS help for additional information about renaming virtual directories.

Helpful Definitions
Address, Simple vs. Complete: A complete e-mail address includes the user ID and the domain name; for example, [email protected].
Authenticated users: Are users who have SMTP Authentication enabled on their e-mail client, or users who send mail from IMail Web Messaging.
By default, IMail Server forces users to authenticate, unless you select another option such as Relay Mail for Anyone or Relay Mail for Addresses in the Mail Relay Settings
(located at the Services tab > SMTP). This means that every time a user connects to the
IMail Server, he/she must enter a user ID and password.
Domain (Host) Administrator: A Domain Administrator can add, modify, or delete users or aliases (except program aliases) on the mail domain (host) he or she has permissions to. Domain Administrators also include all List Administrator permissions.
Domain Administrators cannot delete System Administrator accounts, permissions, or change other System Administrator settings. Domain Administrators will not display
System Administrator rules or file directory information.
List Administrator: A List Administrator can add, modify, or delete any list server mailing list on the mail domain(s) he or she has list admin permissions to.
27
IMail v12 Administrator Help
System Administrator: A System Administrator has full administration capabilities for all IMail permissions and options. System Administrators have both domain and list administrator permissions.
User ID: This is the user ID for the mail account. The user ID must be unique within the domain. It must be between 1 and 30 characters and cannot contain spaces.
Hyphens can be used in the user ID, but be aware that IMail Server will use the last hyphen in the user ID to delimit a mailbox name.
Example: If mail is sent to the address [email protected], IMail Server reads
"accounts" as a mailbox that belongs to mr-fred.
Windows NT registry, add a "GLOBAL IMail key of MailBoxSplitChar" and specify the new character as the first character of the string value.
File Attachment Settings
The installation program automatically configures Microsoft Internet Information Services (IIS
) 6.0 or later.
An IIS configuration file, Web.config, is installed during the installation routine. A file attribute, maxRequestLength, in the Web.config file is set to 102400 KB (100 MB). This attribute sets the maximum amount of data that can be uploaded using IIS.
Important:
maxRequestLength attribute in the
Web.config file and that you manage the Max. Outbound Message Size and Single Message Maximum Size in the Domain Properties page of the Web
Administrator. For more information, contact your e-mail administrator.
IMail Processing Order
Incoming mail addressed to a valid local address is processed in the following order.
1 SMTP Access Control. The SMTPD service checks if the connecting IP is listed in the
Access Control dialog box. If it is listed in deny access list, the connection is denied. If it is listed in the grant access list, the connection is allowed and processing continues.
2 SMTP Kill File. The SMTP service checks if the e-mail address listed in the "Mail FROM" address command to see if it is listed in the Kill List.. If the address or domain present, the SMTP service returns an error to the connecting client and does not accept the message. If no match is found, the SMTP service accepts the message.
3 Commtouch's GlobalView™ Mail Reputation Service (IP Reputation available with
IMail Premium). If enabled, fights unwanted mail at the perimeter, reducing incoming messages at the entry-point, before these messages enter the network.
28
IMail v12 Administrator Help
4 DomainKeys / DKIM Verification. If you have DomainKeys / DKIM verification enabled, you can control incoming e-mail identified as spam by signature errors.
5 Connection Filtering (Realtime Blacklists). If you have Realtime Blacklists enabled,
IMail compares the connecting IP address to the blacklists to determine if a match occurs. If a match occurs, the e-mail may be deleted (depending on the Realtime
Blacklist configuration) or an X-Header may be added and processing continues.
6 Verification Tests. If you have the verification tests enabled, they verify the "Mail
FROM" address, the HELO/EHLO domain, and perform a reverse DNS lookup. If any of these checks fail, the e-mail may be deleted (depending on the configuration) or an
X-Header may be added and processing continues.
7 Sender Policy Framework (SPF). If you have the SPF feature enabled, it provides increased capability to stop incoming e-mail from forged e-mail addresses. Using a sender authentication scheme, a domain owner requires that legitimate messages from a domain must meet certain SPF criteria. Messages that do not meet the criteria are not accepted as a legitimate e-mail message and are processed according to the SPF options selected on the SPF tab.
8 IMail Anti-virus. If you have IMail Anti-virus installed, it checks the message for infected files or code. If infected, the mail is repaired, bounced, redirected, or deleted, according to the settings on the Anti-Virus tab. If the file is not infected, content filtering attempts to identify whether the message is spam .
9 Premium Anti-spam. If you have the optional Premium Anti-spam filter installed, it provides automated spam protection in addition to the Standard Anti-spam filter included in IMail. Premium Anti-spam filter settings are applied before Standard
Anti-spam filter settings.
10 Content Filtering. If you have content filtering enabled, it determines if the message is likely to be spam. If the message is determined to be spam, it is either deleted, sent to the specified address, or an X-Header is inserted. If the message is not spam, aliases are checked.
11 Alias. IMail Server checks to see if the addressee matches an alias in the destination domain. An alias is considered to be any of the following: standard alias, group alias, program alias, or a list-server mailing list name.
If there is a match to a program, IMail Server executes the program.
If there is a match to a standard or group alias, IMail Server resolves the alias to the appropriate user ID(s), and checks the user ID.
If there is a match to a list-server mailing list name, IMail Server (a) processes the mail according to the settings for that list, and (b) checks the user IDs specified in the list settings.
If no match to any alias, IMail Server checks the user ID.
12 User ID. IMail Server determines if the user ID is valid for the destination domain. If invalid, the mail is returned to the sender. If valid, the delivery rules for a list-server mailing list are checked.
13 Delivery rules. a) Delivery Rules for the List-Server mailing list. If the message matches the rule criteria for a list, delivery follows according to the rule. If not, then the message is sent to the list server. If the message is not addressed to a list, Forwarding is checked.
29
IMail v12 Administrator Help
b) Delivery Rules for the Host. IMail Server determines if the message matches a rule for the mail host. If so, delivery follows according to that rule. If not, then rules for the user ID are checked. c) Delivery Rules for the User ID. IMail Server determines if the message matches rule criteria for the user ID. If the message matches rule criteria for a user ID, then delivery follows according to the rule. If not, then Info Manager is checked.
14 Forwarding. IMail Server determines whether an address is present in the Forward box on the General tab for this account. If so, IMail Server forwards the mail. If not, the mail is delivered to the user ID according to the established delivery rules.
15 Info Manager. IMail Server determines whether the user ID has the Info Manager enabled. If so, the automatic response is sent and the message is delivered to either the forwarding address or (if no forwarding address) to the sub-area or mailbox specified. If the Info Manager is not enabled for this user ID, the vacation setting is checked as described in the next step.
16 Vacation. IMail Server determines whether the user ID has a vacation message enabled.
If so, the vacation message is sent. If not, the message is delivered to the User ID.

Setting the E-Mail Domain Name (Official Host
Name)
Enter the complete e-mail domain name (official host name) for your IMail Server. For example, mail.domain.com.
IMail Server installation wizard attempts to automatically enter the fully qualified domain name of the machine for this field. Confirm (or enter) the official host name of the system on which you are installing IMail Server. This will be the "primary host."
The mail server host name and domain must be registered in the DNS (Domain Name System) in order for remote hosts to be able to communicate with your e-mail server. Your DNS must contain the proper entries for the host name you see here.
If you have any doubts about what to enter for the e-mail domain name, you can exit the installation program and check the DNS information for the system on which you intend to install IMail Server (the primary host).
The DNS server for the local network must appear as the first listed item on the Domain tab
menu list box. See Managing Domains (on page 129) for more information.
If you do not want to use the official host name of your server as the name of the primary mail host, you can create an alias for the primary mail host. See Setting Up an Alias for a Host
Setting Up an Alias for a Host
IMail Server accepts mail addressed to the official host name of the system on which IMail
Server is installed. You can set up an alias for the official host name so that IMail Server recognizes another name as valid. For example, if the official host name is mail.domain .com , you can receive mail addressed to [email protected], where "user" is a valid user on the host.
If you also want IMail Server to accept mail addressed to [email protected], you must enter
"domain.com" as an alias for the official host name. It can be entered in the Domain Aliases box on the Domain Properties page. To access the Domain Aliases box, see Getting to
Domain Properties.
Example:
If the mail domain name is mail.domain2.com , you can set an alias of domain2.com so that
IMail Server accepts mail addressed to [email protected] and [email protected].
Note: Host Alias requires also that the proper updates to DNS must be made to work correctly.

IMail User Database. User IDs and passwords for mail accounts are stored in a database on the IMail Server (in the registry).
External Database (ODBC Compliant). IMail uses an external database (on page 70)
to register and authenticate users. Users that you add and delete using IMail will be added to and deleted from that external database and vice versa.
System DSN
If you select External Database (on page 70), you must specify the ODBC System Data Source
Name (DSN ) for the database where the user information is stored. IMAILSECDB is the default name that the IMail ODBC link uses.
Installing SSL Keys
The IMail Server provides an SSL (Secure Sockets Layer) capability that lets SMTP , POP3 , and
IMAP connect more securely. The SSL capability relies on keys that are stored in the Windows registry.
If you have a third-party SSL certificate, click No. After installing IMail, create a
Self-Signed SSL Certificate(sslutility.exe) (on page 463)
If you do NOT have a third-party SSL certificate, but want to run the IMail web server using a "self-signed" SSL certificate, click Yes.
If you would like to read more about SSL before you make a decision, click No. You can install default keys later.

IMail v12 Administrator Help
When you configure a DSN to an SQL data source in the Microsoft Windows ODBC Data
Source Administrator, it may default to Named Pipes network library. Make sure that you set the connection type to TCP/IP in order for the external database to work correctly.
If you are currently using an external user database with an earlier (pre-v7.0) version of IMail, you must add a new set of required columns to the database table in which user information is stored. Please refer to the "External Database Changes" entry in the Release Notes section of this document for details.
If you are upgrading from IMail Server prior to version 8.1, an LDAP database conversion occurs during installation. The conversion can take a lengthy amount of time depending on the number of domains to convert. If the LDAP data is not available after the upgrade, run the LDAP Convert utility to correct the issue. In the command line utility, type: ldaper /CONVERT /Y
For more information, see the IMail Administrator Help.
If you select an install directory other than the default install directory, make sure that the IIS IUSR_<computer name> user has Administrative access to that install directory. For more information, see the Folder Rights section.
Using IIS Virtual Directories
IMail Administrator and IMail Web Messaging (Web client) use Microsoft Internet Information
Services (IIS) virtual directories to identify where the administrator and client Web files are located. By default, the installation program will install the admin files in the IAdmin virtual directory and the client files in the IClient virtual directory.
Changing IIS Virtual Directory names
If you want to change the IMail Administrator virtual directory, you need to change the following registry key entries to the new virtual directory name that you changed in the IIS
Console:
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global\WebRoot
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\Messenger Server\Settings\WebRoot
If you want to change the IMail Web Messaging virtual directory, no registry key change is required. See the IIS help for additional information about renaming virtual directories.

Using the IMail Installation Log File
The IMail installation wizard generates an install log file to help you troubleshoot software installation issues. If you selected the default installation folders, the log file is located in
C:\install-log-mm-dd-yyyy.txt.
During installation each action that occurred with respect to permissions or IIS is prefixed with "***".
Permissions are logged as follows:
*** C:\WINDOWS\system32\cacls.exe "C:\Program Files\Ipswitch\IMail" /T /E
/G IUSR_WIN2K3- SRVR:F processed dir: C:\Program Files\Ipswitch\IMail processed file: C:\Program Files\Ipswitch\IMail\ActivationStub.exe

Tip: "No

The first line is the command string used to set the permissions. If this fails, instead of seeing
"processed" lines in the log file, you will see:
*** C:\WINDOWS\system32\cacls.exe "C:\Program

No mapping between account names and security IDs was done.
IIS settings in the log file are not as detailed. If the item is not prefixed with "!!!" followed by
"Failed," then it was successful. For example, the first line in the following example is a success:
*** Disabling anonymous rights on "IIM /Status.asp".
*** Disabling anonymous rights on "IIM/StartStopServices.asp".
The following line, disabling the anonymous rights on IIM/StartStopServices.asp, failed because it is followed by an "!!! Failed.":

IMail v12 Administrator Help
Domain Aliases. Specify alternate domain names for which you want the mail domain to accept mail. Multiple aliases are separated by a space. This field is limited to 255 characters.
Administration (on page 386) page in order for the change to take effect correctly.
Example: If the mail domain name is mail.domain2.com , you can set an alias of domain2.com so that IMail Server accepts mail addressed to [email protected] and [email protected].
Note: Host Alias requires also that the proper updates to DNS must be made to work correctly.
Domain Options
Enable Microsoft Exchange ActiveSync®. (Enabled by default) Allows all enabled users for the specified domain to use ActiveSync® for synchronizing mobile devices with their web client information for e-mail, contacts, calendars, tasks and notes.
Outlook synchronization is also capable, but requires installing the IMail Collaboration
Client. Once installed Outlook will synchronize e-mail, contacts, calendars, tasks and notes with their mobile devices.
See the Mobile Synchronization Setup (on page 83) for more information.
Warning: Disabling ActiveSync® at the domain level will disable all ActiveSync® users on the specified domain, overriding the User Property setting.
Tip: For a single user to begin using Microsoft Exchange ActiveSync® there are 3 levels that require Microsoft Exchange ActiveSync® to be enabled: 1) System level, 2) Domain level
(see Domain Properties) and 3) the User level (See User Properties).
Enable Personal Information Management. Enables the use of Calendaring, Notes and Tasks for all Web Client users within the domain.
Important:

Management is selected at the mail domain level, it can be selected or cleared for each user
of the mail domain on the User Properties (on page 145) page.
Enable Virus Scanning (selected by default if available in software version).
If this option is selected, virus scanning is performed for:
the primary domain
any virtual domain (IP-less) that is bound to the primary domain
If this option is cleared, virus scanning is performed for:
any virtual domain (IP-less) that is bound to the primary domain and has the anti-virus option selected at the virtual domain level.
Enable image suppression for e-mail messages. Checked by default. This feature will suppress images for all messages. Once the link has been clicked, the images will always display when the message is selected.
Note: Once the link above the message is clicked, the images will always display when the message is selected.
Tip: When enabled at the Domain Property level, control is hidden from the users. Disabling at the Domain Property level gives user capability to control this option under their user settings.
Enable javascript removal for e-mail messages. Checked by default. This feature when checked will search all messages and disable any javascript encountered.
Tip: When enabled at the Domain Property level, control is hidden from the users. Disabling at the Domain Property level gives user capability to control this option under their user settings.
Enable Archiving. This check box allows the IMail Administrator the control of enabling/disabling specific domains for message archiving. Further user-level control can be made on the User Properties page.
Tip: The System Setting must be enabled for Mail-box Based Archiving, to allow domain-level Archiving to be enabled.
Tip: For existing domains with users requiring disabling/enabling for archiving use the
Console Administrator bulk-edit feature. Simply select necessary users on the Users page, and click edit. Any modifications made will update only selected users.

About Virtual Mail Domains (Hosts)
If you want IMail Server to receive mail for a second mail domain with its own users, you need to set up a virtual mail domain for the second domain. For example, if your mail server provides mail service for domain1.com, and you also want it to provide mail service for domain2.com, you can create a virtual mail domain for domain2.com.
There are two types of virtual mail domains:
Virtual mail domains with IP addresses (on page 142)
Virtual mail domains without IP addresses (on page 142)
must make DNS entries for your domain(s).

Setting up a Dial-up Internet Connection
IMail Server is designed to work on a 7-day, 24-hour Internet Connection, but you can also set up IMail Server to support dial-up connections. You can create a dial-up Internet connection from IMail Server to your Internet Service Provider (ISP), allowing you to receive mail from an account with your ISP.
59
IMail v12 Administrator Help
IMail Server does not perform dial-up functions or spawn off dialing commands. To start your
RAS/PPP connection to your ISP, you need to either use a scheduling program or start the connection manually.
IMail Server uses the TCP/IP transport on Windows; it does not configure the Windows TCP/IP transport. If you need to set up a RAS/PPP connection, refer to your Windows Help.
Receiving Mail from an Internet Service Provider
When you use a dial-up connection, your inbound mail from the Internet must be stored somewhere, usually with your ISP. Your ISP can store your mail in several ways. Three of the more popular ways are:
Method 1: The ISP sets up individual mail accounts on the ISP computers. This method usually uses the POP3 mail protocol to read or retrieve mail. Each user dials up the ISP and either reads or downloads mail.
Method 2: The ISP sets up individual mail accounts on the ISP computers, but the ISP forwards all mail for your users to your mail server when your dial-up connection is
up. This method uses the ISP's Internet domain name. Example. (on page 62)
Method 3: You have a registered Internet domain of your own, and you register your domain to point to the ISP computer. Your ISP stores incoming mail and forwards it to
your mail server when your dial-up connection is up. Example. (on page 63)
To register your own domain, contact your ISP. In most cases, they will do the work for you.
All you have to do is come up with a name.
If you currently use Method 1, then you must change to either Method 2 or 3 to receive mail from your ISP. IMail Server cannot log into individual mail accounts on your ISP mail server, retrieve the mail, and then parse the mail correctly.
Setting Up the Server for Dial-up Access
1 Setting up IMail Server using a dial-up connection is the same for both Methods 2 and 3, above. To do this, you need to create mail accounts for users on the IMail Server computer. For more information, see Administering IMail Users. If you use Method 2, user names must be the same on both the ISP's computer and your IMail Server computer.
2 Tell Windows about your e-mail domain name. When Windows looks up a domain name, it first searches the \winnt\system32\drivers\hosts file. If there is no match, it asks a Domain Name Server (DNS) for the IP address for the domain name.
60
IMail v12 Administrator Help
This creates a problem, as your Windows computer has a different IP address than your
ISP's computer. When IMail Server looks at the incoming mail, it looks up the domain name to which the email is addressed. If the domain name points to your ISP's computer
(your ISP's IP address), then IMail Server sends the mail back to your ISP's computer
(which it thinks is correct). Mail will be bounced back and forth until one of the computers sends the message back to the original sender.
To avoid this problem, set up the domain as a virtual host , then add the domain name to which your incoming mail is addressed -- either your ISP's (Method 2, see Example (on
page 62)), or your own (Method 3, see Example (on page 63)) on the Add New Domain
page. See Adding a New IMail Domain (on page 48), Setting Up a Virtual IMail Domain With
3 Unless you plan on maintaining a 24-hour, 7-day a week dial-up Internet connection, your ISP must spool all mail for your company. Then, have your ISP set up their computer to try to periodically send mail to the IMail Server computer. How often the
ISP attempts to send mail to your server depends on how often your dial-up connection is up. Consider the following factors in determining queue times. The first factor is the most important.
How long will your dial-up connection last (10, 20, 30 minutes)?
How often will your ISP's computer try to send the spooled mail to your computer?
How often will your computer try to send mail to the Internet?
How much mail will you receive and send when you make your dial-up connection?
For example, if the connection time will be 20 minutes, and you will have relatively light traffic (50 received and 50 sent) and relatively short messages (no attachments or large files) you could set up the queue times as follows:
Queue Time
Connection Time
Minutes
20
ISP Queue Time
IMail Server Queue Time
E-mail Quantity
15
15
50 received/50 sent (short messages)
In this example, the Connection Time is the amount of time your IMail Server is connected to the ISP's computer. This would be set in your scheduling program. The ISP Queue Time determines how often the ISP mail computer tries to send mail to the IMail Server. The IMail
Server Queue Time determines how often IMail Server tries to send mail to the ISP or Internet
(this is set up on the SMTP Options (on page 413) page).
To be sure your mail gets processed, regardless of the connection time, make the queue times less than the connection time. If you expect to receive or send greater numbers of messages, or more lengthy mail than in the example, you can either increase the connection time, or decrease both queue times.
Alternatively, you can use the ETRN command to manually retrieve mail from the ISP's mail
server. See Using ETRN to Retrieve Mail on a Dial-up Connection (on page 62).
61
IMail v12 Administrator Help
Method 2 Example
If you are using Method 2, and the computers have the following addresses and names:
ISP's IP address : 156.21.50.1
ISP's domain name: isp_are_us.com
IMail Server IP address: 156.21.50.240
IMail Server Name: my_imail_machine you would make the following entries in the \winnt\system32\drivers\hosts file:
156.21.50.240
my_imail_machine
156.21.50.240
isp_domain_name.com
You can have multiple names pointing to the same IP address. This also helps if your computer is receiving mail for multiple domains. Place each domain name in the hosts file, pointing to the IMail Server computer's IP address.

Using ETRN to Retrieve Mail on a Dial-up Connection.
There are several cases where you or your customer may want to manually retrieve mail from another mail server:
If your IMail Server is set up as an SMTP mail gateway or as a backup server for another mail server, then IMail Server stores mail for that domain until the other server is online, or, until the Tries before Return To Sender setting has elapsed. The administrator of the other server can retrieve mail manually at any time.
If your IMail Server dials in to an ISP's mail server, then the ISP's server stores mail for you. You can retrieve it manually at any time.
To retrieve mail manually:
Use a Telnet program to connect to port 25 (the SMTP port) on the other mail server, and then issue the ETRN command for their domain. For example:
ETRN @domain2.com
Or
ETRN mail.domain2.com

3 If you see keys for both the old and the new IP addresses, delete the old one. First, make sure that the "Official" value under the new IP address key shows the correct host name.
If you only see a key for the old IP address you can rename that key to the new IP address.
4 Highlight the host name key associated with that IP address, and make sure its "address" value is set to the correct (new) IP address for that host. If it is not, then change it.
5 Stop and restart all services. (on page 388)

Setting Up a Mail Gateway
You can set up IMail Server to function as a mail gateway for another mail server so that mail for the other server is sent and received through the IMail Server. Often, people set up a mail gateway because their mail server uses a dial-up connection and is not always connected to the Internet.
To set up IMail Server as a gateway for another mail server, check the following:
The other server must be running SMTP .
The mail domain (for example, domain2.com ) for which IMail Server is a gateway does not appear in IMail Server.
User accounts for the mail domain are on the other server.
The MX record for the mail domain must point to the IMail Server host. Thus, mail addressed to that domain will come to the IMail Server host. (This MX record is in the
DNS used by the other mail server.)
The IMail Server host must be able to resolve the domain name to the IP address of the other SMTP server. This is accomplished by making an entry for the domain name and IP in the hosts file (\windows\system32\drivers\etc\hosts) on the IMail Server host.
This works because IMail Server checks the hosts file and IP information before checking the DNS server. IMail Server queues the mail until it is delivered to the other server, or until the number of Tries Before Return to Sender (set up on the SMTP
Settings page) is exhausted.
If you are using any of the Relay Mail for options on the SMTP Settings Page and want to relay outgoing mail for another mail server, the address of the other server must be added by clicking the Addresses button and adding the IP address on the Relay Mail for Addresses page. For further information, see Setting IMail SMTP Options (on
Example:
64
IMail v12 Administrator Help
The following example shows how you can set up IMail Server to accept mail for a domain
(domain2.com) and forward all mail for this domain to another SMTP server. Assume the following:
Other mail domain: namedomain2.com
Host name of other SMTP server: other_SMTP_server
IP address of other SMTP server: 156.21.50.240
Host name of IMail Server: my_imail_machine
IP address of IMail Server: 156.21.50.10
When Windows looks up a domain name, it first searches the
\WINDOWS\system32\drivers\etc\hosts file. So, in the hosts file, point the domain name to the IP address of the other SMTP server:
156.21.50.240 domain2.com.
See Using ETRN to Retrieve Mail on a Dial-up Connection (on page 62) for more information.
Setting up IMail Server as a Backup Mail Spooler
You can set up IMail Server to act as a backup spooler for a customer's mail server. If the customer's computer is down, the mail for his domain will collect on your IMail Server until his is back up. The customer's mail server must have a static, unchanging IP address.
To configure this, have the customer set his computer up to log into his ISP at intervals where he can catch the queue processing interval (Times Before Return to Sender setting on the
SMTP Settings page) of your server. For example, if your retry timer is set for 30 minutes, have him connect to his ISP once every 20 minutes or so. He has to be online and ready to receive when your timer cycles.
Alternatively, he could Telnet to port 25 (the SMTP port) of your computer and issue the ETRN command with this format: etrn his_domain.com
This will dump the queued mail to his computer.
In DNS, your server will be the secondary MX for his domain (lower priority), whereas his server will be the primary MX.
You must also make an entry in your hosts file (\WINDOWS\system32\drivers\etc\hosts) which associates his IP address with his domain name. For example:
65
IMail v12 Administrator Help
his.i.p.address
his.domainname
This way, IMail Server attempts to deliver mail it receives for that domain to his computer, bypassing the MX records in DNS, which points to itself and can create a mail loop.
If you are using IMail's SMTP security to prevent spammers from using your computer as a
spam relay , add his server's IP address to the Access Control (on page 421) page.
For example, if the remote host's DNS is set up to receive mail for a primary domain, such as mail.widgets.com, and points to your IMail Server, mail.domain.com as a backup server, then the MX record for the remote host's DNS will look like this:
MX
10 mail.widgets.com
20 mail.domain.com
When mail.widgets.com is down, mail is sent to your computer mail.domain.com. To relay mail for the mail.widgets.com domain, you must specify its host name and IP address in the hosts file on your IMail Server host.

Using the IMail Database
How to get here
If you select IMail Database, user IDs and passwords for mail accounts are stored in a database in the registry on the IMail Server system, separate from either the Windows NT database or any external database.
You can also import Windows NT users into an IMail database, without having them linked to the Windows NT database.
Creating External User Database for a Mail Domain
IMail Server can use an external database to register and authenticate users on a particular mail domain. Users that you add to and delete from an IMail Server host are also added to and deleted from the external database.
Important: Remember to restart the IMail Services, after creating external database.
Before you use an external database for a mail domain, use the Windows Control Panel to make sure there is a System DSN (Data Source Name) that points to a valid database name.
See your Windows and database documentation for information on the System DSN.
Important: When you configure a DSN to an SQL data source in the Microsoft Windows
ODBC Data Source Administrator, it may default to Named Pipes network library. Make sure that you set the connection type to TCP/IP in order for the external database to work
correctly.
After you have verified the System DSN that points to the database you want to use, you can configure an external database.
Note: The external database can reside locally with the IMail Server.
Configuring an External User Database
The connection between IMail Server and an external user database is accomplished via a dynamic link library (DLL file). IMail Server includes a sample .dll file (ODBCUSER.DLL). This
DLL uses the ODBC method, but can be modified to support other external database methods. The complete source code for this DLL is provided upon request from Ipswitch.
When you configure an external user database, IMail Server creates an ODBC database that holds tables configured with the correct fields. The fields are identified in the Table Name text box. After the database is created and the ODBC system data source name is established in the ODBC Source Administration tool (located in the Windows Control Panel), you can use the database to store user authentication information and user properties. This information can be managed through IMail Administrator, including adding and deleting users.
70
IMail v12 Administrator Help
Important: When using an external database, any IMail service you run (except the Log
Server) must be set up from the Windows Control Panel Services application so the account that IMail Server runs under has access to the external database.
To create a mail domain that uses an external database:
1 In IMail Administrator, click Domain > Domain Properties.
2 In the User Database section, select External Database from the User Database type list box.
3 Click the Configure button. A domain options page appears.
External Database Implementation DLL. Enter the full path to the odbcuser.dll installed on your local server or the path of a .DLL that supports the functions:
GetUserEntry, SetUserEntry, DeleteUserEntry, AuthorizeUser, GetFirstUserEntry, and
GetNextUserEntry. (These are defined in the odbcuser.h file.)
ODBC System Data Source Name (DSN). Enter the source name for the database where the user information is stored. IMAILSECDB is the default name that the ODBC link uses.
Important: For users using SQL 7.0 or above, enter the following information after the ODBC
System Data Source Name box:
DSN_NAME;UID=<username>;PWD=<password>.
The user name and password need to be the User ID and password for the SQL database and not an
IMail Server account.
Table Name. Enter the table name within your ODBC database. Leaving "[default]" in this text box will use your domain name as the table name. All periods will be replaced with underscores.
Example:
If you use the Data Source Name IMAILSECDB and the username AUGUSTA and password
GEORGIA, the correct format of the ODBC System Data Source Name box is:
IMAILSECDB;UID=AUGUSTA;PWD=GEORGIA
Table name. Enter the database table name. If the field is blank or contains [default], the host name is used with dots replaced by underscores. The Table name cannot begin with a number.

Mobile Device Synchronization with Microsoft Exchange ActiveSync®
Note: See the Mobile Client White Paper for more detail information on mobile device setup.
IMail Server now supports Microsoft Exchange ActiveSync® for the synchronization of data between a user's mobile device and your IMail Server. Once configuration of your mobile device is complete, synchronization will allow access to your e-mail messages, calendar appointments, contact information, tasks and notes.
IMail Server currently supports the following mobile devices:
Windows Mobile® 5
Windows Mobile® 6
83
IMail v12 Administrator Help
Windows Mobile® 6.1
iPhone™ and iPod Touch™ Software version 2.2.1 or later
Google Android™ Incredible by HTC
Google Android™ Droid by Motorola
Google Android™ Droid X by Motorola
Mobile Client Requirements
Two requirements are essential for mobile device synchronization:
1 Windows Mobile® 5.0 and later are the only devices that IMail currently supports for synchronizing data to your mobile device.
2 Data Access for synchronization by either:
A data plan provided by your cellular provider or
A wireless connection with internet data access
Mobile Device Synchronization
To correctly allow users to set up their mobile devices to synchronize with your IMail Server,
Microsoft Exchange ActiveSync® must be configured to run on their mobile device. Microsoft
Exchange ActiveSync® compares the information on your device with the information on your IMail Server and updates all locations with the most recent information. Microsoft
Exchange ActiveSync® will synchronize with your IMail Server information from your E-mail,
Contacts, Calendar, Tasks and Notes through your Web Client.
Outlook Synchronization
For Outlook synchronization, the IMail Collaboration Client must be installed. The IMail
Collaboration Client is located under your
...IMail\WorkgroupShare\ClientSetup\ folder and the application name is
"ClientInternationalSetup.exe".
Once installed Outlook will synchronize E-mail, Contacts, Calendar, Tasks and Notes with the
IMail Server. For more detail information see both the IMail Collaboration Server Guide
(http://docs.ipswitch.com/_Messaging/WorkgroupShare/WGS2.3/WGSServer.pdf) and the IMail
Collaboration Client Guide
(
http://docs.ipswitch.com/_Messaging/WorkgroupShare/WGSClient.pdf
).
Web Client Synchronization
Your web client has direct access to E-mail, Contacts and Calendar data, Tasks and Notes, which does not require synchronization. Once the IMail Collaboration Client and Microsoft
Exchange ActiveSync® are correctly configured, information updated using the Web Client will synchronize with both your user's mobile devices and Outlook.
Sync Log. This log defaults to the spool directory will only exist when errors are generated.
Errors that occur with mobile synchronization will log to
"syncmmddyyyy.log".

Microsoft Exchange ActiveSync® License Summary (on page 81)
DomainKeys / DKIM
DomainKeys and DomainKeys Identified Mail (DKIM) are e-mail authentication methodologies designed to verify digitally signed e-mail on a per-domain basis. Both methods were designed for protection of e-mail identity and have assisted in the control of
"spam" and "phishing". DomainKeys and DKIM use asymmetric key cryptography to sign messages with a private key and use DNS to distribute the public key for signature verification.
DomainKeys (RFC4870 (http://tools.ietf.org/html/rfc4870)) is a precursor to DKIM (RFC4871
(http://tools.ietf.org/html/rfc4871)), though both are currently in use, DomainKeys is considered deprecated by DKIM.
See the following PDF for help in Getting Started with DomainKeys / DKIM.
DomainKeys
DomainKeys is a domain-level e-mail authentication standard that uses public/private key encryption and DNS to prove the legitimacy and contents of an e-mail message, and also verifies that the domain used in the "from" or "sender" header of a message has not been modified while in transit.
Public Key / Private Key
A public key/private key-pair is created for the sending domain. The private key is stored securely on the mail server and is used to sign all outgoing messages. The public key is stored and published in DNS as a TXT record of the domain.
When an e-mail is sent, the mail server will use the private key to digitally sign it, which is part of the message header. When the e-mail message is received, the DomainKeys signature can be verified against the public key on the domain's DNS.
For detail specifications on DomainKeys see RFC4870 (http://tools.ietf.org/html/rfc4870).
DKIM
DKIM is very similar in functionality to DomainKeys, with an enhanced standard that provides more flexibility and security. Although DKIM does not filter or identify spam, widespread use of DKIM can prevent spammers from forging the source address of their messages. If
85
IMail v12 Administrator Help
spammers are forced to show a correct source domain, then the other spam filtering techniques will work more effectively.
Some of the improvements provided by DKIM are as follows:
Multiple hashing algorithms (as opposed to just one available with DomainKeys).
Capability for one DNS text record to handle multiple domains.
Improved option for canonicalization that validates header and body separately.
Capability to delegate signing to third parties.
Capability to self-sign additional headers.
More advanced options for customization using DKIM. (e.g. Hash Algorithms, Body
Settings, Expiration)
For detail specifications on DKIM see RFC4871 (http://tools.ietf.org/html/rfc4871).

System Selector List (Signatures)
How to get here
Selectors allow a domain to have one DomainKeys selector and one DKIM selector enabled at one time. Multiple selectors are allowed in a domain to give the IMail Administrator capability to easily change from one public-key in DNS to another.
Important: Only one DomainKey selector and one DKIM selector can be enabled at one
time for a domain. Example: A DKIM selector "selector1" is enabled for domain1.com. The
IMail Administrator decides to enable "selector2" for domain1.com. "selector1" will automatically be disabled for domain1.com.
Important: After updating or creating a selector be sure to restart your SMTP and Queue
Manager services.

Realtime Blacklists (Server Level)
How to get here
Server level Realtime Blacklists are spam databases that store information about IP addresses that are known to send spam. IP addresses that have open mail relays (relays mail for anyone) are also commonly listed in blacklists, because those servers have the potential to be easily hijacked by spammers. Each blacklist compares the IP addresses from which an e-mail is sent against the spam database to look for a match. If a domain’s IP address is listed in one of the blacklists, mail from that domain should be suspected of being spam.
All blacklists must be configured and enabled at the server level before an IMail e-mail domain can use them. This lets a system administrator decide which blacklists to allow an e-mail domain to use. Only blacklists that are enabled on the Realtime Blacklists page are available for use in domain (host) level configurations.
Use Realtime Blacklists Options to add, edit and delete server blacklists. All blacklists that are currently configured for the server are displayed in the realtime blacklist. The realtime blacklist information is stored in the
"spamblkm.txt"
file located in the
"...\IMail"
top directory.
92
IMail v12 Administrator Help
Note: Realtime Blacklists must be enabled at the server level before they are made available for use at the email domain level. Realtime blacklists ar then used at the domain level (when bound to an IP address), where administrators can choose which blacklists to
enable for the host on the Connection Checks (on page 333) page.
Realtime Blacklist
Realtime Blacklist Name. Enter a name in the text box to identify a new blacklist.
This can be any name that you want, and will be used in log lines to identify the blacklist entry.
Type. Select the type of lookup that the blacklist performs from the list box.

Understanding Realtime Blacklists
What is a Realtime Blacklist?
Realtime blacklists are databases of known spammers. These databases contain IP addresses that are known to send spam. They also contain IP addresses that have open mail relays, because a spammer can easily use these systems to send out spam.
How IMail Server Uses Realtime Blacklists
IMail Server uses realtime blacklists during connection filtering. In order to fully understand how anti-spam and connection filtering work, it is necessary to understand realtime blacklists.
Connection filtering compares each message against the configured realtime blacklists to see if the IP address of the connecting server is listed. If the result is positive, the message is either deleted or an X-Header is inserted into the message.
95
IMail v12 Administrator Help
"Standard" and "Trusted" Realtime Blacklists
You can separate realtime blacklists into two categories: Standard Realtime Blacklists and
Trusted Realtime Blacklists.
A Trusted Realtime Blacklist is one that you know is updated frequently, and is more likely to be accurate. You may also identify a blacklist as trusted because you find that for your uses it produces the least number of false positives.
Warning: If a message makes a match on the Trusted Blacklist, it is automatically deleted.
A Standard Realtime Blacklist is a blacklist of which you are uncertain about its accuracy. If a message matches one of these lists, an X-Header is inserted into the message, indicating which blacklist it matched.
Configurable for Each Host
Realtime blacklists are configurable for the entire server, which enables a system administrator to decide which realtime blacklists are available to each domain. Each domain administrator is then responsible for enabling the configured blacklist for the domain. A domain cannot use a blacklist that is not configured and enabled for the server.

How Blacklists Work
Realtime blacklist databases contain a list of IP addresses that are known to send spam. They also contain IP addresses that have open mail relays, because a spammer can easily hijack these systems to send out spam. Each blacklist has different reasons for why an IP address is blacklisted. Among the more common reasons are: dialups, bulk mailers, spammers and open relays.
Categorizing IP Addresses in Separate Domains
Just as blacklists have different criteria for including IP addresses, they also have different ways of categorizing the IP addresses. Some blacklists use different domains (called query domains) to separate IP addresses based on the reason they are blacklisted. One domain will contain only IP addresses for dialup accounts, another domain will contain only IP addresses for bulk mailers. This type of categorization allows you to select the reasons for which you do
96
IMail v12 Administrator Help
not want to accept blacklisted mail, and use the domain that contains IP addresses for that reason.
Categorizing IP Addresses by a Reason Code/IP Address
Other blacklists return a reason code/IP address (i.e. 127.0.0.3) as to why an IP address is blacklisted. Although all IP addresses are listed in one domain, each will contain a reason code that explains why it is included. For example, a code of 127.0.0.3 may represent a dial-up account, and a code of 127.0.0.4 might represent a bulk mailer. The Fiveten blacklist is an example of one of these blacklists.
How to Determine Which Method a Blacklist Uses
Unfortunately, there is no standard across blacklists. One blacklist may use separate query domains, and another may use reason/IP codes. Likewise, there is no standard across the reason/IP codes that are returned. For one blacklist, 127.0.0.3 may represent dial-ups, and on another blacklist this code may represent bulk mailers. The best resources for finding out this information are the blacklists themselves. By going to their web sites, you can learn how each blacklist classifies the listed IP addresses.

Creating a rule to filter messages listed in a blacklist
Suppose you want to accept all messages whose IP addresses are listed in the FIVETEN blacklist because they are dialup addresses. You can filter the e-mail based on the X-Header that is inserted into the message and the IP/reason code that is returned from the blacklist. In the following example, 127.0.0.3 is the IP/reason code for dial up connections used by the
FIVETEN blacklist. For more information on IP/reason codes, see How Blacklists Work (on
Example of creating a rule to accept blacklists for specific reasons:
1 Make sure that all of the anti-spam features are setup with the Insert X-Header action to be taken when e-mail is determined to be spam.
2 Set up a delivery rule (Inbound Rule) at either the host or user level that will search for all messages that contain the following X-Header:
X-IMAIL-SPAM-DNSBL: (FIVETEN, +\d, 127.0.0.3)
The rule looks as follows in the Rules dialog box:
Header Contains X-IMAIL-SPAM-DNSBL:(FIVETEN, +\d,127.0.0.3)
For more information, see Setting Inbound Rules (on page 228).
Choose one of the following rule actions: Forward, Move to Mailbox, or Copy. For example, select Move to Mailbox and in the Address text box enter "Spam".
This rule searches for all messages whose IP addresses are in the FIVETEN blacklist because they are dialups and sends them to a mailbox called "Spam".
The example rule looks as follows in the rules.ima file:
H~ X-
IMAIL-SPAM-DNSBL:(FIVETEN):Spam evaluate the messages that are trapped to ensure that no legitimate mail gets caught by mistake.

Each enabled Domain level Realtime Whitelist compares the IP addresses from the e-mail sender to look for a match. If a domain’s IP address is matched, mail from that domain is trusted and allowed to bypass validations as set by the IMail Administrator.
All Realtime Whitelists must be configured and enabled at the server level before an IMail e-mail domain can be set and used. This allows the IMail System Administrator to decide which whitelists should be allowed an e-mail domain for use. Only whitelists that are enabled on the system level Realtime Whitelists page are available for use and configuration at the
Domain level Realtime Whitelists.
Use Realtime Whitelists Options to add, edit and delete server whitelists. All whitelists that are currently configured for the server are displayed in the realtime whitelist. The realtime whitelist information is stored in the under the IMail registry under the
"DNSWhitelist"
key.
Note: Realtime Whitelists must be enabled at the server level before they are made available for use at the e-mail domain level. Realtime Whitelists are then used at the domain level (when bound to an IP address), where administrators can choose which whitelists to
enable for the selected domain at the Domain > Realtime Whitelist (on page 269) page.

This user verification process can be made by setting up an External Address Verifier. The
External Address Verifier simply identifies users as valid or invalid.
The External Address Verifier is highly configurable, but currently only LDAP is supported as a verification database.

Advanced Settings
Caching Enabled. (Not set by Default) The verification process is considered an expensive cpu resource, and with a busy mail server this could at times backup the mail process. Activating Verification Caching will allow storage of verified addresses and bypass the expensive duplicate address lookups. Verified addresses will only remain in cache for the duration of the Entry Timeout Interval setting (this setting is reset each time a match is made in cache). If the cache settings for Memory Limits are left at their default zero settings then the operating system will calculate settings based on system experience and history, which usually is unlimited.
Note: It is recommended that IMail Administrators set their Memory Limits and tweak as necessary to attain the best server efficiency.
Memory Limit (MB). (Default = 0) Maximum amount of memory allowed for caching.
Once this maximum space is met, the oldest cache listings will be dropped. The default setting of zero allows the operating system to determine the limit, which effectively is unlimited.
Memory Limit (%). (Default = 0) Maximum percentage of memory allowed for caching. Once this percentage is met, the oldest cache listings will be dropped.
Entry Timeout Interval (minutes). (Default = 240) Length of time that an entry will remain in cache before being cleared out.
Note: Each time a cached entry is verified the Entry Timeout Interval is reset.
104
IMail v12 Administrator Help
Polling Interval (minutes). (Default = 2) The time interval set for cache to be poll itself. The polling process includes cleaning out expired address and also removes entries necessary to keep the memory limits within settings.
Note: Polling is an expensive process, it is recommended not to change the default setting.

Spool Manager
How to get here
The Spool directory is also known as "the queue" since it is the place where messages wait to be delivered. Messages in the queue include incoming messages, outgoing messages, and attachments, as well as error messages generated by IMail Server or other mail servers. The
Spool directory is also where the IMail Server log files (on page 429) are stored.
Files in the Spool directory are all plain text and can be viewed using Windows Notepad.
Note, however, that if you edit a D (data file) or Q file (message awaiting delivery), you could render the file incompatible with IMail Server.
To view the files in the queue, see Managing Messages in the Spool (on page 113).
Files in the Queue
Files in the queue are on the way in or out. The Number of Tries column shows the number of times IMail has attempted to deliver a message. When this number reaches the number of
Tries Before Return to Sender, which is set on the IMail SMTP Services (on page 413) page,
the message is returned to the sender as "undeliverable."
When you look at the files in the queue, you can determine what stage a message is in. This is

IMail v12 Administrator Help
File Locking
IMail employs a built-in locking system for files in the Spool Directory to eliminate concurrency problems. Locks are created by modifying the first character of a file name and creating a special file in the same directory as the locked file.
Files in the Spool Directory are only locked while critical reads or writes are being performed on the file. Old locks are removed if they are more than one hour old. This means a user may be locked out of accessing a file or a service for up to one hour as a result of a system crash during a critical time period.
It is possible to manually remove a locked file if you are positive that no process is actually accessing that file. One reason for the long time period is to allow for any time required to transmit large files over slow links. For example, the time-out should be long enough to transmit a 2+ megabyte file across a 2400 baud dial-up connection with processing delays caused by the remote end.
Attachments
Attached files also appear in the queue. For multiple attachments, the Windows Explorer naming convention is used. For example, attach.txt, attach(1).txt, attach(2).txt, and so on.
Troubleshooting
Normally, IMail Server cleans up its .tmp and attached files as part of the delivery process.
However, as with SMTP, if there is some catastrophic failure during delivery, these files may not get deleted. You can run the Spool Cleaner utility to delete old files. For more
information, see Cleaning the Spool Directory (on page 114).

Managing Spool Manager
How to get here
The mail queue, also known as the spool, is a directory that stores mail messages that are waiting for delivery. Files in the queue include incoming messages, outgoing messages, attachments, and error messages. The queue releases messages one at a time in the order that they were received. The Spool Manager provides status information about the IMail queue.

Cleaning the Spool Directory (Isplcln.exe)
Isplcln.exe is a command utility that deletes all files in the spool directory that are older than a specified number of days.
Basic Command Syntax
isplcln -n x -l y
Where x is the number of days old a non-log file has to be before it is deleted, and y is the number of days old a log file has to be before it is deleted.
Note: Note that isplcln.exe deletes all files in the spool directory based on the parameters supplied without regard to whether a file is locked or not.
Example:
114
IMail v12 Administrator Help
isplcln -n 5 -l 30
The above example deletes all non-log files that are five days old or older and deletes all log files that are thirty days old or older.
Command
-x
-y
Function
The number of days old a file must be before it is deleted.
The number of days old a log file must be before it is deleted.
File Extensions of Files in the Spool
The file extension also indicates the type of file.
.smd
and .
smp
file extensions indicate regular mail messages being processed by
SMTP.
.fwd
and .
fwp
file extensions indicate forwarded messages.
.lst
file extensions indicate messages to subscribers of a list server mailing list.
.tmp are Web Messaging.
.gse
and .
gsp
file extensions indicate error messages being returned to the senders.
These are usually generated by the server (postmaster)
Files that contain a tilde (~) in the file extension, such as
.~mp
and
.~md
, are locked files that are in process. These files also have an underscore as the first character in the file name.

Beginning Character of Files in the Spool
Files in the spool are mail messages on the way in or out of the spool. You can determine what stage a message is in by looking at the first character in the file name and by looking at the file extension.
When an e-mail message is in the spool, it is a "data file" with a file name that begins with D.
Data files have matching T, Q, and A files as they get processed.

A data file undergoing connection filtering and SPF testing; deleted when message is delivered.
A file that matches the data file while the message is inbound; when the message is fully received; the T file is renamed to a Q.
A file that matches the data file while the IMail Server attempts to deliver the message.

A Mail to Fax file.
Normally, messages are processed in a few seconds or minutes. However, if there is message delivery problem, the associated files may stay in the spool longer.
IMail does not delete the data file when a message is not deliverable; therefore, no message is ever truly lost.
If you reboot your system while a message is being received, IMail may leave behind the T
and D files. You can use the Spool Cleaner utility (on page 114) to clean up these files.

IMail v12 Administrator Help
Example: If the mail domain name is mail.domain2.com , you can set an alias of domain2.com so that IMail Server accepts mail addressed to [email protected] and [email protected].
Note: Host Alias requires also that the proper updates to DNS must be made to work correctly.
Domain Options
Enable Microsoft Exchange ActiveSync®. (Enabled by default) Allows all enabled users for the specified domain to use ActiveSync® for synchronizing mobile devices with their web client information for e-mail, contacts, calendars, tasks and notes.
Outlook synchronization is also capable, but requires installing the IMail Collaboration
Client. Once installed Outlook will synchronize e-mail, contacts, calendars, tasks and notes with their mobile devices.
See the Mobile Synchronization Setup (on page 83) for more information.
Warning: Disabling ActiveSync® at the domain level will disable all ActiveSync® users on the specified domain, overriding the User Property setting.
Tip: For a single user to begin using Microsoft Exchange ActiveSync® there are 3 levels that require Microsoft Exchange ActiveSync® to be enabled: 1) System level, 2) Domain level
(see Domain Properties) and 3) the User level (See User Properties).
Enable Personal Information Management. Enables the use of Calendaring, Notes and Tasks for all Web Client users within the domain.
Important:
"iclient.config"
can control the access of the above tools on a system wide
basis only.
Example:
To enable Calendaring, and disable Notes and Tasks. The domain level or user level
Personal Information Management must be enabled, then modify the following keys in
"iclient.config"
:
<add value="true" Key="EnableAppointments"/>
<add value="true" Key="EnableMeetingRequests"/>
<add value="false" Key="EnableNotes"/>
<add value="false" Key="EnableTasks"/>
Enable Ipswitch Instant Messaging (selected by default if available in software version). Specify whether the current mail domain will allow access to the Ipswitch
Instant Messaging service.
131
IMail v12 Administrator Help
Note: If Enable Ipswitch Instant Messaging and/or Enable Personal Information
Management is selected at the mail domain level, it can be selected or cleared for each user
of the mail domain on the User Properties (on page 145) page.
Enable Virus Scanning (selected by default if available in software version).
If this option is selected, virus scanning is performed for:
the primary domain
any virtual domain (IP-less) that is bound to the primary domain
If this option is cleared, virus scanning is performed for:
any virtual domain (IP-less) that is bound to the primary domain and has the anti-virus option selected at the virtual domain level.
Enable image suppression for e-mail messages. Checked by default. This feature will suppress images for all messages. Once the link has been clicked, the images will always display when the message is selected.
Note: Once the link above the message is clicked, the images will always display when the message is selected.
Tip: When enabled at the Domain Property level, control is hidden from the users. Disabling at the Domain Property level gives user capability to control this option under their user settings.
Enable javascript removal for e-mail messages. Checked by default. This feature when checked will search all messages and disable any javascript encountered.
Tip: When enabled at the Domain Property level, control is hidden from the users. Disabling at the Domain Property level gives user capability to control this option under their user settings.
Enable Archiving. This check box allows the IMail Administrator the control of enabling/disabling specific domains for message archiving. Further user-level control can be made on the User Properties page.
Tip: The System Setting must be enabled for Mail-box Based Archiving, to allow domain-level Archiving to be enabled.
Tip: For existing domains with users requiring disabling/enabling for archiving use the
Console Administrator bulk-edit feature. Simply select necessary users on the Users page, and click edit. Any modifications made will update only selected users.
Note: Disabling Archiving at the domain-level will ignore all user-level settings.

Creating External User Database for a Mail Domain
IMail Server can use an external database to register and authenticate users on a particular mail domain. Users that you add to and delete from an IMail Server host are also added to and deleted from the external database.
Important: Remember to restart the IMail Services, after creating external database.
Before you use an external database for a mail domain, use the Windows Control Panel to make sure there is a System DSN (Data Source Name) that points to a valid database name.
See your Windows and database documentation for information on the System DSN.
Important: When you configure a DSN to an SQL data source in the Microsoft Windows
ODBC Data Source Administrator, it may default to Named Pipes network library. Make sure that you set the connection type to TCP/IP in order for the external database to work
correctly.
136
IMail v12 Administrator Help
After you have verified the System DSN that points to the database you want to use, you can configure an external database.
Note: The external database can reside locally with the IMail Server.
Configuring an External User Database
The connection between IMail Server and an external user database is accomplished via a dynamic link library (DLL file). IMail Server includes a sample .dll file (ODBCUSER.DLL). This
DLL uses the ODBC method, but can be modified to support other external database methods. The complete source code for this DLL is provided upon request from Ipswitch.
When you configure an external user database, IMail Server creates an ODBC database that holds tables configured with the correct fields. The fields are identified in the Table Name text box. After the database is created and the ODBC system data source name is established in the ODBC Source Administration tool (located in the Windows Control Panel), you can use the database to store user authentication information and user properties. This information can be managed through IMail Administrator, including adding and deleting users.
Important: When using an external database, any IMail service you run (except the Log
Server) must be set up from the Windows Control Panel Services application so the account that IMail Server runs under has access to the external database.
To create a mail domain that uses an external database:
1 In IMail Administrator, click Domain > Domain Properties.
2 In the User Database section, select External Database from the User Database type list box.
3 Click the Configure button. A domain options page appears.
External Database Implementation DLL. Enter the full path to the odbcuser.dll installed on your local server or the path of a .DLL that supports the functions:
GetUserEntry, SetUserEntry, DeleteUserEntry, AuthorizeUser, GetFirstUserEntry, and
GetNextUserEntry. (These are defined in the odbcuser.h file.)
ODBC System Data Source Name (DSN). Enter the source name for the database where the user information is stored. IMAILSECDB is the default name that the ODBC link uses.
Important: For users using SQL 7.0 or above, enter the following information after the ODBC
System Data Source Name box:
DSN_NAME;UID=<username>;PWD=<password>.
The user name and password need to be the User ID and password for the SQL database and not an
IMail Server account.
Table Name. Enter the table name within your ODBC database. Leaving "[default]" in this text box will use your domain name as the table name. All periods will be replaced with underscores.
137
IMail v12 Administrator Help
Example:
If you use the Data Source Name IMAILSECDB and the username AUGUSTA and password
GEORGIA, the correct format of the ODBC System Data Source Name box is:
IMAILSECDB;UID=AUGUSTA;PWD=GEORGIA
Table name. Enter the database table name. If the field is blank or contains [default], the host name is used with dots replaced by underscores. The Table name cannot begin with a number.
Enable Multiple Connections to allow multiple connections from the external database to IMail Server.
Maximum Number of Connections to set the maximum number of connections from the external database to IMail Server.
Save. Click this button to save your settings.
Cancel. Click Cancel to exit without saving changes.

Adding a Virtual Host (adddomain.exe)
AddDomain.exe is a utility for adding virtual domains. It can be used to simply add a single domain, but is especially useful in a batch file to add multiple domains.
Basic Command Syntax and Example
Usage:
adddomain -h Hostname -i IPAddress -t TopDir
[-a Aliases -u IM | NT | External -x MaxMBXSize -s MaxMBXMsgs -r MaxUsers] adddomain -h Hostname -m
[-t TopDir -a Aliases -x MaxMBXSize -s MaxMBXMsgs -r MaxUsers] adddomain -h Hostname -i IPAddress -t TopDir -u External
[-e DLLFilename -o ODBC_DSN -n TableName] adddomain -h Hostname -delete adddomain -f Filename
Examples:
1 In the following example, since the -e, -o,or -n options are not specified, the external database relies on the default “values %“Imail_top dir”%odbcuser.dll , IMAILSECDB, and
[default] accordingly: adddomain -h newhost1 -i virtual -u external
2 The following command populates an external database with settings of C:\mydll.dll,
IMAILSECDB, and [default]: adddomain -h newhost2 -i virtual -u external -e C:\mydll.dll
3 The following example changes an existing host (notice the -m for modify) to use an
ODBC Data Source Name (DSN) of MyNewDSN. If the other fields of -e and -n were
140
IMail v12 Administrator Help
previously set, they will be preserved. If the other fields of -e and -n were not previously set, they will be set with the default values: adddomain -h ExistingHost -m -u external -o MyNewDSN
-n
-x
-s
-f
-a
-u
-e
-o
4 If you need to specify a DSN other than ‘IMailSecDB,’ or you need to specify a userID and password (required when setting up a DSN to connect to an SQL database), use the -o switch : adddomain -h ExistingHost -m -u external -o IMailSecDB;UID=MyUser;
PWD=MyPassword
5 The following example shows how to add a new virtual host (or virtual host with an IP ) using an external database: adddomain -u external -t C:\IMail\newdomain_com -i virtual
-o IMailSecDB;UID=sqluser;PWD=sqlpassword -n table_name
6 Adddomain.exe supports the following command line options:
Command Function
-h
-i
-t
Fully qualified host name; must match the IMail official host name
IP address or virtual IP address for an IP-less host
Path (full or relative) to the top directory for the domain
-m Command to modify existing settings instead of creating new ones
Alias list for a host
User data base to use (IMail, NT, or external)
Path to external database implementation DLL
External database ODBC system Data Source Name (DSN )
External database table name
Default max mailbox size (in kbytes).
Default max number of messages for mailbox.
Path to the file containing the settings to modify
-r Maximum number of users allowed on this host.
-delete Removes the virtual host.
141
IMail v12 Administrator Help
Note: AddDomain.exe does not warn when assigning already claimed IP addresses to new hosts. Assigning an already used IP address to another host will orphan the original host without warning.
Setting the IP Address for a Virtual Host
If you use a virtual IMail domain with an IP Address , all capabilities of regular IMail Server mail domains are available to virtual domains with IP addresses. The only limitations of virtual
IMail domains with IP addresses are:
Each virtual domain requires its own unique IP address.
In Microsoft Windows, this requires the extra step of adding an IP address in the Windows NT
TCP/IP configuration in the Control Panel (Network Connections > Local Area Connections
> Properties > TCP/IP Protocol > Advanced). proper DNS entries for your mail domain(s). If you use a virtual IP address, the MX record (in
DNS) for the mail domain must point to a real IP address.
Setting Up a Virtual Host Without an IP Address
If you use a virtual IMail domain without an IP Address, IMail Server assigns the virtual IP address. This method lets you have a virtual mail domain without an IP address. After you set up a virtual IMail domain, use an MX record in your DNS to point the virtual mail domain to a real IP address.
Important: Whether you use a real IP address or a virtual IP address, you need to make the proper DNS entries for your mail mail domain(s). If you use a virtual IP address, the MX record
(in DNS) for the mail domain must point to a real IP address.
There are several limitations to a virtual IMail domain without an IP address:
Users must log in to mail accounts on the mail domain by specifying their User ID as userid@virtualhost, where userid
is the User ID and virtualhost is the host name. This associates the IMail Server with the correct virtual IMail domain.
LDAP server does not work with virtual IMail domains that do not use an IP address.
When to use IP-less Virtual IMail Domains
Virtual IMail domains without IP addresses are recommended when you have a shortage of IP addresses or when you want to forward all mail for a domain to a user at another domain.
Example:
Your primary domain is called abracadabra.com. You want all mail that is sent to merlin.com to be forwarded to [email protected]. To accomplish this:
142
IMail v12 Administrator Help
1 Set up a virtual IMail domain without an IP address for merlin.com and do not create any users for merlin.com.
2 Set up a nobody alias (on page 211) for merlin.com pointing to a user ID on
abracadabra.com. All mail to any user at merlin.com is sent to the specified user at abracadabra.com (in this case, [email protected]).

<enable_usagebar>false</enable_usagebar>
2 If the preferences.config file is not present,it is possible that it may not be there if the user has not updated their preferences since the latest version of the Web client was installed. If it is not there, simply add the following text. If it is there, then change that node so that it appears as follows:
<enable_usagebar>false</enable_usagebar>
Note: If the above node is not present, it must be added at any ending node: e.g. </node>, but do not add at the beginning or the end, as this will cause XML errors.

Vacation Message
How to get here
Note: Vacation Message can handle all foreign characters for display in the Web Admin.
You can create a vacation message for each e-mail user account. When the vacation message is enabled, IMail Server sends an automated vacation message to each email address the user receives mail from. The vacation message is stored in the vacation.ima file in the user's IMail
Server home directory.
Note: Vacation Message can also be enabled and disabled within the user's Web Client.
Domain Name (OHN). The current domain name used to address mail to the users on the mail domain is displayed.
User ID. Displays the selected user ID (user name) for the e-mail account.
Enable Vacation. Check box to enable or disable the Vacation Message text box. Disabling the vacation message will clear the "vacation snt" file.
Vacation Message. Text box when enabled, allows a vacation message to respond to all new mail messages received. The vacation response will only be sent once to each unique e-mail address.
Save. Click this button to save your settings.
To create a vacation message:
1 Select Enable Vacation.
2 In the Vacation Message text box, enter the reply message you want to send while the user is away. The vacation message is sent one time to each e-mail address from whom the recipient receives mail. IMail Server saves the message sender's e-mail address in a file (vacation.snt). This file provides the user with a list of users that sent e-mail while away and also keeps track of the senders so the vacation message is only sent one time to each sender.

Auto Responder
How to get here
Note: Previously called Information Manager, was changed to match the Web Client title of
Auto Responder for clarity.
The Auto Responder can automatically handle routine e-mail inquiries for common information about your company. For example, you might want to respond to general inquiries with an acknowledgment that the inquiry was received plus a promise to follow up.
Using the Auto Responder for a Single Automated Response
To use the Auto Responder, you first need to set up a special user account whose user ID is
Info. This mail account does not belong to a specific user, but accepts mail addressed to
. When someone sends mail to the Info account, she receives a prepared response such as:
"This is an automated response from General Sales. You will receive a personal response by e-mail from one of our staff within two business days."
Subdividing the Auto Responder Account
You can subdivide an Auto Responder account into more specific sub-areas that can automatically send more detailed information in response to inquiries.
180
IMail v12 Administrator Help
Example:
You can have an automated response that lists products, prices, and ordering information; another automated response that describes the classes you offer the general public; and a third automated response that sends out company news.
To divide the Auto Responder account into more specialized responses, you create sub-areas of account (such as Sales, Classes, or News) from which the sender can obtain more specific information. Then, when someone sends mail to the [email protected] account, IMail Server returns a prepared response that describes the Auto Responder account sub-areas such as:
"Thank you for contacting Ipswitch. For information about our products, please send email to
[email protected]. For information about our classes, send mail to
[email protected]. For the latest Ipswitch news, send email to
The sender could then send a message to [email protected] and receive a special message related to sales or the sender could send a message to [email protected] and receive a message about classes.
There is no limit to the number of sub-areas you can use with the Auto Responder. Sub-areas take up no disk space since messages addressed to them merely activate an automated response. In other words, mail addressed to sub-areas is not stored anywhere, unless you specify that it be saved.

DomainKeys / DKIM
How to get here
Domain Signing Options (Selectors) (on page 185)
DomainKeys/DKIM Verification Settings (on page 193)
Add Selector Wizard (on page 200)
DomainKeys and DomainKeys Identified Mail (DKIM) are e-mail authentication methodologies designed to verify digitally signed e-mail on a per-domain basis. Both methods were designed for protection of e-mail identity and have assisted in the control of
"spam" and "phishing". DomainKeys and DKIM use asymmetric key cryptography to sign messages with a private key and use DNS to distribute the public key for signature verification.
DomainKeys (RFC4870 (http://tools.ietf.org/html/rfc4870)) is a precursor to DKIM (RFC4871
(http://tools.ietf.org/html/rfc4871)), though both are currently in use, DomainKeys is considered deprecated by DKIM.
See the following PDF for help in Getting Started with DomainKeys / DKIM.
DomainKeys
DomainKeys is a domain-level e-mail authentication standard that uses public/private key encryption and DNS to prove the legitimacy and contents of an e-mail message, and also verifies that the domain used in the "from" or "sender" header of a message has not been modified while in transit.
Public Key / Private Key
A public key/private key-pair is created for the sending domain. The private key is stored securely on the mail server and is used to sign all outgoing messages. The public key is stored and published in DNS as a TXT record of the domain.
When an e-mail is sent, the mail server will use the private key to digitally sign it, which is part of the message header. When the e-mail message is received, the DomainKeys signature can be verified against the public key on the domain's DNS.
184
IMail v12 Administrator Help
For detail specifications on DomainKeys see RFC4870 (http://tools.ietf.org/html/rfc4870).
DKIM
DKIM is very similar in functionality to DomainKeys, with an enhanced standard that provides more flexibility and security. Although DKIM does not filter or identify spam, widespread use of DKIM can prevent spammers from forging the source address of their messages. If spammers are forced to show a correct source domain, then the other spam filtering techniques will work more effectively.
Some of the improvements provided by DKIM are as follows:
Multiple hashing algorithms (as opposed to just one available with DomainKeys).
Capability for one DNS text record to handle multiple domains.
Improved option for canonicalization that validates header and body separately.
Capability to delegate signing to third parties.
Capability to self-sign additional headers.
More advanced options for customization using DKIM. (e.g. Hash Algorithms, Body
Settings, Expiration)
For detail specifications on DKIM see RFC4871 (http://tools.ietf.org/html/rfc4871).

Domain Selector List (Signatures)
How to get here
Selectors allow a domain to have one DomainKeys selector and one DKIM selector enabled at one time. Multiple selectors are allowed in a domain to give the IMail Administrator capability to easily change from one public-key in DNS to another.
Important: Only one DomainKey selector and one DKIM selector can be enabled at one
time for a domain. Example: A DKIM selector "selector1" is enabled for domain1.com. The
IMail Administrator decides to enable "selector2" for domain1.com. "selector1" will automatically be disabled for domain1.com.
Important: After updating or creating a selector be sure to restart your SMTP and Queue
Manager services.

DomainKeys / DKIM Wizard
How to get here
The DomainKeys / DKIM Wizard was designed to allow and IMail Administrator to quickly setup the necessary items for DomainKeys / DKIM.
Step 1
DomainKeys or DKIM
DomainKeys and DKIM allow messages to be cryptographically signed, which allows receiving servers to verify the source and contents of messages. Both specifications are similar, however, DKIM handles e-mail routing better than DomainKeys and is considered to be the preferred method of signing messages.
Choose the selector type:
DomainKeys. Uses Message Algorithm for Preparation Signing.
DKIM. Uses Header and Body Algorithm for Preparation Signing.
Requires a selector Name to allow identification within the IMail Administration.
Enter the DNS Text Record that will associate the selector in DNS. This text name allows any text string that is a legal DNS domain name.
Example: DNS Text Record set to MyDNSName will be named
"MyDNSName_domainkey.domainname.com"
Description is optional and is limited to 1024 characters.
Step 2
200
IMail v12 Administrator Help
Choosing your Algorithm:
The simple and relaxed header and body algorithms prepare the e-mail before signing occurs. This is known as canonicalization and does not affect the message that is actually sent in any way. These algorithms attempt to handle cases where normal transformations that occur to a message as it is sent will cause a signature to be verified incorrectly. The 'simple'
Canonicalization algorithm tolerates almost no modification of the message, while the
'relaxed' canonicalization algorithm allows some typical transformations to occur without breaking the signature (such as modifying whitespace and folding whitespace in the message and its headers). The relaxed canonicalization algorithm is recommended unless it is critical that a message not be modified in any way during transit to a receiving mail server.
Header Algorithm (DKIM only). DKIM uses both the Header and Body Algorithm as the specified canonicalization method.
Simple. This algorithm is designed to be the least tolerant. Each header is unfolded per RFC2822 and is converted to lowercase.
Relaxed. (Set by default) This algorithm tolerates common modifications such as white-space replacement and header line re-wrapping.
Body Algorithm (DKIM only).
Simple. This algorithm is designed to be the least tolerant.
Relaxed. (Set by default) This algorithm tolerates common modifications such as white-space replacement and header line re-wrapping.
Message Algorithm (DomainKeys only). DomainKeys uses the Message Algorithm as the specified canonicalization method.
Simple. Allows toleration of almost no modification.
No Folding Whitespace (nofws). (Set by Default) Allows common modifications such as white-space replacement and header line re-wrapping.
Step 3
Assigning Domains
Please choose which domains are allowed to use this selector for signing. Domains added to the list on the right are able to use this selector for its users.
By default, when run at the domain level, only the selected domain be selected, otherwise it will be up to the IMail Administrator to select which domains will be assigned.
This step gives you the capability to also add any existing domains to the selector.
Any domains that are in the "Available Domains" box can be assigned the new selector being created.
Note: The selector will not be enabled until the DNS Test is valid. Should the DNS Test fail, all domains set for this selector will be disabled. It will be up to the IMail Administrator to enable the selectors after the DNS has been corrected.
Step 4 (DKIM Selectors Only)
201
IMail v12 Administrator Help
One or Multiple DNS Text Records
This step will only appear when creating a DKIM selector and multiple domains have been assigned to the selector. DKIM has the capability to have all domains point to one specified domain for the DNS record. This is the simplest and recommended way of setting up DKIM. If you wish, however, you can choose to enter a DNS record for every domain by selecting the second option in the drop down list.
By default this feature is selected. Should you want to create a DNS record for each domain, select the second option "All domains use their own DNS records".
Note: DomainKeys is not as flexible as DKIM and requires a DNS text record for each domain, per the RFC.
Step 5
Private Key and DNS Text Record
This page has generated a private key that must be inserted into the DNS text record that is identified under the text box.
Example:
DnsTextRecord_domainkey.domain.name.com
Generate a matching DNS text record for each item listed on the wizard page.
If you do not have access to your DNS records, contact your DNS administrator to add these records. Please note, that it is recommended that you continue to the next screen and save this selector if the process of adding the DNS records will take more than a few minutes.
Tip: Remember to check for the "p=" in front of the key
Step 6
DNS Test and Selector Status
At this point the DNS text record must exist to be tested for validity. If the DNS record has not yet been created, it is recommended to click "Done" to save the selector.
Warning: Click "Done" now, as the IMail Server will eventually time out and your selector will be lost.
Also, if the DNS text record has not been created, it is recommended to disable the selector.
After the DNS text record has been created, it can be tested by editing the selector.
The DNS Test button is located under the Domains list using the new selector.
The DNS Test button will display "successful" for each domain. A link to assist with
DNS problems will display for domains that "failed".

Domain Trailer
How to get here
The Domain Trailer page allows the System Administrator to maintain separate trailer messages at the domain level. This will allow all outgoing messages to append a domain trailer message to outgoing message for a specific domain (This does not include locally sent messages within the server). By default when a domain is created it will be set to use the
System Trailer.
Tip: To access the System trailer, see System > System Trailer (on page 78).
Two text files will be created, one for plain text, and one for html. The text file names are
"DomainTrailer.txt"
and
"DomainTrailer.html"
located in the
"\IMail\DomainName"
directory.
Note: Messages sent locally within the IMail Server do NOT include the trailer.
Depending on the type message being sent, the IMail Server will append the trailer as follows:
A "Plain Text" message will append the
"DomainTrailer.txt"
text file.
An HTML message will append the
"DomainTrailer.html"
text file.
Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.

Alias Administration
How to get here
An e-mail alias is an alternative for a user's e-mail address, a group of user's e-mail addresses, or an application that performs additional e-mail functions. An e-mail alias looks like an e-mail address, but it is a name defined within an e-mail domain to represent a logon name.
Therefore more than one e-mail alias may refer to a POP3 account. IMail Server supports the following alias types:
Standard alias (on page 210)
To comply with the Internet mail RFC specifications, you must have a postmaster alias so
Internet mail users can send mail to postmaster@your_domain_name. IMail Server
207
IMail v12 Administrator Help
automatically sets up the postmaster alias to point to the root
account. You can change the postmaster alias to point to a different mail account.
You can create aliases one at a time in the IMail Administrator or you can add a batch of aliases at one time. For more information about adding aliases with a batch file, see Adding an
Alias (addalias.exe) (on page 212). If you plan to add a group alias, you can prepare a text file
before you add the group alias. Enter all the mail addresses you want to include in the group into a text file; enter one address per line followed by a carriage return. Place the file in the host directory.
If you plan to create a program alias, copy the application to the IMail Server system. You can also use a
.bat
file to store the commands you want to use. (In this case, the program alias will point to the .bat file, making it easy to edit the
.bat
file at any time without having to change the program alias.)
A- Z, a-z, 0-9, - (hyphen), and _ (underscore). The name cannot contain spaces and must be unique for this mail host.
Aliases display as follows:

Command Function
-a aliasname Adds an alias if the alias does not exist. aliasname is the name of the alias you want to add. Only one alias may be added in a single command line.
-cX Specifies an alternate delimiting character, which replaces the default delimiter (the equal sign). Spaces are not allowed. (Using -c in a text file affects all lines in the file.)
-d aliasname Deletes an alias that already exists, where aliasname is the alias you want to delete.
Only one alias may be deleted in a single command line.
-f filename You can put multiple commands into a text file for one execution of Addalias. Use -f to specify the name of the text file containing the Addalias commands. (All the above commands are valid for the text file, but note that -h and -c persist across multiple lines of input.)
-h hostname Specifies the virtual domain for the alias. The primary domain is used if no e-mail domain is specified. (Using -h in a text file affects all lines in the file.)
-i groupname Imports an NT group as a group alias if the alias does not already exist. groupname is the group that you want to import. Only one alias can be added in a single command line.
-l Lists current aliases. This argument may not be used in a text file.
-m aliasname Modifies or adds an alias even if the alias exists. aliasname is the alias you want to modify. Only one alias may be modified in a single command line.

List Administration
How to get here
List-server mailing lists or "automated" mailing lists, are used widely on the Internet as a means of sharing information about a topic. The IMail list server lets you set up list-server mailing lists that receive mail and resend mail to all the users on the mailing list.
The list server can also archive messages and send them periodically (on page 235) as a single
message or "digest."
Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.
Search Box. Typing will automatically begin narrowing the list. The search assumes a wildcard automatically after the characters entered.
Note: Column Titles when clicked will sort the list for the current session only. Refreshing the page will reset the original sort.

Default List Settings
List Owner's E-mail Address. Enter the full e-mail address of the list default list owner. This is the mail account that receives all messages (such as Subscribe and
Unsubscribe requests) to the list. It is also the account from which help messages are sent and to which error messages are sent.
Note: The List Owner e-mail address does not have access to the List Administration pages unless the e-mail address is same as the local list administrator or has List Administrator
permissions for the local domain. See the User Properties (on page 145) page.
Administrator's Local User ID. Enter the default list administrator user ID. Enter only a User ID (do not add the full e-mail address) that resides on the local domain for the
list administrator. This will allow local list administration (on page 241) permissions for
only the specified list.
Important: To allow permissions for all lists, the User ID can be given List Administrator
rights See the User Properties (on page 145) page.
account can be set up to be the list owner in order to hide the identity of the list administrator or to give the impression of more people being involved in the list management.
Maximum Message Size (bytes). Enter the maximum size of a message that can be sent to the list. Enter 0 if you want the size to be unlimited.
Number of Recipients Per Message. Enter the number of recipients each SMTP process will send to. To calculate this number, divide the expected number of subscribers by 25. The result is the number of recipients per message.
Example:
217
IMail v12 Administrator Help
You want to send an e-mail to a list of 5,000 subscribers. Divide 5,000 (number of subscribers) by 25 (number of processes) and the result is 200 (recipients per message). So you would have 25 processes that each handle 200 recipients.
If you increase this number, you may need to also increase the number of SMTP processes.
For more information about how to change the default number of SMTP processes for IMail
Server, see SMTP Settings Advanced Options (on page 413).

Types of List Server Mailing Lists
There are three kinds of basic lists (determined by the setting of Allow Postings By on the
List Security page):
Anyone (on page 219) (open list). Anyone can post a message to the list; the individual
that posts to the list does not have to be a list subscriber.
Subscribers (on page 219). Only a list subscriber can post a message to the list.
Moderated (on page 219). Only a list owner (on page 242) can post a message to the
list. Moderator is used when you want the list owner to review all messages before they are posted to the list.
You can further restrict the message posts with:
A password requirement.
A posters' list.
Those who send mail to a list restricted by a password and/or posters' list will have their mail returned with a "Restricted Post" message. the moderator can give those few the appropriate password. However, if there are more than a few individuals who are permitted to post to the list, it may be more efficient to use a posters list.

Moderated Lists
The characteristics of a moderated list are:
The moderator can post by addressing mail in the form of [email protected].
Only the moderator (list owner) can post a message to the list if Use Password and
Enable Posters List are cleared.
If Use Password is selected, the moderator must use a password in order to post to the list. This prevents others from "impersonating" the moderator by using the moderator’s mailing address.
If Enable Posters' List is selected, users in the posters' list (on page 238) can post
directly to the list and the moderator does not receive their mail. The moderator receives mail only from the addresses that are not in the posters' list.
If both Use Password and Enable Posters' List are selected, the moderator receives mail only from those not in the posters' list and the moderator must enter a password in order to post to the list.

The characteristics of an open list are:
Anyone can post to the list by addressing mail in the form of [email protected] .
If Use Password is turned on in the List Security page, all list posters must enter a password to post to the list.
The Enable Posters List option does not affect open lists. If this option is selected, anyone will still be able to post to the list whether they are in the posters list or not.

Subscriber Lists
The characteristics of a subscriber list are:
219
IMail v12 Administrator Help
The list is made up of subscribers. An individual becomes a subscriber by sending a message addressed to the IMail list server ( [email protected] where domain.com represents the mail domain). In the body of the message, the intended subscriber enters the subscribe command and list name.
Subscribers post a message by addressing mail in the form of [email protected] .
If Use Password is selected in the List Security page, users must enter a password to post a message.
If Enable Posters List is turned on, only subscribers and users in the posters list can post.
For a subscribers only list, users who are in the posters list can post messages to the list without being a subscriber. In this case, the user will not receive any list postings.
If both Use Password and Enable Posters List are turned on, a subscriber must enter a password to post. Users in the posters list must enter a password as well.

Inbound / Outbound Rules
Delivery rules are used to direct mail based on the contents of the To, From, Sender,
Subject, message Header, or the message Body fields.
Rules are helpful in filtering out spam and emails that contain certain types of attached files.
You can also use rules to direct mail, such as a newsletter, into a specific mailbox.
IMail Administrator supports the following two types of delivery rules:
Inbound Delivery Rules (on page 246). Inbound Delivery Rules apply to incoming
mail that is sent by a non-local user. These rules can be created at three levels: e-mail domains, individual users, and list-server mailing lists.
Outbound Delivery Rules (on page 247). Outbound delivery rules filter messages
that are sent out by local users through IMail Server and can be created only at the domain level.
Both Inbound and Outbound rules support multiple rule conditions. Delivery rules can also be used in conjunction with forwarding or the Auto Responder to re-route mail from one user to another. For example, a system administrator could route messages containing particular words to a reviewer.

Examples of Delivery Rules (on page 262)
How Rules are Stored and Processed
All inbound rules are stored in the rules.ima file. Since inbound rules can be created for mail domains, users, and mailing lists, there can be multiple rules.ima files on your IMail
Server. The location of the rules.ima
file differs depending on whether the rule is for a mail domain, a user, or a list server mailing list.
244
IMail v12 Administrator Help
For a mail domain, the rules.ima
file is located in the mail domain's top folder.
For a user, the rules.ima
file is located in the user's folder.
For a list server mailing list, the rules.ima
file is stored in the list's folder.
Outbound delivery rules are stored in the orules.ima file. Since outbound rules can only be created for mail domains, the orules.ima
file is located in the mail domain's folder. If you have more than one mail domain on your IMail Server, you may have multiple orules.ima
files, one file for each host.
IMail Server reads the rules.ima
and orules.ima
files during the delivery process. The rule files for the virtual domain are evaluated first, then the rules for users and lists. For more
information, see IMail Processing Order (on page 28).
Any rules.ima or orules.ima
file can be copied to other directories. For example, if you create inbound delivery rules for one user, you can copy the rules.ima file to the directories of other users to apply the same rules to them.

Using IMail Rules to Filter Spam
Delivery rules are powerful for filtering spam because they offer more options for processing messages than the anti-spam components. When using the anti-spam components, if a message is identified as spam, you can delete it, forward it to an e-mail address, or insert an
X-Header. When using delivery rules to process a message, you can choose to Delete,
Forward, Move to Mailbox, Copy, or Bounce messages. Delivery rules can be set up at the e-mail domain and user levels.
If a message matches entries in the blacklists or fails a verification check, an X-Header is inserted into the message header. Additionally, phrase filtering and statistical filtering can be configured to insert X-Headers. If you want to filter a message with an X-Header, you can set up a rule to search for one of the X-Headers. If a message is trapped by a rule, it is immediately processed according to the action specified in the rule. spam, so that you can evaluate the messages that are trapped to ensure that no legitimate mail gets caught by mistake.

Adding Multiple Conditions for Domains
You can create multiple conditions for both inbound and outbound rules. By using multiple conditions, you can often combine multiple rules into one, thus, saving time and creating a more compact rules file. Sometimes a rule with only one condition is adequate to fulfill rule filtering requirements. However, when you need to create more complex rules, you may want to use multiple conditions. For example, see Rule with Multiple Conditions Example (on
To add a rule with multiple conditions:
1 Follow the instructions to create a rule as described in Setting Inbound Rules for Domains

Storing Search Strings in an External Text (.rul) File
If you need to frequently update and distribute the delivery rules search text, you can use external text files to store the search text. External files were designed to allow frequent updating of rules without creating a new rule.
Important: The following rules are required for external rules:
1. The External Rule file must exist in the same directory as the
"rules.ima"
or
"orules.ima"
file.
2. The External Rule file when referenced in the rule must not include the
".rul"
file extension.
3. The External Rule file must have a file extension of
".rul"
255
IMail v12 Administrator Help
Example:
(mortgage|loans|credit offer), where the pipes mean "or" and separate the conditions. Usage of the "and" condition is not permitted in a
".rul"
file. Also, the
".rul"
file must be located in the same directory as the
"rules.ima"
or
"orules.ima"
file.
To illustrate this, the administrator can use this method to catch mail from known spammers.
The administrator might create a text file named "spam1.rul". Each time a new spammer address is discovered, the administrator can add it to the " spam1.rul"
file. The
"rules.ima"
or
"orules.ima"
file can reference the text file named
"spam.rul"
. The procedure for storing search text in an external file is the same for Inbound and Outbound
rules. For more information, see External Text File Example (on page 256) and Rule Syntax (on
To create a delivery rule that references an external text file:
1 Select a mail domain, or the list that you want to create an external rule for.

Enter the name of the file in the second Search text box without the

"rulefilename"
where
"rulefilename"
is the name of the
".rul"
file you want to reference.
If the external text file does not exist, enter a new, unique name for the
".rul"
file.
Do not enter the file extension .rul because IMail will append it to the filename you enter.
1 Click Edit to open and edit the rule file in Windows Notepad (or your default text editor).
If the rules file does not exist, one will be automatically created. For information about
creating the search text, see Rule Syntax (on page 257).

Inbound delivery rule for a host. A school administrator can set up an inbound delivery rule that scans for offensive language in mail messages and deliver such messages to a special user account that can be reviewed by a faculty member. Example
Outbound delivery rule for a host. A school administrator can set up an outbound delivery rule that will scan for offensive language or content in mail messages that are being sent out
through IMail Server by a local user. Example (on page 264)
Inbound delivery rule for a list-server mailing list. A system administrator can set up an inbound delivery rule for a list-server mailing list to scan the body of all messages addressed to the list and scan for language that indicates that the e-mail came from a spammer or bulk mailer. If such messages are found, they can be deleted. For example, the rule can search for one of the following text strings:

Sending spam to a specific folder in a user account
You can allow your users to manage their own spam by directing all messages that are identified as spam into a folder for the user account. The user can then delete the ones that are spam, notify you of any false positives, or set up a forward file that will move specific messages into their Inbox.
To create a rule that moves spam into a specific sub mailbox:
1 Make sure that all of the anti-spam features are setup with the Insert X-Header action to be taken when e-mail is determined to be spam. For more information, see Setting
Inbound Delivery Rules for IMail Domains (on page 228).

Receiving Mailing Lists and Newsletters that are identified as spam
Sometimes, mailing lists and newsletters are identified as spam because they are sent from bulk mailers. If you do not want to place the domain from which a mailing list/newsletter is sent into the trusted addresses list, you can set up a rule to deliver the message anyway.
If there is already a rule setup to direct spam into a specific user’s mailbox (for example,
Spam), you can have the user create a rule as described below:
Look at the header of one of your mailing list/newsletter messages that was identified as spam. Find the X-IMAIL-SPAM line. Copy and paste this entire line into the text area for a rule.

Determining which Rule Trapped a Message
If a message is trapped by a rule, an X-IMail-Rule line is placed in the message header to allow you to know which rule caught the message. If multiple rules trap a message, only the first rule will be placed in the X line in the header. The X-IMail-Rule line will also contain up to 30 characters of the message data that caused the message to be trapped. Message data will not be included in the X-IMail- Rule line when a message is trapped by a negative rule (does not contain or does not equal).
If a domain rule traps the message, the X-IMail-Rule header will be added to all local deliveries. If a message is trapped by a user's rule, the X-IMail-Rule header will only be added to deliveries to the user. When a message that is destined for local delivery is trapped by an outbound rule, a line with the rule causing the trap will be written to the Queue file. When this message is delivered, and that line exists in the Queue file, it will be written as an
X-IMail-Rule line in the message header. Outbound messages that are not delivered locally will not have an X-IMail-Rule line in the header.
Example X-IMail-Rule line:
X-IMail-Rule: S~ Company Newsletter: Newsletter-Monthly Company Newsletter

Name of the mailbox to send the message to
Message text that caused the message to be trapped.
Disabling the X-IMail-Rule Header
If you want to disable the X-IMail-Rule header, so that it does not appear in the message header, you must add an entry to the registry. In the registry, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global and add the entry BlockRuleHdr with a non-zero value. This is a server wide setting and affects all domain and user rules on the server. If BlockRuleHdr is not present or is set to zero, then the X-IMail-Rule header is enabled and will be displayed in the message header. the X-IMail-Rule line is 199.
266
IMail v12 Administrator Help
Tip: The maximum number of characters that will be displayed in the message data section of the X-IMail-Rule line is 30. The Maximum length of any X- IMail-Rule line is 250 characters.
Because IMail Server inserts the rule and 30 characters of the message in the header, special care should be taken if a trapped message is then forwarded to another recipient. Some e-mail clients will include the header in the forwarded message. If this occurs and you have a rule set up to search the body of the message for the same text, then the message will be trapped again.

How Peering Works
Suppose you have two systems with IMail installed on each system and you set up the two systems as peer servers. Each system has a portion of the user database for a single mail host.
When mail is sent to an e-mail address, the sending server does a DNS lookup to get the mail domain name and address associated with the e-mail address. If the IMail Server that is handling mail for the message is configured for peering, mail comes in for a user on the mail domain and the mail is directed to one of the peer mail servers.
If the user is found on the peer server, the mail is delivered. If not, the peer server does an
"SMTP Verify" to see if the user exists on the other mail server. If the user is found in the user
273
IMail v12 Administrator Help
database, it forwards the mail. If either peer server is down, the other peer server receives and holds mail until the first server comes back up.
Note: When using peer servers, do not select the Disable SMTP "VRFY"Command on the
Services > SMTP tab. Peer servers need to use this command to verify a user that is on the other peer.

List Server Interaction
Since IMail Anti-virus scans all incoming and outgoing mail messages, special provisions apply concerning the list server. Normally, IMail Anti-virus would unnecessarily scan a list
283
IMail v12 Administrator Help
server message twice, once when the message comes in, and another time when the list server sends the message to the list. This would slow down the processing time.
Therefore, all messages destined for a list are marked as scanned (V1) before they are handed over to the list server. If you look in the queue at a list server message, it will always be labeled V1 (see chart above), no matter what stage the message is in. This tells IMail Server to skip the second scan since the file cannot be infected.

CHAPTER 8
Anti-spam
In This Chapter
Anti-spam Overview
IMail standard edition includes standard anti-spam technology; IMail Premium includes
Premium Anti-spam as well as Standard Anti-spam technology.
Premium Anti-spam
Commtouch Advanced Security Daemon (a.k.a. ctasd™) a plug-and-play email-borne spam and malware outbreak detection daemon that combines your current core messaging network infrastructure with advanced detection and classification capabilities. The daemon adds a layer of e-mail filtering to your mail delivery system in order to provide real-time classification, already in the first minutes after a new outbreak is launched.
Commtouch's GlobalView™ Mail Reputation Service fights unwanted mail at the perimeter, reducing more than 85% of incoming messages at the entry-point, before these messages enter the network. Additionally, GlobalView can optimize traffic flow so that legitimate sources gain optimal access, while unauthorized sources attempting to abuse the network are blocked.
Standard Anti-spam
All IMail products include standard anti-spam features. These features are custom configured by the administrator to identify spam and prevent it from clogging your Inbox. Mail messages are passed through several layers of filters and tests to assure that maximum spam detection is achieved.
What You Can Do with the Anti-spam Features
Use the Premium Anti-spam filter (optional only with IMail Premium) to automatically manage spam protection. Premium Anti-spam filter settings are applied before
Standard Anti-spam filter settings.
289
IMail v12 Administrator Help
Enable statistical filtering (on page 316) (content filtering) to analyze each message
and determine if it is spam.
Use phrase filtering (on page 303) (content filtering) to configure a phrase list that
searches for specific spam phrases within the subject and body of e-mail messages.
Enable HTML feature filtering (on page 305) to search messages for HTML tags that
could be used to disguise spam.
Create a URL Domain Blacklist (on page 313) that searches for domain names (URLs)
contained within HREF and IMG SRC HTML tags and in plain text messages.
Enable broken MIME header (on page 320) filtering to treat e-mails with malformed
MIME headers as spam.
Use the Sender Policy Framework (SPF) (on page 321) feature to increase the ability to
stop incoming e-mail from forged e-mail addresses (spoofed e-mail).
Use connection filtering (on page 333) to compare e-mail messages against
configurable realtime blacklists to determine if they are from IP addresses that are known to send spam.
Create a white list (trusted addresses) (on page 267) of e-mail addresses, domains, and
subnet masks that bypass content filtering.
Enable verification checks (on page 333) (connection filtering) to verify the "Mail
FROM" address, HELO/EHLO domain information, and perform a reverse DNS lookup on incoming e-mail messages.
Configure delivery rules (on page 245) to trap messages based on spam X-Headers
that are inserted when a mail message fails a spam test.
Which Anti-spam Settings are Used to Check a Message?
The anti-spam filters used to scan a message are determined by the IMail domain settings of the IP address that the message is received on. If the message is received on an IP address that is not configured for IMail, the primary domain's anti-spam filter settings are used.
Spam Actions
If a message is identified as spam, you can set IMail Server to delete it, send it to an e-mail address, or insert an X-header in the message to identify which spam test it failed. You can also create delivery rules to search for the spam X-Headers and process the message accordingly.
Accessing the Anti-spam Features
The Anti-spam options are accessed from two levels: the server level (on page 92) and domain

IMail v12 Administrator Help
Types of Anti-spam Filters
Sender Policy Framework (SPF) Filtering
SPF extends the Simple Mail Transfer Protocol (SMTP) and Domain Name System (DNS) so mail servers do not accept e-mail unless the sending computer is designated as a legitimate e-mail sender. This feature enables administrators increased capability to stop incoming e-mail from forged e-mail addresses.
Premium Anti-Spam
The optional Premium Anti-spam filter provides automated spam protection in addition to the Standard Anti-spam filter included in IMail. You can select actions to take if a message is determined to be spam.
HTML Filtering (on page 305) (Content Filtering)
HTML filtering examines only the HTML portions of an e-mail message, and is comprised of 3
components: an HTML parser (on page 307), HTML Feature filtering (on page 305), and a URL
Domain Blacklist. The HTML parser is part of the anti-spam engine that examines the HTML sections of a message. It extracts the text from HTML tags, and passes the text on to the phrase and statistical filters for examination. The HTML Feature filter allows you to specify which HTML tags you want to consider spam indicators. The URL Domain Blacklist searches for domain names that occur in the URLs of HTML messages.
Phrase Filtering (on page 303) (Content Filtering)
Phrase filtering searches for common spam phrases within the body and/or subject of an e-mail message and identifies the message as spam. Phrase filtering can be enabled/disabled per domain, and works independently of statistical filtering. For more information see Phrase
Statistical Filtering (on page 315) (Content Filtering)
Statistical filtering examines each word in the body of an e-mail and evaluates whether the word is a statistical indicator of spam. The entire message is then evaluated based on the
combined word counts (on page 368) to determine whether it is likely to be spam. You can
create a host specific exclude list, specify what action to take when a message is identified as spam, and specify whether to use the primary domain's word counts or create new ones. For
more information see Statistical Filtering (on page 315).
A list of words that are not included to determine whether a message is spam. The words in the exclude list are words that have an equal chance of being non-spam as spam. For example, "Mortgage" is a term frequently used in spam. However, if you work in the financial industry, this term may appear frequently as non-spam. In such a case, you can enter the word "mortgage" into the exclude list. The exclude list should also include common words like proper names. The exclude list is stored in the exclude-list.txt
file located in the mail domain 's directory.
291
IMail v12 Administrator Help
Attachment Blocking Filtering (on page 252)
Attachment blocking filtering lets administrators specify types of file attachments to block from e-mail messages and actions to take on blocked messages. Attachments can be blocked based on message MIME types and filename types. In addition to selecting the types of message attachments to block, you can define actions to take on blocked messages.
Broken MIME Header Filtering (on page 320)
The Broken MIME Header filter identifies Broken MIME header characteristics that result in
SPAM e-mail. You can also define actions to take when Broken MIME headers are identified as
SPAM e-mail.
Delivery Rules (on page 245)
You can use domain and user delivery rules to process messages based on the spam
X-Headers which are inserted when a message fails a spam test. For more information see
Using Delivery Rules to Filter Mail (on page 245).
Anti-spam Configuration Overview
The following topics explain the basic tasks you must complete to configure the IMail Server anti-spam features. Completing each of these steps establishes your unique spam signature, which determines how IMail Server handles spam. After these tasks are completed, your server will be protected from spam. Also, after you complete the basic setup tasks, you may want to read the Advanced Statistical Filtering topic to learn about other ways to configure the anti-spam features.
Basic Setup Tasks
To set up the basic anti-spam configuration, complete the following steps:
Server Configuration:
Configure Realtime Blacklists for the Server (on page 336)
Configure Logging Options (on page 343)
IMail Server Domain Configuration:
Configure Connection Checks (on page 333)
Configure SPF Filtering (on page 321)
Configure Premium Anti-spam (optional)
Configure Content Filtering
Configure HTML Filtering (on page 305)
Configure Broken MIME Header Filtering (on page 320)
292
IMail v12 Administrator Help
Enter White List (Trusted Addresses) (on page 267)
About Your Spam Signature
All of the anti-spam features that you have configured for IMail Server are collectively referred to as your spam signature. It consists of your specific configurations for:
White lists (trusted IP, domain, and e-mail addresses)
Realtime blacklists
Verification checks
Sender Policy Framework (SPF)
Premium Anti-spam
Phrase filtering
Statistical filtering
HTML feature filtering
URL domain blacklist filtering
Broken MIME header configuration
If you have too many false positives or are not catching enough spam, you may need to adjust your spam signature.
IMail Anti-spam Processing Order
The following steps indicate the order in which each anti-spam component performs, assuming that all default options and settings are not altered after installation. This order can change when enabling/disabling "Apply Domains/E-Mail Addresses to content filtering only" options, otherwise messages are processed as follows:
1 White List (on page 267) (Trusted Addresses). IMail checks the Apply to Anti-spam
option. If this option is enabled, then the IP address (and address present in the MAIL
FROM command) for an incoming message is compared against the white list to see if there is a match. If there is a match, all other anti-spam checks are skipped. However, if the IP address (or MAIL FROM address) does not match, the message is compared
against the Realtime Blacklists (on page 129).
(on the White List page), then Realtime Blacklists, Verification Tests, and SPF (on page 321)
checks are performed against the message; even if the address in the MAIL FROM command is present on the White List page.
2 Connection Checks (on page 333). IMail Server initiates connection filtering to
compare a message’s sender information against configured Realtime blacklists. If the message matches a blacklist, it is processed according to whether the blacklist is a
“trusted” or standard blacklist. If the message does not match a blacklist, verification checks are performed.
293
IMail v12 Administrator Help
3 Verification checks (on page 333). If enabled, verification tests are performed to verify
the "Mail FROM" address, the HELO/EHLO domain, and a reverse DNS lookup is performed. If a message passes all the checks, content filtering is performed. If a message does not pass all checks, an X-Header is inserted into the message or the message may be deleted. SPF checks are performed next.
4 SPF Filtering (on page 321). The SPF feature provides increased capability to stop
incoming e-mail from forged e-mail addresses. Using a sender authentication scheme, a domain owner requires that legitimate messages from a domain must meet certain SPF criteria. Messages that do not meet the criteria are not accepted as a legitimate e-mail messages and are processed according to the SPF options selected on the SPF tab.
5 Trusted Domains/Email Addresses (on page 267) (on the White List page). If the
Apply to Domain/EMail Addresses to Content Filtering Only option is selected, IMail
Server checks whether the connecting SMTP server’s Domain/EMail address is listed in the Domain/EMail Addresses list. If it is listed, the content is not scanned further with content filtering.
6 Premium Filter. The Premium Anti-spam filter (optional in IMail Premium only) provides automated spam protection in addition to the Standard Anti-spam filter included in
IMail. If a message does not pass the Premium Anti-spam filtering, actions selected are applied before Standard Anti-spam filter settings.
7 Broken MIME Header (on page 320). If enabled, the filter identifies broken MIME
header characteristics that may be present in SPAM e-mail. You can define actions to take when broken MIME headers are identified in SPAM e-mail. If it is not filtered as a broken MIME header, the message is passed on to either HTML filtering or phrase filtering, depending on whether it contains HTML code.
8 HTML Feature Filtering (on page 305). The HTML content filtering occurs during the
Phrase Filtering and Statistical Filtering process. If HTML filtering is enabled, the message is examined to determine if it contains HTML code. If it does, the message
undergoes HTML Content Filtering (on page 305). If the message does not contain
HTML components, Phrase Filtering and Statistical Filtering continue to evaluate the message.
Feature Filtering. When a message with HTML code is evaluated, it is compared
against the Feature Filtering (on page 305) options to detect certain HTML code
components that may be present in the message. If the selected HTML code components are present, selected actions are taken on the message.
URL Domain Blacklist. When a message with HTML code is evaluated, it is also
compared against the URL Domain Blacklist (on page 313) to search for domain
names that may be present in the message URL links. If a URL that is identified in a message matches a domain name included in the URL Domain Blacklist, selected actions are taken on the message.
9 Phrase Filtering (on page 303). If phrase filtering is enabled, the message is checked to
determine if it contains phrases that are in the phrase list. If the message passes, it is processed according to the settings for phrase filtering. If the message does not pass, it is processed by statistical filtering.
10 Statistical Filtering (on page 316). If statistical filtering is enabled, the message is
compared against the spam and non-spam word counts to determine if it is statistically likely to be spam. If it is identified as spam, it is processed according to the settings for statistical filtering. If the message is not identified as spam, it is delivered.
For information on how these anti-spam components integrate into IMail Server mail
processing, see IMail Server Processing Order (on page 28).

Installing Updated Anti-spam Files
Ipswitch maintains several files that are available for download from our website, including an antispam-table.txt file, phrase-list.txt file, and a spamblkm.txt file. These files provide you with updated spam information and are also useful for reverting back to the default configurations. You can download these files from the following locations:
ftp://ftp.ipswitch.com
/Ipswitch/Product_support/IMail/antispam.zip ftp://ftp.ipswitch.com/Ipswitch/Product_s
upport/IMail/antispam.zip
The IMail Ipswitch Support Center at the following location: http://www.imailserver.com/Support.
Explanations of Files
Spam and Non-Spam Word List (antispam-table.txt)
Ipswitch continuously updates the antispam-table.txt file in order to keep up with spammers. As we collect new spam statistics, it is integrated into the existing antispam-table.txt file, and the file is then made available to users.
List of Default Blacklists (spamblkm.txt)
This is a list of the default blacklists used in IMail Server.
Sample Phrase List (phrase-list.txt)
The sample phrase list is provided to assist you in setting up phrase filtering. You may want to examine this file before enabling it in to assure that all of the phrases are suitable for your needs.
Sample URL Domain Blacklist (url-domain- bl.txt)
The sample URL Domain Blacklist is provided to let you enable and run the URL Domain
Blacklist feature with minimal effort. The URLs contained in this list are ones that we have collected from spam e-mail. You may want to examine this file before enabling it, to assure that you agree with the domain names that it contains.
Forwarding Spam to Commtouch
The Premium Spam Filter performance can be improved when users forward spam e-mail to
Ipswitch. Ipswitch provides the spam mail to Commtouch Advanced Security Daemon
(ctasd™) editors to review the spam submission and add spam signature information to it.
Then the signature is published to the global database to help other users eliminate spam.
For maximum protection, this global database is updated on your IMail Server every few minutes.
Reporting e-mail that is spam to Commtouch:
1 Obtain the message as it was originally received.
2 Send the message as an attachment to [email protected]
(mailto:[email protected]) with the following subject line:
[FN Report][Messaging Architects][Date]
295
IMail v12 Administrator Help
Note: Only the Date tag should be modified. Example:
[FN
Report][Ipswitch][mm/dd/yyyy]
Reporting False Positives (Legitimate mail flagged as spam)
1 Submissions must contain the Commtouch
"RefID"
from the header of the message.
You can forward the original message as an attachment (
"RefID"
header line included) or retrieve the
"RefID"
and put it in the body of your submission. It is ok to send more than one
"RefID"
per message.
Header line example:
X-CTCH-RefID: str=0001.0A010208.492285A9.0064,ss=4,pt=62280,fgs=12
2 Send the message to [email protected] (mailto:[email protected]) with the following subject line:
[FP Report][Ipswitch][Date]
Note: Only the Date tag should be modified. Ex: [FP Report][Ipswitch][mm/dd/yyyy]
Important: This process is only intended for messages that were improperly flagged by
Commtouch Premium Anti-spam. If the message was flagged by other IMail spam filters you must manually adjust the filter to prevent further false positives.
Forwarding Spam Messages (Example)
To forward spam messages, enter an e-mail address in the form of [email protected] . If the address is located on the same domain, you can omit the domain and only enter the User ID.
Mailbox Size limit set in the Domain Properties (on page 42). If you receive a large quantity of
spam, this limit could be exceeded for the mailbox that stores spam. Make sure that you delete messages from this mailbox on a regular basis. You may also want to set up a Full
Mailbox Notify Address for e-mail to be sent to when a mailbox is almost full. For more
information, see Setting Domain Properties (on page 42).
If you want the spam to be sent to a mailbox, place a hyphen between the user and sub-mailbox name, such as root- [email protected]. If the account is located on the same mail domain, you can omit the domain and enter root-spam. created only if Create is selected in the Sub-Mailbox Creation options of the Domain
Properties. For more information, see Setting Domain Properties (on page 42).

Anti-spam FAQs
Will the anti-spam features slow down mail processing?
Under normal circumstances, the anti-spam features will not impact mail delivery. However, the verification options may slow down the server, as they are resource intensive.
How does the anti-spam engine interact with IMail Anti-Virus?
IMail Anti-virus complements the anti-spam features of IMail Server. Connection filtering and verification for anti-spam are completed first, followed by the Anti-Virus scan. Then, the other anti-spam processes are initiated, beginning with content filtering. See also IMail Processing
What can I do if legitimate mail is identified as spam?
You can place the e-mail address or domain name, from which the message was sent, in the
white list (trusted addresses) (on page 267) to always let messages from the e-mail address or
domain name to be delivered.
If a small number of messages are being misidentified, you can use the antispamseeder.exe
(on page 354) utility to add the messages to the antispam-table.txt file. This will increase the
likelihood that similar messages will be correctly identified in the future.
If a large number of legitimate mail is being identified as spam, modify the Advanced Options on the Statistical Filter page. Begin by increasing An e-mail is spam when it's calculated probability exceeds option to 95%. If that has no effect, decrease The Probability a new word is spam option to 10%. See Also Advanced Statistical Filtering.
How do I know if the blacklists are accurate?
The blacklists used are not maintained by Ipswitch, therefore we cannot verify their accuracy.
Some blacklists are updated more frequently than others, and contain more accurate information. You should be aware of this especially if you decide to configure your own blacklists. For your convenience, IMail Server allows you to identify trusted blacklists. These are blacklists that you have tried and found to be accurate.
Where does Spam go?
By default, messages that are identified as spam are forwarded to a mailbox called "bulk" within the root account. If you have changed the "Forward To" setting, on any of the anti-spam filter pages, then spam goes to the address that is entered in this field.
How do I access the Anti-spam features?
Only system and domain administrators can access the anti-spam tabs. System administrators have access to the server level realtime blacklists and logging tabs. Domain administrators have access to the domain level realtime blacklists, connection filtering, statistical filtering, phrase filtering, and trusted realtime blacklists.
297
IMail v12 Administrator Help
The anti-spam tabs can be accessed from two places: the server level and host level. To access the server Realtime Blacklists page, click the IMail Administrator System tab, then click
Realtime Blacklists. The Realtime Blacklists page opens.
To access domain (host) level settings, click the IMail Administrator Anti-Spam tab. The
Anti-Spam Settings page opens. The domain level anti-spam options are displayed on the
Domain Level Spam Filtering page.
Will the anti-spam features affect mailing list subscriptions?
Most mailing list subscriptions will not be identified as spam. However, to ensure that mailing list messages are not identified as spam, place the domain name from which the mailing list is sent in the Trusted Addresses list. For more information, see Creating Trusted Realtime
If you do not trust the domain, you can create a host rule to send the message to a folder for the user (for example, spam), and the user can create a user rule that puts the message in
his/her Inbox. For more information, see Using Delivery Rules to Filter Spam (on page 245).
Do the anti-spam features work with Web Messaging?
Yes. IMail Server processes mail from IMail Web Messaging in the same way it processes all other mail.
Do I need to use the Antispamseeder.exe utility to alter my word counts?
The file, that ships with the product, is appropriate for most users. However, you may need to alter this file if we have identified words as spam that you do not consider to be spam, or vice versa. For example, the word "mortgage" is identified as spam because in our tests, it occurred 364 times in non-spam, and 7516 times in spam. However, at financial institutions, the word "mortgage" is a non-spam word that occurs frequently. In this case, you need to alter the antispam-table.txt file so that statistical filtering recognizes the word "mortgage" as non-spam. For more information, see Customizing a Host's Antispam-table.txt file (on
Will the anti-spam features prevent my users from sending spam?
The anti-spam engine automatically filters mail from all users who are not authenticated. An authenticated users e-mail will then bypass all anti-spam filtering.
Authenticated users are users who have SMTP Authentication enabled on their e-mail client or users who send mail from IMail Web Messaging. By default, IMail Server forces users to authenticate, unless you select another option such as Relay Mail for Anyone or Relay Mail
for Addresses in the Mail Relay Settings located under Services tab > SMTP. This means that every time a user connects to the IMail Server, he/she must enter his/her user ID and password.
298
IMail v12 Administrator Help
Should I place a domain name in the phrase list or in the URL Domain
Blacklist?
Each location serves a different purpose. The phrase list filters the domain name as it appears in normal text in the body of an e-mail message. The URL Domain Blacklist will filter the domain name if it appears as a link in HTML code within a message, specifically within HREF and IMG SRC tags.
Spam Filtering (Domain Level)
How to get here
Use the Domain Level Anti-spam settings to enable, change, and disable various anti-spam filters for the selected domain.
Premium Filter. (Optional only with IMail Premium). Provides fully automated spam protection in addition to the Standard Anti-spam filter included with all IMail products.

Premium Connection Checks (IP Reputation)
Commtouch's GlobalView™ Mail Reputation services are used primarily to weed out spam messages and email-borne malware at the entry point before these messages enter the customer’s messaging network, thereby relieving the need for resource-consuming downstream filtering. This is accomplished by applying the most up-to-date IP reputation data to the sender IP, before the SMTP connection is accepted.
By applying GlobalView Mail Reputation services to the senders’ IP addresses before or during the SMTP session and before their messages enter the messaging network, ctIPd delivers cost-effective benefits such as the following:
Reduce IT resources such as server count, CPU load, storage, etc.
Eliminating multiple security risks
Reducing the level of false positives
Minimizing the cost of downstream filtering
Lowering the overall bandwidth consumption
Optimizing IT labor required to manage the overall messaging process
Additionally, Commtouch GlobalView Mail Reputation services are used as part of an overall strategy to optimize network accessibility so that the network’s messaging processes are efficient and focused on allowing legitimate sources full and uninterrupted access. At the same time, the Commtouch GlobalView Mail Reputation services also make access for

The following actions for Commtouch IP Reputation are:
Log Only (Set by default). This setting will take no action on any messages, except to log. Connection checks will be made but all messages will be delivered as usual after logging.
Disabled. This will disable logging and all connection checks.
Log With Action. This setting will allow the following connection checks.
Throttle connections identified as suspected, yet unconfirmed, spam sources.
Reject connections identified as confirmed spam sources.
Reject and throttle connections on the MAIL FROM command. (Set by default)
With IP Reputation enabled, messages will be validated for rejection at the MAIL
FROM command and return a 550 error to the sending mail server.
Reject and throttle connections on the DATA command. With IP Reputation enabled, messages will be validated for rejection at the DATA command.
Warning. Setting IP Reputation to validate on the DATA command allows malicious IP's to harvest valid e-mail addresses; since the RCPT TO command occurs before the DATA command.

A Note about Entering Domain Names
When you enter a domain name into the phrase list, IMail Server will filter the domain name if it appears in the normal text in the body of an e-mail message. It will not filter domain names found in URLs or links. To accomplish this, you must enter the domain name into the URL
Domain Blacklist. The URL Domain Blacklist filters the domain name if it appears as a link in
HTML code within a message, specifically within HREF and IMG SRC tags.
Normalizing Words
When the Normalize Words option is selected, all words in a message are normalized before they are added or compared to the phrase list or antispam-table.txt file. Normalizing consists of stripping out all non-alphabetic characters (any character other than A-Z, a-z).

Overview of HTML Filtering
For each HTML section of an e-mail, the HTML filter processes the text outside the angle brackets of an HTML tag as before. The HTML filter processes the text within the angle brackets of an HTML tag as follows. The HTML filter first checks to see if the tag is one of the features the filter has been configured to search for. If it is, the HTML Filter counter counts the number of features found. The e-mail is considered spam if the number of HTML features found equals the number configured for the feature's found count.
HTML filtering is part of content filtering, but is used only on HTML portions of a message.
The individual components of HTML filtering are discussed below.
Types of HTML Filtering:
HTML Parser
The HTML parser is always used on HTML messages. The parser decodes the HTML code and tags until the text appears as it would when the message is opened. The parser then sends the text on to be processed by statistical and phrase filtering to determine if it is spam.
HTML Feature Filtering
HTML feature filtering lets you define certain HTML tags that will be spam indicators. The
HTML features include Nested Table (on page 307), Hyperlink (on page 308), Script Tag (on
page 309), Invalid Tag (on page 308), Image Tag (on page 308), Mailto Hyperlink (on page 309),
Deceptive URL (on page 309), Embedded Comment (on page 310). If a message contains a
configurable number of these HTML features, it is identified as spam.
URL Domain Blacklist
The URL Domain Blacklist is a configurable list of domain names that are known to send spam. IMail Server extracts the primary domain from an http link to determine if the domain name is in the URL Domain Blacklist. It does this by looking for domains that are used in HREF and IMG SRC tags in the HTML code. If the primary domain matches any of the domain names in the URL Domain Blacklist, the e-mail is considered spam and the appropriate spam action is taken.
Why do I need HTML Filtering? Why doesn’t the Phrase and
Statistical Filter Work?
Spammers use a variety of techniques to get around anti-spam programs that filter on words.
The primary way they do this is by disguising the message text in HTML e-mail so that is does not look like text. Unfortunately, if a word does not look like a word, the phrase and statistical filter will not be able to determine if it is spam. The HTML filter component solves this problem by decoding the HTML code to reveal the text, which is then passed on to the statistical filter for word analysis.

Nested Tables
Nested Table
307
IMail v12 Administrator Help
A nested table is a table within a table in HTML code, it is displayed as a table tag (<TABLE>) within a table tag. The following is an example of the HTML code for a nested table.
<table>
<tr>
<td>
<table>
<tr>
<td>
Get Paid $1000 A Week To Work From Home.
</td>
</tr>
</table>
</td>
<tr>
</table>
Hyperlinks
Spammers often include links in their messages as a way to get you to visit a website. An
HTML link in a message looks like the following:
<a href="http ://www.ipswitch.com /sla/index"</a>
This may or may not be accompanied by a tag calling an image or graphic. You should be careful when selecting this feature to filter on. Many legitimate HTML e-mail messages contain links in them, and as such would be identified as spam.
Image Tags
Spammers often put images into messages to hide the text from the content filter. Images are characterized by the following HTML code: <IMG src=filename>
Since there are no words outside the HTML tag in the above example, you would only see a graphic when you open the message. The statistical filter alone would not decipher this
HTML code, because all words are included within the HTML tag. But the HTML parser will decode the HTML to see if it contains any Image tags.
If you want all messages containing IMG SRC tags to be considered spam, select this option under HTML Feature Filtering.
If you want the domain name in such a tag to be considered a spam indicator, place the domain name in the URL Domain Blacklist.
Invalid Tags
Spammers sometimes insert the message text inside invalid HTML tags in an attempt to confuse statistical word filters. This is because the text, in the invalid tag, is treated as non-spam words and they balance out the spam words. Some examples are shown below:
Examples:
308
IMail v12 Administrator Help
<comment>Get Rich Quick</comment>
IMail Server treats all non-standard comment formats as invalid tags.
<Get paid to work from home. Respond now for information on this fantastic offer.
There are a limited number of available positions, so don’t miss out. Respond Now!>
In the example above, text e-mail clients hide the message because it appears within an invalid HTML tag.
If you select the Invalid Tag option in HTML Feature Filtering, messages containing this type of spam trick will be identified as spam.
Script tag
Spammers sometimes create an entire message composed of nothing but script, such as
Javascript. Before the message is loaded, there are no words that the statistical filter would be able to identify. When the message is loaded, the text is displayed as normal, instead of the script.
The HTML parser ignores the script tag in messages. Therefore, if you want messages with scripting to be identified as spam, select Script Tag under HTML Feature Filtering. IMail will identify all messages containing such a tag as spam.
Mailto: Hyperlink
A Mailto hyperlink allows you to send e-mail directly from a web page, or in this case, an e-mail by clicking a link. The link opens up a new message window in your e-mail client with the recipients e-mail address filled in. Spammers use mailto hyperlinks as a way to get feedback from you.
Example:
<a href="mailto:[email protected]">Email Us</a>
Deceptive URLs
Spammers sometimes encode URLs to conceal the hostname or IP addresses from a content filter. Select this option to identify messages with deceptive URLs.
When IMail checks for deceptive URLs, the domain component of the URL is decoded first, then it is checked against the URL Domain Blacklist. If the domain component of the URL is found in the URL Domain Blacklist, the e-mail is treated as spam. The following are examples of deceptive URLs:
Plain text examples:

http://3468664375@3468664375/o%62s%63ur%65%2e%68t%6d
Embedded Comment
Sometimes spammers place a comment in the middle of a word, as shown in the example below:
VIA<!--text here-->GRA
This causes a single word, in this case VIAGRA, to be viewed as two words (VIA and GRA) by the e-mail client. Often, the comments themselves contain neutral words that spammers intentionally use to throw off statistical filters. The statistical filter would not catch this, because it cannot distinguish that there are HTML tags in the text. It would look for the words
VIA and GRA when comparing the message to the
antispam-table.txt
file. Now, the
HTML parser will extract the comments from the text, so that it can be examined by statistical filtering.
However, if you want embedded comments to be considered spam indicators regardless of the text, select this option under HTML Feature Filtering.
Deceptive Text
When the text of an html message is encoded. For example, text outside an html tag is considered encoded when it is in the format of &#ddd where ddd is a decimal number in the range: 48-57, 65-90, or 97-122.
Example
In an effort to get around antispam tests, the following encoding:
<i><strong>There is no
consultation
fees and
absolutely no
obligation.
You will
be amazed at
the rates we

310
IMail v12 Administrator Help
provide.</strong></i>
Displays the following message:
There is no consultation fees and absolutely no obligation. You will be amazed at the rates we can provide.
Example HTML Feature Configuration
You should be aware that some of the HTML features available for filter selection are common to all HTML messages, not just spam (i.e. hyperlinks). Selecting one of these features may cause false positives. As you gain experience with the HTML feature filtering options, you will be able to modify the settings based on your preferences. However, below you will find a suggested initial configuration that will enable you to use the HTML feature filter with success.
1 Select Embedded Comment and Deceptive URL. Both of these elements, especially when they occur together, are strong indicators of spam. Make sure that all other HTML features are cleared.
2 Select 2 from Number of options detected for an e-mail to be considered spam. This requires that both an embedded comment and a deceptive URL be present in a message for it to be considered spam.
3 For the option labeled Action taken on e-mail determined to be spam, select Insert
X-Header.
By selecting the Insert X-Header option, your messages are still delivered. You may want to create a delivery rule that moves such messages to a specific mailbox. For more information,
see Using Delivery Rules to Filter Spam (on page 245).
X-Header Example 1
The above X-Header indicates that the IP address of the message’s sender was found in the
FIVETEN blacklist, which suggests that it is spam.

Statistical Filtering
Statistical filtering uses the Bayesian spam filtering technique to calculate the probability of a message being spam based by its contents. Unlike simple content-based filters, Bayesian spam filtering learns from spam and from good mail by examining each word in the body of an e-mail message to determine if it is spam. Each word within a message is compared against known spam and non-spam word counts, and assigned a value based on whether the word is likely to be spam. Then, the entire message is assigned a probability based on the assessment of all combined word counts. If a message is identified as spam, you can choose to delete it, forward it to an e-mail address, or insert an X-Header into it. Words that contain non-alphabetic characters, such as numbers, are treated differently from other words. For
more information, see Identifying Wildcards in E-mail (on page 366).
315
IMail v12 Administrator Help
To increase the chances of legitimate messages not be identified as spam, you can create a host-specific exclude list. The exclude list contains words that you do not want to be included in the statistical analysis, because they are just as likely to appear in non-spam messages as they are in spam messages. The exclude list is stored in the exclude-list.txt file, which is located in the domain’s directory.
A list of words that are not included to determine whether a message is spam. The words in the exclude list are words that have an equal chance of being non-spam as spam. For example, "Mortgage" is a term frequently used in spam. However, if you work in the financial industry, this term may appear frequently as non-spam. In such a case, you can enter the word "mortgage" into the exclude list. The exclude list should also include common words like proper names. The exclude list is stored in the exclude-list.txt
file located in the mail domain 's directory.

A list of words that are not included to determine whether a message is spam. The words in the exclude list are words that have an equal chance of being non-spam as spam. For example, "Mortgage" is a term frequently used in spam. However, if you work in the financial industry, this term may appear frequently as non-spam. In such a case, you can enter the word "mortgage" into the exclude list. The exclude list should also include common words like proper names. The exclude list is stored in the exclude-list.txt
file located in the mail domain 's directory.
Statistical Filtering uses the Bayesian spam filtering technique to calculate the probability of a message being spam based by its contents. Each word in an e-mail message is examined and evaluated depending on how often the word appears in spam and non-spam e-mail. The entire message is then evaluated based on all of the word values to determine whether it is likely to be spam.
Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.

These options control the underlying functionality of the statistical filtering feature and are dependent upon each other to effectively identify spam. If you have a significant number of legitimate messages that are being identified as spam (false positives) or vice versa, you may need to adjust these options. experienced administrators modify these settings. Setting these options too high or too low could hinder IMail Server's ability to identify spam.
Advanced Options
The probability a new word is spam (default value is 40%). The percentage assigned to new words to determine if they are spam. Enter a value between 0 and
100%.
The higher the value, the more likely a new word will be treated as if it had previously appeared in spam e-mail messages. The lower the value, the more likely a new word will be treated as if it had previously appeared in non- spam e-mail messages. For example, if you enter 0, every new word will be treated as if it were non-spam. If you enter 100%, every word will be identified as spam.
We recommend that this value not be set higher than 40%. The idea behind setting this option at 40% or less is to bias the statistical analysis in favor of being legitimate e-mail, thereby reducing the likelihood of a false positive.
Example: If this option is set to 20%, a new word will be treated as having appeared in spam emails 20% of the time and as having appeared in non-spam emails 80% of the time.
An e-mail is spam when its calculated probability exceeds (default value is
90%). The closer the value is to 100%, the less likely that spam will be caught. The closer the value is to 0, the greater the probability that you will have false positives.
Enter a value between 0 and 100%.
This option sets the minimum probability percentage at which a message will be identified as spam. Messages with probability values below the value entered are identified as non-spam. Messages with probability values above this value are identified as spam.
Example: Suppose this option is set to 80%. If an e-mail message is processed and the combined probability for all of the word values within it is 60%, then this message is identified as non-spam because it does not meet the probability benchmark of
80%.
Example: If the word "Stop" appears in an e-mail for the first time, it is considered a new word and assigned a probability of 40% (probability a new word is spam). If you have the "spam calculated probability exceeds" set to 90%, then "stop" is not considered to be spam. In order for "stop" to be considered spam, its probability will have to increase from 40% to 90%.

IMail v12 Administrator Help
Maximum number of words used when calculating probability (default value is
15). The number of individual word values, within each e-mail, used to calculate the probability that an e-mail is spam. You can enter any value in this text box; however, entering anything above 25 may have unpredictable results.
Each word within an e-mail is assigned two word counts: the number of times the word has occurred in spam, and the number of times that a word has occurred in non-spam. From these values, a spam probability is computed for the word. This setting examines the words whose probabilities deviate most from an average word.
These words are both spam and non-spam words.
Example: Suppose this option is set to 15. Since most words have an average spam probability of 50% (50% likely to be spam, 50% likely to be non-spam), then the fifteen words that are farthest away from 50% are used. So if a word has a spam probability of 5% it will most likely be used. Likewise, if a word has a spam probability of 90%, it will most likely be used. A word that has a 45% probability will most likely not be used.
A list of words that are not included to determine whether a message is spam. The words in the exclude list are words that have an equal chance of being non-spam as spam. For example, "Mortgage" is a term frequently used in spam. However, if you work in the financial industry, this term may appear frequently as non-spam. In such a case, you can enter the word "mortgage" into the exclude list. The exclude list should also include common words like proper names. The exclude list is stored in the exclude-list.txt
file located in the mail domain 's directory. can greatly affect the performance of statistical filtering. The greater the value, the more time is spent determining which words to evaluate within a message. Thus, statistical filtering takes longer to calculate the e-mail probability and mail processing takes longer.

SPF Filtering
How to get here
IMail uses Sender Policy Framework (SPF) to extend the Simple Mail Transfer Protocol (SMTP ) and Domain Name System (DNS) so IMail Server does not accept e-mail unless the sending computer is designated as a legitimate e-mail sender. This feature provides administrators increased capability to stop incoming e-mail from forged (spoofed) e-mail addresses.
To accomplish this e-mail security measure, SPF establishes a policy framework and a sender authentication scheme that verifies the identity of e-mail servers (domains) for incoming messages. SMTP receivers (such as IMail Server) use this information to evaluate whether the message is from an e-mail server that is authorized to send e-mail from the message sender.
321
IMail v12 Administrator Help
Messages that do not meet the SPF criteria are not accepted as a legitimate e-mail message
and are processed according to the SPF settings selected on the SPF page. (on page 322)
How does SPF work?
SPF policy data is published on a DNS server in a .TXT record. DNS resolvers typically cache
SPF data to reduce lookup traffic. Sender domains do not have to run new servers to advertise SPF information; instead, SPF uses the connecting client 's IP address and information from the SMTP envelope to evaluate the SPF policy document published via DNS.
After the policy is evaluated, the message is classified and handled accordingly. For additional information about SPF, go to the SPF community at http://spf.pobox.com http://spf.pobox.com/.
Example:
If a spammer forges mail from the mail server imaspammer.com and uses a different domain in the From address, such as [email protected], the receiving e-mail server checks the SPF record for notaspammer.com. If it finds that [email protected] is not listed as a legitimate e-mail sender on notaspammer.com, the message fails and is processed by the SPF settings on the SPF tab.

Setting up an SPF record
Although you do not need an SPF record on your DNS server to evaluate incoming e-mail against SPF policies published on other DNS servers, the best practice is to set up an SPF record on your DNS server. Setting up an SPF record lets other e-mail servers use SPF filtering
(if the feature is available on the mail server) to protect against incoming e-mail from forged
(spoofed) e-mail addresses that may be associated with your mail server. As SPF records are implemented more widely, SPF filtering will become more effective at identifying spoofed e-mail messages.
About SPF records
SPF records, like MX, A, and PTR records, are included at the DNS domain tree level. These records identify authorized SMTP servers for each domain.
323
IMail v12 Administrator Help
An SPF record consists of the SPF version number followed by strings comprised of mechanisms, prefixes, and modifiers. SPF clients ignore TXT records that do not start with the version string v=spf1.
SPF records are evaluated in a two pass process. First, all mechanisms and prefixes are evaluated, then all modifiers are evaluated. Mechanisms are evaluated from left to right.
Modifiers are evaluated on the second pass and can occur anywhere in the record. A generic
SPF record takes the format of: version ([prefix] mechanisms) (modifiers)
SPF Parameters Description v=spf1 SPF version number all, include, a, mx, ptr, ip4, and exists Mechanisms. Use one or more in a record string.
"+", "-", "~", and "?" exp
Prefixes. Precede mechanisms. If a prefix is not included, "+" is implied.
Modifiers. Use 0 - 2 in a record string.
An example SPF record is: v=spf1 +a:mail.domain.com /16 +mx +ptr include:anotherdomain.com redirect=exampleredirect.com exp=spf-error -all
This SPF record includes three directives made up of prefixes and mechanisms:
+a:mail.domain.com/16
+mx
+ptr
-all and two modifiers: include:anotherdomain.com
exp=spf-error
Mechanisms identify IP addresses that are authorized to send e-mail from a specified domain.
You can use zero or more mechanisms in an SPF record string. Mechanisms usually contain ":" or "/" characters and are case-sensitive. Directives that do not contain "=", ":", or "/" are also mechanisms. Following are mechanism descriptions:
324
IMail v12 Administrator Help
SPF Mechanisms Description
all Matches all local and remote IPs and goes to the end of the SPF record. Example: v=spf1 +all include a mx
Specifies other domains that are authorized domains. Example: v=spf1 include:domain.com -all
Specifies all IPs in the DNS A record. Example: v=spf1 a:domain.com -all
Specifies all A records for each host's MX record. Example: v=spf1 mx mx:domain.com -all ptr ip4 exists
Specifies all A records for each host's PTR record. Example: v=spf1 ptr:domain.com - all
Specifies a single IP or an acceptable IP address range. /32 is assumed if no prefix-length is included. Example: v=spf1 ip4:192.168.0.1/16 -all
Specifies one or more domains normally singled out as exceptions to the SPF definitions. An A query is performed on the provided domain, if a result is found a match occurs. Example: v=spf1 exists:domain.com -all
Prefixes designate whether IP addresses pass or fail the SPF lookup test:
SPF Prefixes
+
-
Description
Pass. The address passed the test. Example: v=spf1 +all
~
?
Fail. The address failed the test. Example: v=spf1 -all
Softfail. The address failed the test, but the result is not definitive. Example: v=spf1 ~all
Neutral. The address did not pass or fail the test. Example: v=spf1 ?all
Modifiers provide additional SPF query information and can branch SPF processing. They always contain an "=" character and are case-sensitive. SPF includes two possible modifiers; each can be used once:
SPF Modifiers
redirect
Description
Sends inquiry to another domain. Example: redirect=exampleredirect.com
325
IMail v12 Administrator Help
exp Sets up an explanation in the SPF record. If an SPF query produces a FAIL result, the explanation is queried and the explanation string provides more information to the nonconforming user. The explanation is typically placed in an SPF log. Example: exp=spf-error

Connection Checks Overview
Realtime Domain Blacklists
Once the Realtime Domain Whitelist has been checked, Connection Checks will then continue validation checks for Realtime Domain Blacklists and Verification Checks (if enabled).
Realtime Domain Blacklists compare the sender information from incoming messages against the listed spam databases identified as spam.
Verification Checks
MAIL FROM address validation
Reverse DNS lookup for the connecting server
HELO / EHLO domain validation
The Administrator also controls whether the message should be deleted, dropped or only add an X-Header.
The action "Only Add X-Header" allows Administrators to test and review messages that have matches from the Realtime Domain Blacklists or failed Verification Checks that were set.
An X-Header is inserted in the message for every match made to a realtime domain blacklist or failed verification check. The e-mail is then passed on to content filtering for further examination. The message is delivered if no other rules processing takes place.
For the action "Reject Connection" and "Delete Message" each spam database listed in the
Realtime Domain Blacklist that identifies the sender as spam counts as a match and each validation check failure counts as a match. The Administrator must decide at what point the
total match count necessitates action to be taken. See Examples (on page 338).
Note: Realtime Domain Blacklists are not enabled by default.
Important: Realtime Domain Blacklists can only be added after the Realtime Blacklist at
the system level is setup.
Caution: A match made for a Trusted blacklist will immediately either delete or reject the message (includes action Only Add X-Header) depending on the Verification Checks setting for Blacklists.

Connection Checks
How to get here
Connection Checks has the capability for the following two types of validation checks once enabled, Realtime Domain Blacklists and Verification Checks. The Administrator also controls whether the message should be deleted, dropped or only add an X-Header.
The action "Only Add X-Header" allows Administrators to test and review messages that have matches from the Realtime Domain Blacklists or failed Verification Checks that were set.
An X-Header is inserted in the message for every match made to a realtime domain blacklist or failed verification check. The e-mail is then passed on to content filtering for further examination. The message is delivered if no other rules processing takes place.
For the action "Reject Connection" and "Delete Message" each spam database listed in the
Realtime Domain Blacklist that identifies the sender as spam counts as a match and each validation check failure counts as a match. The Administrator must decide at what point the
total match count necessitates action to be taken. See Examples (on page 338).
Note. Realtime Domain Blacklists are not enabled by default.
Important. Realtime Domain Blacklists can only be added after the Realtime Blacklist at
the system level is setup.
Caution. A match made for a Trusted blacklist will immediately either delete or reject the message (includes action Only Add X-Header) depending on the Verification Checks setting for Blacklists.
Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.

Blacklists. Name that the IMail Administrator assigns for his/her own identification.
This column displays all existing blacklists for the current domain. Click a blacklist to modify the blacklist options.
Type. This column displays the type of lookup that the blacklist performs.
Server. This column displays the domain name or IP address of the DNS server to contact for the corresponding blacklist's queries.
Tip: Leave the Server setting as an "*" unless otherwise specified by the blacklist instructions.
Query Domain. This column displays the domain that is queried for the corresponding blacklist.
Trusted. (By default no set) This check box will enable the selected blacklist to be handled as Trusted.
Note: Matches made to connections for a Trusted Blacklist are automatically rejected or deleted depending on the Verification Check setting for Untrusted Blacklists.
Add. Click Add to create a new blacklist (on page 336) for the current domain. For
more information, see Adding a Realtime Blacklist (on page 94).
Delete. To delete a blacklist, select its corresponding check box, then click the Delete button.
Verification Checks:
Select any of the following verification tests to perform on incoming e-mail messages. If Only
Add X-header is selected for action and a message fails for any of the checks, an X-Header is inserted into the message (Message will be deleted for trusted blacklists).
Verify MAIL FROM Address. Select this check box to have the "From" address of the connecting server verified for each message to ensure that the user is a valid user on the mail server. If the user or server does not exist, the message is identified as spam.
Note: Be aware that the MAIL FROM verification check may blacklist your domain by certain mail servers (Yahoo and Hotmail), for possible phishing of e-mail addresses.
334
IMail v12 Administrator Help
Perform Reverse DNS Lookup for Connecting Server. Select this check box to create a test in which the IP address of the connecting server is used to perform a reverse DNS lookup to determine the domain name. If a domain has a valid PTR record, the message is accepted. If a reverse lookup fails, it means there is no reverse record for that IP address and the message is marked as spam. An IP address with no
PTR record is usually either from a dial-up connection or spoofed message, both of which are indicators of spam. However, keep in mind that a significant number of legitimate mail servers do not have a reverse DNS entry. This may cause legitimate mail to be marked as spam (false positive
).
Verify HELO / EHLO domain. Select this check box to create a test in which the domain passed during the HELO/EHLO is used to perform a DNS query to verify that the domain specified has an A record or an MX record. If this test fails, an X-Header is inserted into the message. conversation with "HELO" or "EHLO".
Settings for Verification Checks and Blacklists
Action on Match
Reject Connection. Upon reaching the matched count the connection will be rejected with a 550 error returned to the email server.
Note: Administrators should be aware that the connection will not be rejected during the connecting IP or EHLO/HELO conversation. Connection will be rejected after the MAIL FROM, to avoid authenticating clients from receiving errors while sending mail.
Tip: This may cause delays in the SMTP conversation.
Delete Message. Upon reaching the matched count the message will be deleted.
Only Add X-Header. Selecting this option will add an X-Header for each Untrusted
Blacklist match, and for each failed Verification Check that is selected.
Important: Selecting the Only Add X-Header action, and a match is made for a Trusted
Blacklist the message will be deleted.
Perform action after this many matches. (Default is 1) This option works only with the Reject Connection and Delete Message. Only Add X-Header ignores this setting. The action will occur immediately after X number of matches. (Blacklist matches plus failed verification check options.)
6
Many blacklists used for connection filtering return hits for domains such as yahoo.com, hotmail.com, and msn.com, among others. If you use these blacklists, non-spam e-mail from these domains may be identified as spam and processed according to the specified spam action.
335
IMail v12 Administrator Help
Tip: Be sure the value entered is not greater than the total number of blacklists plus the number of verification check options selected.
Prefix Subject with. Select this option to work with Only Add X-Header to create a test in which, if selected, the subject of a message identified as spam by connection filtering is modified by inserting the text box.
Prefix Subject With will still apply for Reject Connection and Delete Message if a match has been made for a blacklist and/or verification check that is below the match criteria set for the action.
Note For Archiving Customers: Deleted Messages are archived, but Rejected Connections are not archived.

How to get here
Before adding to the Realtime Blacklist for a domain, be sure that it has been added to the
system level Realtime Blacklist, found at System > Realtime Blacklists (on page 92).
Realtime Blacklist selection will only display items that are enabled. This option is set in the
System > RealTime Blacklist. By default all items added to the System > Realtime Blacklist are enabled.
Note: Disabling an item in the System > Realtime Blacklist will automatically remove it
from the Connection Checks or Trusted Realtime Blacklist (on page 332). Should the item
be enabled at a later date it will automatically re-enable the list in Connection Checks or
Trusted Realtime Blacklist.

Server. This column displays the domain name or IP address of the DNS server to contact for blacklist queries. This field contains an asterisk (*) by default, which indicates that the default IMail Server DNS is used for blacklist queries, where it relays the DNS query to the DNS server for the blacklist. Using the asterisk eliminates the need to enter the IP address or domain.
Query Domain. This column displays the domain to query in the zone file. This name usually matches the server domain name. However, sometimes a blacklist will contain multiple zones to query on the same server. When this happens, the server name and the query domain will be different. The only way to know this is to read the documentation for the blacklist being used.

Using Anti-spam Log Entries
IMail Server logs all anti-spam events, such as error messages, to a separate log file. These events are stored in the log file that is selected in the Save Logs To list box in the Setting the
Anti-spam Logging Options (on page 343). The log files also contain text that is returned by a
blacklist if a message’s IP address is listed. Other anti-spam events included in the log file are:
Enabling/disabling phrase filtering or content filtering
Initialization of phrase filtering and content filtering for each message
Verification checks performed on a message and the results
Connections to realtime blacklists and the results of the connection
File Format
The file format for anti-spam log lines is similar to that of the IMail Server logs, except that anti-spam log messages also contain an anti-spam message ID. The generic format of a log file entry is:
Date - Time - Anti-Spam Message ID -Thread or Process ID - Host name – Entry
Type - Message
Example:
File Format for Premium Anti-spam Log Entries
10:17 11:24 SMTP(f593012a00000001) e-mail determined to be spam by Premium filter, Tag =
5AE906968DC04881B0626ADBF612D86F, where Tag is the signature ID of the e-mail that caused the spam.
Thread ID
The thread ID allows you to identify all log entries for specific messages. For example, if you want to identify all log entries for the above example, you would look for every entry that contains the thread ID of (00001316). The thread ID persists across log files so you can find a thread ID in the anti-spam log and trace the same message in the SMTP log. This is also the same ID that is used to create the Q and D filenames when a message is being processed.
342
IMail v12 Administrator Help
In addition, the thread ID is inserted into the message's X-Header when it is identified as spam.

Log Message Components
Anti-spam log lines contain all or some of the following components.
All log messages are proceeded by the following line: month:day hour:minute app_name(connection_ID)
Most log messages also have the following line:

Spam X-Header Explanations
When an e-mail message matches a realtime blacklist, included on the Connection Checks page under the Antispam > [select a domain ] > Spam Filtering > Connections Checks, an
X-Header line is automatically inserted into the message header to indicate the blacklist that the message matched.
X-Headers are also inserted when a message fails one of the verification checks set in the
Verification Checks options on the Connection Checks page.
All other spam features can be configured to insert X-Headers. These X-Headers indicate the spam filter that trapped the message and information about why the message was trapped.
Additionally, the message ID is inserted into the message's X-Header when it is identified as spam. See the examples and a table of all anti-spam X-Headers below.

Antispamseeder Utility
Overview (antispamseeder.exe)
The antispamseeder.exe utility, located in the IMail top directory, is used to manage the spam and non-spam word counts contained in the antispam-table.txt file. You can use this utility to modify the antispam-table.txt file in the following ways:
Re-assign the word counts contained in the antispam-table.txt
file, when e-mail is incorrectly identified as spam (false positive), or vice versa. This increases the likelihood that such messages will be correctly identified in the future.
Create a new antispam-table.txt file that applies only to a specific host.
Add new words to the antispam-table.txt
file.
Delete words from the antispam-table.txt
file that do not occur very often to decrease the size of the file.
Enter wildcards (i.e. g* *d) into the antispam-table.txt
file so that statistical filtering will identify such words as spam. either need to copy antispamseeder.exe to the secondary host’s directory, or access antispamseeder.exe from the primary IMail domain's directory.

Preparing Mailboxes for use with antispamseeder.exe
Before a mailbox can be used by antispamseeder to create or alter the antispam-table.exe
file, several precautions should be taken.
Mailboxes Messages should be Alike
Make sure that each mailbox contains the same type of e-mail messages. For example, one mailbox should contain only spam messages, and another mailbox should contain only non-spam messages.
Mailboxes should be the Same Size
Make sure that all mailboxes contain relatively the same number of e-mail messages. If one mailbox contains substantially more e-mail messages than the other, the word counts will be skewed and content filtering may not function correctly.
Remove Extra Text
You need to clean up all forwarded e-mail messages. Sometimes, a mailbox contains messages that were forwarded by a user (for example, the message was misidentified as spam or should have been identified as spam and the user wants it added to the good word counts). If this is the case, you will need to examine each forwarded e-mail and remove any information that was not included in the original e-mail, before using the mailbox with antispamseeder.exe. Information that needs to be removed is anything that was inserted by the user’s e-mail client when the message was forwarded, such as the following:
Message headers (i.e. To, From, CC , Date, Subject)
Original message indicators ">"
Anything that the user inserted into the e-mail including signatures, business cards and comments (for example, "This message was incorrectly identified as spam").
Failure to remove the above items may result in a inaccurate antispam-table.txt file, which will cause statistical filtering to incorrectly identify spam.
Antispamseeder Parameters
The following parameters can be placed in any order within a command.
355
IMail v12 Administrator Help
Command
-c<word count>
-e<exclude.txt>
-good
-h<hostname>
-l
-lo
-m
-spam
-t<antispam-table.txt>
-w<word>
Function
Represents the spam count or non-spam count of a word. This can also represent the total number of times the word has occurred in all e-mail messages.
Prevents a domain from being added to the URL Domain lack List. Used when you are importing a mailbox into the URL Domain Blacklist that contains domain names that are not spam.
Identifies the word or mailbox entered as non-spam.
Represents the name of the host.
Adds a mailbox or domain to the URL Domain Blacklist, and updates the antispam-table.txt file. -l can only be used with the spam parameter, not the good.
Use this parameter to update only the URL Domain Blacklist.
The mailbox name or path.
Identifies the word or mailbox entered as spam.
Identifies the antispam-table.txt file that will be merged with the specified host's antispam-table.txt file. Words that exist in the specified anti-spam table, but not in the specified host's anti-spam table, are added to the specified host's anti-spam table.
Represents a word. This is used in conjunction with -c to set the spam or non- spam count of a word within the antispam-table.txt file. It is also used in conjunction with -x to delete a word from the antispam-table.txt file.
-x Deletes the word specified by the -w parameter from the antispam-table.txt file.
Identifying spam with double byte characters
Some spam contains multi-byte character sets that are not read by IMail. One way to treat all these multi-byte words as spam is to add words of all dashes to the word file. The word file contains words ranging from 4 to 15 characters in length, so you can add a word of each length like this: antispamseeder -spam –w- - - - -c100 -hdomain.com
antispamseeder -spam –w- - - - - -c100 -hdomain.com antispamseeder -spam –w- - - - - - -c100 -hdomain.com
Merging Antispam-table.txt files
You can use the antispamseeder.exe utility to merge two antispam-table.txt
files. This is useful when you have modified your antispam-table.txt
file, but you want to download the latest updated file from the Ipswitch Web site. It is also useful for combining the antispam-table.txt
files of several domains. Using the procedure below, you can retain your customizations while gaining new statistical information from more recent spam.
356
IMail v12 Administrator Help
To merge two antispam-table.txt files:
1 Identify which antispam-table.txt files you want to merge.
2 Merge the two files by entering the following command in the command prompt substituting the hostname with the name of your mail host, and substituting antispam-table.txt
with the name of the anti-spam table that you want to merge with that of the specified host: antispamseeder.exe –t<antispam-table.txt> - h<hostname>
Note:
antispam-table2.txt
). This is only necessary if you want both files to reside in the same directory. The antispam-table.txt
files should be placed in the same directory as antispamseeder.exe. If they are in separate directories, you must enter the full path name for the files.
Example:
C:\Program Files\Ipswitch\Collaboration Suite\IMail\Host2\antispam-table.txt.
What happens when you run this command?
First, antispamseeder reads the specified antispam-table.txt file, and compares it to the antispam-table.txt
file for the specified host. Then, words that are not listed in the host’s file are added to it. Since the spam and non-spam word counts for each antispam-table.txt
file are different, the antispamseeder utility will recalculate the counts for each word that is added to preserve accurate statistics for the word. Therefore, new words are added with the existing word counts, and existing words are recalculated to balance the two files word counts.

Deleting Words from Antispam-table.txt
You can use antispamseeder.exe to delete words, from a host’s antispam-table.txt
file, that occur infrequently. You may want to delete these words to save space and improve content filtering processing efficiency. This command works by eliminating all words that have occurred less than the number of times specified. For more information, see
Understanding the antispam-table.txt File (on page 447) to determine whether words should
be deleted from the Antispam-table.txt file.
To Delete Words from Antispam-table.txt File:
1 Open the antispam-table.txt file, located in the host’s directory.
2 From the command prompt, enter the following command: antispamseeder.exe -x –c<total word count> - h<hostname>
3 The words that have occurred fewer times than the total word count entered in the command are removed from the antispam-table.txt file.
Example
If you want to remove all words from the antispam-table.txt file that have occurred fewer than five times in all e-mail messages, enter the following command, where "Host1" is the name of the host:
358
IMail v12 Administrator Help
antispamseeder.exe –x –c5 -hHost1
After running the above command, and reopening the antispam-table.txt file, notice that all words that had previously occurred less than five times are gone.
Parameter
- c<word count>
Function
Represents the spam count or non-spam count of the word. This can also represent the total number of times the word has occurred in all e-mail messages.
- h<hostname> Represents the name of the host.
-x Deletes a word from the antispam- table.txt file.

Resolving Incorrectly Identified E-mail
When IMail Server incorrectly identifies a mail message (false positive), you can use antispamseeder.exe to add statistical information about the e-mail into the antispam-table.txt file to rebalance the spam and non-spam word counts. This will increase the likelihood that similar e-mail messages will be correctly identified in the future.
To change the word tables to recognize messages that are incorrectly identified as spam (or vice versa):
If you have a significant number of messages that are incorrectly identified as spam, you can place the messages in a mailbox and add the entire contents of the mailbox to the antispam-table.txt file at once. The following procedure explains what to do when legitimate messages have been identified as spam:
1 Place all of the incorrectly identified e-mail (non-spam) in a single mailbox. Make sure that this mailbox contains only non-spam.
2 Create the non-spam word counts within the file by entering the following command in the command prompt substituting the hostname and mailbox with your host name and mailbox name that contains the incorrectly identified (non-spam) messages:
antispamseeder.exe –good –h<hostname> –m<mailbox (on page 367)>
3 The antispam-table.txt in the host’s directory is now updated with the new word counts.

Creating Separate antispam-table.txt Files for Multiple E-mail
Domains
There may be occasions where a current e-mail domain (IP-ed domain) does not want to use the primary e-mail domain's (IP-ed domain) antispam- table.txt
file because administrators for each domain do not agree on the words to use for spam. Or perhaps, the administrator for the primary domain is not satisfied with the
antispam-table.txt
file that
ships with the product (Example (on page 368)). In these cases, the antispam-table.txt file can
be altered.
To create spam and non-spam word counts for an e-mail domain:
Use the contents of the antispam-table-ini.txt
file. This file includes word counts that are created during installation. This file contains the initial word counts; however, it does not contain changes that were made by the primary e-mail domain.
Use the antispamseeder.exe utility to create new word counts in the antispam-table.txt file for the e-mail domain. This option is used to take the above option a step further to customize the word counts specific to the secondary (current) e-mail domain.
To create a new antispam-table.txt file:
antispam-table.txt
file, you must delete it before selecting the Current Domain option as shown in the following instructions. If you do not delete it, the antispam-table.txt file will not be copied to the directory and the word counts will not be updated. You can also backup this file to another location in case you decide to revert to it later.

Creating URL Domain Blacklist with antispamseeder.exe
The easiest method to create a URL Domain Blacklist is to use the antispamseeder.exe utility.
Antispamseeder will extract the domain names from the HTML code of collected spam messages. The procedure for doing this is described below.
Creating/Updating the URL Domain Blacklist Using Antispamseeder
Enter the following command:
Antispamseeder.exe –lo -e<exclude> –h<hostname> - m<mailbox (on page 367)>
Where:
Exclude represents the Exclude file.
Hostname is the hostname of the host for which you are updating the antispam-table.txt file and the URL Domain Blacklist.
Mailbox is the mailbox that contains the spam messages that you want to use to create the URL Domain links list, and the word counts for the antispam-table.txt file.
Note that the mailbox must contain only spam messages, because all domain names in the URL Domain Blacklist are considered spam domains.
Example:
Suppose you have a host named "Host1", and want to update the URL Domain Blacklist using the messages in a mailbox called "spam". You have also created an exclude file called excludedomains.txt. Enter the following command: antispamseeder.exe –lo -eexcludedomains.txt –hHost1 –mC:\Program
Files\Ipswitch\Collaboration Suite\IMail\Host1\Users\root\spam.mbx
What happens when I run this command?
Antispamseeder examines each message in the "spam" mailbox for HTML code, specifically
HREF and IMG SRC tags. When one of these tags is found, the primary domain name is extracted from it and added to the URL Domain Blacklist. The new URL domain names will appear under the Realtime Blacklists on the Anti-spam tab > Connection Checks.
364
IMail v12 Administrator Help
Notes:
If a domain name is preceded by www, this section is dropped when the domain name is added to the URL Domain Link list by antispamseeder.
We recommend that you add your domain name to the exclude file. Unless you are certain that a domain name does not exist in the mailbox you are using with antispamseeder, you should include the –e<exclude> parameter every time you run a mailbox through antispamseeder with the –l or –lo parameter.
A list of words that are not included to determine whether a message is spam. The words in the exclude list are words that have an equal chance of being non-spam as spam. For example, "Mortgage" is a term frequently used in spam. However, if you work in the financial industry, this term may appear frequently as non-spam. In such a case, you can enter the word "mortgage" into the exclude list. The exclude list should also include common words like proper names. The exclude list is stored in the exclude-list.txt
file located in the mail domain 's directory.
How do I know which domains to enter?
You should begin collecting spam in a mailbox or use a spam mailbox that you already have.
Since most spam contains URL links, you can use these messages to update the URL Domain
Blacklist with antispamseeder.

Using Antispamseeder.exe to identify wildcards
When IMail Server scans an e-mail, it breaks the e-mail down into the individual words. Each character in each word is then checked to make sure it is a valid character. By default, IMail
Server does not recognize non-alphabetic characters (except hyphens) or numbers. When comparing words to the antispam-table.txt file, non-alphabetic characters and numbers in a word are treated as the "-" character. So if the word "2Sexy" is found in an e-mail, it is treated as "–sexy" when it is compared to the antispam- table.txt file.
If you want IMail Server to identify such words as spam or non-spam, you must enter them into the antispam-table.txt file using antispamseeder.exe.
To identify words with non-alphabetic characters or numbers as spam or non-spam:
1 From the command prompt, enter the following command:
antispamseeder.exe –w<word (on page 367)> –c<word count (on page 368)> [-
spam|-good] -h<hostname>
2 The word that you entered in the above command will be identified as either spam or non-spam, depending on which parameter you entered.
Examples:
Parameters
Parameter
-c<word count>
- h<hostname>
- w<word>
-spam
Function
Represents the spam count or non-spam count of a word. This can also represent the total number of times the word has occurred in all e-mail messages.
Represents the name of a host.
Represents a word. This is used in conjunction with -c to set the spam or non- spam count of a word within the antispam-table.txt file.
Identifies the word entered as spam.

Understanding the Antispam-table.txt File (on page 447)
Using the antispam-table.txt File
The antispam-table.txt
file is the file that contains the spam and non-spam word counts for use with the content filtering feature in IMail Server. When new versions of IMail Server are released, this file is updated to reflect better word statistics.
This installation wizard dialog lets you decide whether to overwrite this file:
Merge. Adds new words to the current antispam-table.txt
file.
Overwrite. Replaces the current antispam-table.txt
file with the updated file.
Ignore. Does not install the updated word counts.
Note:
antispam-table-ini.txt
file into your current antispam-table.txt file after installation, using the antispamseeder.exe
utility. For more information, see the Antispamseeder.exe Overview (on
Modify Subject for URL Domain Blacklist
By default, the text that is added to the message subject is:
X-IMail-Spam-URL-DBL
Mailbox Path
If the mailbox resides in the same directory as antispamseeder.exe, enter the name of the mailbox (.mbx) that contains the messages that you want to add to the antispam-table.txt
file. If the mailbox does not reside in the same directory as antispamseeder.exe, enter the full path of the mailbox.
Word (defined for the antispam-table.txt file)
Any word you want to add to the antispam-table.txt file must comply with the following rules:
It must be between 3 and 32 characters.
It cannot contain any non-alphabetic characters except a hyphen.

Do I need to alter the word tables in the antispam-table.txt file?
The antispam-table.txt file that ships with the product, is appropriate for most users.
However, you may need to alter this file if we have identified words as spam that you do not consider to be spam, or vice versa. For example, the word "mortgage" is identified as spam because in our tests, it occurred 370 times in non-spam, and 714 times in spam. However, at financial institutions, the word "mortgage" is a non-spam word that occurs frequently. In this case, you need to alter the antispam-table.txt file so that the antispam engine recognizes the word "mortgage" as non-spam.
Changing the Word Count for a Word (Example)
If you want to alter the entry for the word "graciously" in the antispam-table.txt file so it is treated as spam , enter the following command (where 10 is the word count that you want to assign to the word "graciously", "Host1" is the hostname, and "graciously" is the word).
In essence, you are altering the entry for the word "graciously" in the antispam-table.txt file, therefore increasing the likelihood that this word will be identified as spam in future e-mails.
Before running the above command, the entry for this word looked like this in the antispam-table.txt file: graciously,583326,14,2
After running the above command, the entry looks like this in the antispam-table.t
xt
file: graciously,583326,14,10
Word count
The word count you want to assign to a word. For example, suppose you enter the following command:
-wstart -c10 -spam -hHost1
The word "start" is now treated as if it has appeared in 10 spam messages.

Troubleshooting
Troubleshooting Anti-spam
Spam is not being redirected to the mailbox entered in the "Forward
To" field
By default, spam is sent to "root-bulk". Root-bulk is a sub-mailbox that did not previously exist on your system. If the host has the Sub-mailbox Creation option set to Bounce or Send to
Inbox, then the spam is redirected. See Setting Domain Properties (on page 42) for
information on how to change the sub-mailbox option.
My Max Mailbox size has been exceeded
If you choose to forward spam messages to a mailbox and receive a large quantity of spam, it is possible that the max mailbox size defined for the mail domain (host) has been exceeded.
To remedy this, either delete some of the spam from the mailbox or increase the max mailbox size. To ensure that you are notified of this situation in the future, you may want to set up a
Full Mailbox Notify Address, so that you will receive an e-mail when the mailbox is near
capacity. For more information, see Setting Domain Properties (on page 42).
I am still getting spam
It is not possible for IMail Server to eliminate all spam. It is inevitable that a small percentage will still get through to your mailbox. However, you can adjust the Advanced Statistical filtering options to increase the performance of IMail Server’s antispam component.
There are no blacklists available for the host
If there are no blacklists displayed on a host’s Add Realtime Blacklist list, that means no blacklists are enabled at the server level. See Setting Connection Checks Options (Domain Level
Options) (on page 333) for information on how to enable realtime blacklists for the server.
IMail Server is running extremely slow
If you have enabled any of the verification options, this could cause a slowdown. See Setting
Connection Checks Options (on page 333) for more information on the verification options.
Spam is not being sent to the correct mailbox
Make sure that the mailbox you want spam sent to is entered in the Forward to Address
field on the Phrase Filter Options page (on page 303) and the Statistical Filter Options page (on
page 316). If the correct mailbox is displayed, check to see if the host has an inbound delivery
rule (on page 246) that may be trapping the message and sending it to a different mailbox.
Legitimate e-mail is being identified as spam (false positives)
There are several reasons why a legitimate message may be identified as spam. First, make sure that the IP address is not listed in a blacklist. Do this by examining the message header for the "X-IMAIL-SPAM:" line. Second, see if the message failed any verification checks.
369
IMail v12 Administrator Help
Sometimes, even legitimate SMTP servers have wrong DNS records. If the message is identified as spam by content filtering, you need to use the antispamseeder.exe utility to alter
the antispam- table.txt file (on page 354).
Some of my users cannot send outgoing mail
To assume your users' mail is delivered, enter your mail server’s domain name into the trusted addresses list.
I have setup a "Spam" mailbox that all spam messages are sent to, but some of my users cannot see this mailbox. Why?
The "spam" sub-mailbox is not created until the user account receives spam, so it is possible that the account has not received any spam. If the users are POP3 users, they will not see the
"spam" mailbox unless they login using the format userid-spam.
Minimizing False Positives
What is a False Positive?
As with any spam product, there is a chance that IMail Server may identify non-spam messages as spam. Such mistakes are called false positives. False positives can occur in both
connection and content filtering. Example (on page 302)
Why Do False Positives Occur?
False positives resulting from content filtering may include newsletters and other various types of e-mail that people subscribe to. Many of these get caught by the content filters because they may contain ads that look like spam.
How to Prevent False Positives
The following methods are effective in minimizing false positives:
White List (trusted addresses) (on page 267). Add the IP address (or range of addresses),
domain names, and e-mail addresses for your network to the trusted address list. Any e-mail received from an IP address in this list will not have connection or content filtering performed on it.
Delivery Rules. Set up delivery rules (on page 245) to send spam to a sub-mailbox in
each user's directory. To do this, configure connection filtering (on page 333) and
content filtering (Phrase Filter (on page 303) and the Statistical Filter (on page 316)) to
place X-headers in the message. Then, create a domain rule that searches for a header that contains X- IMAIL-SPAM to place the message in a sub-mailbox (i.e.
H~X-IMAIL-SPAM:spam). Users can then make individual rules that move messages back into the main mailbox.

IMail v12 Administrator Help
Identifying spam with double byte characters
Some spam contains multi-byte character sets that are not read by IMail. One way to treat all these multi-byte words as spam is to add words of all dashes to the word file. The word file contains words ranging from 4 to 15 characters in length, so you can add a word of each length like this: antispamseeder -spam –w- - - - -c100 -hdomain.com
antispamseeder -spam –w- - - - - -c100 -hdomain.com antispamseeder -spam –w- - - - - - -c100 -hdomain.com
Pager Problems
Most problems with pager communications seem to be caused by modem initialization strings. The modem must have the "interface to modem" and "modem to distant end" set to the same baud rate, either 300 or 1200 baud. The modem must have "echo" disabled,
"command textual responses" enabled, must return standard Hayes compatible responses, and must accept Hayes compatible commands. The system must be tested at 300 baud.
Once, you've established that the pager works, you can change the baud rate. Modems that return connection information other than "Connect ..." must have the extra connect information turned off. Modems that lock interface speeds must have that option disabled or locked to the desired connect speed (300 baud).

The Public Folders page allows you to manage public access and sharing in Calendar,
Contacts, Mail, Notes, and Tasks. It allows you to add (create), update, delete, or view public folders. Public folders are folders that are made available to selected users and groups, and are an effective way to collect, organize, and share information with other people. You can use them to store items, such as calendars, contacts, tasks, etc., which are shared by two or more people.
Note: Web client will only display shared contacts and calendars.
A useful example of a public folder is a public contacts folder, where all specified staff will have access to the organization- wide list of contacts. Another example is a public calendar, which lets all staff know when a meeting room is available or in use. When you create a public folder and give, minimally, read access to a user, the folder will appear in the user's calendaring tool the next time they synchronize.

POP3 / IMAP - Control Access (on page 405)
Creating Public Mailboxes
The IMAP4 server options provide a means of creating a public mailbox in which you can post
messages for reading by IMAP4 clients. To create a public mailbox, create a user (on page 166)
ID named "public". Any mailboxes in this user's directory will be available for reading by
IMAP4 clients.
Administrators can use the public user ID to post messages. Users other than public can only read the public mailboxes. Administrators can set an option that determines whether users must subscribe to a public mailbox before they can read it.
Public mailboxes are read-only by design, and only the user public can administer the public mailboxes. Messages received for this account and its sub-mailboxes are treated as normal, but users other than public who access these mailboxes through IMAP4 have read-only permissions. If a user tries to mark a message in a public folder as read, he will be notified that the mailbox is read-only. subscribe to a mailbox unless the client application provides this capability.
Managing Mailboxes
When a user creates a mailbox, the mailbox is created on the IMail Server system. Because the
IMail Server will be the permanent storage location for IMAP4 users' mail, you need to configure the server with appropriate disk space and manage the disk space by monitoring mailbox disk usage.
You can set maximum mailbox size and maximum number of messages for each user or you can set the maximum mailbox size and maximum number of messages globally for all users on a selected e-mail domain :

For more information about global settings for a selected e-mail domain, see
Changing IMail Standard User Settings (on page 117).
For more information about individual user settings for a selected e-mail domain, see
Changing IMail User File Directory Settings.
Administrators can set an option (on the IMAP4 tab) that determines whether users must subscribe to a private mailbox before they can read it.
LDAP
Short for Lightweight Directory Access Protocol, a set of protocols for accessing information directories. LDAP is based on the standards contained within the X.500 standard, but is significantly simpler. And unlike X.500, LDAP supports TCP/IP, which is necessary for any type of Internet access. Because it's a simpler version of X.500, LDAP is sometimes called X.500-lite.
Because LDAP is an open protocol, applications need not worry about the type of server hosting the directory.
About LDAP Server
Lightweight Directory Access Protocol (LDAP) provides a standard way for applications to request and manage directory information. LDAP has become another popular feature for standards-based mail servers. A simplified subset of the much more elaborate X.500 Directory
Access Protocol, LDAP is more appropriate for many of today's applications, on both the client and server sides, because it makes fewer demands on system resources.
LDAP implementations use a client/server architecture to publish user information (such as address books) on the server and provide access to that directory information from
LDAP-enabled clients.
IMail Server supports OpenLDAP to provide the following capabilities to users with
LDAP-enabled clients:
Locate LDAP directory information that may include name, phone number, e-mail address, organization, department, and address.
List all users at a site.
About LDAP Data
IMail Server provides an LDAP database by extending the IMail user database to include standard LDAP attributes (such as name, address, organization name, and phone number) and any other attributes that a site defines.
Each user with an account on the IMail Server has an LDAP entry. When a user is added to the
IMail user database an LDAP entry is defined with the following attributes:
395
IMail v12 Administrator Help
Basic User Attributes
ObjectClass The type of entry. The value would be "inetOrgPerson".
CN CommonName
UID
Surname
The full name of the user.
The IMail Server e-mail address for the user. This is constructed from the user ID and the host name.
The IMail Server user ID.
The surname or last name of the user.
When a user receives mail on the IMail Server system, his/her LDAP entry is activated.
Using an LDAP enabled client, the user can add, delete, and modify information in his or her own LDAP entry. A user cannot modify another user's entry. The following table describes several additional attributes that the user can add (by using an LDAP client that supports the
Modify function):
Optional User Attributes
Organization
OU
Street
L
ST
C telephoneNumber
The user's company.
The department within the company or organizational unit.
The user's street address.
The user's city or locality.
The user's state or province.
The user's country.
The user's telephone number.
These are the most common attributes used in the LDAP entry. The system administrator or the user can define other attributes. by the LDAP server. Do not click Initialize LDAP unless you want to overwrite the database with the user IDs only that are stored in the Windows registry. First try synchronizing the
LDAP database to resolve any problems.

Queue Manager
The Queue Manager Service allows you to control the flow of messages through the mail queue. This service takes the place of SMTP32.exe, by delivering messages to both local and remote destinations. Although the SMTP32.exe program still exists, it simply informs the
Queue Manager when a message requires delivery.
Note: When sending mail, if a valid 1xx or 2xx response is not received when connecting, the
Queue Manager will roll to the next MX record.
The mail queue is also known as the spool is a directory that stores mail messages that are waiting for delivery. Files in the queue include incoming messages, outgoing messages, attachments, and error messages.

Services from your respective web pages, as well as from the Service Administration page.
The Queue Manager regulates the SMTP32 processes (or threads) so that the maximum number is not exceeded. This ensures that an attempt is made to deliver all messages and that delivery not be delayed by being bumped to a queue run delivery on heavily loaded systems. Files are processed according to priority, with files that have had no delivery attempt being first. Files that need to be retried are then processed based on the time that they were placed in the spool.
Disabling the Queue Manager may stop or delay mail delivery.
Delivery Threads. Enter the total number of delivery threads that can be used to deliver messages. Each thread processes one message at a time. This option is set to
30 by default; its minimum value is 5. Since each Queue Manager thread can deliver one message, if the option is set to 30, the Queue Manager can deliver 30 messages at a time. number of users who subscribe to list server mailing lists. If you do need to increase this value, you should do so in small increments, for, as you increase the number of SMTP processes, you increase the processing load on your mail server.
Max Retry Threads. Enter the maximum number of delivery threads that can be used simultaneously when the system retries to deliver messages in the queue. By default, this option is set to 15. The value for this option must be less than the number of Delivery Threads and cannot be less than 2.

Listen Pipes. Enter the number of pipes that the queue manager opens in order to listen for files being dropped in the queue by other processes. This option is set to 4 by default. The minimum value for this option is 2 and the maximum is 20. The default value should be sufficient for most servers, but can be increased for better performance on busy servers. You must examine the log files to determine if you need to increase this number. If, prior to a queue run, you find log lines that say
"Adding Queue file XXX," this means that the Queue Manager has found files it was not notified of before. In this case, you should increase the number of listen pipes.
Retry Timer. Enter how often, in minutes, the Queue Manager will attempt to re-deliver messages that failed to be delivered on previous queue runs. This option works in conjunction with the Tries Before Return to Sender below. This option is set to 30 minutes by default. The minimum value for this option is 10; the maximum is
120.
Daily Report Address. Enter the e-mail address to which a Daily Count Report (on

Outgoing Helo/Ehlo Host Name. Enter the name you wish to use for outgoing communications with the recipient.
Tries Before Return to Sender. Enter the amount of times that delivery is attempted before returning the mail to the sender. Each time the Retry Timer reaches 0, a deliver attempt is made. We recommend leaving this at the default value of 20.
Example: If the Retry Timer is set to 30 (minutes) and the "Number of Tries" is set to 20
(default), then the message will be returned in about 10 hours. We recommend a value of 20.
Example: If the Retry Timer is set to 30 (minutes), and you want to attempt delivery for up to 3 days, then the "Number of Tries" box should contain 144.
Max Tries for NULL Senders. Enter the maximum number of times that IMail attempts to deliver a message that has no sender (including postmaster messages).
This value must be less than the value entered for Tries Before Return to Sender above. If the Tries Before Return to Sender value is less than the value entered here, the Max Tries for NULL Senders option is not enforced.

Troubleshooting the Spool Directory
Normally, IMail Server cleans up the .tmp and attached files as part of the delivery process.
However, if there is an SMTP failure during delivery, these files may not be deleted. You can
also run the Spool Cleaner utility (on page 114) (isplcln.exe) to delete old files.
A damaged or corrupt file in the queue can prevent mail from being received correctly. If you suspect that this is the cause of a problem you have, you can try moving all files from the
Spool directory to a temporary location (such as IMAIL\SPOOL\SAVE) and then see if you can

The SMTP service processes all incoming and outgoing messages. Outgoing mail is spooled until the SMTP server can confirm it has arrived at its destination. Incoming mail is spooled until users access it using POP3 or IMAP client. Spooling allows the transfer from client and server to occur in the background.

The SMTP Service processes all incoming and outgoing messages. Due to its openness, it is difficult to simultaneously block unwanted mail (spam) and keep your mail server available to its users. The following settings and options can be configured to help administer this protocol.
Important: After making changes, click Save, and restart the service.
General Options
Mail Relay Settings. Select one of the following from the drop down list:
No Mail Relay (Default setting). Selecting this option from the drop down list enables the SMTP server to refuse to accept mail destined for other hosts (any host not on the IMail Server), unless the user authenticates. Select this option if all of your users send and receive mail from the same host that IMail Server is on, or if they use web messaging to access mail. You will still receive mail for local users because a message destined for or originating from the IMail Server host does not use the relay function.
Relay Mail for Addresses. Select this option from the drop down list to allow the
SMTP server to transmit mail originating from local addresses and destined for other hosts. Likewise, the server will accept mail from other hosts that is destined for specified local addresses.
Addresses. This button is enabled when Relay Mail for Addresses is selected.
Click the Addresses button. The Relay Mail for Addresses (on page 419) page
appears.
Important: DomainKeys / DKIM Signature Verification will not be processed when an
address exists in the "Relay Mail for Addresses (on page 413)".
Relay for Local Users Only. Select this option from the drop down list to check the
"From" address of incoming mail and verify that it contains a valid IMail Server host name, then checks the host for the user ID. accept the named remote hosts and users as "local" hosts and users. If a user needs to use an alias for his/her e-mail address, the alias needs to be in the accept.txt file. You cannot use this option if you are using a "store and forward" setup to relay mail for another server. The accept.txt file is only used when the SMTP Relay Setting is set to Relay for Local.
Relay for Local Hosts Only. Select this option from the drop down list to check the
"From" address of incoming mail to determine that it contains a valid IMail Server host name, then checks that host for the user ID. It does not check user aliases. If the host name or User ID is not valid, the server does not relay mail.

accept the named remote hosts and users as "local" hosts and users. If a user needs to use an alias for their e-mail address, the alias needs to be in the accept.txt file. You cannot use this option if you are using a "store and forward" setup to relay mail for another server. the accept.txt file is only used when the SMTP Relay Setting is set to Relay for Local.
Relay Mail for Anyone. Select this option from the drop down list to allow the SMTP server to accept mail from any host that is destined for any other host, and redeliver that mail (i.e. become a mail gateway). This option is the least secure because it allows your server to be used by anyone to send mail to anyone. Some bulk mailers may take advantage of this capability to not only relay mail through your server, but to make it appear as if mail is originating from your server.

Security Options
Copy to Mail Address. Enter the full e-mail address to which you want to send a copy of each message. This option will not function unless the Enable Copy All Mail check box is selected.
Enable Copy All Mail. Select this check box to enable copying of all mail.
Allow Remote Mail to Local Groups. Select this check box to allow the SMTP server to accept mail addressed to a group that has been defined using IMail Administrator.
The SMTP server re-sends the message to users in the group. Use this option to set access to local mail groups (Local groups are aliases of type Group) on the mail server.
Note: This option does not affect list-server mailing lists, standard aliases, or program aliases.
Check Valid Sender. Select this check box to require that the user's mail address
(user@host) is specified in the MAIL FROM or REPLY-TO line of an incoming mail message.
Auto Deny Possible Hack Attempts. (Set by default) When checked it will assume that sending more than 512 characters in a command other than the SMTP DATA command is an attempt to "hack" into your server. The remote IP address will be temporarily placed into the "deny access" (Control Access) file, until the services are restarted.

Disable SMTP "VRFY" Command. Select this check box to deny a remote host to test for valid user IDs. The SMTP VRFY command is used to verify a user ID on a host, and as such it can be used from a remote host to test for valid user IDs. Disabling the command helps prevent "spoofing" by not allowing someone outside your network to check if a user ID is valid.
If you select this option when IMail Server receives an SMTP VRFY request, it returns the message:
502 Command not implemented.
If you disable the SMTP VRFY command, when IMail Server receives an SMTP VRFY request, it will return the message: 502 Command not implemented needs to use this command to verify a user that is on the other peer. See Setting Up Peering
(on page 271) for more information.
Require CRAM-MD5 Authentication. This setting when set will force encryption authentication when logging in to SMTP services.
Note: CRAM-MD5 Authentication only functions when using an IMail User Database.
CRAM-MD5 Authentication is currently not supported for user databases with Active
Directory or ODBC.
Advanced Options

Max Recipients Per Message. Enter the maximum number of addresses that can receive a single message. The default is 0.
Note: Max Recipients Per Message option does not apply to authenticated users.
Delay Between Recipients. Sets a delay (Milliseconds), between message recipients, for relayed external mail. This prevents spammers from consuming all of the CPU time. However, the setting slows mail server performance. The default is 0.

IMail v12 Administrator Help
Host Delimiters. To change the default characters, enter the character(s) to use to delimit the host name. Each character is seen by IMail Server as equivalent to the @ in e-mail addresses. Any of the defaults can be used between the user ID and the virtual host name in the POP3 or IMAP4 login user ID. By default, the characters used are: @
% * : $ and &.
Important: Be sure to restart IIS (host delimiters are cached for web services), SMTP, and
Queue Manager Services.
Mailbox Delimiter. Enter the character that will be used to delimit the mailbox name in a user ID. If nothing is entered, the default delimiter is - (dash).
Max Connections. Enter the maximum number of connections handled by the SMTP
Service. Use the default of 0 (zero) for an unlimited number of connections.
Port. Enter the port that the SMTP service listens on. The default SMTP port is 25. The valid range is from 0-32000.
Hello Message. To change the SMTP service welcome message, enter the new message in this text box. The text is limited to 400 characters or less. If over 400 characters are entered, the default message is used. To revert to the default message, delete the custom message text from the Hello Message box.

Disable SMTP AUTH. Select this check box to disable SMTP authentication. SMTP
Auth provides a means of authenticating the user ID and password of a user sending mail. This is handled transparently by the mail server and client. When the mail client connects to the mail server, the server tells the client the authorization methods it can use. The client then sends the user ID and password to the server and the server verifies them. If a user issues the AUTH command when Disable SMTP AUTH is selected, SMTPD responds with the "502 command not implemented" message.

Adding Aliases using "addalias.exe" Utility
Addalias.exe is a utility for adding, modifying, and deleting batches of e-mail aliases stored in a text file. You can also import an existing Windows NT group into IMail and create a group alias. If you invoke Addalias.exe with no command line options (by entering only addalias
at the MS-DOS prompt), you can manually input command lines, then press Enter after each line. Make sure that you press CTRL-Z to exit the utility when you are done. Example (on
Basic Command Syntax
addalias [-h hostname] [-cX] [-{a|d|m}] alias [=destination]
435
IMail v12 Administrator Help
Command Function
-a aliasname Adds an alias if the alias does not exist. aliasname is the name of the alias you want to add. Only one alias may be added in a single command line.
-cX Specifies an alternate delimiting character, which replaces the default delimiter (the equal sign). Spaces are not allowed. (Using -c in a text file affects all lines in the file.)
-d aliasname Deletes an alias that already exists, where aliasname is the alias you want to delete.
Only one alias may be deleted in a single command line.
-f filename You can put multiple commands into a text file for one execution of Addalias. Use -f to specify the name of the text file containing the Addalias commands. (All the above commands are valid for the text file, but note that -h and -c persist across multiple lines of input.)
-h hostname Specifies the virtual domain for the alias. The primary domain is used if no e-mail domain is specified. (Using -h in a text file affects all lines in the file.)
-i groupname Imports an NT group as a group alias if the alias does not already exist. groupname is the group that you want to import. Only one alias can be added in a single command line.
-l Lists current aliases. This argument may not be used in a text file.
-m aliasname Modifies or adds an alias even if the alias exists. aliasname is the alias you want to modify. Only one alias may be modified in a single command line.
-? Displays a summary of argument options.
Addalias.exe Examples
Adding an Alias to the Default (primary) E-mail Domain (on page 214)
Adding an Alias to a Specific Domain (on page 213)
Deleting an Alias (on page 214)
Importing an NT Group as a Group Alias (on page 438)
Return codes
Addalias.exe returns 1 if it performed at least one of the requested operations; it returns 0 if it failed.
Using a Text File
Instead of entering commands at the MS-DOS prompt, you can use a text file to input multiple commands for one execution. You can use this technique to add aliases to IMail
Server from another mail system if the other mail server program can create a delimited text
file of aliases. Example (on page 215)
Adding Alias to a Domain Using "addalias.exe"
Adding an Alias to a Specific Domain Using the addaliase.exe Utility

Import NT Group as Group Alias using addalias.exe
This option is only for hosts using the Windows NT database. Global groups will be ignored if the server is not a Primary Domain Controller (PDC).
The following example takes an existing Windows NT group and converts it into an IMail group alias: addalias -h NThost.com -i groupname
Adding a Virtual Host (adddomain.exe)
AddDomain.exe is a utility for adding virtual domains. It can be used to simply add a single domain, but is especially useful in a batch file to add multiple domains.
Basic Command Syntax and Example
Usage:
adddomain -h Hostname -i IPAddress -t TopDir
[-a Aliases -u IM | NT | External -x MaxMBXSize -s MaxMBXMsgs -r MaxUsers] adddomain -h Hostname -m
438
IMail v12 Administrator Help
[-t TopDir -a Aliases -x MaxMBXSize -s MaxMBXMsgs -r MaxUsers] adddomain -h Hostname -i IPAddress -t TopDir -u External
[-e DLLFilename -o ODBC_DSN -n TableName] adddomain -h Hostname -delete adddomain -f Filename
Examples:
1 In the following example, since the -e, -o,or -n options are not specified, the external database relies on the default “values %“Imail_top dir”%odbcuser.dll , IMAILSECDB, and
[default] accordingly: adddomain -h newhost1 -i virtual -u external
2 The following command populates an external database with settings of C:\mydll.dll,
IMAILSECDB, and [default]: adddomain -h newhost2 -i virtual -u external -e C:\mydll.dll
3 The following example changes an existing host (notice the -m for modify) to use an
ODBC Data Source Name (DSN) of MyNewDSN. If the other fields of -e and -n were previously set, they will be preserved. If the other fields of -e and -n were not previously set, they will be set with the default values: adddomain -h ExistingHost -m -u external -o MyNewDSN
4 If you need to specify a DSN other than ‘IMailSecDB,’ or you need to specify a userID and password (required when setting up a DSN to connect to an SQL database), use the -o switch : adddomain -h ExistingHost -m -u external -o IMailSecDB;UID=MyUser;
PWD=MyPassword
5 The following example shows how to add a new virtual host (or virtual host with an IP ) using an external database: adddomain -u external -t C:\IMail\newdomain_com -i virtual
-o IMailSecDB;UID=sqluser;PWD=sqlpassword -n table_name
6 Adddomain.exe supports the following command line options:
Command Function
-h
-i

Using a Text File (adduser.exe)
Instead of entering commands at the MS-DOS prompt, you can use a text file to input multiple commands for one execution of adduser.exe. You can use this technique to add users to your IMail system from another mail system if the other mail program can create a delimited text file of user ids, passwords, and user names.
Let’s suppose you want to add four user IDs (userid, smith, test1, and jones) to the wks013 server . Adduser.exe assumes that if there are no arguments in a text file, then the information on each line is userid, password, and full name – in that order.
For example, you could create a text file named addfour.txt that contains the following lines: userid,password,full name
444
IMail v12 Administrator Help
smith,whypass,Mrs Smith test1,,Mr Smith jones,okpass,Tom Jones
At the MS-DOS prompt, you enter:
Adduser -h wks013.augusta.ipswitch.com -f addfour.txt
You then get the following messages: current host is wks013.augusta.ipswitch.com
OK: added userid to host wks013.augusta.ipswitch.com
OK: added smith to host wks013.augusta.ipswitch.com
OK: added test1 to host wks013.augusta.ipswitch.com
OK: added jones to host wks013.augusta.ipswitch.com
Note that the user named test1 will have "password" (the default) as his password.
Rename a User (RenameUser.exe)

Overview (antispamseeder.exe)
The antispamseeder.exe utility, located in the IMail top directory, is used to manage the spam and non-spam word counts contained in the antispam-table.txt file. You can use this utility to modify the antispam-table.txt file in the following ways:
Re-assign the word counts contained in the antispam-table.txt
file, when e-mail is incorrectly identified as spam (false positive), or vice versa. This increases the likelihood that such messages will be correctly identified in the future.
Create a new antispam-table.txt file that applies only to a specific host.
Add new words to the antispam-table.txt
file.
Delete words from the antispam-table.txt
file that do not occur very often to decrease the size of the file.
Enter wildcards (i.e. g* *d) into the antispam-table.txt
file so that statistical filtering will identify such words as spam. either need to copy antispamseeder.exe to the secondary host’s directory, or access antispamseeder.exe from the primary IMail domain's directory.

Merging Antispam-table.txt Files Example
Suppose that at installation, you chose to store the updated word statistics in the antispam-table-ini.txt
file, and now you want to merge them with your existing antispam-table.txt
file. Assuming that your host is named "Host1", enter the following command: antispamseeder.exe -tantispam-table-ini.txt -hHost1
Understanding the antispam-table.txt file
The antispam-table.txt
file contains the word counts that content filtering uses to determine if a message is spam. Each word is assigned three values. The first value is the statistical value assigned by the antispam engine. The second value is the number of times that the word has occurred in non-spam e-mail messages. The third value is the number of times that the word has occurred in spam e-mail messages.
Note:
antispam-table.txt
file was created using e-mail messages and words that were received at Ipswitch. You may find that the words and values contained in it are not entirely appropriate for your use. In this case you can customize the file based on your needs
by using the antispamseeder.exe utility (on page 354).

Antispamseeder.exe Wildcard Example 2
If you want the antispam engine to identify the word "2Sexy" as spam, add it to the antispam-table.txt file by entering the following command, replacing domain.com with your domain name: antispamseeder.exe -spam -w-sexy -c100 - hdomain.com
This command adds the word "-sexy" to the antispam-table.txt file as if it had occurred 100 times in spam e-mail. The word will now be treated as a spam indicator by the content filters.
If you want the antispam engine to identify the word"g00d" (with zeros) as spam, you must enter the word into the antispam-table.txt file by running the following command, substituting dashes for the non-alphabetic characters. In this example, " host1" is the hostname and "g- -d" is the word you want to be recognized as spam.
Once you run the above command, the antispam engine will recognize any variable of the word "g- -d" as spam, such as g00d, g**d etc. This command does not change the word count for the word "good" because it does not contain any non-alphabetic characters.
Antispamseeder.exe Wildcard Example 1
If you want the antispam engine to identify the word 2Sexy as spam, add it to the antispam-table.txt file by entering the following command, replacing domain.com with your domain name: antispamseeder.exe -spam -w-sexy -c100 - hdomain.com
This command adds the word "-sexy" to the antispam-table.txt file as if it had occurred 100 times in spam e-mail. The word will now be treated as a spam indicator by the content filters.

Importing "config_CommonAddrBook.cgi" to Public
Contact folders
If you used public contacts in a previous version of Ipswitch Web Messaging, the
"config_CommonAddrBook.cgi"
file is no longer functional with the new V12 and later web client. A command line utility has been created to allow the IMail Administrators to import and merge their
"config_CommonAddrBook.cgi"
files into Public Contacts folders using
the IMail Collaboration database.
To successfully import and implement all your public contact
"config_CommonAddrBook.cgi"
files, the following steps are required:
Public Contact Folder Setup
1 Public Contact folders must be created before running this import utility. Go to your
Web Administration and select Collaboration > Public Folders. Click Add when the
Public Folders dialog appears.
2 Enter a unique name for each
"config_CommonAddrBook.cgi"
file. Keep in mind the name entered will be displayed within the Web Client under the user's Address
Books as follows:

IMail v12 Administrator Help
Address Books
Contacts
Department Contacts [Public]
3 Select
"Contacts"
from the Type drop down selection menu and click Save. This will bring up the Public Folder Properties dialog.
4 At this point all users that are required to have access rights must be added at this point.
Click Add.
5 Be sure to leave the Access rights to "Read" only for your normal users. Be sure to click
Save on every page.
Note: The IMail Collaboration database does not currently recognize users on a per domain level, the IMail Administrator will need to manually select all users for each domain, separately for each Public Contacts folder.
6 Next, add full permissions to Administrators to allow maintaining withing the Web
Client. The new public contacts folder will now display for all user's with access rights in their Web Client Address Books navigation folder.
Running "PublicContactsCGI Importer.exe"
1 The
"PublicContactsCGI Importer.exe"
is located under your
"../IMail" directory. Double click to initiate the import process.
2 The main dialog displays all available Public Folders (Calendars, Contacts, Notes and
Tasks).
3 Select (highlight) the Public Contact folder and use the "Browse" button to locate the matching
"config_CommonAddrBook.cgi".
4 Click
"Import"
, upon completion a dialog
"Import Complete"
will return.
Warning: There is no mechanism to avoid duplicate contact entries. Clicking "Import" again, will duplicate all entries.

What is the IMail Web Client?
IMail Web Client lets users send and receive mail using a web browser. Users can log on to
IMail Web Client from a browser on any computer with a supported browser and manage e-mail without installing e-mail client software.
IMail Web Client directly accesses the server to manage mail, and no longer requires IMAP.
After logging in, users can manage e-mail from the browser, organize e-mail into folders
(mailboxes), maintain an address book (contacts) and auto-synchronize it with Microsoft
Outlook contacts (if the IMail Collaboration Client has been installed), and set delivery rules for incoming mail.
When a user creates a mailbox in IMail Web Client, the mailbox is created on the mail server and mail folders and messages reside on the server.

Converting Contacts
If you used contacts or contact lists (distribution lists) in a previous version of Ipswitch Web
Messaging or in Microsoft Outlook with the IMail Collaboration plug-in, the contacts and contact lists are automatically imported into the new IMail Web Messaging client. A new
Contacts folder is created that includes contacts.
Ipswitch Web Messaging contacts and or contact lists (distribution lists) are imported and converted in a one-time process, during the IMail Collaboration installation, that imports the contact data from the aliases.txt file. The new data displays in the Web
Messaging Contacts folder.
Note: Contact lists (distribution lists) imported from a previous version of Ipswitch Web
Messaging are read only. They cannot be edited or added to after they are imported during the Ipswitch IMail Server V12 installation.
