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
page 252).
To add a rule with multiple conditions:
1 Follow the instructions to create a rule as described in Setting Inbound Rules for Domains
(on page 246) or Setting Outbound Rules for Domains (on page 247). After adding the first
rule condition, select the new rule condition.
2 Click Add AND/OR... This will bring a pop-up window allowing either

selection of the "AND" button, meaning "ALL" the rule conditions must be met for the message to be trapped.
or selection of the "OR" button, meaning "ANY" one of the conditions must be met for the message to be trapped.
3 Create the second condition as you did the first. Continue adding conditions until you are satisfied with the rule.
4 Follow the instructions to set the rule actions as described in the Actions section of
Adding Inbound Rules for Domains (on page 249) or Adding Outbound Rules for Domains
(on page 249).
5 When you are finished creating the rule, click Add to save your changes.
Rule with Multiple Conditions Example
If you want all e-mails from your supervisor containing information about "project updates" to be sent to a specific mailbox in your account, you would set a rule with two conditions:
1 The message must be from your supervisor; and
2 The message must contain the words "project updates" in the subject or message body of the e-mail.
The rules.ima format:
<BOSS>[email protected]!AND!B~project updates:BOSS
Where:
<BOSS>
[email protected]
!AND!
B~project updates
:BOSS
Rule Name
From Address must contain "[email protected]"
AND means all conditions must be true to be selected
Body of message must contain "project updates"
Mailbox name, that message will be forwarded to of user's account.

How to get here

Attachments are 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.
An attachment blocking folder exists for each e-mail domain and the attachment blocking options can be based on the current e-mail domain or the primary e-mail domain settings.

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"
