Using message processing rules

A message processing rule (hereinafter also "the rule") is a specific multitude of pairs of addresses of senders and recipients whose email messages are processed by Kaspersky Security 8 for Linux Mail Server by applying the same values of settings. For a rule to be assigned to an email message, the addresses of the sender and recipient must be specified in the rule settings.

By default, the program contains the following preset message processing rules:

• WhiteList processes messages from the global white list of addresses.
• BlackList processes messages from the global black list of addresses.
• Default processes messages according to the settings predefined by Kaspersky.

When processing an email message, Kaspersky Security 8 for Linux Mail Server applies rules according to their order in the table from top to bottom, regardless of the sequence number of a rule ID. If the combination of sender-recipient addresses does not match, the program moves on to the next rule. As soon as it finds the sender-recipient pair of addresses in any rule, the program applies the processing settings configured in that rule to the message, and the search for a match is finished.

If none of the rules contains the "sender - recipient" pair of addresses, the message is processed in accordance with the preset settings of the Default rule.

If the message has a DKIM signature, it can be damaged if applied processing rules modify the subject or body of the message, remove attachments, treat malicious objects, or add disclaimers to the body of the message.

For each rule, you can specify your own settings for processing email messages.
