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 Secure Mail Gateway 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:
When processing email messages, Kaspersky Secure Mail Gateway compares the pair of sender-recipient addresses in the message and in rules. Rules are sequentially checked according to their priority, which is indicated by their position in the rules table from top to bottom. 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.
The unique ID of a rule does not indicate the priority of the rule.
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.
For each rule, you can specify your own settings for processing email messages.
