MIME headers list Spam filter

You can use the MIME headers list to mark email from certain bulk mail programs or with certain types of content that are common in spam messages. You can choose to mark the email as spam or clear for each header you configure.

The FortiGate unit compares the MIME header key-value pair of incoming email to the list pair in sequence. If a match is found, the corresponding protection profile action is taken. If no match is found, the email is passed on to the next spam filter.

You can use Perl regular expressions or wildcards to add MIME header patterns to the list. See “Using Perl regular expressions” on page 335.

Note: MIME header entries are case sensitive.
