SPAM scores
Userdefined SPAM checks
This control allows you to extend the SPAM checks by self-defined rules. First you have
to decide to which part of the mail a new rule applies. If the specified pattern is found
in a mail, the selected score is accounted.
The following types of SPAM filter rules are available:
Subject
The pattern is looked up in the email's subject.
Sender
This will check the sender of the mail (From header).
Recipient
Use this option to match the recipient (To header).
Message header
Allows you to examine an arbitrary mail header.
Message body
The actual contents of the email are analyzed when selecting this value.
Rule
This setting differs from the previous ones. It allows you to modify the score of SX-
GATE's builtin rules. Accordingly you don't specify a search pattern here. Instead
you have to supply the internal ID of the rule. The ID together with the original
score is listed in the content analysis of mails, that have been marked as SPAM
(e.g. "HTML_MESSAGE" or "FORGED_MUA_OUTLOOK").
When the builtin rulesets are updated, internal ID's may
change without notice. The rules defined here will not be
adjusted.
Search patterns ("matches") are case-insensitive. Some characters have a special
meaning:
