This is what end up needing to do every 1-1.5 yrs on my mail server.
Take all of your incorrectly flagged email and put it into its own
folder/directory in your email system.
You have some options:
1. Review the score distribution among these emails and determine
which RULE(s) is offending/incorrect. Then reduce either the global
or local setting for that RULE(s). Or change your SPAM required_score
threshold to a higher number.
Example:
3.0 RCVD_IN_XBL RBL: Received via a relay in Spamhaus XBL
2.8 RCVD_HELO_IP_MISMATCH Received: HELO and IP do not match, but should
I think RCVD_IN_XBL should be only 1.0 instead of 3.0, so I modify:
~/.spamassassin/user_prefs
score RCVD_IN_XBL 1.00
You can also add whitelists.
2. Or you can re-sort your spam into 2 folders IS_SPAM (for actual
spam) and IS_HAM (for non spam, actual email) and rebuild the
journals/tokens for them:
# sa-learn --spam ~/mail/IS_SPAM
# sa-learn --ham ~/mail/IS_HAM
Hopefully this will make SpamAssassin relearn the correct matching.
I hope this helps. Read the spamassassin wiki for more ideas.
