Notice the ...SpamCheck: spam, spamhaus-XBL, SpamAssassin...
^ Header ^ ^MS RBL ^SA
Spam/Not spam "status"
After the spam check header, MailScanner is telling you it's classified it
as spam for two reasons:
1. the message was matched against spamhaus-XBL list
2. Spamassassin's score
Note it's an "OR" relationship, not "AND". In other words, if you have
configured RBL's in MailScanner.conf AND MailScanner to use SpamAssassin,
then the first one to identify spam, wins. If neither identify it as spam,
it's considered clean (ham).
If you want to rely on SpamAssassin ONLY, take out the RBL's in
MailScanner.conf. Then your mail will only be identified as spam if
SpamAssassin scores above 5. SA also uses RBL's (many more than
MailScanner in fact) so you wont be "loosing" anything, but you will be
able to adjust the scores of RBL's you trust etc from the
spam.assassin.prefs.conf file, or by custom rules etc.
Just when you thought you were winning the rat race, along comes a
