If I understand you correctly, 100 or so out of 2000 messages per day
are marked as spam when they shouldn't be?

You haven't said which version of SpamAssassin you're using - that has a
big effect on the scores you get. If you look at the SpamCheck header
and there's a high-value category listed consistently among the wrongly-
marked messages you could lower that score in
MailScanner/etc/spam.assassin.prefs.conf perhaps?

If your correctly marked spam is consistently coming in with higher
scores, then just raise the threshold.

Cheers,

Martin
