Have you considered running the SpamAssassin Milter?


It's available via EPEL. You can reject high-scoring spam during the 
SMTP transactions. It also allows per-user preferences/Bayes rules to 
run, with the caveat that a message addressed to multiple users can't 
take advantage of the per-user run. (Unlike a setup using mimedefang, 
spamass-milter can't resubmit a message for each addressee.)
