If you can afford using a separate "boundary" SMTP (and, thanks to virtual 
machines, this is much more common than just a few years ago), MailAvenger 
is likely to be a very good solution: for Bayesian filtering it relies on 
plain SpamAssassin, but it really shines in doing deep SMTP transaction 
analysis, ruling out most spam at that level and making it far less CPU 
and memory intensive than its counterparts.

You can find it at http://mailavenger.org/
