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/
Since it doesn't even directly support postfix, I wouldn't even give it
a chance.
Personally, my dream antispam system would be ASSP integrated with
amavisd-new running only as an after-queue content filter, and use
postfix's rock-solid built-in pre-queue anti-spam measures.
ASSP's Block Reporting feature is really awesome for end users to manage
anything in their quarantine.
