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.
