Since it doesn't even directly support postfix, I wouldn't even give it
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.
