In my experience, an anti-virus is left with almost nothing to catch if 
you let spamassassin reject mail above a certain score, and so the AV 
never gets to see those.
However one benefit of delaying AV scanning is that you get later 
signatures, so you could potentially deal better with 0-hour viruses. 
But overall AV is just ineffective.
