I would second, but add that you also consider looking at Exim if your 
main goal is spam/virus scanning.  The former Exiscan patch is now 
built-in to Exim;  Exim talks directly to spamd and clamd (and a couple 
of commercial AV products), then filters accordingly.

In my experience, its performance far exceeds amavis.

That said, I run Postfix on the servers I manage these days, but I am 
not concerned, now, with protecting Windows users.

Qmail is just too much of a PITA these days to deal with, and its IPv6 
support leaves much to be desired.  I have used it recently, however, 
for a couple of specialized installs on OpenBSD firewalls.
