We use postfix/amavisd-new/clamav at several sites, one in particular
that processes about 500,000 incoming e-mail messages a day (after
rejecting about 1,000,000 messages for various reasons).

This server only does the clamav checking for things that attack the
Microsoft virus, Windows, and phishing messages that attack the stupid.
It then passes the messages to one of four Linux boxes which deliver the
mail to NFS mounted Maildir stores, with these boxes doing spamassassin
checking with per-user and per-folder decisions on the spam checking.

The load average in the main server rarely gets about 0.5 even at the
busiest times.

I've been telling people since the early '90s that putting Windows
machines on the Internet is a recipe for disaster, but few listened
(some probably because they make a major part of their income repeatedly
dealing with Windows problems).
