We're using AMaViS to virus-scan both inbound and outbound mail.

It works its way down through archives, compression and other
attempts to obscure signatures.  Pretty slick.  Implements as a
mailer in sendmail 8.11.

Only drawback is that it works as a ringmaster, coordinating other
packages to actually manipulate the e-mail and do the scans.  Which
means you have to get a real scanner.  We've been using AntiVirus
from Network Associates (runs under the Linux emulator) with twice
daily automated updates of the signature database, but it will work
with perhaps a half-dozen others.
