I'd looked into this; we never quite set it up, though.  It can work with
sendmail, postfix, qmail or exim, generally via whichever architecture is
most appropriate for that MTA.  (for instance, with sendmail it uses the
efficient "milter" interface instead of weird multi-queue interfaces,
theoretically making it possible to reject virus-infected email while the
remote end is still sending it to your server)

One *big* caveat, though:
amavis does *not* include a virus scanner.  It's a generalized interface
between several MTAs and many virus scanners, so you need to provide it with
a virus scanner and an MTA, and virus software still tends to cost money.
