I've got a mostly FreeBSD/Solaris/MacOS X/Linux shop; and found it was
worth putting in virus checking just so we wouldn't have to wade through
the piles of sobig.f crap in our mailboxes.

This list really can't be considered to be anywhere near complete without
including Exim. Particularly the latest versions with the exiscan-acl
patches. Those not only allow you to integrate virus scanning and anti-
spam features into a powerful, flexible ACL; those ACLs let you reject
the offending message while the SMTP connection is still open. (So no
undeliverable bounce messages clogging up your outgoing queues.)
(The FreeBSD mail/exim port automatically includes the exiscan-acl
Exim is easy to configure, -very- flexible, and capable of handling
fairly large traffic levels if required.
I can also heartily recommend clamav as a virus scanner. (Also
installable via a port. As is SpamAssassin.)
