As others have pointed out the virus scanning is best handled by the MTA
not your imap server. This allows outgoing mail to be scanned as well which
is good when a virus such as sircam gets through (say via a web browser
email site) and starts spreading elsewhere.
For us the primary condition of a suitable product was that it must have
strongly configurable anti-relaying features. Some products run as their own
daemon but have very basic config options. I rejected all of those products
last year when I was evaluating options.
I think the best ones are the ones that seamlessly integrate into your current
MTA. We are a sendmail shop here and are using inflex which is similar to
Amavis. Inflex is just a hook between sendmail and our virus scanner which
happens to be Sophos.
I'm very happy with Sophos on Unix. I had to write a few scripts to
automatically update the virus defs, but that has proved to be much simpler
that doing similar things for our Windows machines...
