well, pop/imap shouldn't need any virus scanning, that would be handled
at the SMTP transfer layer, by something like MailScanner + ClamAV (I've
used this combination), or spamassassin+clamav, and others.
http virus scanning can be done by using Squid as a transparent web
proxy agent and squid plugins. I've never attempted this myself, so I
can't give you the exact recipe.
