I suggest you look at MailScanner + SpamAssassin + the virus scanner(s) of
your choice.  MailScanner integrates with sendmail/postfix/exim and will
automagically call SpamAssassin and the installed virus scanners. 
MailScanner supports most major scanners.

I personnally use ClamAV (a super open source app) along with F-Prot and
MicroTrend.  MailScanner includes scripts to check the virus scanner
websites for updates on regular intervals.  It's interesting to see which
one is updated first when there's a virus outbreak.

If you really want to be thorough you can also install pyzor and razor. 
SpamAssassin will use those if they're installed.

This setup is surprising easy to install.
