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.
