You might want to consider a two-staged mail system
where the front/visible ones run your spam filtering
and virus scanning and then forward to your
backend systems that deliver to users mailboxes.
Real virus scanning can be quite a resource intensive
process as it has to crack open attachments, untar and
unzip files searching for nested archives and so on.
Consequently you may find that the system requirements
for a front-end/virus/spam scanner are significantly
different from a backend, mail delivery system.
