A popular open source solution is Linux or BSD boxes running
SpamAssassin, Amavisd and ClamAV.  They are quite effective at
stopping spam and viruses, but require some initial configuration
and later maintenance.  The wikis can be useful:

If you're looking for a hardware solution, I have no answer....
