We use a combination of Amavisd, Clamd and PostFix on our mail servers at our colo facility to scan for virus first, then spam before the mail is routed to our Exchange server internally. We use Centos as our flavor of *nix on these servers. As with most *nix solutions, free except for the time to learn/configure, but it does work very well.
When we implemented this a couple of years ago, we actually got phone calls and emails from users thanking us for whatever it was that we did because they weren't getting spam anymore.
