Best Antivirus Options for a Mailserver?

CSIP asks: "I am setting up a small mailserver, with ~500 users, across 80 domains. I'm planning to use qmail-scanner and an antivirus scanner to block incoming viruses. I would prefer to use ClamAV, however I've read conflicting reports on its effectiveness. The commercial scanners appear to detect 99.X% however they are licensed per-user, which at 500+ users becomes quite the annual bill. What is everyone's experience with ClamAV? Are their other commercial scanners that allow you to license on a per-server basis?" The best indicator of quality for a virus scanner is the information in its virus database. How do ClamAV's virus definitions compare to commercial scanners, like McAfee's?

    Really, I don't understand the point. You have your users jumping through hoops, but you've done nothing to actually rid yourself of viruses. The only thing you've 'educated' your users about is to follow silly BOFH instructions. All this when there's a gazillion easy to implement solutions which are both convenient and work.

    This is the biggest problem with computer nerds. It's not just that they occasionally have a ridiculous idea -- it's that they will stubbornly defend that idea to the death, generally falling back on the olde "Users Are Stupid" saw. This tendency single-handedly explains most of the mal-designed systems out there.
