Here at UW River Falls I've just recently implemented site-wide mail scanning. We're using a front end system with Mimedefang running as a milter. It's calling McAfee viruscan - which I'm not crazy about since it needs to fork viruscan on every email. But we have a site license :-) I think using sophos and the sophie daemon would probably work much better. But this is actually working pretty well for us so far - though the students are starting to come back today so ask me again at the end of next week :-(. We have about 6000 email users and are currently shipping an averag of 25 mails per minute, with peaks more like 100. We're running a 2-cpu SMTP front-end server that most of the time is loafing along with a load under .3 I don't know if that helps any?
