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?
