When I was running the network at NCC oh so many years ago, I 
solved this by putting what you might call a "mail proxy" server 
(at that time, Qmail on an OpenBSD box) in front of the Exchange 
server.  Exchange sat safely inside the firewall, and only saw 
the stuff that made it through our Qmail filters.

No users needed on the Qmail server; it just filtered stuff and 
passed it on in.  Saved our butts numerous times.
