I installed that combo at 10+ customers, with varying sizes (2 person desk
to 20000 user ISP [load balanced there]).

All I can say: it's a real charm to configure and run, and in combination
with ClamAV (http://clamav.elektrapro.com/), a free virus scanner, the best
open source combo after LAMP. Even if you (or your boss) think you don't
_need_ virus scanning in front of your exchange server (duh), I found it
wise to have two or three different scan engines running in parallel...
(Once upon a time a client's machine didn't update their patterns for some
kind of reason, and got hit by BugBear).
