If you're running anything beyond a trivial private/boutique server,
this will end up causing problems for your users sooner or later.
Even as the admin of many hats for a small ISP a while back (~1500
dialup users plus a handful of dedicated wireless links and ~50 hosted
domains) I wouldn't have implemented a policy like that; too many
customers received perfectly legitimate (if tainted-by-Exchange) mail.
Or used our mail system as a smarthost.
I wouldn't even do this on my *own* personal machine; all three main
accounts periodically receive mail that's passed through an Exchange
All that said.... Your system, your policy.
