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 machine. All that said.... Your system, your policy. -kgd _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
