Not if they run MS Exchange. I've testing online with a user while I had him on
the phone.. all MS says is something bland like, "Can't deliver mail"... even
though my server sends back a very descript failure code and message.

So the users (trained in the ways of InternetExploder) just figure there's a
"DNS or server error" and sit at their desks and cry. (I'm guessing to some of
that of course... but not the crying part.) ;)
