Impossible. They don't have any "GOOD SECURE mail server" at "A Micro$oft Shop".

Actually Michael, Exchange is probably one of the more secure Microsoft
products. It certainly appears to suffer from the fewest bugs. However, many of the Exchange servers I have seen have been sitting
behind Qmail, Sendmail or Postfix running on OpenBSD or some Linux
variant.  A smart move, probably.  It is my humble opinion that Exchange
is rather bloated and suffers from feature creep like much else out
there.
It also has problems dealing with more than a few simultaneous port 25 connections: it didn't used to be able to handle more than one, but my reports from a user in the field says that it still bogs down badly with more than a dozen simultaneous incoming messages. This is one of the reasons for the very low maximum size for incoming messages on such servers, to help keep the connections short.
