xexch50

The problem is that they also have an exchange server trying to communicate
with you.  When that happens, it's told to try and authenticate and because
it's not a member will likely fail.  If this is an internet facing mail
handler, you should not expect other hosts to have to authenticate in order to
send mail to you. That would be a configuration error on your part and a silly
extra verb on the part of Exchange. ;)
