Is that possible at all? I mean, a mail server should be able to receive
mail for local users in any case. Imaging an external mail server, say
from hotmail.com. If another user (assume no spammer...) wants to send
you a mail, it will be resent (relayed) by hotmail which in turn will
send it to the MX of your domain. But hotmail won't have AUTH data for
your mail server, so this must work unauthenticated. You get the point?
So if you require authentication for *any* user, you won't be able to
receive mail from the outer world any more.
