This doesn't make much sense to me.... Is it not possible
to set my smtp service up so that it requires
authentication, and yet still be able to receive emails
from the outside world? If it's not possible that really
makes for a hard decision. Do I want to leave my email
server open for anonymous relay and have spammers use my
server freely, or do I want to enforce authentication and
not be able to receive any email from the outside world
because the other email servers don't have authorization?
I tried adding IP ranges to the Relay Restrictions list,
but that didn't do any good. It's as if the SMTP service
is ignoring that list when it decides whether or not to
accept an email. What am I missing here?
