It's been *many* moons since anything except ratware failed to do MX handling in some reasonable manner. I mean, come *ON*, MX records were defined in RFC973.

You will experience a few external sites that will have trouble sending to you. These will all be badly configured MS Exchange servers that can't cope with MX records. They'll want to be able to connect to the destination IP SMTP port directly. When you speak with their mail admin, you'll find they have no concept of what an MX record is. RTFM is the correct advice to them.
I stand by my categorization of "nothing except ratware". If MS Exchange *ever* shipped with MX turned off by default, *or* if it made it trivial for an unclued admin to disable it, it's broken ratware even if it *is* in widespread use. It's really gotten to the point where we need to say "Your clue must be this tall to ride the Internet". I'd almost recommend *against* suggesting that they RTFM to figure out how to fix *this* problem, because once they do, they will be sending you all *sorts* of broken and misconfigured stuff. All that getting their system working will buy you is a a continuing maintenance headache. ********** Participation and subscription information for this EDUCAUSE Discussion Group discussion list can be found at http://www.educause.edu/groups/.
