DNS won't register MX record

By chipw ·
I am trying to add a MX record into our DNS server, NT4sp6a, but keep getting an error - Unable to register, please correct the settings. Seems no matter what I enter I always get the same error. All I need is to allow an Exchange server to send messages out of our network to the internet. These messages are auto-responses, no users messages.

The Exchange server does not need a MX-record to send mail out of your network. The MX-record is used when other mailsystems look up your domain to send mesages to you.

To send mail out of Exchange your server must contact a DNS-server to find the MX record of those you want to send mail to. These MX-records are found on the receivers DNS-server not your own.

If you have trouble sending mail out to the internet you should check the DNS setup of the server running Internet Mail Service.

I'm not sure DNS is the problem. I can send mail out just fine from my FreeBSD box. The Exchange box has the same DNS servers listed but the messages just hang in its queue. The FreeBSD box has some relay domains listed - just a couple computers inside my network allowed to send mail through it. The Exchange box has the same relay domains listed in its setup.
