I have an Exchange 5.5 sp4 installation on NT4.0 sp6. When trying to send
email to the qnx.com domain I consistently get the following error:

Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

      '[EMAIL PROTECTED]' on 3/4/2002 12:16 PM
            Unable to deliver the message due to a communications failure
        The MTS-ID of the original message is: c=US;a=
;p=TransCore;l=SD-MAIL1-020304201531Z-12641

Simarly configured exchange servers at other sites within our Corporate
setup are able to send to qnx.com and qnx.com can send to me without
problem. I get the same error whether I send it directly to the address or
reply to one they've sent me. I've checked the dns used by my exchange
server and it's able to resolve the mx record for qnx.com. I'm out of ideas.
Any help would be greatly appreciated.
