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. Subject: test Sent: 3/4/2002 12:16 PM 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.
