RE: Stumped Mx record
If your email is reporting undeliverable for www.pantex.com then that is probably exactly what it should be doing. Now if it was reporting undeliverable for pantex.com that would be different situation.

RE: Stumped Mx record
Get your network people to work with you to draw a chart that step by step, maps out exactly how name resolution works in your environment. Once you have the map, then the answer to your question will be obvious. Without the map, all we can do is say well, if your map looks like this, then your problem is that. I don't think that will help you. -Original Message- From: Stevens, Dave [mailto:[EMAIL PROTECTED]] Sent: Monday, February 04, 2002 10:37 AM To: Exchange Discussions Subject: Stumped Mx record have any of you seen this before My mail system has host unreachable for this domain: www.pantex.com.

That should explain why our mail destined for them sits in the queue. RFC-974, page 4, says that if no MX record is present for a domain, the SMTP implementation should treat the domain name as a mail host, and attempt to connect directly to it. As the host at the IP address listed for pantex.com appears to be a valid mail exchanger, I would say they are using that case. -- Ben Scott [EMAIL PROTECTED] | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
