I have a user reporting NDRs to a particular domain.

Delivery has failed to these recipients or distribution lists:
Microsoft Exchange has been trying to deliver this message without success and has stopped trying. Please try sending this message again, or provide the following diagnostic text to your system administrator.

Microsoft Exchange has been trying to deliver this message without success and has stopped trying - Its recipient domain issue so let them know and have a check.

The domain in your NDR is alive, you can check that for yourself with mxtoolbox or similar. Therefore it is a connection issue or a routing issue. Do check with the recipeint that they aren't filtering your email.

To me this is either your server was not able to deliver email cause of network issues OR the recipient domain server had issues accepting (as said by above two EE champs). I don't see an issue with the recipient domain as listed in screenshot below - so check if you can telnet from you're box to their MX Record mail.fcmc.com and drop an email and ask them to verify.

So it turns out that still failing to deliver to fcms.com and mit.edu.  On the queue viewer in the MMC i have No Recipient succeeded and message delayed.

Delivery is delayed to these recipients or distribution lists:
Subject: sipb-jobs and jobslist drafts (fwd)
This message has not yet been delivered. Microsoft Exchange will continue to try delivering the message on your behalf.
Delivery of this message will be attempted until 9/22/2012 11:46:51 AM (GMT-08:00) Pacific Time (US & Canada). Microsoft Exchange will notify you if the message can't be delivered by that time.

If it telenet to my exchange server and try from there i get a:
"unable to realy" message

I checked and i am not black listed..

If you are get an error when you telnet to the server, then the problem is with the remote side. Just because you are not blacklisted on any public blacklists then it doesn't mean you aren't on a private blacklist. Many of the major service providers use their own blacklists, even I have a private blacklist. You need to contact the recipient and get them to check why they are rejecting email from you.

I fix my issue by adding an external PTR record.
