Exchange 2007 - can't email 1 domain (army.mil)

I'm trying to figure out why I can't email a few folks at various army.mil addresses.   some are at usarec.army.mil and some are at us.army.mil, etc.    I can email marines, navy, army corps of engineers and even secretary of defense addresses.  But for some reason, I can't send anything to the army.

gmail works fine, just from my exchange 2007 server, I have issues.  And only with the army.mil server.

I checked mxtoolbox.com and my server isn't listed.

I get a delay after 4 hours, then a failure the next day.  

I'm thinking it's a dns issue?

It coud be DNS problem. But gmail dont using lots of security technologies. Are you using SPF or another feature? Have you set dns record to your comapny? Do you using static IP?

As mentioned post the failuremessage here and also send the mail to army from other user in ur domain and see he is also getting the same result or not.
If he didnt get then the issue is with ur mailbox and if he gets the same error the issue will be DNS or some thing else..

I've tried changing the address space in the send connectors.. no luck there.  What's strange is that this is the only domain that I can't send to...

Hi James,

Are you able to provide full headers from one of the mails sent through the same flow that are being delivered successfully?  Sanitized as needed of course, but try to not mangle it too much.  Basically I'm looking for envelope and body from, return-path, sending server IP, any auth results as reported by the receiving server, and anything else that seems abnormal.  How your mail is treated is completely dependent upon the receiving servers' policies, which is why you are seeing inconsistent results while sending to/from other addresses/domains.

I don't know the public IP and/or hostname of your sending server(s) so I can't check DNS for that.  I can assume it's mail.wcsecurity.com but that is just a guess.  There is no SPF record for wcsecurity.com which could also be a contributing factor.

I got it figured out.  I have a dns service that the Army considered a ghost service, and therefore they were rejecting it, thinking my domain didn't exist.  Basically I have an account at dns2go  so that if I have to spin a server real quick I don't have to wait for propagation.  All I'm using dns2go to do is point to the actual router/machine and all of my domains are with their servers for dns.  So propogation is always in place already and I just change the pointer in a few seconds if needed.... well, the army didn't like that.  I moved that domain to network solutions for dns and it's all good now.

My hunch that it was a dns issue was correct.  After a few hours of testing and moving the dns server to another service, all is good.
