550 5.7.1 Unable to Relay for (username@domain.com) (IP Address) doesnt like recipient.
Ok guys we have a Hosted Exchange server with about 15 domains on it. Every single user in every single domain is working perfect except for one. In the domain in which he resides every other user is also working correctly. He is not a new user and he has been receiveing mail just fine up until a couple of days ago.
He can send mail anywhere(outside and inside) and he can receive mail from the inside of his domain and any other domain in the hosted exchange. When anyone from outside tries to email him they get the error message
Remote host said :550 5.7.1 Unable to Relay for (username@domain.com)
I have recreated the recipient policy, restarted services etc etc. and i just cant figure out what is going on with his account. I have even recreated his account and tested it to no avail. Anyone have any suggestions would be greatly appreciated.

Check in his AD User properties to be sure his Exchange General/Delivery Restrictions has not been set to accept mail from authenticated users only.

Is there any automatic forward setup on the account in active directory? It could be failing at this point. Check for a forward, then check for 'allow mail from authenticated users only' on that account it's forwarding to also.

Hypercat i found the problem. One of my coworkers mispelled the name of the domain in the local domains area of our spam server which runs GFI. haha
LOL - those little typos can really cause large GRIEF!! Glad you found it. Cheers.
