I recently had a problem similar to your problem. I could NOT email to a certain user. After some troubleshooting I discovered that the problem was NOT at my location but at certain user's location. That certain user troubleshot the problem at his location and discovered and solved the problem. That certain user never told me what the problem was and how he solved the problem.

It doesn't matter who sends the email we always get the samething "The destination server for this recipient could not be found in Domain Name Service (DNS). Please verify the email address and retry. If that fails, contact your administrator." We are able to send to other people in that domain. We have verified the the email is correct except in the queues it shows the domain it is being sent to as incorrect. Is there anywhere to delete the relationship for that user?
