I have exchange 2010. The issue i am having is i cannot recieve email from one paticular domain. I have tried turning off all spam features on my edge server, i have run several of the reports in tools and all seem to come up fine. Except for one error
I recieve Error submitting mail Mail submission failed: Error message; The SMTP host was not specified. I do not believe this because we are recieving emails from other domains just fine. Was able to recieve email fine from this domain up until yesterday.
I have also rebooted the machine to reset all services. I have tried to track the email and it goes out of the sending exchange server just fine. However i cannot even see where it hits my edge server. Any ideas would be greatly appreciated.
