I have some accepted domains in my Exchange 2010 server that I am not wanting to receive email for, nor have them part of the system. I removed them from the Accepted Domain list, but now that the domain is hosted elsewhere, I cannot email that domain from my system. It's like they are still in there somewhere. My Exchange server thinks they are local, but they aren't anymore. Any email sent to a user with that domain name comes right back undeliverable, even if nobody in AD has an alias to that domain.
I have read other posts but can't seem to resolve. Some talk about getting the IIS7 Metabase explorer and cleaning them out some other way? Can anybody help me, I am lost on this one.
