Clean Accepted Domain out of Exchange 2010 infrastructure

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.
