Okay I hope I can describe this properly. We used to allow emails addressed to a secondary domain (formerhosteddomain.com) to be delivered here (Primarydomain.com). We have since transferred ownership, and also removed the MX record from register.com that used to point to our email server. So, anyone from the outside world can email to firstname.lastname@example.org however, no one from @primarydomain.com can send an email to that address. The error message is pasted below. I have removed the formerhosteddomain.com from the recipient policy from Exchange System Manager and restarted IIS, but no dice. Any ideas??
184.108.40.206 does not like recipient.
