block emails from one internal domain to other internal Domain RRS feed

  • Question

  • We are using exchange 2013 and configured multiple authoritative accepted domain and created UPN in AD for these domains. I want to block emails from one internal domain(UPN suffix) to other internal Domain with different UPN suffix and want to assign different GAL on internal domains. How i can achieve this functionality.

    We are using internal transport agents for filtering of emails.

  • The only way that I can think of would be to create a transport rule that matched the domain in the recipient's address, and somehow matched the sender (maybe to a dynamic distribution group), and then block the email as the action.
