Create the mx record both domain in internal dns server.


Make sure configured Anonymous Access on the SMTP Receive Connector to receive mail from remote servers that have these IP addresses.

If both server are same active directory domain then you don't have work on the issue.

Default, no explicit Send connectors are created when the Hub Transport server role or the Edge Transport server role is installed. However, implicit and invisible Send connectors that are automatically computed based on the Active Directory site topology are used to route messages internally between Hub Transport servers.
