mail between 2 servers in same organization not delivered
Posted on 2006-05-25
I've recently setup a 2nd Exchange 2003 server in my organization which seems to be functioning well except that I can not send messages back and forth from users on the 2nd server to the original one. Both are Exchange 2003 Enterprise SP1, all updates installed.
I can send out and receive fine externally. I can send and receive from users that are on the same server. I can receive messages sent from a user on the original server to one on the new server. I just can't send or recieve to anyone on the original server from the new one.
I've added the ip for both servers into the allowed relaying hosts table. I waited a night for the offline address book and public folders to replicate, and they seem to have done so fine. When I send a message to a user on the original server, it sits stuck in queue.
I assume I have to be missing a setting somewhere, but from what I can tell I've matched the settings between servers to be identical. What else could I be missing?
