mail between 2 servers in same organization not delivered

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?

First - you don't need to add the IP addresses to the hosting table, so take them out.
Next - there will not be a setting that you haven't made, more like a setting you made on the old server.
The most common reason for message delivery failure is a smart host on the SMTP VS.
ESM, Servers, <your server>, Protocols, SMTP. Right click on the Default SMTP VS and choose Properties. Click on the tab delivery and then advanced. Ensure that smart host is clear.

If you need to use a smart host, then configure an SMTP Connector (http://www.amset.info/exchange/smtp-connector.asp).

If that is blank, then check connectivity. Telnet to port 25 of the other server...

telnet ip.add.re.ss 25
telnet servername 25
telnet servername.domain.com 25

If that works - then you have connectivity. If it doesn't, then you need to investigate the blockage.
