Exchange 2003 does not necessarily have to
use the IMC as this is for backward compatibility for Exchange 5.x and Exchange
2000 servers.
Check your Routing Groups and make sure
that there is an SMTP connector configured and that both servers are listed
there.
This should work if both servers are part
of the same administrative group.
If each server is in its own
administrative group then a separate connector must be installed for each
server with its own remote bridgehead connector to the other server so that
each can route mail to each other if needed.

Subject: [MSUNAG] Adding Exchange
Server to an Exchange organization
We recently added a new Exchange Server (2003) to our
Exchange 2003 organization. Our Internet Mail Connector is still on our
original mail server and we added the new server as a bridgehead server to this
Internet Mail Connector. The users that have mailboxes hosted on the new
Exchange server can send e-mail outbound to the internet without trouble with
the exception of two domains so far. They are aol.com and
Comcast.net.
It appears from headers that I have looked at that the
accounts being hosted on the new e-mail server are going directly out to the
internet from the new box with SMTP and not going through the Internet Mail
Connector on our original mail server. I had thought that all internet
bound (outbound) e-mail would route through the IMC on the original mail
server, but I was incorrect.
For those mailboxes that are still on the original Exchange
server, e-mailing aol.com and Comcast.net isn’t an issue.
Any thoughts or advice?
Thanks,
