How to configure send connector in Exchange 2007 to route back through Exchange 2003?

Our Exchange environment consists of Exchange 2003 and Exchange 2007; we are in the transition phase.  Users with mailboxes on Exchange 2003 can send and receive internal and external email, including mail from users with mailboxes on Exchange 2007.  Users on 2007 can send to and receive from users on 2003.  The users on Exchange 2007 can also receive external mail but they cannot send external mail.  Messages that are sitting in the queue have an error of:  A matching connector cannot be found to route the external recipient.

Currently there are no send connectors set on the Exchange 2007 server and Im hoping that someone could explain how to configure the Send Connector to route external mail so that it goes through the Exchange 2003 server?  Perhaps this isnt necessary?

Im fairly new to Exchange so any assistance would be much appreciated.

Hi,
You do not need a Send Connector on Exchange 2007 till the time you SMTP Connector on Exchange 2003 that is taking care of External Mail.
Make sure that all Mails being routed from Exchange 2007 goto Routing Group Connector that has been created between 2007 and 2003.

So, I dont need to explicitly set up a send connector on my Exchange 2007 until I decommission the Exchange 2003; correct?  

How would I verify that mail is being routed via the RoutingGroupConnector?
See if you want to send mails via Exchange 2007, then it can be configured and mails pushed to Smart Host.
It is your call, I am not aware of your setup, hence my suggestion is that if you are contonuing with Exchange 2003 for external mails, then on Exchange 2007 you do not need the Send Connectors.
Routing Group Connector would take care of pushing all mails (External/Internal to 2003 users).
Hope this helps
Thanks
