Exchange 2003, 2010, breaking the connector

my exchange 2010 server is up and running along side my exchange 2003.  I've moved the OAB, Public Folders, etc and I'm ready to edit my firewall.  When I point all my port 25 traffic to my new IP, i get an error (#530 5.7.1 Client was not authenticated ##).  I'm thinking its becasue I still have my 2003 server up and the connector is routing all traffic thru that old server.

thoughts?  will simply breaking the connector work?  Or must I do more?

Thanks

Cliff

how have you planned the co-existence ?

For a 2003/2010 co-existence, let Exchange 2010 receive emails (port forward to exchange 2010) lan IP - and then route emails from 2010 to exchange 2003

you need to update your "Default Server" receive connector adding the anonymous permission group

the exchange 2003 existed previously.  I added the 2010 server with the intention of taking down the 2003.  I'm at the point where i think I'm ready to take the 2003 out of the loop and send all mail to the new server.  So, I edited my router and sent all 25 traffic to the new server and I got the error.  I was thinking of now deleting the connector from the 2010 to the 2003 server.

Disable the firewall rule which points to 2003.
Create a new rule pointing to 2010 and check.
