Exchange 2010 Outbound Mail keeps going via Exchange 2003
I am migrating from Exchange 2003 and Exchange 2010. All mailboxes have been moved out and can send/receive emails.
For some reason, I cannot set the Exchange 2010 to send mail outbound by itself.
As soon as I delete the routing group between 2003 to 2010, mail does not flow outbound (Inbound to 2010 is fine). When I add the routing group back, mail goes out. This suggests that mail is still going out via the 2003 Mail Server.
I have correctly created a Hub Transport Send Connector with * Address space and cost 1, setting as Internet and using our normal smarthost, but still no luck.
Somewhere I am missing the obvious but cannot work it out, please help?
Quick Background on this.
Exchange 2010 setup with all roles one one server. CAS setup correctly pointing to a CASARRAY DNS address.
DAG setup with DR Exchange 2010
All up to date ServicePacks applied
Thanks

Hi,
Previous Exchange was setup by another guy and when I checked the firewall, outbound is fully open.
Inbound I have used another public IP for 2010, but inbound email to Exchange 2010 is fine.
The mail is routed via a smarthost from Messagelabs

check if the source server is your hub transport server in send connector.

Yep, send connector is created, however I think I might now where the issues lies. I have not added the public facing IP address of the Exchange 2010 Server into the Messaglabs console which is out smarthost provider. Takes 1 hour to update, so will know if that is correct or not
thanks
thanks
Did you opened the port 25 for Exchange 2010 on firewall.
You can enable SMTP log to further trouble shoot the issue.

IP address is already in Smarthost website.
Outbound on the firewall in all open., but good idea on checking the logs

you can alos try to remove the routing group connector and send connector and recreate the send connector.

just tried that deleted RGC and Send Connector, created new send, still now luck

ok, guys, I must have had a Brain drain. The issue was the other way around. I could receive email to 2010, but not send from 2010 unless RSG was connected.
The fix was to go into my Smarthost portal and change the inbound route to point to the public IP of the Exchange 2010 Server, was set to 2003.. DOH ! will take approx 2hrs to update
