Microsoft, Exchange, 2003, can't relay mail to different servers on the same LAN

I am asking this question again -

1 have 2 Exchange servers in a colo facility.  Each one is a standalone AD domain controller I am unable to send email from exchange.domain1.com to ecxhange.domain2.com - I have tried using external public DNS for this and it didn't work. So I created DNS zones on each server for the other domain and added MX records  -  both with internal IP addresses on the same LAN - No dice -  Attached is a picture of the scenario.   I don't get why the server at domain1.com can't just send out to the internet to the server at domain2.com  via public DNS address but I suspect it has to do with the handshake and the fact that the servers are both behind the Cisco firewall - Maybe there is a way to do this by creating connectors.  If someone could help me with this I'd really appreciate it.

Cisco pix is configuret to do PAT to either server - mail flows to and from each domain from any other mail domain.

Do you get an error message?

What do you have for exchange connectors?

Just the default SMTP connector on each server which accepts email from the outside - I am not sure how to create connectors to communicate between the two servers.
