I have recently installed an Exchange 2007 server in my organization. The server is located behind a firewall, and withing the firewall I port the public IP over to the private IP address. I would like to keep this setup if possible.
Though, whenever mail is sent out, the message headers state the internal machine name and private IP address of the server. I need to change this so it sends mail out as the public IP and puclic machine name I used for my MX record, but I don't see where I can do this at.
When I telnet to the server, the helo information has my public name.
How do I set this up?
The information is similar to:
Internal IP of Mail Server: 192.168.1.1
Internal Machine Name: myserver.corp.mydomain.com
Public IP: 220.127.116.11
Public name/MX: mail.mydomain.com
Thanks for your help.
