I do a lot of testing for customer installs. I have an sbs 2003, exchange 2003 domain setup for our office email. I also use VMware running sbs 2003 and exchange 2003 in a test environment. I would like to be able to test incomming e-mail on the test domain, without reconfiguring the router/firewall box (i.e. port 25 and https for OWA). How can I route testdomain.com thru mydomain.com? Remember 2 separate servers running thier own exchange domains. 1 IP address Would prefer not to reconfig the router/firewall to point to testdomain. (because then we don't get our regular e-mail!)

Setup a second MX record for testdomain, and have it point to your current IP address.

That won’t help. The router routes port 25 to the Internal IP address for mydomain.com. I can’t route port 25 to two different internal IP’s.

In Exchange System Manager, create a second SMTP Virtual Server and set that to port 2525. Then port forward that port.

That sounds like a logical solution. However, right now I port forward port 25 to mydomain internal server IP address, I can’t port forward to 2 different IP addresses.

Port 2525 or your choice on your second server. Leave port 25 for your original server.

AsI thought, Making a new virtual smtp server on port 2525 and forwarding my router port 2525 to testdomain did not work. By default all smtp incoming traffic uses port 25!

    Your client needs to know what port to use, it won't find out on its own. Change the SMTP server port to 2525 on your client.
