hi,

i need to setup an smtp virtual server for my exchange 2003 machine so a database in another network is able to connect and send mails from our domain

i have setup the smtp virtual server and checked the relay options, but when i try to connect to the WAN IP port 25 from another network and am getting connection refused, port 25 is definitely open as exchange is working

Is the machine in the other network coming in through the firewall via the same route (ie externally) or is it coming in from another internally facing interface.

It sounds like you might need to add another rule on your firewall to specifically allow this new traffic to pass on the required route through.

Have you checked the firewall logs?

It's difficult to say without knowing your specific configuration. Is the server connecting to your Exchange on the Internet, or on another internal network?

If it is an internal network on another firewall interface chances are you are not using NAT between those anyway so you shouldn't need any sort of port forward rule, just an allow rule, and then you'll likely just need to connect directly the internal IP of the Exchange server, assuming there is a valid route and allow rule as above.

I wouldn't have thought you should be connecting to the WAN IP to come in unless you are actually in fact coming in from the Internet. If that is the case why wouldn't you just add the other networks/servers public IP to the relay permissions of the default virtual SMTP server.

If the application can authenticate with Exchange then it will be allowed to relay by default. So it is quicker, to configure a user account and password for it to use if the application can do authentication.
