Internally (from the server itself) if I telnet to port 25 I get the normal response giving me the name of the server etc.
Externally I get what looks like a success full connection, except, it is blank, and as soon as I hit any key I am disconnected.
I have the same rules on the DLink Router/Modem to allow port 80 in from anywhere and port 3389 from anywhere
I can establish a remote desktop connection to the server without any problem.
But cannot bring up the Exchange OWA or a SMTP session.
this is regardless of weather I use DNS resolution or IP address, so DNS resolutuion is not part of the problem.
Any Ideas boys and girls?
