Have exchanged installed but SMTP port is closed?

Last Modified: 2013-11-30
Ive configured my new exchange box, it all looks good. However, sending test emails have failed and tests show that telnet to port 25 on the server IP is refused. Internally I telnet to the box and am refused. I dont get it.

I have enabled EHLO access to the FQDN. I have disabled firewall (for testing), what else is there? I would have thought that exchange install would have opened the port. Its not the firewall, ive checked and besides ive mentioned I did an internal telnet test and failed.

What am I missing?
