You have plenty of people trying to help.  However, one thing they've missed is informing you of what the symptom means.

When you do "telnet host 25" there are (generally) 3 possibilities....

telnet: connect to something: Connection refused    This means no process is listening on the specified port.

telnet: Unable to connect to remote host: No route to host    This means the port is not open (a.k.a closed or filtered) on the firewall.

And of course the 3rd possibility....

Connected to something.com.
