The error when trying to telnet to IP is: Could not open connection to the
host, on port 25: Connection failed

I ran netstat -an and port 25 is open for the localhost but not for the
192.168.0.1. Thats interesting why would the localhost be open but not the
actual IP.

I am not running any personal firewall on the server but I do have a netopia
firewall for external access.
