I am trying to understand why a SMTP service on my box for port 940 can be accessed via localhost by not my box's IP. I've checked my firewall, etc.
Please understand my question is regarding network configuration, not email services.
My question is, what could be blocking this access ?
[$ telnet localhost 940
Connected to localhost.
Escape character is '^]'.
