RE: [cobalt-users] Closing port 23



Okay, then is there some way of not allowing telnet connections to
port 25 yet still have a mail server capable of sending mail out
to the world?

Tom Nelson


port 25 is your mail server --therefore, you can telnet to x.x.x.x 25
you have to turn off mail server to prevent telneting to port 25.
