Re: Telnet port 25

smtp runs on port 25. You do not need sendmail running to send mail out of
a box. Once you stop sendmail, telnet to port 25 will be closed.

Can someone point me in the write direction as to how I would easily
disallow telnet to port 25, but still allow telnet to port 23?

I.e. I don't want to be able to telnet to port 25 and send mail, but I
still want to run sendmail, and allow telnet… or am I looking at this
wrong? Thanks.
