Dear List,
I have just finished setting up a mailserver... or so I thought.
However I could not telnet to port 25 either locally or on any machine

================================
I could not pin down why this is happening. I already googled for
similar problems but most of the results that I saw can still connect
to the localhost... I can't...
Is there any setting that I missed?
Any similar problem you encountered? How did you get around that?
Sincerely,
*almost* hairless mhac
(i can't help but pull one off for every solution i tried that failed.. )
