Unhappy telnet localhost 25 not responding

Hello Falco and once again thank you for your great work on your Howto's.

I am a happy owner (or at least was till today) of a mail server setup as instructed in your "Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 6.10 Edgy Eft)" tutorial.

I cannot connect to the mail server's smtp at all. Trying to troubleshoot it myself I tryied conecting locally through ssh and telneting port 25

The server replies:

Quote:
root@mail:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
but
no mater what I type next there is no response

If I telnet port 110, I get:

Quote:
root@mail:~# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
+OK Hello there.
quit
+OK Better luck next time.
Connection closed by foreign host.
root@mail:~#
as normally expected.

Same happens for both port 110 and 25 if I telnet from outside (internet). Pop replies and works fine, smtp replies but doesn't respond to any input.

What could be going wrong? Can you please guide me to troubleshoot this one?

Thank you in advance for your time.
