Do you have a domain? Does the MX point at the hostname of your server?
(which should then have an A record with the IP of your server) Does the
username of the email address exist on your server?

What is the email address you were trying to send to?

What was the entire bounce message?

Yes I have, and then I asked my provider to change the MX record.
Now the original domain is www.gseserver.net while the MX record is
mail.gseserver.net. Both domains point to the same IP address (the IP of my
ADSL connection).

Yes. In my home I've 4 PC in the same LAN. One of them is the server
(directly connected to the Internet), and there is a "paolo" user who can
send mails in the Internet and receive mail from the other 3 LAN PC but not
from the Internet. I think only local mail is received, but I can't
understand why.

Thanks a lot!

Er, you mean, the domain is 'gseserver.net', and the MX record for that
domain points at the _host_ 'mail.gseserver.net', for which the IP
address is 213.155.200.101

I assume someone on the Internet is trying to send to
'paolo@gseserver.net' ?

I dunno about anything else, but your server is accepting SMTP
connections and immediately closing them (see below.) You'll need to
figure that out and fix it before you can go any further.

It would also help if you posted the FULL bounce message that the
outside user received when trying to send..

$ telnet mail.gseserver.net 25
Trying 213.155.200.101...
Connected to mail.gseserver.net.
Escape character is '^]'.
Connection closed by foreign host.

Are you trying to send to 'paolo@gseserver.net' ??

Post the _FULL_ bounce message that the outside user received.

Oops.. ok! Excuse me but... I'm a molecular biologist! Informatics is a
recent passion, and for me it's difficult to correctly translate the tech
English of the documentation. So, "www" and "mail" are hosts. I called them
"third level domain".

Right!

I use KMail (in a Madrake8.1/KDE3 system), which returns a window saying:

******************
Sending failed:
The server didn't accept one of the recipients.
It said: 5.1.1 <paolo@gseserver.net> is not a valid mailbox
********************************************

That's interesting. I have no idea for that. Do you use a Linux system (well,
with pine..)? May you try to suppose what can be the problem? Why it should
accept the connection and then close it immediately???

Thanks again! :)

Try telnetting into port 25 on your server, and issue something like:

EHLO gseserver.net
mail from:<paolo@gseserver.net>
rcpt to:<paolo@gseserver.net>
data
"anything you want"
.

And post the output>

Have you tcp-wrapped the smtp daemon?

Should show up in /var/log/exim/main.log.
