I run my own mail server on an persistent adsl connected computer.
The name of this server is gateway.mydomain.net running postfix 2.1.5 on a
debian sarge OS, personalised kernel 2.4.33.
I check my mail logs and I don't uderstand few lines and would need avanced
users advices.
Of course I don't intend to relay mail from my server
I thing to have succeeded but I'm not very sure ...
In my postfix/main.cf I put lines :
mydestination = $myhostname, localhost.$mydomain, $mydomain
mynetworks = 127.0.0.0/8, 192.168.0.2, 192.168.0.248/29
In logs I can regularly see this kind of suspected lines :

======================================
I'm not an expert but I don't understand why this mail to <cpabx...@hinet.net>
is sent.
Did i miss something in the comprehension of logs or my computer is used as
a relay ?
If some of you could light my mind.
Thanks to everybody for answers and sorry for my poor english.

I checked myselk using the same approach.
From outside my network using a telnet connexion i reached my mail server and
sent a mail
from: <personnal_an...@fai.com>
to: <c...@ftp.mydomain.net>
The server do really send this email but it's only a Mail Delivery System saying
"the message could not be be delivered"
...
In this mail, further, it is said :
"For further assistance, please send mail to <postmaster>"
...
I'm just wondering if all this stuff is only to get the valid <postmaster> mail
user.
- If yes, can I do something (configuring postfix) to stop this Mail Delivery
System automatic answer ?
- Must I delete this <postmaster> mail user definitly ?
Is this user not used elsewhere ?
- Can I change this postfix message ?
Thanks for yours lights and have a nice week-end.
