Hello everybody,

First of all, sorry for my bad English. I'm newbie to the mailing list and
to Postfix. I tried to set-up a secure mail server based on postfix but it
seems that my configuration has some serious problems. I already tried
tutorials from postfix.org and searched through archives but I'm not able to
set up properly the server to not relay.

I have a domain "mydomain.com" and would like to deliver mail only to valid
users of this domain (users are in mysql database). Other mails should be
directly deleted by postfix.

Can anybody look at my configuration and point me to the error? Thanks in
advance.

Here is my configuration:

My system is Linux Mandrak 9.1 2.4.21-0.13mdk #1 Fri Mar 14 15:08:06 EST
