[CentOS] Postfix problem

Hi

   I have a CentOS 4.2 server with postfix. The problem I'm having is  
that postfix insists on using $myhostname in the from field even if I  
instruct it to use $mydomain in /etc/postfix/main.cf or even if I hard  
code the domain name into $myorigin. What am I missing?


BTW: postconf shows output shows that $myorigin is configured to use  
$mydomain,  or the domain name itself ...
