postfix configuration

I'm trying to modify my postfix configuration so that it will modify the sending domain. I've done this on my red hat box by setting the following in /etc/postfix/main.cf: main.cf:myhostname = www.3times25.net main.cf:mydomain = 3times25.net When I do the same on my SuSE box, it does not work. I know that there is a /etc/sysconfig/postfix configuration file on SuSE that does not exist on red hat, but I can't figure out if something there is overriding my settings in /etc/postfix/main.cf Anyone have any suggestions/insight? -- Until later, Geoffrey Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. - Benjamin Franklin
