Hello, I am try to set up postfix as a relay to an internal MX. It will run with MailScanner and will not have any local mailboxes. After spending some time with the cf and config files, I cannot tell which files are actually controlling postfix, that is, main.cf, main.cf.SuSEconfig, or /etc/sysconfig/postfix. Initially, I was modifying main.cf directly, but, as I was told, this was not the best solution on Suse. After removing the main.cf file and running SuSEconfig, SuSEconfig replaced the main.cf with a back up, although I still get the following error when running SuSEconfig; Executing /sbin/conf.d/SuSEconfig.postfix... *** WARNING *** Found /etc/postfix/main.cf.SuSEconfig, exiting... *** WARNING *** ~~~ Using 'rcpostfix restart' spits out the following error; Shutting down mail service (Postfix) done Starting mail service (Postfix)postconf: warning: My hostname postmaster is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf done postmaster:/etc/postfix # postconf: warning: My hostname postmaster is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf ~~~ I can telnet to it via port 25 so it is running. At this point, however, I have no idea which file I modify is actually affecting postfix's behavior. Any help with this would be greatly appreciated. Thank you in advance, James
