I'm a webmaster for a what is currently a small site hosted by a web hosting company. Plans are well underway to move to our own dedicated server, so I can have more control over what I can and can't do. Unfortunately, all the linux stuff is new to me.
Problem: postfix setup eludes me. -- once running, Postfix "sendmail" is only found if I am root, and once I do a "sendmail" command, the email never makes it out.
Clue: /var/log/maillog has multiple entries for "Connection refused" -- having the expected increasingly defered timestamp interval at each attempt.
Despite the "just change these three fields and VOILA!" description of the setup, I'm way to green and new to Linux, and some of even the basic assumptions can't be made.
From what I understand so far -- sendmail comes up on boot of my RedHad 8.0 server and my RedHat 9.0 local development box. I can stop sendmail via "service sendmail stop" and start Postfix via "service postfix start" --- I'll get that on startup soon -- not the priority. For now the discussion need to be relative to the server only, as I'm having trouble getting my development box to see the internet.
I have webmin running on the server -- if that helps.
rpm -qa reports the following mail oriented packages:
As always -- any help is appreciated.....
