I need help in setting up Postfix. I have read several different man pages, HOW To's and still have questions. If anyone has a link to a step by step guide to configuring Postfix I would appreciate it. One of the issues I am having is when I edit the main.cf file do I replace everyinstance of $myhostname and $mydomainame with my settings or do I just edit them the first time. It would really help if I could see it done once correctly so that I know I am on the right page.
