Here's where Postfix shines as being simple to setup: you need to change only one thing to make it work "out of the box." It's been my experience that whatever configuration you get when you install Postfix is ready to go, but it needs only to know the name of your ISP's mail server. You see, Postfix is a mail server on your machine, and it speaks the same language as almost every other mail server out there on the Internet. Unless your ISP does really weird things, it should quite willingly accept your outgoing mail just like it came from within their own internal mail system in their office. Login as root, and navigate to /usr/local/etc/postfix. Open the file named main.cf with your favorite editor. A good editor will allow the display of a line number for each line of text, either in the right margin or somewhere in the display. Go down to about line 310, where you should see this: #relayhost = $mydomain #relayhost = gateway.my.domain #relayhost = uucphost #relayhost = [an.ip.add.ress] These lines are examples that you can copy, but the hashmark (#) at the front of each one prevents Postfix from reading those lines as something it needs to use. The second one is your model for most dialup connections. Your ISP should be able to tell you the specific name of the computer that handles mail on their system. Most of them use "mail.something.com" or a similar name. Recall from the installation tutorial that this is the usual nomencalture for giving a computer an identifiable name for the Internet. At any rate, whatever your ISP tells you is what goes here. If they just give you an IP number, you can use that, too, by using the last line as your model. Just replace the letters with the digits. For now, all IP addresses are a series of numbers divided into four sections by periods or dots. It's probably a good idea for your own sake to simply add a new line below these four, but without the hash mark. Save the file. Then close it, and at the command line type: postfix reload ============================================================= Therefore, if I have several email addresses that are through different ISP's, don't I have to configure POSTFIX fir each of them? Thanks for your assistance. I am really new ( as if you could not guess ) at setting up a mail system.
