I've set up a mail server, using SuSe Standard Server, and while it's now working, it appears I've also got an open mail relay running. According to what I've read in the O'Reilly Postfix book, postfix is supposed to default to not be an open relay. I've check main.cf and I can't see anything that might be causing the open relay. Any ideas, as to what I might check? I've shut down postfix, until I can resolve this problem.
Why are you allowing people outside your firewall (you do have one don't you?) to come in on port 25?? If they can't use port 25, they can't use you as a relay.
They also can't send you mail. Sort of defeats the purpose (or one of the purposes) of running a mail server, doesn't it?
1) He didn't state he was running a mail server.
Yes he did. First sentence.
The term 'mail server' can be pretty ambiguous..... incoming? outgoing?
I've set up a mail server, using SuSe Standard Server,
2) If he is, he should know enough how to set up to prevent relaying.
So, lemmie get this straight ... If he HAS to ask he does not DESERVE an answer?
Well yes.... I just took a quick read of some of the comments in /etc/postfix/main.cf and there is a *LOT* of information there on dealing with relaying. Should be sufficient for most.
He pointed out that his docos said is should not relay but he believes it was, and that's why he's asking. Christ, he purchased O'Reilly as well as SuSE so you can hardly accuse him of not RTFM...
I guess he didn't read the main.cf comments. That's where the changes are made. BTW, you;re bitching a lot a me... where are all of *YOUR* helpful comments???????
One learns by doing. I suppose you sprung fully onmicient from the womb?

3) Since he is sending mail from rogers.com, it wouldn't appear that he is running his own mail server.....
Perhaps he had the sense to shut down when he realized it was a open relay...
Not so.. I've been corresponding off-list and he is doing this for some company.... not from his own machine.
It is for a company and I did shut down postfix, when I realized that it might be relaying. Incidentally, that reply to you, was accidentally sent off list. In this mail list, I have to change the reply to address. Sometimes I forget.
Cut him some slack. If you don't want to offer help, why read this list?
Gee... once again... just what did you add to help him out... huh?? huh??
