Introduction to Linux - A Hands on Guide

I've searched far and wide for this answer, can't seem to find a fix that works...
qpopper - don't think it's the problem, though
I am able to receive emails to my domain, no problem..I am able to send emails to other users within my domain, no problem. It's when I use my box as an outgoing mail server to an external domain that I get relaying denied error..nothing about a hostname lookup, or unresolvable host...just relaying denied. I tried adding my domain in the relay-domains file in /etc/mail like so:
with no joy...I also m4'ed sendmail.mc, but I didn't see much in there about smart relaying, which is what I saw in several places to do.
I ran into this with RH 7.1, but can't remember how I ended up fixing it. My goal is that my local users can use the server as an outgoing mail server after logging in with their pop client.
any ideas? I feel it must be something minor, just can't figure out what.
I'm also running webmin, so if anyone knows of a way to set it up in that I'm game.
I couldn't really tell you - I don't know much about sendmail.. probably just enough to be dangerous. But from the two seconds I glanced through that paragragh, it looked like this file what to allow which domains to allow on your side of the network, not what your sending to.... but I could be wrong. If that isn't the case, then yea I'd try what you said, or maybe *.* or add all the basic, *.com, *.net, *.gov, *.org ..
As I recall, you have to use the access.db / makemap to enable it to relay from other machines.
I am having a related problem, where I cannot telnet to the machine on port 25. This is a new install and about a year since I last dealt with it. If anyone is familiar with Rh 7.2 and can assist, would be appreciated.
