Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

k, I got it to stick finally. In case anyone else comes accross this. I had to edit two files. the /etc/sysconfig/network and the /etc/hosts. I'm not too sure if I needed to edit the hosts file, but it works.
Your domain name and any other domains you wanna receive mail for. This doesn't mean that you WILL recieve the mail, it simply means you'll allow it. You won't relay for spam though if you don't specify their domain, that's the nice part.
Your domain, your hostname and any hosts on your network or domains you wanna recieve mail for.
# The mynetworks parameter specifies the list of networks that are
# local to this machine. The list is used by the anti-UCE software
# to distinguish local clients from strangers. See permit_mynetworks
# and smtpd_recipient_restrictions in the file sample-smtpd.cf file.
# The default is a list of all networks attached to the machine: a
# complete class A network (X.0.0.0/8), a complete class B network
# (X.X.0.0/16), and so on. If you want stricter control, specify a
# list of network/mask patterns, where the mask specifies the number
# of bits in the network part of a host address. You can also specify
# the absolute pathname of a pattern file instead of listing the
# patterns here.
#mynetworks = 220.127.116.11/28, 127.0.0.0/8
so, what I THINK this is saying is I have to put the LAN ips for my other computers, and my router? plus "/a number"??
Yes you do, that's for relaying If you don't your computers on your network cannot send email through you or recieve it. However... You also have to put your domain name/IP (if you have no domain) for the same reason
Those numbers are subnet masks, it confuses the he!! outta me honestly. I just don't bother with it most of the time, if you've got a massive network or are really curious... nah, nevermind, I'll find it for you and post up the page that has all the answers on that 'last number' brb
As for putting it after your no-ip.com bit, nope. Just for local networks, you'll see..
okay, so...that's it? I'm done? Now what? How do I set up email addresses? Or, wait a minute, in order to set up email addresses i have to set up user accounts? Like, there's already a firstname.lastname@example.org, no matter what?
Purty much. Check /etc/aliases OR /etc/postfix/aliases and read up on the man page. But basically yeah, create user accounts and you are done. To alias something like: Spam@whatever.com
You just have to add it to the aliases file, something like
IF user Bill is a real user Then bill will recieve all mail sent to Spam. Nice actually. Then... After adding to the aliases file, you want to run:
To save the changes, you might need to specify the aliases file, but that'll all be covered in the man page and if you have questions, POST EM UP!!!
okay, so....that seems a little too far for me, I want to send and receive some email, to make sure the things working right (and i didnt screw anything up in the process) How do I go about setting up the account in something like Evolution? So, I go to add a new user, and it fills in the blank automatically. email@example.com What's that about, I thought it would just be root@domain?? Also, on the next page it asks for "server type" is it pop?
