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.

I am trying to setup a mail server and I seem to be having some problems. I am using Postfix and it seems to be running just fine. My problem is that I CAN send emails out of the box, like to hotmail, but I cannot receive them. I am basically using the default settings for postfix, except for a few changes in /etc/hosts and /var/spool/postfix/etc/hosts.
I tried pinging my server from an outside source and it pinged just fine.
I also tried sending a local email to one of the other users on my system and apparently local emails both send and receive. I checked out the main.cf file and I think that all of the default stuff should work. Is there anything that I definitely need to change?
Does Postfix send and receive emails or does it use other programs to do some of the work? If so, maybe it's the program that handles fetching outside emails coming in?
I setup postfix about two years ago and I had to add a few lines to the main.cf file for smtp authentication, that will allow you send email from outside your subnet. I don't know for sure if that's the problem your having, but in case it is you can find lots of how to info on the net. Check out this link..
As trickykid says, the error message will probably indicate exactly where things are going wrong, so perhaps you could post some of the text.
Postfix can handle the whole process, but if you are using your distro's default configuration it's probably locked down to some extent; e.g. to deliver mail from foreign systems to local spools may require 'inet_interfaces' to be edited in main.cf, and 'mydestination' for Postfix to accept mail for the domain itself.
Try changing your main host and domain name in your configuration to elderainmud.com and or mail.elderainmud.com as I tried sending email to your address and it was returned "host unknown" almost immediately. Its either that on your server or your MX records are not setup correctly.
Yes, I did try what you mentioned in the last post and nothing seemed to work. I am completely new to linux so a lot of stuff that you guys say just goes over my head. I tried modifying a few things in main.cf and master.cf and nothing seemed to work at all. I checked my configuration in my Mandrake Control center and the servers Host name is set to elderainmud.com.
I checked my MX records and they are 'elderainmud.com points 1st to domain elderainmud.com' I also did a 2nd one 'mail.elderainmud.com points 2nd to domain elderainmud.com' and it didn't seem to affect anything.
Maybe if I post my main.cf file on the internet maybe one of you could point out any errors?
