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 can't send or recieve mail with postfix. I don't get any errors, I just get nothing. When I send mail it goes into a black hole. I have a postfix MTA behind a firewall. It forwards mail on port 25 to the mail server. Here is main.cf file.
