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 got exim now for more than two years running on my server without any problem. But last week when I updated my packages (I'm using Debian unstable) something could happen.
I just realised that I cannot send mail via pine and it keeps giving an error message without any comment just a bunch of numbers and letters.
I checked around the exim and mail log files and I found this:
"2-22 06:28:29 1D3SXd-0003i1-00 Cannot open main log file "/var/log/exim/mainlog": Permission denied: euid=8 egid=8
Feb 22 06:28:29 iguana exim: exim: could not open panic log - aborting: original error above"
So I checked the permissions of the /var/log/exim/mainlog file and I found it to be set "root" as owner. So I changed it to be "mail" the owner and left anything else unchanged and this way I could send mails again.
I thought I solved the problem the only thing I didn't understand what did change the owner of the file. BUT the next they it all started again... Cannot send mail... The owner of mainlog was the root again. I played this game for three days so I got no idea what's going on.
I know this is pretty old, but did you ever figure this out? I just hit this issue and fixed it the same way, but have no idea how it was working for the past 2 years and all of sudden stopped working.
We ran across something at work on some SuSE boxes where there's a process that checks certain files/dirs against a config file, and changes permissions back to match the config file if they'd changed. I don't know if that includes ownership, but it could. I'm sorry I can't remember what the process was or the name of the config file, but hopefully this will give you something to start with.
