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.

Limit amount of emails on server
I have this mail server available to my friends at campus. It works fine until recently I've noticed that its performance degraded considerable - I traced the problem, and it was due to the large amount of emails left on the server. The users of my mail server tend to leave the emails on the server after reading them and this will eventually hog the system - imagine a scenario which actually happened of a user leaving nearly 2,000 msgs on his mailbox and whenever he tries to access them, the entire server slows down to death!
How can i solve the problem? My idea is to restrict the size of the total emails left on the server to approx. 30MB and whenever a user approaches the limit, he is sent a notification via email to remove them. When the user exceeds the limit, the new incoming emails will wither replace the new ones on the server, or simply "rejected". Any programs available?
Have you looked into using quotas yet? As far as the auto email thing, I'll hunt around to see if I can find anything on that. A script writer around here would surely be able to bust something out for you in a jiffy, but unfortunately I'm not one of them
