Many businesses want to run their email servers on Linux, but getting started can be complicated. The attractiveness of a free-to-use and robust email service running on Linux can be undermined by the apparent technical challenges involved. Some of the complexity arises from the fact that an email server consists of several components that must be installed and configured separately, then integrated together. Unlike other approaches that deal with one component at a time, this book gives you a basic knowledge across all the server components, leaving you with a complete working email server for your small business network.Based entirely on free, Open Source software, you will see how to protect your server from spam and viruses, offer web access for remote access, and secure your installation with regular backups.
What you will learn from this book
- Setting up and running a Linux-based email server
- Key information about installing, configuring, and using PostFix, Courier, SquirrelMail, ProcMail, ClamAV, and SpamAssassin
- Securing and protecting your installation from viruses, spam, intruders, and hardware failure
Approach
The book takes a practical, step-by-step approach to working with email. We start by establishing the basics, so that your users can send and receive their email in their favourite email client. We then move on to look at providing web access, so that users can access their email out of the office. After this we look at the features you'll want to add to improve email productivity: virus protection, spam detection, and automatic email processing. Finally we look at an essential maintenance task: backups.
Who this book is written for
This book aimed at 'unofficial' sysadmins in small businesses, who want to set up a Linux-based email server without spending a lot of time becoming expert in the individual applications.

GNU/Linux is an immensely popular operating system that is both extremely stable and reliable. But it can also induce minor headaches at the most inopportune times, if you're not fully up to speed with its capabilities.
A unique approach to running and administering Linux systems, Linux Annoyances for Geeks addresses the many poorly documented and under-appreciated topics that make the difference between a system you struggle with and a system you really enjoy. This book is for power users and system administrators who want to clear away barriers to using Linux for themselves and for less-trained users in their organizations.
This book meticulously tells you how to get a stubborn wireless card to work under Linux, and reveals little-known sources for wireless driversand information. It tells you how to add extra security to your systems, such as boot passwords, and how to use tools such as rescue disks to overcome overly zealous security measures in a pinch. In every area of desktop and server use, the book is chock full of advice based on hard-earned experience.
Author Michael Jang has spent many hours trying out software in a wide range of environments and carefully documenting solutions for the most popular Linux distributions. (The book focuses on Red Hat/Fedora, SUSE, and Debian.) Many of the topics presented here are previously undocumented or are discussed only in obscure email archives.
One of the valuable features of this book for system administrators and Linux proponents in general is the organization of step-by-step procedures that they can customize for naive end-users at their sites. Jang has taken into account not only the needs of a sophisticated readership, but the needs of other people those readers may serve.
Sometimes, a small thing for a user (such as being able to play a CD) or for an administrator (such as updating an organizations' systems from a central server) can make or break the adoption of Linux. This book helps you overcome the most common annoyances in deploying Linux, and trains you in the techniques that will help you overcome other problems you find along the way.
In keeping with the spirit of the Annoyances series, the book adopts a sympathetic tone that will quickly win you over. Rather than blaming you for possessing limited Linux savvy, Linux Annoyances for Geeks takes you along for a fun-filled ride as you master the system together.

While Mac OS X garners all the praise from pundits, and Windows XP attracts all the viruses, Linux is quietly being installed on millions of desktops every year. For programmers and system administrators, business users, and educators, desktop Linux is a breath of fresh air and a needed alternative to other operating systems.The Linux Desktop Pocket Guide is your introduction to using Linux on five of the most popular distributions: Fedora, Gentoo, Mandriva, SUSE, and Ubuntu. Despite what you may have heard, using Linux is not all that hard. Firefox and Konqueror can handle all your web browsing needs; GAIM and Kopete allow you to chat with your friends on the AOL, MSN, and Yahoo! networks; and the email programs Evolution and Kontact provide the same functionality as Microsoft Outlook, with none of the cost. All of these programs run within the beautiful, feature-packed, and easy-to-use GNOME or KDE desktop environments.
No operating system truly "just works," and Linux is no exception. Although Linux is capable of running on most any computing hardware that Microsoft Windows can use, you sometimes need to tweak it just a little to make it work the way you really want. To help you with this task, Linux Desktop Pocket Guide covers essential topics, such as configuring your video card, screen resolution, sound, and wireless networking. And laptop users are not left out--an entire section is devoted to the laptop issues of battery life, sleep, and hibernate modes.
