Who This Book Is For

This book is aimed at technically confident users and new and part-time system administrators 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. Basic knowledge of Linux is expected.

What you will learn from this book?

  • Create an ongoing scheduled backup to recover from catastrophic loss of service in case of a major hardware or software malfunction

In Detail

Many businesses want to run their email servers on Linux for greater control and flexibility of corporate communications, 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.

This book gives you just what you need to know to set up and maintain an email server. Unlike other approaches that deal with one component at a time, this book delivers a step-by-step approach across all the server components, leaving you with a complete working email server for your small business network.

Starting with a discussion on why you should even consider hosting your own email server, the book covers setting up the mail server. 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.

Written by professional Linux administrators, the book is aimed at technically confident users and new and part-time system administrators. The emphasis is on simple, practical and reliable guidance.

Based entirely on free, Open Source software, this book will show you how to set up and manage your email server easily.

Biografía del autor

Alistair McDonald is a freelance IT consultant based in the UK. He has worked in IT for over 15 years and specializes in C++ and Perl development and IT infrastructure management. He is a strong advocate of open source, and has strong cross-platform skills. He prefers vim over vi, emacs over Xemacs or vim, and bash over ksh or csh. He is very much a family man and spends as much time as possible with his family enjoying life. Carl Taylor has worked over 20 years in the IT industry and has spent the majority of that time working on Unix type systems, mainly communications or office automation projects. He was an early user of the UseNet network and taught himself to programme in C through working on a variety of open source software. His experience covers roles including pre and post sales support, product development, end user training and management. Carl now runs his own Web Solutions development company 'Adepteo' where they specialise in intranet and workflow products building on the best open source applications available. Whilst not working or looking after his children Carl is something of a dance addict and is currently learning Latin and Ballroom and Salsa. David Rusenko was born in Paris, France, and spent most of his childhood overseas. He began working as a freelance web designer in 1996 and had his first experience with open source, a box copy of RedHat 5.2, shortly after in 1999. After six years and as many versions of RedHat, he now creates appealing web pages and devises solutions implementing high availability through clustering and alternate security models. He founded Aderes (http://www.aderes.net) in 2001, a company which provides email and web-based security solutions. His search for an appropriate Webmail platform for the company led him to Squirrelmail. Initially managing all aspects of the business, from the technical concerns to customer support, gave him the experience he now contributes to the Webmail chapter of this book. David has studied both Information Sciences and Technology (IST) and Management Information Systems (MIS) at the Pennsylvania State University. He speaks English and French fluently, and is conversational in Arabic. During his free time and vacations, he enjoys scuba diving, backpacking, playing racquetball and playing electronic music records.
