New SpamAssassin Book Released by Packt

As a busy administrator, you know that Spam is a major distraction in todays network. The effects range from inappropriate content arriving in mailboxes, to contact email addresses placed on a website being deluged with unsolicited mail, causing valid enquiries and sales leads to be lost, wasting employee time. The perception of the problem of spam is as big as the reality.

In response to this growing problem, a number of free and commercial applications and services have been developed to help network administrators and email users combat Spam. Free to use, flexible, and effective, SpamAssassin has become the most popular open source antispam application. So what makes SpamAssassin the right choice for your network? Effectiveness and configurability for me explains Alistair McDonald, author of SpamAssassin: A Practical guide to Configuration, Customization and Integration. SpamAssassin works pretty well out of the box, but a small amount of time spent with it can reap great rewards. Typical figures quoted are 80% effectiveness out of the box, and 95% with some minor customizations.

SpamAssassin allows external Spam filtering services to be integrated. It uses a plug-in approach so that it’s easy to add support for a new technique when SURBLs came in, a SpamAssassin plugin was developed to use them. Now, the plugin is part of the main SpamAssassin distribution. The SpamAssassin community reacts quickly to changes in spam, and new rules or plugins are available very quickly. It’s not just in spam filtering that SpamAssassin excels, it’s also very flexible in how it’s configured. If you want all users to share spam definitions, it’s easy to do. On the other hand, if you want all users to use individual settings, again, it’s easy. Or a group of users can share settings, while others have their own. Flexibility extends to trapping spam. If you are bothered by a particular type of spam, you can write your own rules to detect it or you may find that someone else has already published a third party ruleset that deals with it.

Alistair McDonalds book is a comprehensive guide to the features, options, and implementation strategies you need to get the most of out SpamAssassin, helping you to set up and optimize it for your network.
