    many drawbacks
  

*by W***E on Reviewed in the United States on August 25, 2004*

A comprehensive description of the many features of SpamAssassin [SA] and how it can be integrated with the major mailing programs sendmail, postfix, qmail and Exim. Certainly, the free and open source nature of SA will appeal to some.But the problem with the book is that it never seriously analyses the many flaws of SA. The most glaring is how it used blacklists. It only applies these against various header fields. Yet it is well known that spammers forge arbitrary sender addresses. Which greatly reduces the efficacy of the blacklist.Also, the book devotes attention to how SA uses Bayesians. It says how you need a corpus of spam and one of non-spam, to train the Bayesian. Yet this has proved to be a severe constraint on actual usage. The book never says how these corpuses are to be found. In practice, this is done manually. Even worse, the book does not point out that spammers can and are poisoning Bayesians, with innocuous non-sequitur words in their messages. This means that a Bayesian must be continually retrained on new corpuses, that have been manually gathered. Very labour intensive. Few users are willing and able to do so.

    Took some thinking about configuration but works great

SpamAssassin is the immensely popular open-source spam solution for the Linux/Unix world.  This book covers version 3.0, which, curiously enough, is not included with the book.  This is pretty unusual in the open-source world since it costs very little to put a copy of the program onto CD and bind it into the book.The reasons for SpamAssassin's popularity include its high level of customizability, the ability to change the rules and the weights assigned to those rules, automatically report spam to clearinghouses, ability to interface with other resources on the internet including DNS blacklists, ability to create a whitelist, and the ability to work with a wide variety of mail systems including sendmail, Postfix, qmail, and Exim.  One of the really nice features is the ability for the system to automatically add a person to the whitelist if you send an outgoing email to that person.Of course all of this requires an understanding of how SpamAssassin works and how to configure and tweak it to get it to do what you want.  That is where this book comes in.  The author has done an excellent job of explaining not only the concepts but also the details of how SpamAssassin works and how to tweak it to work best in your environment.  This is easily one of the most clearly written and understandable books on configuring the software that I have read.  SpamAssassin is highly recommended for anyone on a Unix-like system who is considering using the program as a spam control solution.It took some time to figure out how to configure it best for my needs but my spam is down over 90% with no false positives.  Don't expect the author to spoon feed you what is best for your system, but he gives you the information to design one that works for you.
