spam in lost productivity and burned bandwidth is astronomical. While society is grappling with a solution to the burgeoning crisis of spam proliferation, the pressure is on system administrators to find a solution to this
massive problem in-house. And fast.
Sys admins can field scores of complaints and spend months testing software suites that turn out to be too aggressive, too passive, or too complicated to setup only to
discover that SpamAssassin (SA), the leading open source spam-fighting tool, is free, flexible, powerful, highly-regarded, and remarkably effective. The drawback? SpamAssassin's lack of published documentation.
SpamAssassin by Alan Schwartz, is the only published resource devoted to SpamAssassin and how to integrate it effectively into your networks. This clear, concise guide clarifies the installation,
configuration, and use of the SpamAssassin spam-checking system (versions 2.63 and 3.0) for Unix system administrators using the Postfix, Sendmail, Exim, or qmail mail servers, helping administrators make the right integration
decision for their particular environments.
It covers concrete advice on how to:Customize SpamAssassin's rules, and even create new ones Train SpamAssassin's Bayesian
classifier, a statistical engine for detecting spam, to optimize it for the sort of email that you typically receive
Block specific addresses, hosts, and domains using third-party blacklists like the one
maintained by [...].
Whitelist known good sources of email, so that messages from clients, coworkers, and friends aren't inadvertently lost.
Configure SpamAssassin to work with
newer spam-filtering methods such as Hashcash ([...] and Sender Policy Framework (SPF).
Sys admins, network administrators, and ISPs pay for spam with hours of experimentation and tedious junk
email management, frayed user tempers, and their sanity. SpamAssassin, together with this essential book, give you the tools you need to take back your organization's inboxes.

informative--recommended for spam-filtering beginners and experts alike." --Justin Mason, SpamAssassin development team
