The annoyance factor for individual users whose email is crammed with pitches for pornography, absurd moneymaking schemes, and dubious health products is fierce. But for organizations, the cost of 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 Spamcop.net. * 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 (www.hashcash.org) 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. "Detailed, accurate and informative--recommended for spam-filtering beginners and experts alike." --Justin Mason, SpamAssassin development team

The best clinicians take into account the life challenges of their patients when planning their care, a process Drs. Weiner and Schwartz refer to as "contextualizing care." Failures to contextualize care, when they results in care plans that seem appropriate from a narrowly clinical perspective but are nevertheless unlikely to achieve their intended aims represent "contextual errors." Prescribing a medication a patient cannot afford when a less costly alternative is available would constitute such an error. Drawing on two decades of research including analysis of nearly 10,000 audio recorded medical encounters, the authors document an unmeasured dimension of quality: the extent to which clinicians attend to patient context, and its substantial implications for health care outcomes and costs. Listening for What Matters provides a comprehensive overview of research and quality improvement efforts to address the problem of contextual error. This second edition has been revamped and updated to include studies testing clinical decision support tools in the electronic medical record, medical student and resident trainee educational interventions, and an audio-recording based quality improvement program within the Department of Veterans Affairs. This book is a must-read for physicians, other health care professionals, policymakers and administrators, medical students, and medical educators.
