To combat this growing problem, a number of applications and services have been developed, and SpamAssassin is one of the most effective and popular Open Source solutions. Free to use, flexible, and effective, SpamAssassin has become the most popular Open Source antispam application. Its unique combination of power and flexibility make it the right choice. This book will now help you set up and optimize SpamAssassin for your network. As a system administrator, it's down to you to implement, configure and adapt SpamAssassin to fight the Spam War. Fortunately, in SpamAssassin you chose well. Its power and flexibility make it a potent tool. However you also know that any flexible application is only as good as how it's set up and configured. This book is a compr

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 ofemail, 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

This state-of-the-art monograph presents a coherent survey of a variety of methods and systems for formal hardware verification. It emphasizes the presentation of approaches that have matured into tools and systems usable for the actual verification of nontrivial circuits. All in all, the book is a representative and well-structured survey on the success and future potential of formal methods in proving the correctness of circuits. The various chapters describe the respective approaches supplying theoretical foundations as well as taking into account the application viewpoint. By applying all methods and systems presented to the same set of IFIP WG10.5 hardware verification examples, a valuable and fair analysis of the strenghts and weaknesses of the various approaches is given.

This book constitutes the refereed proceedings of the Third International Workshop on Tools and Algorithms for the Construction and Analysis of Systems, TACAS '97, held in Enschede, The Netherlands, in April 1997.
The book presents 20 revised full papers and 5 tool demonstrations carefully selected out of 54 submissions; also included are two extended abstracts and a full paper corresponding to invited talks. The papers are organized in topical sections on space reduction techniques, tool demonstrations, logical techniques, verification support, specification and analysis, and theorem proving, model checking and applications.

This book presents a coherent description of the theoretical and practical aspects of Coloured Petri Nets (CP-nets or CPN). It shows how CP-nets have been de veloped - from being a promising theoretical model to being a full-fledged lan guage for the design, specification, simulation, validation and implementation of large software systems (and other systems in which human beings and/or com puters communicate by means of some more or less formal rules). The book contains the formal definition of CP-nets and the mathematical theory behind their analysis methods. However, it has been the intention to write the book in such a way that it also becomes attractive to readers who are more interested in applications than the underlying mathematics. This means that a large part of the book is written in a style which is closer to an engineering textbook (or a users' manual) than it is to a typical textbook in theoretical computer science. The book consists of three separate volumes. The first volume defines the net model (i. e. , hierarchical CP-nets) and the basic concepts (e. g. , the different behavioural properties such as deadlocks, fair ness and home markings). It gives a detailed presentation of many small exam ples and a brief overview of some industrial applications. It introduces the for mal analysis methods. Finally, it contains a description of a set of CPN tools which support the practical use of CP-nets.

This coherently written book is the final report on the IPSEN project on Integrated Software Project Support Environments devoted to the integration of tools for the development and maintenance of large software systems.

Also included is a comprehensive bibliography listing more than 1300 entries and a detailed index.

This book presents 12 revised refereed papers selected as the best from 32 submissions for the First International Workshop on Tools and Algorithms for the Construction and Analysis of Systems, TACAS '95, held in Aarhus, Denmark, in May 1995.
The workshop brought together 46 researchers interested in the development and application of tools and algorithms for specification, verification, analysis, and construction of distributed systems. The papers included in the book are devoted to refinement-based and compositional verification, construction techniques, analysis and verification via theorem proving, process algebras, temporal and modal logics, techniques for real-time, hybrid and probabilistic systems, and value-passing systems.

The purpose of this book is to present a project from the ESPRIT Specific Programme of European Research and Development in Information Technology, project number 6310, known as MMTCA: Multimedia Toolbox for Cooperative Applications. This project ran from 1992 to 1994, and concluded with a product which is probably of great usefulness to all business organisations. MMTCA enables managers to set up arrangements or to delegate tasks involving cooperation between people in different places using standard Windows software tools for what-you-see-is-what-I-see (wySIWIS) cooperation. MMTCA is the only product that delivers all of these points. Several trends in 1994 lead the authors to believe that MMTCA will become more important over the coming months: * the continuing popularity of personal computers and Microsoft's Windows operating system, * the growing importance of computer-supported cooperative work, and * the availability of powerful networks and satellites for wide-area communica tions. In MMTCA it is not necessary for the manager to know anything about com puter programming, but merely to have a user's working knowledge of the appli cation software (spreadsheets etc.) that is used in his office. The MMTCA approach envisages two stages where MMTCA's facilities are used: * by the manager: setting up or organising work to be done, * by the participants: carrying out the resulting tasks.

The Software Engineering and Knowledgebase Systems (SOFfEKS) Research Group of the Department of Computer Science, Concordia University, Canada, organized a workshop on Incompleteness and Uncertainty in Information Systems from October 8-9, 1993 in Montreal. A major aim of the workshop was to bring together researchers who share a concern for issues of incompleteness and uncertainty. The workshop attracted people doing fundamental research and industry oriented research in databases, software engineering and AI from North America, Europe and Asia. The workshop program featured six invited talks and twenty other presentations. The invited speakers were: Martin Feather (University of Southern CalifornialInformation Systems Institute) Laks V. S. Lakshmanan (Concordia University) Ewa Orlowska (Polish Academy of Sciences) z. Pawlak (Warsaw Technical University and Academy of Sciences) F. Sadri (Concordia University) A. Skowron (Warsaw University) The papers can be classified into four groups: rough sets and logic, concept analysis, databases and information retrieval, and software engineering. The workshop opened with a warm welcome speech from Dr. Dan Taddeo, Dean, Faculty of Engineering and Computer Science. The first day's presentations were in rough sets, databases and information retrieval. Papers given on the second day centered around software engineering and concept analysis. Sufficient time was given in between presentations to promote active interactions and numerous lively discussions. At the end of two days, the participants expressed their hope that this workshop would be continued."

Jumpstarting books provide an avenue for makers to quickly master topical knowledge! Each book starts with instructions on how to install or initialize the hardware or software needed to reach the "Hello, World" stage of getting started! The second project in the book builds on the first to use more of the hardware or software's capabilities. Later projects expand the user's knowledge into lesser-known aspects of the topic. All Jumpstarting projects are for Makers -- they provide hands-on, real-world experience in making the hardware or software do what you want it to do!
