Apache SpamAssassin is an award winning, mature, wide-spectrum, extensible email filtering package deployed by hundreds of thousands of organizations worldwide.
"Apache SpamAssassin is the leading Open Source email spam filtering software package that is in use by national, regional and local ISPs, email service providers, Fortune Global 500 companies, small to enterprise businesses, all levels of the education sector, governments and private individuals," said Daryl C. W. O'Shea, Chair of the Apache SpamAssassin Project Management Committee (PMC) and Information Technology Coordinator at the Township of Tay in Ontario, Canada. "SpamAssassin is also in use at the core of many commercial offerings of premier email and spam filtering firms: with its automatic update feature, sa-update, SpamAssassin now not only saves the time of end-users, it saves the time of email administrators, further increasing the software's ROI. We're very proud that SpamAssassin has become the standard for extensible and effective spam filtering software."
Apache SpamAssassin 3.3.0 represents a major shift in how SpamAssassin rules (the actual patterns that help to identify spam) are updated. Starting with version 3.3.0, rules are now separate from the core product and are instead downloaded using "sa-update," SpamAssassin's automatic update software. This method was optional with the 3.2.x series of releases and has proven to be very popular.
SpamAssassin provides a comprehensive set of features and support for methods and standards such as text based patterns, bayesian scoring, DNS based black and white lists, DKIM and SPF sender authentication, and email signature clearing houses. The software utilizes a principle of identifying multiple reasons for classifying an email as spam to improve accuracy and decrease the chance of legitimate emails being incorrectly identified as spam.
Les Tutkaluke, President of netGUARD Solutions said, "NetGUARD Solutions has been utilizing SpamAssassin for 8 years starting with version 1.0. The advanced e-mail scanning functions within the processing engines of netGUARD Solutions manages in excess of 75 million messages per day for our vast customer subscriber base. SpamAssassin is an integral and admirable addition to our filtering system and is a significant part of the accurate identification of unwanted e-mail. The success of netGUARD Solutions is directly tied to SpamAssassin and the solid programming within it."
"Over the past 365 days, SpamAssassin has blocked 516,975 unsolicited junk mails while letting through 85,032 clean ones. Without SpamAssassin email would simply be unusable. It is an essential component to our business activities," said Jean-Yves Avenard, SysAdmin at Hydrix Pty Ltd, Australia.
