SpamAssassin overview

SpamAssassin is a mail filter which attempts to identify spam using a variety of mechanisms including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases.

Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited commercial email. Once identified, the mail can then be optionally tagged as spam for later filtering using the user's own mail user-agent application.

SpamAssassin typically differentiates successfully between spam and non-spam in between 95% and 100% of cases, depending on what kind of mail you get and your training of its Bayesian filter. Specifically, SpamAssassin has been shown to produce around 0.9% false negatives (spam that was missed) and around 0.1% false positives (ham incorrectly marked as spam). See the rules/STATISTICS*.txt files for more information.

Something seem wrong with this download: It only downloads the creepy "MacUpdate Installer". Where's the "deadlink"-Button?

This is NOT an application that can simply be placed in your applications folder and then launch it and configure it for your pop mail account in mail.app First you have to install the developer tools and then use Terminal to go through all kinds of permutations and commands. This app is for the users who know how to use Unix and are one of the brave and fearless. Unfortunately I am not one of them although I have dabbled with Fink and X11 I am depite all my years of experience with my Macs an ingenue and dilittente nevertheless. More power to those who can use this!

Great Product - worthy of a UB upgrade. Thanks to the developer for providing this essential tool free of charge.

SpamAssassin is superb, especially when paired up with a mail server that makes good use of it. I have a Mac OS X 10.3.9 machine (not Server) on which I run the Exim mail server software, hooked up to SpamAssassin via SA-Exim. It's all free software. The mail server uses SpamAssassin to identify spam before it's accepted, so that it can refuse delivery. The result is that the spam never even appears in my junk mail folder; it's refused before it even gets to me.
