Bogofilter is a mail filter that classifies mail as spam or ham (non-spam)
by a statistical analysis of the message's header and content (body). The
program is able to learn from the user's classifications and corrections.
The statistical technique is known as the Bayesian technique and its use
for spam was described by Paul Graham in his article "A Plan For
Spam". Gary Robinson, in his weblog Rants, suggests some refinements for
improved discrimination between spam and ham. Bogofilter's primary
algorithm uses the f(w) parameter and the Fisher inverse chi-square
technique that he describes.
Bogofilter is run by an MDA script to classify an incoming message as spam
or ham (using wordlists stored by BerkeleyDB). Bogofilter provides
processing for plain text and html, supports multi-part mime message with
decoding of base64, quoted-printable, and uuencoded text and ignores
attachments, such as images.
Bogofilter is written in C. Supported platforms: Linux, FreeBSD, Solaris,
OS X, HP-UX, AIX, ...
