Bogofilter-0.14.1 - New Current Release (David Relson)

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, ...

Bogofilter version 0.14.1 has been released on SourceForge,
http://sourceforge.net/projects/bogofilter.
0.14.1 - Adds token degeneration capability (use "bogofilter -h" for help)
and changes exit codes from 0=spam, 1=ham, and 2=error to 0=spam, 1=ham,
2=unsure, and 3=error; and fixes several minor bugs with 0.14.0.1
See files NEWS-0.14 and RELEASE.NOTES-0.14 for the details.

=================
0.14.1 2003-07-31
* Implemented named exitcodes, with Unsure having its own value (2)
and changing the value for error from 2 to 3.
* Initial release of token degeneration code.
* Revised lexer pattern to better recognize encoded tokens.
0.14.0.1 2003-07-23
* Fix problem with encoded text.
* Fix handling of absolute paths.
* Fix defect in base64 decoding that can cause segfaults.
* Bogoutil now complains before exiting when it can't open a
file.
* Updated bogominitrain.pl to work with combined wordlists.
0.14.0 2003-07-22
* Initial release of code allowing bogofilter to use a single,
combined BerkeleyDB database for storing both ham and spam tokens.
The file is named wordlist.db
* Default wordlist mode is single, combined wordlist.
File wordlist.db contains all spam and ham tokens.
* Bogofilter and bogoutil detect whether one or two wordlists are in
BOGOFILTER_DIR and use the appropriate wordlist mode (combined or
separate).
* Added tdb (trivial database) support.
* Decode encoded text in header lines.
* Updated contrib/bogominitrain.pl prints more info and can save
messages used in training.
* Bogofilter's -V output now includes algorithm and database info.
* Miscellaneous documentation updates.
