Bogofilter is a mail filter that classifies email 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, RISC-OS, OS/2, ...

Caution: If upgrading from an old version and skipping several
intervening versions of bogofilter, be smart and verify that the new
version is working for you before putting it into production.
Bogofilter's developers recommend that you run a few manual command
line tests. Use options, config files, and wordlists from your
production environment. This will help ensure that the new version of
bogofilter is working properly.
0.92.6 2004-08-22

* Expanded discussion of long options in bogofilter's man page.
* Added "-QQ" option to bogofilter to display extended parameter list.
* OS/2 compatibility changes (contributed by Yuri Dario).
* Removed obsolete test output files - combined.out, separate.out, and
degen.out

option --with-libdb-prefix rather than obsolete --with-db.
* Added "--wordlist" to bogofilter's help output.
* Minor clean-ups for bogofilter's help output.

* Revise enums and regression tests for new format characters
%A, %I, %Q.
* Strip bogogrep_static executable to reduce binary rpm size.
* Remove initialize() function in bogoconfig.c and use
lexer_init() in lexer.c, which provides same functionality.
0.92.2 2004-07-11
* Use an explicit inputs/outputs directory list to avoid shipping test
files in those directories.
* Miscellaneous cleanups, removed 'degen' code remainders.
* Formatting character changes:
'%A' is now the message's IP address.
'%I' is now the Message-ID.
'%Q' is now the Queue-ID.
* bogofilter-faq.html:
corrected editting error that deleted "asian spam" question
added answer to "multi-user" question.
* Fix self-test suite ("make check") when bogofilter is compiled
with QDBM or TDB as the data base engine.
* Remove obsolete '-f' from t.valgrind, too.
0.92.1 2004-07-01
* Remove 'g', 'r', and 'f' from bogofilter's OPTIONS list as
there's only one scoring algorithm.
* Removed obsolete occurrences of '-g' and '-f' from
regression tests.
* Revised README file.
* French version of FAQ updated.
* Rewrote code for identifying message's originating IP address.
* Changed name of variable 'ipaddr' to 'msgaddr'.

* Added ESF options to bogofilter's and man page.
* Revised man pages' description of multi-parameter options.
* t.lock3 regression modified for solaris shell compatibility.
0.91.4 2004-06-20
* Fix abort during db_open (ds_open wasn't first calling
ds_init).
* Added regression test t.lock3 for this fix.
* Revise datastore and database levels so that each level
calls its own init() and cleanup() routines.
0.91.3 2004-06-15
* Added format specification '%I' to allow logging of the IP
address from which an email was received.
* Avoid "Invalid buffer size, exiting." problems by discarding
text from an excessively long html tag.
0.91.2 2004-06-11
* FAQ updated with info on multiple wordlists and ignore
lists.
* FAQ updated with info on building as non-root user.
* Bogofilter's creation of new wordlists now includes
.WORDLIST_VERSION token.
* Fix erroneous double opening of wordlists specified on
command line.
* Corrected tests so that "make check" passes with qdbm and
tdb.
* Fix included GSL compile for compilers that do not support
"extern inline", such as Compaq C V6.3.
0.91.1 2004-06-04
* Use named constants for wordlist 'type' attribute to
distinguish open modes of READ, WRITE, and CREATE so
bogofilter will include .WORDLIST_VERSION in new database.
* Add DS_LOAD flag so bogoutil won't add .WORDLIST_VERSION
* Modify regression tests to use bogoutil to create empty
wordlists (as needed).
* Fixed registration. When multiple wordlists are specified,
registration is to first regular wordlist.
* Added regresstion test for multiple wordlists.
