Open friendly letter from bogofilter to qsf.

[Matthias Andree]

Andrew,

I have recently come across your qsf project.

I am speaking on behalf of David Relson and myself, who are two of the
bogofilter developers.

bogofilter is a project similar to qsf.  We describe it as "A spam
filter that's fast, trainable, and learns".  The project was started by
Eric S. Raymond and shares some of its key concepts (procmail/maildrop
integration, data base, Bayesian approaches) with qsf, it's under the
GNU General Public License.

Since September 2002, bogofilter is hosted on SourceForge.net,
http://bogofilter.sourceforge.net/.

I invite you to look at our web site and/or code, we currently have MIME
decoding (base64 and quoted-printable) and reducing HTML comments that
are used to break up tokens to deceive spam filters; we are storing our
tokens in a BerkeleyDB data base, and offer three different algorithms
(among them Paul Graham's, then Robinson's, and Robinson-Fisher) to
classify messages.

Adrian Otto hosts two bogofilter mailing lists, one for users,
bogofilter at aotto.com, one for developers, bogofilter-dev at aotto.com
(confirmed/double opt-in subscription by sending an empty mail to
bogofilter-subscribe at aotto.com or bogofilter-dev-subscribe at aotto.com),
and we have our code in SourceForge's CVS.

We'd like to ask you if you'd have general interest in joining forces
with us, possibly avoiding reinventing wheels that have been invented
before.

Looking forward to hearing from you.

Yours sincerely,
