SpamProbe
SpamProbe is a spam detection program that uses a Bayesian analysis of the frequencies of terms used in the email. Because it filters email based on content rather than on general rules, it easily adapts itself to the types of email that each individual user normally receives.

Recent releases
- 18 Feb 2006 06:58
Changes: This release fixes a pair of bugs related to email messages with no lines in their bodies. Headers from email messages with no bodies were not being tokenized, and it was possible for a message with invalid MIME headers and no body to lead to a crash.
- 30 Jan 2006 12:37
Changes: This release fixes a bug in decoding malformed base64 encoded data that manifested itself in some architectures. It also corrects a typo in the online help. Some code cleanup and minor performance tweaks were added as well.
- 29 Dec 2005 10:22
Changes: Contains all improvements from the 1.3 experimental versions, including tokenization of image attachments to stop content-free image spam, native support for maildir mailboxes, and an online help system. Also includes significant performance improvements, and closes all open bugs from 1.2a.
- 19 Dec 2005 19:40
Changes: This release restores the -o suspicious-tags feature that had been accidentally removed in 1.2. It also fixes a text attachment parsing bug introduced in 1.3x1 (text attachments were effectively parsed dozens of times).
- 16 Dec 2005 11:25
Changes: This release adds support for the Maildir (qmail) mailbox format, an online help system, and two new commands: create-db and create-dir.

1.2 uses a different parser than 1.0 so there would be a benefit to updating your database using 1.2a to get the new terms found by the new parser. I don't know what "totally miserable" means to you but if you are saying that 1.2a isn't finding any spams then clearly there is a problem with your database. 1.2 is at least as accurate as 1.0 in all of my tests.
Re: Update from version 1.0a to 1.2a *very* useful, still blows it!!
Even with the correct build, when I run spamprobe find-good on my latest spam mails, I get totally miserable results compared to 1.0a! Strange! Do I have to retrain this new version with train-spam?

Re: Update from version 1.0a to 1.2a *very* useful
Nico,
Well, I made a mistake when building spamprobe. My database is Berkeley db and I somehow built it with that new hash feature enabled.
Here is the configure command, that built it correctly, I assume:
LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include/db3/ ./configure --enable-cdb --with-db=/usr/local/lib/

Update from version 1.0a to 1.2a *very* useful
Hi,
completely different experiences over here. At least when the PBL DB is used SpamProbe belongs to the fastest Bayesian classifiers. The accuracy in 1.2a is excellent as well. Even better in 1.3.x btw.
Regards, Nico
Update from version 1.0a to 1.2a not useful
Hallo,
spamprobe 1.2a somehow blows it completely for me. Bad, bad results, while 1.0a was and is pretty good, albeit somewhat slow.
