The following is the output of a bogofilter scan of an obvious spam mail. The Ham result seems to result from the "nan" values. Where do these come from and how do I fix it?

Training with ham and spam yields a wordlist that indicates how often individual words (tokens) occur in ham and in spam. For a simplified example: if "xyzw" occurs in 10% of your ham and in 20% of your spam, then a message with "xyzw" is twice as likely to be spam as it is to be ham. If you keep training with the same spam you skew the results -- which is not recommended. I don't really see biasing a spam message as spam to be particularly problematic. If indeed a particular word ought to be hammier, then it will become so in the course of training your hams.

The word r-e-p-l-i-c-a without dashes of course is in the subject line of each. I always classify them as spam manually. For some reason bogofilter misses them. Is there a way that I can manually put this word in the bogofilter criteria? I can set up my own filter in Kmail but that seems to negate the need for an adaptive spam filter. John Culleton 2008-09-08T14:03:42 http://comments.gmane.org/gmane.mail.bogofilter.general/11278 I use bogofilter integrated with Kmail. Every day my spam folder fills with properly trapped spam. Some of it is trapped by bogofilter, and some is caught by me manually. Once a week cron runs the following line: 10 4 * * 1 /usr/local/bin/bogofilter -sv -B /home/safe/Mail/spam/cur>/dev/null (It is really all one line.) Now I am considering emptying out the spam folder and starting a new collection. But when bogofilter runs again on Monday morning will I lose all the spam-finding benefits already accumulated from the formerly identified spam items I just deleted? In other words is emptying out the spam folder a safe action? John Culleton 2008-09-06T16:23:34 http://comments.gmane.org/gmane.mail.bogofilter.general/11272 Hi, First of all I have to say I'm quite pleased with bogofilter. Switched from spamprobe, and it seems faster; and after getting acquainted with it I like the 3-way politics with "unsure". I'm using qdbm as backend. Apparently it is not developed anymore in favor of a successor tokyocabinet <http://tokyocabinet.sourceforge.net/>. Are there any plans to support tokyocabinet in the future? c Christian Ebert 2008-08-22T18:06:06 http://comments.gmane.org/gmane.mail.bogofilter.general/11270 Following Nigel's how-to and philosophy I am now using "cron" to automatically handle bogofilter actions off KMail. Recall : . "Spam" folder contains manually handled messages of spam type ; mainly used at the very beginning to start training bogofilter and then each week through cron automatic action. . "NonSpam" folder contains manually handled messages of ham type ; mainly used at the very beginning to start training bogofilter and then each week through cron automatic action. . bogofilter filtering is piping messages to "inbox", "spam" or "unsure" folders depending of recognized type (spam, ham or unsure) ; all these folders but "inbox" folder have a 30 expiration period. . it is up to the user to check from time to time : - content of "inbox" folder to move spam messages not correctly detected to "Spam" folder, - content of "spam" folder to move ham messages not correctly detected to both "inbox" and "NonSpam" folders, - content of "unsure" folder to move spam messages not correctly detected Daniel Moyne 2008-08-22T12:24:15 http://comments.gmane.org/gmane.mail.bogofilter.general/11245 I scrupulously followed Nigel's how-to with all these folders : Spam NonSpam nonspamnew spam unsure in KMail (kde-4) Apprently everything works fine except that all "unsure" prefixed in subjet as ???UNSURE??? end-up in my inbox folder though fliter-4 is upposed to get them dumped into folder unsure ! Regards. Daniel Moyne 2008-08-08T22:55:43 http://comments.gmane.org/gmane.mail.bogofilter.general/11241 I had been using it with Sylpheed-Claws, and liked it very much. Due to some friends sending me html mail, I've recently switched to Icedove (aka Thunderbird). I read in the faq for bogofilter that "Bogofilter is known to work with kmail, mozilla-mail, mutt, pine, sylpheed-claws, thunderbird. A google search will help you find more information on using bogofilter with the mail program you use." I did try a google search, and a subsequent cuil search, and, alas, I have found nothing about how to set up bogofilter with thunderbird. So, how is this done?

Recently however I've been getting around 20 mails per day that contain a short bogus news item in the subject and body. These beat bogofilter with ease since they do not contain any of the usual spam keywords. Also every mail seems to be different, so they also resist new bogofilter training. See below for some examples of such mails. I've been wondering if anyone has found a reliable way of fighting this new annoyance. Thanks Tomaž Šolc Examples (each mail contains one such statement in subject and one in body plus an URL). They are plain-text mails with random user agents.

I'm currently trying to setup bogofilter on a debian 3.1 system. I compiled it by hand and tied it into postfix as mta. From there, a simple script is called with the line bogofilter -p | sendmail -i "$< at >" . I havn't altered the configuration file yet. What happens, is, that the header of incoming emails is cut off after the to: tag, where a undisclosed-recipients: is added. All tags afterwards are gone, so my mail client e.g. shows a "(no subject)". I removed the call to bogofilter by leaving the sendmail -i "$< at >" call alone, and the header arrives correctly. Has anyone any idea where my mistake is? I doubt that this is a bogofilter bug, as I can't find any occurance of this behavior anywhere. Further, I can't get bogofilter to output anything to the syslog, neither in the postfix pipe, nor by training it from the command line. Again, any ideas here? Thanks in advance, Andreas Podgurski Andreas Podgurski 2008-07-21T12:47:06 http://comments.gmane.org/gmane.mail.bogofilter.general/11216 Have searched the web and tried the man page. I have bogofilter installed, sort of. When I click the "filter classify as spam" the message is sent to trash. The wordlist.db file is about 25 megs. Just one problem, it doesn't catch any spams. Not one. Now if there is a current guide that deals with how to install and train bogofilter in Kmail, and only that, please point me to it. The manpage tells me nothing about installing the filter in kmail. I want to start from scratch.

Bobbie, before resubscribing, please make sure that: 1. ALL automated responses go to the ENVELOPE sender (some systems record it as Return-Path, else it's only in SMTP and not visible in messages) rather than the From: address 2.

What must i've to modified in amavisd and bogofilter? And the reply was to RTFM. I have been trying to get bogofilter and postfix working, and have Read The Fine Manual over and over again. No joy at all. Mail gets delivered and as best I can tell, the wordlist gets updated as new mail comes through, but I see no headers or other guarantees that bogofilter is in the loop. And yes, I do see spam: obvious, clumsy, easily-identified spam. I slipped a logger command into the filter script to see if it ever runs, and it never seems to. Does anyone have updates to any of the existing docs, other than "works for me"? _______________________________________________ Bogofilter mailing list Bogofilter< at >bogofilter.org http://www.bogofilter.org/mailman/listinfo/bogofilter paul< at >paulbeard.org 2008-06-27T22:38:10 http://comments.gmane.org/gmane.mail.bogofilter.general/11199 could anybody help me with a tutorial, pdf o something similar?

Looking at the emails of the various 'unable to deliver' type messages, I saw what these could be filtered on, but don't know how to write up and implement the rule outside of procmail. I don't want to use procmail for this since it I think it would be an expensive routine for procmail to run. In the body of the 'unable to deliver' message, the original message is quoted. One of the lines quoted is the Message-ID: header from the original. The format of this line is always wrong as it does not contain the FQDN that our server appends to the end of the hash number , following the '< at >' symbol . So, need a rule that would parse the "Message-ID:" in the body (or attachment) and not header, and look for the < at >FQDN Is this rule already out in the wild? -p _______________________________________________ Bogofilter mailing list Bogofilter< at >bogofilter.org http://www.bogofilter.org/mailman/listinfo/bogofi .rp 2008-05-07T21:58:34 http://comments.gmane.org/gmane.mail.bogofilter.general/11168 I've just posted a new version of bogofilter-milter.pl to http://stuff.mit.edu/~jik/software/bogofilter-milter. The new feature added in this version is the ability to configure whether spam should be rejected (i.e., an error code is sent back to the SMTP client) or discarded (i.e., the client is told that the email was accepted, but then it is thrown away rather than delivered). The behavior can now be configured not only on a global level, but also based on the IP address, subnet, host name, domain name, or MX relationship of the sending server. The default configuration discards spam from MX servers of the recipient's domain, to avoid contributing to the problem of spam "blowback" caused by spammers who intentionally transmit their spam to secondary MX servers. As always, please let me know if you have any questions, comments or concerns.
