Re: [spambayes-dev] pgsql
by Mike Miskulin March 30, 2006

Hi, About a month ago I posted on the regular list in regards to trying to get spambayes to work with mysql and postgresql. I can report that things are mostly, but not entirely well. I have been working on a win XP home system. First, I'd like to suggest the following or similar be added to classifier.py around abouts line 320: if ((hamratio + spamratio) > 0) : prob = spamratio / (hamratio + spamratio) else: prob = 0.5 I had a number of instances after resetting the database that I bombed on div by 0 errors. I have attached a few pdf's capturing a few errors that seem to be typical while using postgresql. (I only used mysql long enough to determine it functioned so can't say for sure if this would occur there too). I've not been able to track this error down, its a bit beyond me. As you can see it has happened immediately after training a group of messages as well in the course of normal operation. This error how ever does not appear to be 'fatal'. A simple stop/restart of the spambayes service and things run again. A more serious error which is temporarily fatal occurs when a situation of token in more spam(ham) than spam(ham) trained. Again, I've not tracked down the why of it happening. But I have noticed a few things: 1- the keyword that it most offen happens to is 'Subject' 2- if it is multiple keywords, then it has happened after training on messages. 3- bouncing a message to the service (ie spambayes_ham@localhost) that has not been previously seen (ie, to train quicker instead of waiting for new messages to arrive) seems to screw things up. Maybe not after the first message, but not long after. Note I have also seen situations where the service stops accepting messages. Now while this is annoying to have happen, unlike with the 'normal' way of using spambayes, one can easily go into the database and 'fix' the problem - at least to the extent you no longer have a nspam > spam trained situation. While adjustments to the database may be arbitrary if you are off by more than 1, if you have a large number of trained messages it shouldn't have a material effect. And at least one need not start completely over. Well I hope this all is of some use to you guys. If you have any questions please email me directly as I did not subscribe to the devel list. Cheers Mike

SpamBayes appearance in NetGuide (NZ Magazine)
by Tony Meyer March 27, 2006

March 27, 2006

Just a FYI for anyone interested: A friend pointed out to me the other day that SpamBayes was featured in NetGuide, which is probably the most well-known magazine of its type in New Zealand. I don't normally get it (it's very newbie stuff), but got a copy of this issue (#109, April 2006). One of the cover stories is a five-page article "How to kill spam with two free filters: out, damned spam!)". It talks about Thunderbird's built-in filtering and the SpamBayes Outlook plug-in (which is also on the included CD). It doesn't really review either, concentrating on "how to" guides for each (the implication is that these are the two best options, I suppose, rather than the others included on the CD and not mentioned in the article). Now that we've got some fame in New Zealand, there's no stopping us <wink>. Maybe I should hurry up on the oft-promised 1.1a2 :) =Tony.Meyer

assertion error in sb_filter.py
by paul sorenson March 22, 2006

March 22, 2006

I have been using spambayes for ages with the pop proxy and have just migrated my server to IMAP. I am currently running sb_filter from a procmail script and getting the traceback in the procmail log below. For training I have just been running sb_filter.py -g/-s from the command line on appropriate mailboxes. I notice when I run sb_filter.py the file modified date on ~/.hammiedb changes but the size doesn't. I have presumably missed something. In ~/hammierc I have: [Storage] persistent_use_database = True persistent_storage_file = ~./hammiedb Procmail log: procmail: [15664] Wed Mar 22 18:47:51 2006 procmail: Assigning "MAILDIR=/home/pms/mail" procmail: Assigning "INCLUDERC=/home/pms/.procmail/rc.spambayes" procmail: Locking "hamlock" procmail: Executing "/usr/bin/sb_filter.py" Traceback (most recent call last): File "/usr/bin/sb_filter.py", line 257, in ? main() File "/usr/bin/sb_filter.py", line 248, in main action(msg) File "/usr/bin/sb_filter.py", line 180, in filter return self.h.filter(msg) File "/usr/lib/python2.4/site-packages/spambayes/hammie.py", line 109, in filter prob, clues = self._scoremsg(msg, True) File "/usr/lib/python2.4/site-packages/spambayes/hammie.py", line 38, in _scoremsg return self.bayes.spamprob(tokenize(msg), evidence) File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 190, in chi2_spamprob clues = self._getclues(wordstream) File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 493, in _getclues tup = self._worddistanceget(word) File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 508, in _worddistanceget prob = self.probability(record) File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 308, in probability assert hamcount <= nham AssertionError procmail: Program failure (1) of "/usr/bin/sb_filter.py" procmail: Rescue of unfiltered data succeeded procmail: Unlocking "hamlock"

How to implement my own classifier?
by Markus Weimer March 12, 2006

March 12, 2006

Hi, at the moment, I am starting research in the field of spam filtering and would like to use SpamBayes as a base. I looked into the code and as far as I can tell, I need to reimplement the classifier.Classifier class if I wanr to plug-in my own classifier. I am unsure about which methods this class must provide to be compatible with the rest of SpamBayes and especially the test tools. Can someone give me a clue here? Thanks in advance, Markus
