Author/Date Bayesian Filtering
10/08/2005 11:21am

I've not been able to get the bayesian filtering to work. I've had it set to both training mode and live mode, but neither of them seems to work. I've classified 258 messages as spam, but the same ones just keep popping up. Any advice would be appreciated.

Is there some files with the extension ".wdb" in your scribe folder? (How big are they?)

Are you using the -o option to set the options file path?

There is a spamwords.wdb and it is 1k. I'm not using any command-line options

It never marks anything as spam, no matter if I send it to the spam folder. It tells me there is lots of ham, but no spam.

Run the "Filters->Rebuild Bayesian Word Lists" command and see if the wdb files are bigger than that. They should be larger than 1 kb.

Then once you've done that it should start to work if it's in live mode.

If you receive a spam after that then click "Filters->Analyse selected mail" and see if some of the words have a value near 1 (e.g. 0.8967), that means it's a spammy word. If the overall value down the bottom is like 0.7 then the bayesian filter is working but the mail didn't go over the threshold needed to mark it as spam (which is 0.9).

Rebuilt and my filesizes are:

hamwords.wdb 447kb
spamwords.wdb 1kb
whitelist.wdg 21.kb

I have 269 messages in my spam folder, none of which ever get analyzed.

Any ideas?

Thats weird. Which version are you running?

I'll have to get you to run a debug build. I havn't set that up yet.

Just to add my observation:
I had let about 120 spams (that I moved myself) build up in the spam folder while basian was set to learning.
After I got a decent amount built up I switched to live. I had to rebuild the word list to get any wdb files at all. But only after I read this post did I know to do that.
Hopefully it will start identifying spam now.

Hi fret, any word on a debug build? It still doesn't work for me. Thanks.

Just sent a build to you.
12/09/2005 12:13pm
To what address?

Your gmail address that you've used here on the forums... themaskedman [at ] gmail [dot] com

Oh, I see. It didn't make it through then. It's not in my Inbox or junk mail. You might try sending it to Thanks :)

Ok I've sent something to that address as well.
