All but 33 were classified as junk, i.e., 85 were classifed as junk. I downloaded the same 118 messages with the Thunderbird email progam and all but 100 were classifed as junk, i.e, 18 were classified as junk. Though I like Thunderbird, unless I can get the junk mail filter to work better, I will not be able to use it. Note I transferred my Mozilla profile when I installed Foxfire Any help or suggestions would be appreciated. Andy Reproducible: Always Steps to Reproduce: 1. Download email 2. Allow enabled junk mail controls to work 3. View result and see that most junk emails not classifed as junk Actual Results: View result and see that most junk emails not classifed as junk Expected Results: Junk emails should be classifed as junk at least as well as done by the Mozilla 1.7.x email program.

It's exactly the same junk mail filter. The difference is due to the training data : you have to indicate which messsages are missed, or which mail shouldn't be considered as junk. That will improve the filter. I think it's possible to migrate the traning data from Mozilla to Thunderbird : look for a file called training.dat in your profile folder.

I just looked for the training.dat files in Mozilla and Thunderbird profiles. The Mozilla file is 5799kb. The Thunderbird file is already 6254 kb. Yet I get drastically different results as outlined above

Yet I get > drastically different results as outlined above Were those training-data files generated with the same data ? A bigger data-file doesn't necessarily mean a better filter either. All depends on the traning data *and* the junk mail itself. Anyway, the engine is still the same. One of the recent changes was a better initial training.dat file to help new users, that's all. BTW: what was the Mozilla version that you aspeak off ?
Summary: Thuynderbird junk mail filter not as good as Mozilla 1.7.x junk mail filter → Thunderbird junk mail filter not as good as Mozilla 1.7.x junk mail filter

I'm experiencing this same bug. I used to use Mozilla Mail 1.7.3, and the junk filter functined with very high efficiency in this version (and on all previous versions I used). Ever since I moved to Thunderbird 1.0.2, the junk filter has been significantly less efficient at classifying junk mail -- very large numbers of false negatives (no false positives). I haved saved all of my junk mail since 2003 so that I can retrain the filter whenever I need to, so I have a very large body of junk and non-junk mail on which the filter has been trained. I completely uninstalled and deleted all configuration files (including training.dat) for Mozilla 1.7.3 before installing Thunderbird 1.0.2, so I don't think it should be a conversion problem. I had Thunderbird produce a completely fresh training.dat file using my existing large collection of junk mail and non-junk mail -- the same collection on which I trained Mozilla Mail. Thunderbird's filter is definitely not functioning as well for me as Mozilla Mail's though using the same body of junk and non-junk for training.
Just an update on my experience: I'm currently using Thunderbird 1.0.6, and I have to say that the junk mail filtering seems to be working just as well as I remember in Mozilla 1.7.3. I'm not really sure what changed, if anything, other than the content of the spam I've been getting, but I really have no complaints about Thunderbird's junk filter any more. As far as I'm concerned, this bug has either disappeared, or perhaps it never really existed for me to begin with and my mind was playing tricks on me.

The junk mail filter in 1.06 only filters about 65% of junk mail, i.e, I get a 100 messages 66 labled as junk. However about 35 of the remainder are junk. Filter is not as good as early version of Mozilla.

Do you have an update for this issue, with a later Thunderbird? e.g. 1.0.7 See also my comments on related issue (bug 268101)

This should be better now in TB 1.5 and 2.0 and reporter appears to be gone, closing incomplete. That is not to say junk processing does not have its problems, sof you see a problem in 2.0 please check one of the existing bugs. ref: http://kb.mozillazine.org/Junk_Mail_Controls
