You can see from this line that it needs to receive another 143 messages before it is out of training. It requires about 2500 messages before it flips a switch. I can't remember what switch but it flips one. When I setup myself years ago, I found a corpus of spam, and I fed it my entire mailbox + the spam. Now you can see my stats years later: TP True Positives: 3354 TN True Negatives: 239849 FP False Positives: 1448 FN False Negatives: 981 SC Spam Corpusfed: 0 NC Nonspam Corpusfed: 0 TL Training Left: 0 SHR Spam Hit Rate 77.37% HSR Ham Strike Rate: 0.60% PPV Positive predictive value: 69.85% OCA Overall Accuracy: 99.01% You don't have enought data for dpsam do reliably do anything. Retraining one message as spam will *not* automatically get it to be classified as spam on the *next* classification. Watch the numbers in your stats which says whether training is occuring. If you have a false negative (ham as spam), train it and you should see the FN increment. If it does dspam is working as expected. The other implied part of your question is 'Why isn't dspam effective yet?'. Which is partly due to the amount of mail you've received so far, the type of spam, and the dspam settings. I used to setup people with TEFT as those were the recommendations and I think the default. Over the years I've seen it mentioned on this list multiple times that you should use TOE by default. I also use Algorithm graham burton Tokeninzer osb because of users of this list back in the day explaining that they were better defaults. ------------------------------------------------------------------------------ _______________________________________________ Dspam-user mailing list Dspam-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dspam-user
