Hello, I have the case where there is a mail account which receives a lot of spam mails which does not get marked as spam by dspam. The pattern of this mails looks like this: a few random words (3-7) with even sometime words which do not exist or ar written weirdly (v1ägRÄ) followed by a link which always changes URL. It looks like it is somehow impossible for dspam to tag them as spam. Do you have any recommendations or special settings for these kind of mails? or is it simply not possible? Best regards ML |

Hi Steve, Yes I have been training dspam with these messages by moving them into my Spam folder which automatically retrains dspam. I did this more than 100 of these kind of spam mails but without any success.

I am using the teft as TrainingMode. When I retrain dspam with that specific mail by moving it into the Spam folder I can see a new entry being written into the system.log file, here below would be an example: 1385462923 M <None Specified> 4,52946e75120681586112679 <None Specified> 0.121289 my...@my...d Retrained So I can only assume here that the training is working. Or else how can I be 100% sure that the training is working? And here would be the relevant DSPAM headers as taken from one of these spam mails: X-DSPAM-Result: Innocent X-DSPAM-Confidence: 0.6000 X-DSPAM-Improbability: 1 in 151 chance of being spam X-DSPAM-Probability: 0.0010 Let me know if you would need any other details. I would be happy to provide you with these.

I will try switching to TOE. Regarding your other questions we are using OSB as tokenizer yes. Below are the stats for the account I am testing with: TP True Positives: 298 TN True Negatives: 373 FP False Positives: 0 FN False Negatives: 80 SC Spam Corpusfed: 0 NC Nonspam Corpusfed: 0 TL Training Left: 2127 SHR Spam Hit Rate 78.84% HSR Ham Strike Rate: 0.00% PPV Positive predictive value: 100.00% OCA Overall Accuracy: 89.35% btw I would be running this mail server for hosting many domains.
