How much spam (esp chinese) have you trained it with?
Below is the stats:
dspam_stats -H [EMAIL PROTECTED]
[EMAIL PROTECTED]:
TP True Positives: 648
TN True Negatives: 290
FP False Positives: 0
FN False Negatives: 202
SC Spam Corpusfed: 89
NC Nonspam Corpusfed: 1359
TL Training Left: 851
SHR Spam Hit Rate 76.24%
HSR Ham Strike Rate: 0.00%
OCA Overall Accuracy: 82.28%
Among those false negatives, at least 50% are Chinese. So, at least 100
Chinese spam have been fed to dspam as errors.
