Need advice on groups. My users do not teach their dspam. I have to
repeat this again, my users do not teach their dspam.
Currently I am using my account as GLOBAL GROUPS. Here is my group
setting in /home/dspam/group
groupGlobal:classification:*myacco...@example.com.sg
I train my account whenever there is an error. I am using TOE. Here is
my dspam_stats.
myacco...@example.com.sg:
TP True Positives: 18152
TN True Negatives: 59943
FP False Positives: 233
FN False Negatives: 1216
SC Spam Corpusfed: 0
NC Nonspam Corpusfed: 0
TL Training Left: 0
SHR Spam Hit Rate 93.72%
HSR Ham Strike Rate: 0.39%
PPV Positive predictive value: 98.73%
OCA Overall Accuracy: 98.18%
Is this the best type of group to use when my users do not train their
dspam? Or should I use merged group? The sad part is my users do not
train dspam.
Advice is appreciated.
