Re: [dspam-users] DSPAM Groups / global User

hi

we used dspam_train for training. spam mails were collected in some random catchall account which had several thousands of emails.

we also did the same
[root@ns1 ~]# /usr/local/dspam/bin/dspam_stats -H globaluser
globaluser:
TP True Positives: 13417
TN True Negatives: 5478
FP False Positives: 27
FN False Negatives: 571
SC Spam Corpusfed: 619
NC Nonspam Corpusfed: 0
TL Training Left: 0
SHR Spam Hit Rate 95.92%
HSR Ham Strike Rate: 0.49%
OCA Overall Accuracy: 96.93%

we use classfication method ie
globalgroup:classification:*globaluser where globaluser is trained with the spam and ham emails

but there are some bugs related to this which we are already discussing in the forum with subject Re: [dspam-users] DSPAM - tagging question

also please see this
http://dspam.nuclearelephant.com/dspam-users/5413.html

using merged groups -- well i have not used that yet. But please post your results online.

we are planning to create a good readme file for dspam based on people's experiences, primarily so that hundreds of man-hours are not wasted in "re-inventing the wheel" in just trying to understand the current Readme.txt rather than understanding DSPAM. Your results will be useful for this

also one other post mr. tonni is using shared groups successfully so all of this will add up to the common good
