I added a globaluser and merged group a while back, but the results haven't noticably improved. While dspam seems to work well for some people, it works less for others - regardless of the amount of training each puts in. I'm sticking with it as for the people for whom it works it works very well and hopefully for the others it will at some point also. Better documentation around the groups would be good. I was going to try and write something, but find myself still unsure exactly how the groups work and how best to use them. :-( > > rajesh mahadevan > > > ---------- Original Message ---------------------------------- > From: "Berger Stefan" <[EMAIL PROTECTED]> > Date: Tue, 27 Mar 2007 16:27:18 +0200 > >> Hi all , >> >> I'm new to dspam and i'm a little confused about group settings . >> >> I'm running dspam ( 3.6.8 )in a clustered enviroment with a central >> Mysql >> Server ( write actions ) which is replicating to the local slaves . >> >> Dspam is running in daemon mode and is called via a shell script >>from qmail-ldap .
