Hi everybody,
I'm using DSPAM for about a year and I really can see the improvement of my
SPAM detection infrastructure.
Currently I'm having some complainings about false-positives. Mails from
gmail, other internal (and trusted) domains and mailman lists go straight
through the SPAM box classified by DSPAM.
I started to work with "teft" and then changed to "toe" as instructed by
the documentation. Users complain that they need to train some messages 10
times before dspam recognizes as innocent. Is there a way to improve that?
Is there a way to make dspam classify mail as spam only with user
trainning? The purpose here is to avoid false positives and make the user
to tell DSPAM what is spam.
Thanks.

There is also a list of headers to ignore and I removed mysql connection

Can you help me to improve my system?
Thanks
