Hi Hanno,

You will need to train DSPAM to let it know what is/isn't spam, if you 
do a search on the list you will find lots of information on the best 
way to do it.
I notice you are using teft as your training mode, again if you read 
the list you will find that it isn't a good system to use any more.


Best Regards
