DSPAM training not working

[Jakob Curdes]

Hello, I have dspam activated on my amavisd and I see dspam scores in the results, so the principal 
dspam setup seems to be working. But I cannot see any training, neither spam nor ham, so the score 
is always -0.100 ...

I use the following integration:

   ['DSPAM', 'Amavis::SpamControl::ExtProg', $dspam,
     [ qw(--stdout --classify --deliver=innocent,spam
          --mode=teft --feature noise ],
         --user), $daemon_user ],
     mail_body_size_limit => 65000, score_factor => 1.0,
   ],

I thought this call would make amavisd train dspam on all messages so that the database should be 
filled up quickly. But the dspam_stats counters remain at zero and so all scores remain the same.

What am I doung wrong?

Regards, Jakob
