[Dovecot] dovecot-dspam-plugin not launching dspam

[Stefan Schmidt]

i set "mail_debug = yes" in dovecot.conf, restartet dovecot and tried to 
move a mail out of the spamfolder with thunderbird to trigger the 
retraining via the dovecot-module. this of course still didn't work. 
then i checked mail.err, mail.info, mail.warn, mail.log and dspam.debug 
but it didn't write more lines than before in the logs. more ideas ?
