adapt the dspam filter script to learn spamassassin aswell

[mhauser]

currently the dspam filter script is configured to train dspam based on the from address of the user....

this could be adapted to let dspam train for the user "filter" (used by amavisd) AND to train Spamassassin as well.

With this... users could report their spam/ham using the mail addresses (spam@…) aswell.

with this... the dspam filter script would need to be the first content filter in place... forwarding scanned mails to amavis.

Negative point of this setup:
- Virus scanning would take place AFTER dspam has processed the mail

I have to investigate this a little bit more

dspam filter script:
