Hello Stevan,
Thanks for the tip. Actually i did everything with a PHP script, but it
works more or less in the same way;
dspam is working in "opt-out" mode, but it's ok to use optin and the
preferences.

Ok,
So it's better to use a -o content_filter=lmtp:unix:path/to/dspam.sock
in the smtp service?

Thanks, i've followed here and there some (old) howto-s, actually that
spam&ham is really old.

It's just strange, in posted logs i've seen the "user was associated to
group xxx" but i'm not seeing anything like that.
My goal is to accelerate accuracy, all users use the same language and
more or less the same type of mails, so i was thinking about a "global"
group pre-trained with corpus, and re-train it with user's spam&ham that
they put in their folders.
I know, dspam is absolutely not spamassassin: but i'm trying to
accomplish the same things - users are not power users and they just
don't want spam ( .. who wants?) just "out of the box"
