... but stream_by_recipient will cause you to send bounces instead
of rejecting the email, if the spam was sent to more than one recipient.

You cannot have per-user configurations, and reject spam based on 
spamassassin score, in a general way, because of limitations of the 
SMTP protocol. There is little that mimedefang can do about that.

I am trying to do the same thing though :) but I don't think per-user
scoring with the granularity that spamassassin offers, is scalable.
I'm aiming for a few classes of SA settings, and probably also dividing
remote hosts in spammishness-levels, and then selectively tempfailing
multiple recipients when you receive different "classed" users from
spammish remote hosts. But that's currently only in the "idea" stage...
