Well, that essentially translates the score into a description.

The trouble here is that you land up subtracting a constant from
the total score, regardless of the rules that triggered. If a
submitted mail is clasified as spam, but doesn't hit the RBL rules,
it will compensate for the RBL rules score anyway and perhaps pass
the mail.

It turns out that I misread the SpamAssassin documentation and I
can in fact modify system rule scores from a user prefs file. (I've
been spoilt by the quality of exim's documentation.) So all I neede
to do was to setup a virtual config directory for SA with appropriate
scores in a user_prefs file and make the spam condition use a
different user for authenticate mail.

I still think the expanded spamd_servers option is worthwhile and
my boss thinks the current solution is a stop-gap so I might have
some time to do that anyway.
