I liked that idea, but I checked with my hosting company and
SpamAssassin is run on a different machine so that variable isn't
available to my filter.

OK, so a number in an Exim filter is necessarily an integer. (I
suspected this but wasn't sure.)

As it turns out, I've noticed that messages with a positive spam score
have another with a string of int(score) plus-signs:

X-Blackcat-Spam-Score: 5.9
X-Blackcat-Spam-Level: +++++

So if I want to write a condition equivalent to "score >= 4" I can say

$h_X-Blackcat-Spam-Level begins "++++"

and that will match
X-Blackcat-Spam-Level: ++++
and
X-Blackcat-Spam-Level: +++++
but not
X-Blackcat-Spam-Level: +++

right?
