The idea is to have a "golden" list that is so accurate
(for spams it does identify) and has so few FPs that
it would be safe to block outright at the MTA level,
for example.

An MTA milter or plugin probably can't determine that
from multi alone (i.e. looking at all the lists), so I'm
wondering if we can create a list for that purpose out
of the existing lists.

The new list would be just another bit in multi, so it
would still be a single lookup, but it would be looking
up a highly accurate, hopefully zero FP new subset within

SC and JP already come pretty close to that goal, but I'm
wondering if some clever combination of the lists might be
useable to create a single list to outperform the individual
lists.  Obviously any subset will hit less spam, but the goal
would be to make a subset that hits no FPs.

We could probably experiment and try some different approaches
and see how they test out on corpora and live mail servers.
