Scott-

Any chance of getting an AND / AND NOT kind of test so we could set up
different weights for an open proxy depending on whether it shows up on a
DUL or DYNA list?

Like this:

OPENPROXY and DYNABLOCK 3
OPENPROXY and not DYNABLOCK 5

I think we might define the tests (with weight zero) in global.cfg and run
this in $default$.junkmail. It would require that $default$.junkmail be
abkle to add weight, though...

I htink this functionality has been requested before, but in a different
context. I cannot recall what that was.
