No -- unless you ultimately trust the RBL to produce a *negligible*
amount of FPs. Every single RBL does have FPs to a highly variable
degree. Instead ob outright blocking on a hit, it is a good idea to
assign a score for the hit only, and see what the result is after all
tests have been performed...

Exactly the SA approach. A single (or even a few) rules and RBLs can
misfire, without affecting the overall deliverability of a particular
mail.

As mentioned a few times already -- do train Bayes instead. That's a
mis-fire of Bayes, and needs to be corrected.
