That would be an option, although I decided it is more useful
to evaluate in all rulesets until a match is found.

This way you have a choice at each ruleset if you want to
terminate the search with a decisive catchall pass or block entry,
or not use a catchall and let the search proceed with next ruleset
belonging to a more general recipient domain key.
