Yes, almost. You should use new_RE() constructor instead of [],
because what you need to assign to $banned_re_1 should be
a reference to an object of type Amavis::Lookup::RE
(which is a list, but 'coloured'), instead of a plain list.

Right. If there is more than one rules-set in a list, these are traversed
in order (i.e. glued together and given to a lookup subroutine).
