I'd recommend getting away from the term "rbl" in this context.
The "RBL" is a very specific service operated by the Mail Abuse
Protection System (MAPS LLC), and Paul Vixie rightly gets rather
perturbed when people abuse this term.
You could use the term "dnsbl", in that it is a black list that
is implemented via the DNS.
Also, this implies that you have a per-blacklist method of
controlling what addresses mean what when they are returned by the
map. Right now, what postfix does is if there is anything returned
at all, it assumes that the address that was looked up is on the
blacklist, and it gets blocked. Finer-grained control is needed.
