whitelisted, so no tests were performed and there are no results to
pass on. There is no benefit in over-optimizing this code path, if
DNSbl lookups were performed, the data is cached in your DNS cache,
and another lookup will be quite cheap.
As for policy daemons, they may run before or after Postfix performs
any RBL lookups, and the complexity of trying to pass such data to
them is not worth the effort.
