Set your RBL(s) to /reject rather than /warn. Then use
recipients_reject_except to do a lookup in whatever form you'd like for
the addresses that opt out of it. I'd also recommend keeping your
support/postmaster/etc addresses in that list as well.
By the way, the MAPS RSS and DUL catch far more than the RBL itself. I'd
highly recommend using those in addition to the RBL.
