Abbreviation: "Realtime Blackhole List". A service that allows
people to blacklist sites for emitting spam, and makes the blacklist available in real
time to electronic-mail transport programs that know how to use
RBL so they can filter out mail from those sites. Drastic (and
controversial) but effective. There is an RBL home page.
