Anyone remember MacTCP 2.0.4 (or maybe it was 2.0.6)? Its resolver library
(not derived from BIND, AFAIK) rejected names that didn't conform to the
RFC, so suddenly lots of Macintosh users couldn't connect to hosts with
Apple probably thought they were applying the "be conservative in what you
send" half of the Interoperability Principle, by not sending DNS queries
that contained invalid hostnames. But actually they were violating the "be
liberal in what you accept" part, since the user supplying the name is not
generally the source of the data, the remote domain administrator is. But
those domain administrators are clearly violating the Principle.
