Hmmm.  At the moment, it sure looks that way.  Happily (at the moment)
those methods do a very good job: roughly 85% of total spam rejected
is rejected by those means before any IPv4 methods are used.  But I
have to guess that this percentage will decline and that I'm going to
need to revisit/revise this.
