True, and there will always be an arms race between spammers and
those of us who run servers to try to protect ourselves from unwanted junk.
But certain approaches are still quite effective and we should still
be utilizing them when appropriate. Hopefully, the good guys will be
able to keep ahead of the technology curve to put the screw to the bad guys.
