It is essential to a particular class of spam, as I mentioned in my
previous message.
There are a lot of tools that only stop spam on an incidental basis, but
are really only useful because of that incidental benefit. Think RFC2821
syntax checks, greylisting, callback systems, etc., all of which are
designed to probe implementation weaknesses instead of "block spam", but
which happen to achieve that goal anyway. MARID would be the similar.
