You must have missed my previous messages pointing out how trivial it is
to adjust spam to work around LMAP.  As I've noted elsewhere, if blocking
a particular flavor of spam were all we needed to do, we would have solved
the problem when the RBL blocked Cyber Promotions, or dialup ISPs blocked
outgoing port 25.  A scheme that only works if spammers don't change isn't
of much use.

No, I want a method that protects against a significant amount of spam at
least a little bit, in some way.  LMAP fails that test completely.

We have plenty of evidence against spammers.  LMAP would be only a very
minor help in building legal cases.
