    This is such a bunch of nonsense. There are millions of people
    who have completely and utterly defeated the spammers while you
    nitwits talk seriously about re-arranging the deck chairs on
    the titanic.

    All of them use a filter that is constructed like so:

    incoming mail
         |
         |
         | 100%
         |
         |
    Pass-List --> mailboxes
         |
         | 5%
         |
         |
         | 95%
         |
    Block-List (broadly-tuned conventional spam filter) --> /dev/null
         |
         | 94.9%
         |
         |
         | .1% (1/10%)
         |
    Challenge-Response --> auto-response

                    .1% (1/10%)
                                 

    AC 

    -- 
Pass-list --> Block-list --> Challenge-Response
