Actually, my analysis of spam seems to indicate authentication of remote
SMTP servers through a process similar to joining this list would remove
99+% of SPAM.  i.e. the first email from a particular remote server that
is received, requires the sender to take some action (respond with a
password, click on a URL, etc.) before the mail gets through.  One of
these days I hope to write the procmail rules to do it (if I don't find
someone that has done it already)
