   Actually running something the size of Yahoo, it would be much easier to
create their own whitelist.    A server that consistently sends content not
scanned as virus or spam, and not voted as spam by users would earn respect
points.     This would withstand short periods of spam, then would be
removed from the whitelist.   If the spam is auto- or manually- damped, the
server would make its way back to the whitelist.

  The whitelist would be much smaller than the blacklist.   Yahoo is
probably trying to treat domain keys as a pseudo whitelist, but that's
stupid.   Spammers are now the primary users of domainkeys.   Even some
spambots can generate domainkeys.
