I REALLY do not want an SSP that says "I sign everything, and here is 
my estimate on a 0 to 10 scale of how much you should care."
Is that because you can't trust the value, or because it opens up an
avenue for a spammer who'll get through if he keeps trying, or
because of something else? (Just wondering.)
I don't know what a Care Value of 6 means, and I don't think anyone else 
does either.  And I'm quite confident that whatever my CV 6 means, it's 
not the the same thing as what your CV 6 means.
It may sound like I'm channelling Dave here, but I don't want to put 
anything into a protocol that doesn't have a straightforward operational 
value, and I don't think that "stir it into the mix in spamassassin" is 
straightforward.
R's,
John
