I somehow agree with David here, and have tried to configure 
Spamassassin and sendmail-milter accordingly, with no success.

I'd like SA to block everything with a score higher than N
(550 Blocked By Spamassassin) - This is easy.

I do not want mail that SA has classified as almost certainly not spam 
to be greylisted.
But then I'd like to greylist everything that is not blocked, but that 
is still suspicius (I.E. a score lower than N, but higher than M).

But I geuss this is best solved by talking to the developers of one of 
the greylist-milters, to make them add a feature to whitelist email 
based on a custom header. (For instance "X-Spam-Level: ***")


Rgds.
