SSP is a mechanism for enabling domain owners to express their
AIUI, the proposed "checker" will interpret those "expectations" in the
context of the particular message with its particular combination of
signatures, From addresses, Sender addresses and whatever else, and pass
its interpretation on to the "adjudicator". Essentially, the description
of the "checker" in the draft will be just the way of expressing clearly
the "semantics" of SSP.
What the adjudicator then does is out of scope (our scope is to ensure
that he is in no doubt about the domain owner's expectations).
I.e. it is perfectly in order for a standard to speciffy the methods
whereby a horse may be led to water - but no further.
