Discardable/Exclusive



My original observation was that "discardable" was a 
reasonable term for mail for which the sender prefer the 
recipient not deliver a small fraction of legitimate email and 
a small fraction of non-legitimate email rather than deliver either.


Let's set aside your preference for a small fraction of all mail rather
than my preference to examine a larger percentage of a smaller subset
with regard to DKIM signing.

Flip the question around regardless of which view one chooses to take.
The question is really:

If a domain chooses to sign DKIM with respect to a From field email
address that purports to be from that domain and that domain has the
ability to make an assertion (of any sort) through SSP with regard to
it's practices:

Is the potential benefit afforded a receiver by checking that SSP
assertion AND taking whatever (unspecified) action worth the effort of
doing so? If receivers are likely to have little or no benefit/interest
in checking SSP then the rest of the discussion is moot.

In other words, is the juice worth the squeeze?

Mike
