Rather than viewing control of a domain as indicative of good email 
behavior, positive reputations based upon histories of DKIM signatures 
could offer an alternative or enhancement to methods currently used in 
the disposition of messages.

As SMTP transitions into the use of IPv6, IP address reputations will 
also need to rapidly transition to a positive mode of assessment as 
perhaps the only method that has a chance to scale in the face of new 
levels of abuse.

It might be interesting to review information exchanged during DKIM 
assessment, such as a hash of the i= value in conjunction with the DKIM 
key location.  Perhaps a new industry standard could be adopted in this 
regard.  It might be interesting to find whether there might be interest 
in developing third-party authorization schemes.
