Is it prudent for domainkeys to attempt making assurances for the local-
part of the mailbox address? Not accommodating this local-part assurance
(via individual keys), would acknowledge domainkey's relative weakness in
terms of its ability to scale in this manner.
this is a transit validation mechanism, not a full-fledged legal signature
mechanism.
the nature of the 'assurances' being offered are intentionally minimal. the
purpose of the finer-grained keys has more to do with management than it does
with making strong assurances about the purported author.
