The above reference to things happening in transit and some out of
band mechanism sound interesting, but don't have much to do with the
original DKIM work, which really was only about giving receivers a
noise-free basis for evaluating messages associated with an identifier.
Interesting bit from what appears to be the original draft charter,
circulated at the DKIM BOF, November 2005:
The DKIM working group will produce specifications
that permit authentication of message headers during transit,
