Wouldn't it be the MTA that would be responsible for grabbing fields
out of the header during transmission and adding them to DNS?  This
would require that the MUA or MSA only talk to an MTA that has that
capability for the domains in both the MID and From, which is a whole
different kettle of fish.

It'd be possible for a 3rd-party service to provide both the database
and the DNS for this, but that's essentially re-inventing Goodmail,
which already failed in the attempt.
