I am imperfectly signing messages with DKIM that I am sending via my home
machine on a dhcp address purported to be from bill.oxley.home.com a vanity non
existent domain. According to DKIM that message is to be treated as unsigned,
why do you wish to drop it?
Thanks,
Bill Oxley

A compromise proposal has been laid out which is to remove the NXDOMAIN
step from the algorithm but add text defining ADSP as applicable only to
domains which actually exist in DNS. This removes the need for ADSP to
specify how (or by what means) such a check is determined, does not
introduce normative language, addresses all the objections yet put
forth, and still provides a basis for believing that a check will be
done.
But I want more than a "belief" that a check will be done. It must be made
abundantly clear that a check MUST be done. I do not mind if the exact
details of the check are left open, just so long as verifiers NEVER let
through a message with an Author Domain that does not exist.
