I would (using the singular I) ignore any i/d comparisons or usage as a valid
signature represents a
dkim=passed
part of any rules engine. This may be coupled with a subset of adsp requests to
drop non signed or malformed signatures. Otherwise its just one cog in a rule
based asav system.

Subject: Re: [ietf-dkim] dkim usage examples
Not bad questions, but ones that I don't really have answers for. I
could tell you what I *want* out of authentication, but that leads us
to things like *cough* disposition instructions for bad mail and
things like ADSP. Instead of going there, I'd like to learn more about
how what is more or less nearing consensus, and how it is actually
desired to be used by ISPs.

Perhaps it can help to turn this around, and make the technical details be
derivative of functional need.
That is: What kinds of questions and answers would signer and assessor like
to share, which DKIM could help with? What kinds of roles and analyses
would be good to facilitate?

Can you describe particular usage examples you would like to see
explained?
I'm not asking you to give the details, but rather describe what the
details
should explain.
Off the top of my head...
.
Use cases for i= and d=, and what an ISP would care to do with that
data, if they could do anything they wanted to.
What the restrictions are on i= and d= (and other fields/configuration
options I might not be thinking of). What has to match the PRA, if
anything, what can contain a sub-level identifier, etc.
Best,
Al
