This discussion seems to be about "Should we have an r= tag in
either the signature or key record"

A report vector acquired from the signing-domain would concern
_only_ messages they have signed, and not messages that
happen to contain an email-address within their domain.  For

Are you talking about reporting DKIM signatures that cannot be
verified?  If so, I don't see how you can trust the report vector
acquired from the signing-domain.

IMO, its not as much an issue of trust, it could be a form of attacks, but
so about rather operations.

What are the report limits?  Is the report-domain paying the validator to
send reports, because if not, it could be pretty costly.

I believe there are few implementations in SPF with reporting logic and I
believe it uses some limits in report/notification. If the notification is
not confirmed, then the domain is blocked in future failed transactions.

Similar hindsight will be required for DKIM as well if this r= feature is to
be part of the specs.
