A DKIM base compatible option?
When subdomains or other domains are used to sign the message, a
significant utility is lost. This utility allows the 2822.From
address to be assured on a per message basis independent of a policy
assertion. To overcome this limitation, adopting the r= parameter
could replace the lost ability for asserting the 2822.From is valid
or invalid on a per message basis. When r=1, the signing domain
asserts the 2822.From address has been validated. An r=-1 assertion
indicates the 2822.From should not be assumed validated. The value
of r=0 or not appearing in the signature then defers the 2822.From
validity assertions to the 2822.From policy.
