If I understand you, this means SPF clients will have to traverse a
graph of DNS relationships, enumerate the hosts and domains within N
degrees-of-separation, and build a trust metric for the report argument
based on the results.
This can be done, but is there an easier way to accomplish the same
result? What if DNS/mail providers add a special subdomain
postmaster.customerdomain.com that routes mail to the service provider
instead of the customer?
