Hello,

Stephen and I have spent a bit of time working on a draft to be able to show a relationship between two domains.  We're aware this subject has been covered a few times previously, especially in the DBOUND drafts, but we're hopeful that a more simple approach might be more acceptable.   The secondary domain will create a DNS record that shows a link to a primary domain, and the text should be able to be validated using the public key in a DNS record the primary domain shares.  This is something akin to DKIM, a mechanism that the email world uses to ensure the contents of a message have not been tampered with.

https://datatracker.ietf.org/doc/draft-brotman-rdbd/

We'll request that replies relating to this be sent to the dbound@ietf.org due to the nature of the topic, but it was suggested that we might want to notify a few other lists for their awareness.  Thank you for your participation and comments.
