I'm reading the archives on ADSP and haven't seen anyone pitch the idea that on verification failure, we could have the message in question would be BCC'd to the domain owner's administrator for review.
That way there is no need to rely on 3rd party ADSP reliability lists, and in the event the domain owner doesn't understand the implications of a ADSP record, they will quickly be informed of the matter (perhaps with a full inbox). If this is a new, and welcome idea, there are many things to discuss such as the audit message format (does it look like an NDR addressed to some email address), can the ADSP audit email address point to a separate domain, and if it is desirable to prevent older verifiers (that are unable to BCC an audit message) from reading the new, vetted, ADSP policy. And while we're at it.. why not add this ability to SPF/SenderID as well?
