I don't understand what you're proposing. Are you saying to look for DMARC
records at the d= domains in the signatures on a message?
Yes, it might be a valid hint in some cases.
What if it has no signatures but might be SPF aligned?
The existence of an SPF record is less indicative, as the protocol suggests
to publish a record for each host. Yet, in case the SPF identifier is a
parent domain, it might be a valid hint too.
I still don't understand. If a message has no DKIM signatures, and the
sender uses SPF alignment, where do you look for _dmarc records? A
concrete example or two would be helpful.
