Read all about it: https://datatracker.ietf.org/doc/draft-levine-appsarea-eaiauth/
This is an updated version of a draft I wrote two years ago, that tries to nail down the small changes to SPF, DKIM, and DMARC in EAI messages. This version adds a section for the Authentication-Results header.
What it mostly says is that wherever you can have a domain name in a mail message header it can be a U-label, and wherever there's a mailbox, the local part can be UTF-8, while stuff in the DNS doesn't change and domains there are A-labels, same as always. It's intended to be utterly unsurprising, but there's enough ambiguity and well-intended bad advice in existing RFCs that I think this is worth doing.
I'm working on an intro to implenting EAI document underwritten by ICANN so it would be nice if this were far enough along that I could point to it in the relevant sections rather than just Making Stuff Up.
