Read all about it:

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
adds a section for the Authentication-Results header.

What it mostly says is that wherever you can have a domain name in a
message header it can be a U-label, and wherever there's a mailbox, the
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
relevant sections rather than just Making Stuff Up.


SPF can use mailfrom local parts, so that needs to be addressed in addition to 
what's in the draft.  I know it's not commonly used, but it is used and is part 
of the standard.
