[EAI] New version of E-mail Authentication for Internationalized Mail draft

["John R Levine" <[e-mail]>]

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.

R's,
John
