Resurrecting an old topic, Email Address Internationalization (EAI).
The original message is at

It doesn't mention RFC 6531, SMTP Extension for Internationalized
Email, which is what this message is mostly about.

- SMTPUTF8 looks relatively straightforward to implement, at least.

I've done that on a branch, smtputf8.  I'd like to include it in 1.7.

One design issue is how should the user enable sending of 8-bit
(UTF-8 encoded) addresses.  My first attempt was two explicit steps,
one to disable RFC 2047 encoding of addresses in the draft message
and the other to instruct post, via send, to use SMTPUTF8, if
supported by the SMTP server.  In terms of What now? responses:

   What now? mime -headerencoding utf-8
   What now? send -eai

But to make it more convenient and remove potential mismatches, that
-eai switch in the second step could be removed, so it would just be
send as usual.  post would look at the draft and automatically use
SMTPUTF8 if it has any 8-bit header field bodies.

Whatever we come up with, I will need a setting for 'default utf'
to handle my little corner of the world.  I don't want to type send -eai
for practically every piece of mail I create or reply to. :)
