hello,

    a little different observation here.

    normally, email address with ascii domain will be regarded as alias of email address with idn domain, or email address with idn domain will be regarded as alias of email address with ascii domain.
both email addresses with ascii domain and idn domain will physically point to the same email box.
in this case, ascii domain and idn domain  should resolve to the same IP address in the DNS after the email system administrators configure the two email address as the alias of each other.

So DNS should do something here.

This is part of the reason several of us find "ASCII domain" and
"[somelanguage] domain" to be such frustrating terms.  There is
nothing -- literally, absolultely nothing -- in the DNS that links
these different domains, and no way to express such a link.  Different
registries will have different policies which link the names
_administratively_, but nothing will link them technically.

So, the way we should properly explain this is, "That's a different
domain, so if you want to get mail there you need to control it too."

Best regards,

A
