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.

Yes Dusan, you will need to own ASCII domain to full ascii Alias ID
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 -- Andrew Sullivan ajs@anvilwalrusden.com
