Lets discuss in detail  when we are there in HK/China.

However, What if someone create local part email ID which starts with xn--@idn , where xn-- is not punycode just a ascii string, obviously ACE conversion will FAIL, that was the primary reason that punycode in local is not recommended.

Thanks.

punycode@punycode is certainly allowed, but the "punycode" in the local
part is an ASCII local part that starts xn--..., not coded UTF-8.

By the way, if people use this very much I expect you`ll find that sites
start to block you, because the address tests it`s doing look just like
the tests that spammers do to try to wash spamtraps out of their purchased
lists.

Moral: spammers ruin things for everyone.
