It's true that problems like replying from ASCII user to EAI user will create chaos (no delivery for sure). Also, it's true that replying to alias - different address who sent initial email, is tricky and chaotic for mailing software (and users as well). And I also agree there's more issues (sorting and searching through a backup of emails, admin features - banning both email addresses etc).

Anyway, thanks for chatting, at least we clarify some ideas, and we saw why we can't have EAI ready mailing software yet.

And I still think "xn--..." would be better solution for user (mailbox) name in RFC, instead of SMTPUTF8, BUT we have what we have...

It may well probe the remote systems to see if they announce SMTPUTF8, but
that does nothing to solve the other problems.  Really, all it does is to
persuade people that EAI is more trouble than it's worth.

R's,
