Displaying IDN domain names is a client-only issue. Postfix works
with ASCII on-the-wire "xn-<punycode>" names.
Even in bounce messages, where Postfix could arguably process IDN names,
it is far from clear that making bounces only readable by people who can
read Chinese, Arabic, Russian, ... is a good idea. It is best to rely
on MUAs display the structured bounce in the most appropriate way.
