Ubuntu configure Postfix mail server encoding to support IDN (internationalized domain names)

ubuntu email encoding postfix virtualmin

Solution 1:

Postfix has SMTPUTF8 enabled by default. See the documentation.

Solution 2:

IDN is handled entirely by the client. No configuration change is needed in server components like Postfix to support it. See for example the Wikipedia article on IDN for an explanation.
