* the local part must not contain special chars * the domain itself does not exist with UTF8 if you look at a nameserver configured vor a IDN domain you will see nothing else than Punnycode, in fact any client translates the userinput to punnycode honestly you have everywhere Punnycode (DNS, webserverconfig as well as mailserverconfig) and nothing else on the low-level side and so postfix will hardly see unicode in the envelope http://en.wikipedia.org/wiki/Punycode
