I myself have only plain old 7-bit ASCII domain names, and will only have such, for the indefinite forseeable future. Other people however have been known to send e-mail, on occasion to my server(s). Those other people have other domain names. In the current era, some of those domain names may perhaps be "internationalized". Postfix may... and indeed generally will... put those domain names into Postfix-generated mail headers, for example Received: headers, Return-Path: headers, and possibly others. It will also pass those domain names to external policy servers. In all these cases, I would like to know if Postfix will represent the domain names in question as either (a) Punycode or else (b) Unicode.
