So SMPTUTF8 clients should be capable to set/choose traditional or internationalized sender address per recipient and split sending of multi-reipient messages? "where there's a will there's a way" I share your opinion that english speaking parts of Internet will be slow to mass support SMTPUTF8. As native speaker of another language I do not see it as a very important obstacle.
