Question 1: Am I correct in that if I want to provide the
"Subject" header in more than one language, I have to use
the Message/rfc822 content-type for each of the language
alternatives.
Question 2: If yes to question 1, should the "Message-ID",
"From", "To" and other headers be repeated in each rfc822
body part (as I have done below for the English version,
but not for the German and French version)?
Question 3: If yes to question 2, should the "Message-ID"
be different for each translation and different from
the Message-ID of the multipart/alternative?
