[Evolution] mail i18n issues

[Dan Winship <danw helixcode com>]

Are there any standards/proposals/theories on the internationalization
of strings like

        In-Reply-To: Your message of DATE <MSGID>

        On DATE, PERSON wrote:

        This is a multipart message in MIME format.

?

I am aware of the Content-Language header, but that's useless because
no one uses it.

Failing a good solution, do people think it is better to write pretty
text in English or write ugly language-neutral text. (Eg,
"In-Reply-To: <MSGID>", and skip the other two entirely.)

Is it common for mailers in other countries to translate the English
message header names to local forms for display?
