-
-1. Introduction
-
-The "Reply-To" e-mail header is known to be problematic because it is
-used for different purposes by different mailers and when the mailer
-inserting this header and the mailer using the header interpret it in
-different ways, unexpected results can happen. For example, a message
-intended for the author of a previous message only may by mistake be
-sent to a mailing list. One way to reduce this problem is to define a
-new header "Mail-Followup-To" which replaces "Reply-To" in recommending
-recipients for replies destined for the group of people discussing an
-issue.
-
-
-2. The "Mail-Followup-To" Header
-
-2.1 Syntax
-
-"Mail-Followup-To" = "Mail-Followup-To" mailbox-list CRLF
-
-
-2.2 Sender action
-
-The "Mail-Followup-To" header can be inserted by the sender of a
-message to indicate suggestions on where replies, intended for the
-group of people who are discussing the issue of the previous message,
-are to be sent. Here are some ways of constructing this header:
-
-1. Merge the recipients in the "From:", "To:" and "Cc:" headers in
- order to suggest that replies are to be sent to all except "Bcc:"
- recipients of the previous message. Note that omitting any
- "Mail-Followup-To:" header is not the same thing, it does not
- give the protection described in point 4. below.
-
-2. When a message is sent to a mailing list, and the author is a member
- of this list, and wants to get only one copy of replies, the author
- can be omitted from the "Mail-Followup-To" header.
-
-3. When a message is sent to several mailing lists, but the author
- suggests that further discussion should take place only in one of
- them, the names of the other lists can be omitted from the header.
- This is similar to the usage of the "Followup-To" header in Usenet
- News.
-
-4. When a message is sent to a mailing list, which contains sublists,
- there is a risk that the sublists will insert "Reply-To" or
- "Mail-Follow-Up-To" headers referring to the sublist. If this
- happens, replies might be sent to the sublist, and thus not
- reaching the full set of readers of the primary mailing list.
- Use of the "Mail-Followup-To" can be used by the author or the
- primary mailing list to stop sublists inserting "Mail-Followup-To"
- in the header.
-
-2.3 Mailing list action
-
-A mailing list expander may insert the "Mail-Followup-To" header, with
-a reference to the list, if there is no previous "Mail-Followup-To" in
-the message. A mailing list expander SHOULD NOT change an existing
-"Mail-Followup-To" header, since this may reduce the set of recipients
-suggested in the original message.
-
-If a message has a "Followup-To" header, indicating a suggestion for
-further discussion in a newsgroup, a mailing list expander SHOULD NOT
-insert "Mail-Followup-To" except to refer to a mailing list which is
-gatewayed to the newsgroup in the "Followup-To" header. A message
-should not contain both a "Followup-To" referring to a newsgroup and a
-"Mail-Followup-To" referring to a mailing list which is gatewayed to
-and from that newsgroup, so if such a "Mail-Followup-To" is inserted,
-the "Followup-To" SHOULD be removed.
-
-2.4 Mail Client Action
-
-The "Mail-Followup-To" contains a suggestion to the recipient of where
-to send group replies, but the recipient SHOULD be free to choose other
-recipients of a reply. If a mail client contains a command intended to
-write a reply to all recipients of a message, the value of the
-"Mail-Followup-To" SHOULD be used instead of the merge of the "From:",
-"To:" and "Cc:" fields in construction a default suggested set of
-recipients for such a reply.
-
-2.5 Usenet News Client Action
-
-If a message has a "Mail-Followup-To" header, and no "Followup-To"
-header, this is an indication that further discussion should take place
-only in e-mail, not in Usenet News, and thus a Usenet News client
-SHOULD NOT automatically assemble a proposed set of recipients which
-includes any Usenet News newsgroup. Instead, the "Mail-Followup-To"
-header should be used also by the Usenet News client in suggesting a
-default set of reply recipients to its users.
-
-2.6 A note about the "From:" header
-
-Whenever the text above specifies the "From:" header, its value SHOULD
-be replaced by the value of a "Reply-To" header, if there is such a
-header.
-
-2.7 Security Considerations
-
-There are no particular security risks with the "Mail-Followup-To" if
-implemented correctly. Instead, they will reduce the security risk of
-having personal messages inadvertently sent to more recipients than
-intended.

+Appendix B: An Investigation of Handling of
+Multipart/Alternative in some Common Mailers in
+November 2000
+
+
+2 Language Support in Existing Standards
+
+The "Content-Language:" e-mail content header specified in
+RFC 1766 [6] can be used to specify one or a list of
+natural languages used in that message body.
+
+The "Content-Type: Multipart/alternative" defined in MIME
+[4] might be used to send the same text in more than one
+language. Each part would then be marked with the "Content-
+Language:" header to indicate its language, and the
+recipient might choose the body part according to his or
+her language preferences. The combination of
+Multipart/alternative with Content-Language is however not
+commonly supported and gives disastrous results with most
+mailers, so this solution is not recommended in this
+specification.
+
+In HTTP [7], a request operation can indicate a list of
+preferred languages, and the server can then deliver the
+resource in the preferred language. The request operation
+can also indicate how good each language is for a
+particular user, in the format:
+
+ Accept-Content-Language: da, en-gb;q=0.8,
+en;q=0.7
+
+HTTP also has facilities for the server to tell the client
+which alternatives are available in different languages,
+letting the client choose between them. It is also
+possible, with HTTP, to deliver a resource in the
+"Multipart/alternative" format, if the recipient wants to
+store the resource in all available language versions.
+These HTTP features are however not commonly supported
+(November 2000).
+
+All of these methods of transmitting information is based
+on the assumption that all language versions are ready and
+available when a message is sent.
+
+
+3 Multi-Language Scenario
+
+John Smith writes a message in English and submits it to a
+mailing list or to a Usenet newsgroup. The mailing list
+expander sends this message to an automatic translation
+agent which translates it into other languages and returns
+the translations to the mailing list expander. The mailing
+list expander might then either forward all translations to
+each member of the list, or forward to each member only the
+translation preferred by this member. Ernst D’rrenmatt has
+requested the mailing list to send him all language
+versions, but reads this message in English, because he has
+indicated that he prefers English original documents to
+automatic German translations. Hilda Schmidt reads the
+message in both English and German, decides that the
+automatic German translation is not very good, and cleans
+it up, submitting a new better translation to German. Ernst
+D’rrenmatt checks this translation, makes some corrections,
+and submits a final corrected version of the German
+translation of the original message.
+
+
+4 The Content-Translation-Of Header Field
+
+The "Content-Translation-Of" header field is used when
+submitting a translation to a message, which earlier has
+been sent in another language. The syntax for this header
+field is similar to the syntax for the "In-Reply-To"
+header, but only one value is allowed, since every
+translation can only be the translation of one previous
+message. The value contains the Message-ID of the original
+message or of a body part containing the original text
+before translation. If a message is available in
+more than one language, "Content-Translation-Of" should
+always reference the original message, even if the
+translation was actually based on a translated version. If
+the original message is available in more than one version,
+with "Supersedes" or "Replaces" references between the
+versions, then the "Content-Translation-Of" should
+reference the version which was the basis of this
+translation.
+
+Translation is applied to the body content, and to the
+content of the "Subject:" header, but not to any other
+header contents. When a "Subject:" is translated, the
+language code enclosed in parenthesis" can be added to the
+beginning of the "Subject". Example:
+
+Subject: (en) This is the English version
+
+If more than one translation is available of the same
+original message, the "Supersedes" or "Replaces" header
+field should not be used between them. "Supersedes" or
+"Replaces" are only to be used when the original message is
+revised.
+
+
+5 The Content-Translator Header Field
+
+The "Content-Translator" header field indicates who made
+the translation. When a translation is submitted, the
+"From" header field should still indicate the original
+author, but the "Content-Translator" header field should
+indicate who made the translation.
+
+The syntax of the "Content-Translator" header field is:
+
+Content-Translator = "Content-Translator:"
+ ( CFWS mailbox-list / Phrase )
+ *(";" translator-parameter) CFWS
+ CRLF
+
+translator-parameter = art / fluency / future-extension
+
+art = "Human" / "Machine" / "Original"
+
+fluency = "Expert" / "Native" / "Other"
+
+The meaning of these parameters are:
+
+Human = Translation was made or revised/approved by a human
+ translator.
+
+Machine = Translation was entirely automatic, with no human
+ checking of the translation. In this case, the
+ "Auto-Submitted" [8] header should also be added
+ to the message heading.
+
+Original = This is the original before translation. Absence
+ of a "Content-Translator" also indicates that the
+ message is not translated, but
+ "Content-Translator: None;Original" can be
+ used to explicitly specify that this is not
+ translated.
+
+Expert = Translation was made by an expert translator or
+ by an expert in the topic of the message, such as a
+ medical expert for a message on a medical topic.
+
+Native = Translation was made by a native speaker of the
+ target language.
+
+
+Other = Translation was made by someone who is not an
+ expert nor a native speaker of the target language.
+
+
+6 Use of The Multipart/Choices MIME Content Type
+
+When several translations of the same message are sent in
+the same message, the content-type multipart/choices, as
+defined in [9]. An alternative is to use
+mulitpart/alternative in the way described in Appendix A.4
+below.
+
+If translation is desired also of the "Subject" header,
+then the translated body parts have to be of content-type
+Message/rfc822, since only that content-type allows
+different subject in different body parts.
+
+It is recommended to add information about translation at
+the top of each body part (example, see section 8.3 below),
+because some mailers display multiple body parts in
+sequence inline with no indication of the Differences
+between them. This recommendation may be lifted at some
+future time when most mailers have support for
+Multipart/choices.
+
+It is also recommended to add a blank line at the end of
+each translation, since this will show up neater on some
+old mailers, which display all body parts in sequence to
+the recipient.
+
+
+7 The Translation-Request Header
+
+The Translation-Request header is used when sending a
+message for translation to a human or machine translator.
+Its value is a list of the languages to which translation
+is requested. The languages are specified according to [6].
+The language of the original can be included in the
+Translation-Request header, this tells the translator to
+include the original of the message when it is forwarded
+after translation, together with the translations to other
+languages.
+
+When the Translation-Request header is used, the content-
+type should always be "Message/rfc822" [5] and the content
+should be the message to be translated. When the
+translation is ready, the translator is instructed to send
+the translation to the recipients in the "To:", "Cc:" and
+"Bcc:" headers and to leave non-translated headers of the
+message/rfc822 body as they were before the translation.
+When the translator resends the translation, Resent-From"
+is added with the name of the translator, and "Resent-Date"
+with the date of the translation. If translation to
+multiple languages is requested, the result is sent using
+the content-type multipart/choices.
+
+Syntax: "Translation-Request:" CFWS language 1*(, CFWS
+ language) CFWS CRLF

+9 For Further Study
+
+The following is not yet resolved in this draft:
+
+- How a user can register its language preferences with a
+ mail server or a mailing list expander.
+
+- Whether POP/IMAP should be extended with commands to
+ request messages in only a certain language.
+
+- How to handle translation in Usenet News. One might for
+ example have a set of co-ordinated newsgroups, with the
+ same articles in different languages. A newsgroup
+ "alt.cultures.multiple" might be provided with English
+ in "alt.cultures.multiple.en", German in
+ "alt.cultures.multiple.de", etc., with automatic or
+ manual translation of the messages between these
+ newsgroups.
+
+- Handling of signatures and seals.
+
+
+10 Security Considerations
+
+Translations made by other people than the original
+author of a message will of course entail the risk
+of intentional or unintentional incorrectness of
+the translation. But this is a risk we must accept
+if we want to have translations, and if everyone is
+not fluent in every language.
+
+Some people claim that machine translation
+technology is so bad, that it should not be used at
+all. However, machine translation will often give a
+good understanding of the intent of the original
+text even if the translation is not perfect. And if
+the recipient has a choice of either not
+understanding a message at all, or getting a
+machine translation, the recipient may still prefer
+the automatic translation. Based on this, the
+recipient might decide whether the message is of
+enough interest to be willing to pay for a human to
+make a better translation.
+
+The risk can be reduced, if the receiving user
+agent clearly shows that a message is a translator,
+who made the translation, and allows the user to
+check the original text and compare it with the
+translation.
+
+A translation will invalidate any digital
+signatures or seals, but the translator might add
+its own signature and seals to ensure that the
+translation is not corrupted when sent from
+translator to readers. These signatures and seals
+will not promise any correspondence with the
+original text, except the promise which a
+translator might give of the correctness of its
+translations.

+Appendix A: A Discussion of Alternative Ways of Handling
+Translation in E-Mail
+
+
+A.1 Use Multipart/alternative
+
+The most natural solution might be to send a message in
+multiple languages as a multipart/alternative, with each
+body part in a different language.
+
+However, this solution downgrades disastrously bad with
+many existing mail clients, as is shown in Appendix B. Most
+existing mail clients will either show only the first or
+only the last body part in such a multipart/alternative.
+Thus, users will not have the option of getting the message
+in their preferred language, they will instead get the
+message in a language which they might not understand.
+
+
+A.2 Use Multipart/mixed
+
+Another solution would be to use multipart/mixed, and with
+a Content-Disposition file-name containing the language.
+Most mailers will then show the message as a list of
+attachments, listing their file names. The recipients can
+then click on the name of the attachment which contains
+their preferred languages.
+
+The disadvantage with this solution is that it does not
+support future mailers which really do support multiple
+languages and can select the language part according to the
+user's preferences.
+
+
+A.3 Use multipart/choices
+
+A third solution would be to use a new Content-Type
+"multipart/choices". Since the MIME standard says that a
+mailer should handle "multipart/xxx" where "xxx" is an
+unkown subtype, as multipart/mixed. So this solution has
+all the advantages but not the disadvantage of using
+multipart/mixed. If multipart/choices becomes a standard,
+mailers of the future can support it better than
+multipart/mixed.
+
+
+A.4 Use multipart/alternative with additional first
+ and last body part.
+
+A fourth solution would be to send the message as a
+multipart/alternative with the following contents:
+
+First body part: A plain text version of all the
+translations after each other.
+
+Last body part: A HTML version with all the translations
+after each other, and with a list of languages at the top.
+The user seeing this part can just click on one of the
+languages to get this message in that language.
+
+All the other body parts, between the first and the last,
+contains the text in each of the available languages.
+
+The advantage with this is that it will downgrade well with
+existing mailers, they will show either the first or the
+last part, which both contains the text in all the
+languages.
+
+At the same time, a mailer which understands the combinaton
+of multipart/alternative with Content-Language can let the
+user select a language or automatically select language
+based on user preferences.
+
+A third advantage is that no new subtype to Multipart have
+to be defined.
+
+The disadvantage is that the message will be longer, each
+translation is repeated three times, in the first body
+part, in one of the middle body part and in the last body
+part.
+
+
+Appendix B: An Investigation of Handling of
+Multipart/Alternative in some Common Mailers in November
+2000 and November 2001
+
+As a basis for possible work on developing standards for
+language-translation in e-mail, I tested how some common
+mailers handled multipart/alternative with different
+Content-Language in the body parts in November 2000. The
+tests on the Windows Explorer 5.0 were done in November
+2001.
+
+I used the following test messages:
+
+Test message 1: First part English, second part German
+
+Test message 2: Same as test message 1, but first part
+German, second part English
+
+Test message 3: Same as test message 2, but multipart/mixed
+instead of multipart/alternative.
+
+Test message 4: Same as test message 3, but with Content-
+Disposition: Attachment on all but the first body part.
+
+Test message 5: Multipart/mixed on an outer level, with the
+first part a directory of attachments, and the second part
+a multipart/alternative with the German and English parts
+as the two alternatives.
+
+Test message 6: Multipart/alternative with the first part
+containing all the translations in one body part, and the
+second part a multipart/alternative with one translation in
+each alternative.
+
+I tested this with the following mailers:
+Eudora 5 Macintosh, Pine 4.21 on Unix, Netscape 4.7
+Macintosh, Outlook Express 5 Macintosh, First Class 5.611
+Macintosh, KOM 2000 (our own system), and Hotmail.
+
+Result: None of the mailers seemed to test on the Content-
+Language value, and make a selection based on this.
+
+Eudora, Outlook Express, KOM 2000 and Hotmail only showed
+the first body part. Netscape only showed the second body
+part. Pine only showed the second body part, but provided a
+user command to see also the first body part. First Class
+displayed both body parts in sequence, i.e. i treated
+multipart/alternative as identical to multipart/mixed.
+
+The conclusion of this is that if IETF makes a standard,
+specifying that different translations of the same message
+should be sent with multipart/alternative with different
+Content-Language on the different body parts, then most
+mailers will not show a user the version in the preferred
+language of that user.
+
+Since backwards compatibility with existing mailers is very
+important, this seems to indicate that an IETF standard for
+handling of language translation in e-mail has to use some
+other format than multipart/alternative to indicate
+translations.
+
+I also tested some more complex messages. In test message
+4, I used multipart/mixed with three body parts, the first
+a list of the rest of the body parts, which contained the
+message in different languages. This format was not ideal
+either with the existing mailers. Most of them showed all
+three body parts in sequence inline (even though all except
+the first were marked as Content-Disposition: Attachment)
+and some of them without any visible marker between the
+body parts.
+
+In test message 5, on the top level is a multipart/mixed
+with two body parts, the first a list of the body parts,
+the second a multipart/alternative with the different
+language parts. This had the same problem as all the other
+multipart/alternative test examples: Many of the mailers
+arbitrarily chooses one of the multipart/alternatives and
+only shows this, some mailers choose the first alternative,
+some the second.
+
+In test message 6, I had on the top level a
+multipart/alternative where the first body part was a
+text/plain with all the language versions in one text. The
+second body part was another multipart/alternative with the
+different language parts as body parts. A mailer which
+cannot discriminate between languages, should for this
+message only display body part 1. Only Outlook Express and
+KOM 2000 did this. Pine, Netscape and Hotmail arbitrarily
+showed only one language version.
+
+In test message 7, I tested the format proposed in this
+ietf-draft, as shown in section 8.3 above.
+
+Test message 8 uses a first body part with all language
+versions in plain text, a last body part with all language
+versions in HTML, and in-between separate body parts for
+each translation. This seems to work very well with
+existing mailers.
