[imp] unnamed text/html or unnamed text/plain

[Ziaur Rahman]

Thanks for the in-depth explanation. Just an idea: right now the alternative
parts are scattered all over the message body. This make the message body
ugly.
Is it a good idea to have a link right on top or bottom of the message body
like "Alternative Parts" and this link will provide a page where all the
Alternative Parts will be listed?

Regards,

Zia

|| No, doing so violates the RFC.

|Actually, that is not entirely correct.  From RFC 2046 [5.1.4]:
|
|   It may be the case that some user agents, if they can recognize more
|   than one of the formats, will prefer to offer the user the choice of
|   which format to view.  This makes sense, for example, if a message
|   includes both a nicely- formatted image version and an easily-edited
|   text version.  **What is most critical, however, is that the user not
|   automatically be shown multiple versions of the same data.**  Either
|   the user should be shown the last recognized version or should be
|   given the choice.
|
|Thus, to be RFC compliant, all the mail user agent (e.g. IMP) needs to do
|is show the _last_ alternative part that can be displayed.  The
|language in
|RFC 2046 does not require the mail user agent to show all of the internal
|alternative parts.  We happen to combine the functionality identified in
|the last sentence of the excerpt (we show the last recognized version AND
|give the user a choice).  But we NEVER automatically show more than a
|single version of the same data so we are RFC compliant.
|
|That being said, there is currently no way of "turning off" this
|functionality.  However, it should be easy enough to make the necessary
|changes in the alternative MIME_Viewer
|(imp/lib/MIME/Viewer/alternative.php).  I think that showing the
|alternative parts is a good thing (after all, it contains the exact same
|data as the part that is displayed), so I am personally not receptive to
|making this something that can be turned on/off.
