Summary0001503: Forwarded mail display problems, sometimes not displayed at all
DescriptionEmacs/Gnus can forward mail with the outer mail Content-Type of message/rfc822 rather than the usual multipart seen in other MUAs when forwarding-as-attachment. This causes a few rendering problems in SOGo:

  * Usually the entire email is shown, including headers, even inner attachment base64 data.
  * Usually inner attachments also show correct download links (in addition to the base64 data).

When I say _usually_, I mean when the attached mail has Content-Type of multipart/mixed.

When the attached email has Content-Type of multipart/signed, the display has the following artifacts:

  * Terse email headers are shown (which is good, but opposite of behavior explained above)
  * The first inner-part is not rendered at all.
  * None of the parts are rendered at all.
  * There is a download link that has some of the characteristics of a normal non-forwarded PGP/MIME application/pgp-signature MIME part (e.g. "Untitled-2 (203)" is the link label), however the link is a broken URL ("/SOGo/so/0" which results in a page saying "object not found: 0")
Additional InformationThis problem was initially brought to my attention when I friend of mine reported that he couldn't see any of the email content of a message I forwarded to him. He also said that the content did appear once he clicked reply.

I have tried several combinations of MUA, attachments, with or without RFC 3156, and forwarding styles, including Outlook and Thunderbird (which do not share the problems described above).
TagsNo tags attached.

Wow you're quick Ludovic ;-)

BTW, one more piece of information regarding PGP/MIME.

Of course I don't expect SOGo to support PGP/MIME, but it's interesting to note that a normal non-forwarded multipart/signed message is rendered correctly. It's only the attachment stuff that seems to break (and if signed message were part of multipart-attached forwarded message, it is rendered fine too)
