-----------------------------+--------------------
Django appears to insert message/rfc822 attachments in base64 encoding.
This breaks display in Novell Evolution
[https://bugzilla.gnome.org/show_bug.cgi?id=651197 #651197] and Mozilla
Thunderbird [https://bugzilla.mozilla.org/show_bug.cgi?id=333880 #333880].
This behaviour is similar to some other mail clients (namely Gmail and
Microsoft Outlook), but is non-standard according to
[http://www.ietf.org/rfc/rfc2046.txt RFC2046]:
5.2.1. RFC822 Subtype
No encoding other than "7bit", "8bit", or "binary" is permitted for the
body of a "message/rfc822" entity.
The Mozilla Thunderbird bug entry seems to indicate that with certain
versions of Thunderbird, this behaviour is accepted, but this seems to
change sporadically. They believe that encoding message/rfc822
attachments in this fashion is not acceptable behaviour.
