Notice that the default file name to save the message has ".mbox" suffix
while freedesktop mime database entry assumes ".eml" for the
"message/rfc822" mime type:
As a result if "message/rfc822" mime type is associated with
thunderbird.desktop file then the application starts composition of a
new message with the .mbox file as attachment instead of displaying the
I have not managed to convince thunderbird developers that there should
be a way to tell the application that some file should be opened namely
as a message no matter what is the name and the extension of the file.
They believe that current heuristics is correct and ".mbox" suffix means
collection of messages in "application/mbox" mail box. Thunderbird does
not support opening a mbox file outside of its mail directories.
While I am still thinking that such behavior is partially a thunderbird
fault, I suppose, debbugs should follow conventions and use .mbox file
suffix only for downloading of the whole discussion.
Single message should be saved to an .eml file.
