Package: thunderbird
Version: 1:91.7.0-2
Severity: minor
Since thunderbird-87 it is possible to open particular messages from
command line through their Message-ID's:
thunderbird 'mid:23bc2bd1b0affd193daf52c8f4372...@smtp.spaceroots.org'
See e.g. https://bugzilla.mozilla.org/264270 The "mid:" URI scheme is
defined in https://www.rfc-editor.org/rfc/rfc2392.html "Content-ID and
Message-ID Uniform Resource Locators"
However to open links from other application, "mid:" scheme should be
advertised in the thunderbird.desktop file:
MimeType=message/rfc822;x-scheme-handler/mailto;x-scheme-handler/mid;text/calendar;text/x-vcard;
instead of
MimeType=message/rfc822;x-scheme-handler/mailto;text/calendar;text/x-vcard;
Please, adjust this field in the desktop file. To check that the change
has effect the following command may be used:
xdg-open 'mid:23bc2bd1b0affd193daf52c8f4372...@smtp.spaceroots.org'
Notice that it is not an upstream issue. Thunderbird developers left
desktop integration up to maintainers of Linux distributions. E.g. in
Ubuntu the thunderbird.desktop" file has been updated already for the
upcoming release, see https://bugs.launchpad.net/bugs/1960614
Long time ago it was possible to create similar links to particular
messages using thunderlink extension but migration from XUL to
WebExtension add-ons broke it. Support of the "mid:" scheme restores
linking of mail messages from other applications.
Workaround: add to the ~/.config/mimeapps.list file
