Hello, The GPG defaults are not secure for privacy. TorBirdy fixes this in ThunderBird/Engimail via using the "GPG commannd line arguments" override. See here for example: https://github.com/ioerror/torbirdy/blob/master/gpg.conf If users were allowed to insert GPG command line arguments it could fix the problem, or consider importing these as an option in the GPG preferences. Thank you.
What stops you from configuring your gpg.conf the way you want?
