I noticed that when I call Mutt with the stdin set to /dev/null, Mutt sends the message without asking for confirmation, e.g.,
mutt 'mailto:m...@mail.zz?subject=test&body=hello' </dev/null I find this to be an issue since some programs (e.g., Mathematica) use xdg-open to send automatic feedback with the stdin set to /dev/null. If Mutt is configured to handle the x-scheme-handler/mailto mimetype, then this results in messages being sent without the user being aware of it. Is there any way to disable this behavior? -Rahul
