Does this configuration make it possible to use mutt's "e" command and write edits back out to the inbox ?

I ask because I had tried it myself some months ago and I found that although my editor (emacs) wrote out my edits to local temp storage successfully, my edits did not make it back to the message on the Protonmail server - the message in the inbox remained unchanged.

I apologize if this comment does not belong here.
