Thanks, this worked for me! Just need to add the ports after 127.0.0.1

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.
