[neomutt-users] Notmuch folders and Fcc configuration

[Reto]

The easiest solution is to just do it server side, rather than trying to
do it via the MUA.

Your MTA (gmail, $mail_server) should just automatically put the
email into the sent folder whenever you submit to it.

That has the nice added benefit that you *actually* have all mails you
sent in there, even if that's via some dumb iot device that uses your
account via smtp only.

Gmail does so by default, it's relatively easy to do in postfix if you
selfhost as well.

Then your initial tagging script just works™
