Exactly. I have a whole system setup around this because I have a few different mailboxes that I only want to have to maintain in one place (that is, I shouldn't have to update the list of mailboxes in multiple places).

I setup a bash function that gets called as `run_mutt /path/to/RC/file`:

run_mutt()
{
    RC="$1"
    base=$(grep "^set folder=" ${RC} | sed 's/set folder=//g' | sed 's/"//g')
    mapfile -d ' ' -t MAILBOXES < <(grep ^mailboxes ${RC} | sed 's/mailboxes //g' | sed 's/"//g' | sed 's/+//g' | tr -d '\n')
    systemd-run --pty --user --wait --description="Mutt" firejail -- mutt -y -F "${RC}";
    for i in "${MAILBOXES[@]}"
    do
	important="${HOME}/.config/personal/important.$(basename "$i" | sed 's/+//g' | tr '[:upper:]' '[:lower:]')"
	systemd-run --user --wait --description="Update Important (${i})" --unit="update-$(basename "${important}").service" update-important.sh "${base/#\~/$HOME}/${i}/cur/" "${important}"
    done
    systemd-run --user --wait --description="Update notmuch database" --unit="notmuch-new.service" notmuch new
}

base is the base path to all of the maildirs and is set by finding the 'set folder' directive in the RC file (e.g. 'set folder="~/.local/mail"'). MAILBOXES is defined by finding and parsing the 'mailboxes' directive in the RC file (e.g. 'mailboxes "+MB1" "+MB2" "+MB3" "+MB4" "+MB5"'). I have a separate system that lets me flag important emails in Mutt and writes out their subjects etc into files upon exit so that I get those emails in my terminal (that's what the for loop does), but you can ignore that as well as the notmuch stuff (email indexer) if that's not relevant. All of this means that I can set the base folder and mailbox names once in my muttrc and this function picks out everything. Since I only have a few mailboxes (and the list is fairly static), it was easy enough to manually set it in my muttrc.

I believe you can use 'mailboxes = `command`' to set the mailboxes to the output of a shell command if you want as well (so you could write a shell script that automatically outputs the mailboxes in the required format - useful if the list of mailboxes keeps changing).

HTH!
