How do you handle 'postponed' mail?

Hi, If I create 'postponed' folder inside the notmuch mail database, it takes 'notmuch new' to make mutt notice that there is postponed message. Afaik there's no way of instructing mutt to run a command after postponing message. If I create the 'postponed' folder outside of notmuch mail database, I can't see this folder in the virtual folder list (to remind me that I have a draft there). How (if at all) do you use the postponed feature? Cheers -- Vlad
