This is probably what everyone but Carl Worth wants. :-) If the "--all" command works for you, even better, but I doubt it as it would store all your mails in RAM. I'll need to work on some chunking for this. 1b) start out with nnotmuchsync -s if your notmuch tags are authoritative and it will modify your Maildir flags accordingly. After that a periodic: 2) "notmuchsync -s" syncs tags to flags (Currently 'S' only) 3) "notmuchsync -p" purges mail files with "delete" flags
