What is the best way to do this? If there is no such thing currently, would it be hard to implement the sticky bit checking on the root? dovecot-uidlist.lock basically does this. Dovecot comes with maildirlock utility to properly create it. How long would your locks be? They are assumed stale after 2 minutes if you don't update the mtime. Readers will block and if they're still locked after 2 minutes they'll abort (if mtime has been changed). There's also mail_max_lock_timeout setting that changes this wait (you could e.g. lower it only with lmtp).
Well, basically "forever" in the sense that I would like to move the mailbox to a different machine, So you have a proxy that decides what backend server the connections are redirected to? How about you do it completely without locking with dsync? Moving between servers works basically the same as converting a mailbox format, with the difference of "changing mail_location" you "change backend server". http://wiki2.dovecot.org/Tools/Dsync#example_converting
Yes, there is a proxy in front of the servers. Is dsync usable with 3rd party maildir programs? (not only Dovecot uses these mailboxes)
