We would like to provide a self-service restore function to our users using their IMAP client of choice..
Our idea was to use a snapshot (under ZFS, btrfs, whatever) and have it available to the user in a namespace. Unfortunately, but understandably, dovecot doesn't like the mdbox structure to be read-only. Is there any chance to change that? In the meantime, we could use a read-write snapshot, but we wouldn't like the users to really do changes to that snapshot. Our next attempt is to use ACLs, but it's a bit hard to gt the ACLs to the correct place in the snapshots, at least for thousands of users. Our currents solution (in test) is a quick and dirty patch to introduce inheritance to the ACLs by walking up the directory tree, so we need only one ACL. A cleaner solution would be very much appreciated. Yours Jost Krieger -- | Helft Spam ausrotten!
