Is there a straightforward way to disallow the deletion of all IMAP mailboxes?
I have a user who's deleted an important IMAP mailbox and I'm now recovering a recent copy from the backup. But I'd rather just blanket disallow all folder deletions.
The user is using Thunderbird and this has happened more than once so I suspect Tbird is willing to let a folder get deleted too easily. Perhaps there was a delay in the confirmation dialog and the user clicked ahead and confirmed something he shouldn't have.
I'm looking at http://wiki.dovecot.org/ACL and it looks like I should be able to use a group override to disallow "x" (mailbox delete) but the page says that groups aren't implemented, so I don't know how one says that nobody can do this for any mailbox.
Using global ACLs gets you closer at least. You can define:
acl = vfile:/etc/dovecot/acls
Then having /etc/dovecot/acls/.DEFAULT probably does something.. But I don't remember if it applies to all mailboxes or just those on the root level or what. I should look into this some day and make all of them possible. :) This actually may have a real benefit to some specialty folders - such as junk/nojunk folders that are looked for by a scanning re-classifier.
Can you give an example of how to make...Inbox/Junk non-deletable (or even better, update the wiki)?
