Re: [Dovecot] Disallow folder delete

[Kenneth Porter]

It might be nice to have a mode that disallows deletion of *non-empty* 
folders. In order for a user to delete the folder, the folder must first be 
emptied and purged.

Alas, deleting messages can be undone, but folders can't be, and the UI of 
a client doesn't necessarily make this obvious.
