I would actually really like to see this implemented somehow. This is the main reason I asked about ACL a few weeks ago. How does this relate to "shared folders"?From the admin side of perspective, it would be fine, if I could somehow tag folders on server as undeletable. Since binc keeps some administrative files in top dir (bincimap-cache and bincimap-uidvalidity), it cannot be simply achieved by removing write permissions for user and group on the folder, so it would be great if I could create bincimap-undeletable if than Maildir and binc would refuse to delete such folder.
