Will Dovecot ever support renames across namespaces?
I'm attempting to support mailboxes under "INBOX" for compatibility with Courier, which I'm trying to replace, while also supporting mailboxes with no prefix. I don't want to confuse new users (who aren't already subscribed to their mailboxes with the INBOX prefix) by listing the entire tree twice (parented at the root and at INBOX.)
This configuration seems to provide what I want:
mail_location: maildir:~/mail namespace: type: private separator: . prefix: INBOX. inbox: yes hidden: yes namespace: type: private separator: . list: yes subscriptions: yes
...except that, when a legacy user tries to delete a mailbox under INBOX, Thunderbird (at least) renames the mailbox to make it a child of Trash at the root, e.g.: tag123 RENAME "INBOX.test" "Trash.test" tag123 NO Can't rename mailbox to another storage type.
I was a little surprised that it didn't work at first, since they're both using the same (default) mail_location, but I see why it doesn't work after looking at the code. Is there any chance cross-namespace (and even cross-storage _type_) wouldn't eventually be supported? (I guess that the big problem is making cross-type renames appear atomic to clients.) Is there a better way to do what I'm trying to do?
