[Dovecot] Deleting a mailbox and all its children

I'm looking at scripting a mechanism to delete a mailbox, which is easy with 'doveadm mailbox delete' -- however it gets complicated when there are children of arbitrary depth, for example, I may have this:

restored.daily1.INBOX restored.daily1.Sent restored.daily1.Mystuff restored.daily1.Mystuff.foo

I would like to delete the 'restored' mailbox and all its children (and unsubscribe the folders), but the 'doveadm mailbox delete' command wont delete any children.

I'm surprised that there isn't a -r (recursive) option to 'doveadm mailbox delete', but perhaps I am missing the easier way to handle this?

thanks for any ideas or suggestions! micah
