+  # Lazy expunge plugin. Currently works only with maildirs. When a user
+  # expunges mails, the mails are moved to a mailbox in another namespace
+  # (1st). When a mailbox is deleted, the mailbox is moved to another namespace
+  # (2nd) as well. Also if the deleted mailbox had any expunged messages,
+  # they're moved to a 3rd namespace. The mails won't be counted in quota,
+  # and they're not deleted automatically (use a cronjob or something).
