If you have a nnml group, you can see its .overview file, that is
just NOV.  It's a common format that most news servers use when
communicating with clients.  It improves the performance.  So,
disabling it is not a good idea unless it malfunctions in the
server.  See also `nnml-nov-is-evil' and `nntp-nov-is-evil'.
