Email down since afternoon 11/30/2016. Can't send, can't save, don't get new e-mails (if any), stuck with a new outgoing e-mail in flight.

Email down since mid afternoon, Chicago area, CST.  Creating an outgoing e-mail, but can't send it, can't save it, don't get list of any potential incoming e-mails.

That new Dovcot e-mail system DOES NOT WORK!  Bring back Zimbra.  That wasn't great either, but it always worked.  Dovcot does not go "Bong" when a new e-mail comes in.  I gotta check every so often to see if anything has come in. PITA.
