Riposte solution
Your IMAP NOTIFY command requested an event type the server doesn't support or recognize. If you're not directly using NOTIFY, Riposte wouldn't trigger this. But if it happens, the solution is to adjust the set of events you're listening for. Use only events the server supports. In summary, correct the NOTIFY usage or ignore unsupported events.
