What at first I thought was an NDR attack (when I went to change my recipient filtering I learning that it had already been applied and everything was in place to prevent NDR), I believe is a Directory Harvest Attack - the exchange que is enormous and it seems from wireshark that someone is trying to guess common names on our domain. Does anyone know the series of steps required to stop this attack and clean our system? (our network is 100-200 clients) Thank you
