Last night I received two very disturbing emails. The first was: Security alert from server The number of ISPConfig administrator users has changed. Old: 1 New: 0 and one minute later: Security alert from server The number of ISPConfig administrator users has changed. Old: 0 New: 1: Delivered-To: root@localhost Received: from localhost (localhost [127.0.0.1]) Is this a critical alerts? Thanks, Michael
