I have been getting this mail for the last couple of days. I got pweb to take a look and they say things look ok, but I am a bit worried. This is the exact mail I am getting..... IMPORTANT: Do not ignore this email. This message is to inform you that the account has user id 0 (root privs). This could mean that your system was compromised (OwND). To be safe you should verify that your system has not be compromised. Any ideas, things I can check and stop the mail coming through? Cheers.
