Recently NETDOOR customers received notifications of pending maintenance that requested your account information. The type of message you received is called "phishing." It is a ploy to get personal information from you if you were to respond to the message. They send to random addresses at any domain such as @netdoor.com and hope for the best. These type of messages propagate the Internet all the time and take on many different forms. As in any Internet scam as long as you do not reply to it your information is not in jeopardy.
