This warning includes your systems administrator, who NEVER needs your password. One day I received an e-mail from " Support@Waidele.info This e-mail address is being protected from spambots. You need JavaScript enabled to view it ", saying they needed my password for maintenance, and if I did not go to a webpage and give it to them, they would suspend my account. As it turns out, I'm the one in charge of "waidele.info" — so I'm the one who gives out accounts and does maintenance. Things might have ended differently if I had had an account with googlemail.com or aol.com. Then the senders would have called themselves " support@aol.com This e-mail address is being protected from spambots. You need JavaScript enabled to view it " and I might have been fooled.
