I get more than my share of unwanted e-mail messages of all types, but a new (to me at least) scam appeared in my in-box today. The subject was "New User Letter" and the message appears below with the ID numbers changed as a precaution.
By the time I looked into it, the IP address seemed to have been taken out of service--it was unreachable both with a browser and the ping command.
One reason to lookout for this sort of thing is that the Web page it sends you to might try to install malicious software on your computer. My recent blog trilogy on DropMyRights is one way to defend against this type of attack. See "DropMyRights" Part 1, Part 2 and Part 3 .
My personal Web site has more "Examples of Bad E-mail Messages". The important lesson is to always be skeptical about e-mail messages, and, not to judge them based on the from address. It is very easy to forge the from address in an e-mail message.
