A friend of mine recently forwarded me an email he received that looked like it had come from me.
Except, of course, it hadn’t. It was a complete forgery, and not a very good one at that.
I am both slightly honored that I’m worth forging, and quite annoyed that someone actually did.
We’ll look at the message and all the clues it contains that make it a fairly obvious fake, and then generalize those clues to help you separate spam from legitimate email.
