I know Facebook do some charitable stuff, but really that does not extend to dishing out $600,000:00 USD to total strangers after an email like this one... nor do they email you from a gmail account!

This is some sort of scam, probably an attempt to get hold of your bank details or an identity theft thing. Either way, it's not good, and it sure isn't genuine!
