Today my wife received an e-mail, apparently from PayPal, notifying her that a payment was being made from her PayPal account for a purchase of about $30, and with a link to click if she wanted to dispute it. But... she's never opened a PayPal account. She was using iOS Mail on her iPad. As far as I can tell (I use iOS Mail on my iPhone, too), there's no option to view the source of a message so as to inspect the links. I had her forward the message to me, so I could open it in Gmail's web interface on my desktop Mac. As soon as I did so, I burst out laughing. The "From" header, which on iOS mail showed only "From: PayPal", in Gmail read "From: PayPal <email@example.com>". Choosing "view original" showed that the link to the "Resolution Center" pointed to employeeportal.net-login.com. Uh... I don't think so.
