I got one of these today. It was sent to my BTC-E email address. (I have my own domain, so I sign up with every service under a different email address.)
I wonder how they got hold of that?

This would make the origin of the problem pretty much clear. On the other hand, while BTCe is a bit shady, I cannot explain how the connection to the mails being sent through coinbase servers can be drawn
