Indeed, though by "sources" I was referring to ebay, paypal etc, and that emails from these should always be treated with suspicion. It may be genuine ebay or paypal correspondece but it very often isn't. Especially if it's warning you about security or asking you to enter personal details.

A common one is where you're informed that someone has been using your account and you must log in and perform "verification".
