Being an Android owner I have a Gmail account. Checking my spambox the other day I found this message:

On the face of it a simple phish - Google's filter obviously thaught so, but it is in fact a genuine e-mail sent by Google thenselves. Their own SPF and DKIM tests resulted in a pass, as revealed in the headers. The link is to https://wallet.google.com, so that is also genuine. So if you receive spam, be sure to go through it, you never know what you might find!
