How does this email scam work? This is a legit "Delivery Status Notification" from Google. But the Facebook email it's quoting is actually an image (served from _hzdavmzkdfcacdjq-.bluelight.com.de/img/SKJfVGrmKhOxlKJq) and has a mailto: link with a bunch of random email addresses in it. Is this just a worm or an actual phishing/scam/malware thing..?
