It is at least 5 months since spammers use fake "delivery error" to skip the filter: http://old.reddit.com/r/cybersecurity/comments/1jzf6o2/fake_delivery_status_notification_failure_emails/ http://old.reddit.com/r/cybersecurity/comments/1jzf6o2/fake_... . I would expect more from industry-leading company. Just joking, I expect nothing from GMail team after I noticed that "block sender" option just puts emails in spam folder instead of deleting them on arrival.
