The
     anti-phishing features in Windows Mail help protect against phishing
     messages, which attempt to trick you into revealing personal or financial
     information. When Windows Mail detects a possible phishing message, it
     allows you to view the message, but it blocks any links or dangerous
     content that might be in the message. You can choose to delete a message,
     or to allow a message that you know is safe.
