Fixing discussion lists to work with new Yahoo policy

Yahoo turns on images by default for RP certified IPs

ReturnPath announced today that images and links from Return Path Certified senders are turned on by default in the Yahoo mail interface. This affects many of the other domains using Yahoo for mail hosting including Bellsouth, SBC, Rogers, BT Internet and Rocketmail.
