Like everybody else, I get unwrapped messages, and SmartWrap has worked great. Then, with Leopard, my MacBook Pro couldn't get it to install the Mail.app pllugin. The developer, Sanford Selznick, was incredibly responsive and diligent in tracking down and fixing the glitch. So now it works great once again! I can't recommend it enough - and please don't forget to register it! Sanford deserves the support of all of us!!!
