[Windows Mobile Software Development] RoryB:
Okay, I got more methodical. I changed the images to be 200 pixels wide with allow distortion so the height stayed the same. I also changed the height of the hh_email_background.png to be 210 pixels tall. I changed the xml to read this way to get as much email preview as possible.
