Why do emails with background graphics not display correctly in email?

[Major Henderson]

When someone sends an email with "stationary" or background graphics, the email chops off and just displays about 1/4 of the message. This is horizontally, not vertically.
The emails display normally on the Mac.

I was able to get the emails to display correctly by using the Blue Mail app instead of the standard supplied email app.
