Native Mail App and Incredimail

[wastedagen]

I like the native mail app and it serves it's purpose. But when I receive emails from friends and family that use Incredimail I get nothing but a blank page. My only option to read these are to use the Yahoo Mail app. Which I don't like cos it kills the battery.

Is there a work around to be able to view these emails or am I stuck with Yahoo Mail.

Thanks In advance.
