email problem with Mail Aug 17, 12, 5:36 a.m.

Hello Guys,

Is there a reason when I get an email I get this on Mail on my laptop. But then if I forward it to say gmail it shows correctly?

What would be the reason I get all this?

Is there a setting I have to click in the Mail software?

Thanks in advance
