Mail Glitch

I have a new RMBP with OSX lion on it. When I restored from my time machine back up (snow leopard) I opened the new mail application and noticed a problem. Sometimes (not all the time) when I get an e-mail it shows up with the correct subject and sender but the body comes from a message I received long ago. As you can guess apple was not sending me an e-mail about blackboard but the body of a message from months ago showed up. This is difficult because it means I can't read the actual e-mail message.

Has anyone else had this problem?

 

Thanks for the advice. I will try that and let you know how it goes.

It fixed some of the old messages and broke others that were not broken before. Some incoming mail still is glitched.
