How to change the latest version of Mail to act like it did in 10.3?

I don't like how it puts all the inboxes together. I liked it better in 10.3 where the inbox was seperated out by all the other folders that went along with that e-mail account.

The only thing I can think of is to find someone still on Panther and get them to send you their Mail app. I'm pretty sure that it will work on Tiger. But MAKE SURE you back up the one thats one your computer now just incase you want to switch back or the Panther version doesn't work.

I can live with it, I just figured there would be an option to go back to the old way, but I have looked everywhere.
