Where did my mailboxes go?

[Cave Man]

OK, the Lion install went fine, but I am already considering moving back to Snow Leopard. One thing in particular is that all of my mailboxes have disappeared. Is there a way to get them back?

Edit: Doh! Just found it. I think this should have been enabled by default!

Do you mean the sidebar or the actual folders? If you're talking about the sidebar, go to View > Show Mailbox List
