Mac mail, how do I get individual sent boxes?

[Treesie]

I have set up Mail on my Mac Air. While I have 2 mailboxes set up successfully I only seem to have one sent box which all mail box sent items are going through. This is a pain to sort through. How do I get each mailbox its own sent box? Thanks in anticipation.

Addition.... just had another go and I have 2 mailboxes but only one generic outbox and one generic sent items box.

Click the triangle next to Sent to pop down the Sent boxes for each a/c
