POP3's not great for that - there's only one serverside mail folder, not much state (I think you can mark things as read maybe - or maybe that too is client side). _If_ you're keeping your email server side, IMAP is a better choice.
AFAIK POP servers don't keep any per-message state, nor can you download messages selectively, nor indeed download only the headers as you can with IMAP.
