I'll give this a shot. Any solution that doesn't maintain at least the current client-side status of emails (ie, requires redownload, or new account on client) is a complete nonstarter, though.

No, IMAP and POP are just the transport mechanisms. But POP is old and doesn't keep state well. If you can, upgrade all your clients to IMAP, thunderbird will be easy to do so, and I suspect Eudora will be as well, but I haven't touched it in years.
why don't you just setup a test IMAP account and try a client?
