What about moving the pop server to a high port, and configuring your 
mailbox status app to use the high port? The server will appear not to 
support pop3, but still be able to report your mailcheck info. This 
depends, of course, on what client you use for the status check.

It might be possible to check the mail spools for mailboxes with 
messages that have been downloaded but not deleted. I don't know about 
the cyrus pop3 server and how it stores info on seen/unseen messages, 
but it must do it somehow, and you must be able to get at that info.

Alternately, just look for over-quota mailboxes.
