Um, there's *nothing* in POP that requires "a download of the entire  
mailbox to check for new messages".

The copying of mbox files you probably mean is a feature of POP servers  
which use mbox mail files, which certainly isn't the best design in the  
world. Try the same with, say, Maildir, or any other mailbox format that  
doesn't require you to rewrite the whole mailbox if you just want to, say,  
delete a message, or change a status flag on a message, and the problem  
should go away.

Don't blame the protocol for a suboptimal implementation.
