Do you *really* think that pop3 is *widely* used to do not get and delete 
the messages from the server? I don't think so, and moreover, I would not 
recommend to keep the messages on it because it can cause a big mess on 
the client side, better use imap.

Pop3 was not designed to keep the messages on the server, having such 
option is not the norm but the exception (many e-mail server do not have 
it enabled) and as I said, it does not work very well... 

P.S. Recommeded lecture: 

- RFC1939, chapter "8. Scaling and Operational Considerations"
