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"
