POP3 is only useful if you plan to always get the whole mail batch
from the server and delete it there. IMAP gives you much more
flexibility (and besides it has this IDLE feature, where the client
can keep the connection open and get notified -- i.e. instant mail
delivery without polling).

I know, with pop3 you can theoretically leave your mail at the
server, but... the protocol makes it very difficult to see that
you don't download mails twice, or many times.

If it's working for you, don't touch it. For what it was conceived, POP3
is fine!

You can do that with IMAP too.

Yes. What's nifty is -- you can decide *when* to delete things (this
way, I try to keep mails around in the server for one extra round, to
allow for my client to have done a backup in the meantime).

Heh. Welcome to POP3 and its mysterious UIDLs :-)
