It's a server side option too. As I mentioned above you have the option
to retain server side.

Does POP3 really re-read all retained messages? I cant say I ever saw a
POP3 client freeze on my gmail pop3 connection and there are thousands
of thousands there. That said I now use IMAP/offlineimap.

I thought IMAP was more about dual direction and multi client syncing
- nothing to do with retaining messages as such. Certainly its advisable
to leave emails on the server for obvious reasons. In this day and age
of multiple laptops, PDAs, Smartphones etc, the low price of storage, it
would be ludicrous NOT to keep a central repo of your email. (obviously
filtering and removing spam etc).

Certainly I dont want one client to download email which I am yet to
read and then not be able to pull that email up on another client.
