Most email clients (possibly all of them, I'm not sure) save the ID number
of email messages it has downloaded from a mailbox. If the client is set to
leave email on the server, the client actually recieves a list of ALL the
emails in the mailbox when it checks for new mail because the server has no
way of knowing which messages have already been read or not. The client is
then responsible for downloading messages that haven't been downloaded yet.
So, in essence, you are correct - the server is sending a listing of ALL the
messages in the mailbox, not just the unread ones, because it has no way of
knowing which are which.
To be honest, I have webmaster accounts on 4 different domains on my server,
my client in all cases is set to leave mail on the server, and I have
noticed no performance degradation with version 7.02 even though one of the
accounts has nearly 2000 emails in it (I should probably delete a few
hundred of those anyways). If anything, it seems faster since the upgrade.
