That is correct. However, if you give a LIST command to a POP server it will return a list of messages and each message will have a unique ID. That ID is guaranteed to be unique through different sessions. So if you store a list of IDs on the client side, you can determine if a message is new. And if it is new, it is unread. > To count unread messages, we will need to find something that can talk to the server > through through IMAP. Telnet can.
