Whats the difference between inspool and folder space?
E-mail sent to your (server) mailbox resides in the server’s inspool folder and stays there until you remove it. With POP, you use e-mail client to connect to the server and download mail to your computer. POP Example With IMAP, you use e-mail client to connect to the server and view mail in your inbox. You can then download mail to your computer, or to mailboxes on the server. The server mailboxes are located in your folder space, which is separate from the inspool space.
