|POP is a simple protocol that only allows downloading messages from your Inbox to your local computer.||IMAP is much more advanced and allows you the user to see all the folders on the mail server.|
|The POP server listens on port 110, and the POP with SSL secure(POP3DS) server listens on port 995||he IMAP server listens on port 143, and the IMAP with SSL secure(IMAPDS) server listens on port 993.|
