Protocols Used

SMTP : Whenever you send a piece of email ,youre-mail client interacts with the SMTP server to handlethe sending . The SMTP server on your host may

have conversations with other SMTP servers toactually deliver the email.

IMAP : The Internet Message Access Protocol is aprotocol that many enterprise email servers employ, itoffers a far richer set of functions than POP or even

SMTP. With POP the premise is that the user isresponsible for the storage of e-mail ,where as withIMAP the server is. IMAP offers a folder structure forthe user to interact with and all messages are storedon the server with technically no need to downloademail to the users local machine.
