                  transferred between computers.

                  INTERNET MESSAGE ACCESS PROTOCOL (IMAP)

                  IMAP stands for Internet Message Access Protocol. It is an e-mail protocol that stores e-mail
                  messages on a mail server and allows the user to view, access and manipulate the messages on

                  the mail server from their computer.

                  SIMPLE MAIL TRANSFER PROTOCOL (SMTP)
