A mail server is a computer with a program that knows how to handle mailboxes, sending and receiving mail.. . POP is now only POP3 (POP, version 3); it's the protocol that allows you to download mail from a mail server. . SMTP is the protocol that allows you to send mail to a mail server.. HTTP mail is not really mail at all; it's just an interface, a program that transforms what you enter into a SMTP message to send, or is able to read POP3 to display to you the contents of your mailbox.
