Internet Mail Server Overview
Exchange with the Internet mail connector can support standard internet POP3/SMTP clients and, with Internet information server, allow industry expert to read email with a web browser. A mail server is the email equivalent of a phone company’s “central office switch.” Using the same analogy, a mail client is the email equivalent of a telephone desk set. Few users of the lowly telephone realize just how little of the overall telephone system is in their desk set, and what complexity lies hidden behind the little hole in the wall that it plugs into, that makes it work. Similarly, most people think of the mail client program as the “email software,” without any real knowledge of what goes on behind the scenes to make that client program useful. The various post office processes must be installed and running on a computer that is always running and connected to the Internet.
