Just as there is far more taking place
in a real Post Office and in the delivery of regular mail, there is also far more taking
place in the delivery of electronic mail. However, for our purposes here, this basic
analogy will suffice. This example describes the process of INTERNET email. Some popular
tools which are used to create, send, and receive electronic mail over SMTP are Eudora,
Netscape mail, and Pegasus.
As noted in the above analogy, SMTP stands for Simple Mail Transport
Protocol. This is the standard for delivering email messages over the Internet. As the
name suggests, it is a very SIMPLE protocol. Not only is it simple, but it is limiting in
Companies such as Microsoft and Lotus have therefore created their own
proprietary software products for the purpose of managing electronic mail for large
companies. Microsoft developed Exchange Server, and Lotus created Notes & Domino
Servers. Although these products make use of SMTP to send email to other companies on the
Internet, they do not use this protocol to exchange documents and email messages between
associates within the company.
Some of the greatest advantages to using one of these products for
electronic mail within a company are their added capability of managing shared documents,
schedules, conference rooms, global distribution lists, and other public resources.
