What is e-mail?

Often referred to as "e-mail", this term is frequently used or associated with the discussion of not only actual "mail" composition and retrieval, but is also used in the explanation of different protocols, standards, and architecture(s) associated with the electronic creation, submission, and retrieval of electronic messages.


We can see how "e-mail" is defined below;

e-mail:

noun

messages distributed by electronic means from one computer user to one or more recipients via a network.

verb

send an e-mail to (someone).


In this training unit, we'll look at how e-mail came about, the industry standards and protocols used today as well as the architecture and vernacular of how e-mail works within your Zimbra deployment.



The origin of e-mail and industry standard protocols

Dating back to the early 1960's, the first form(s) of e-mail sprouted up in the form of services like AUTODIN, a legacy data communications service developed by the U.S. Department of Defense, and MIT's CTSS Mail, where remote terminals could dial-in to share and store files on a central disk(s). Informal methods of using these type(s) of systems later evolved to pass messages between terminal users.

The first "e-mail" systems used different features and ran on different systems that were not compatible with each other; coined "host-based e-mail systems". Most of these systems required users to be logged into in the same "terminal" or "mainframe" in order for communication to occur.

Subsequent to "host-based e-mail systems" cam "LAN e-mail systems", those that ran on a local area network, which still required users to be logged into the same infrastructure. Some examples of "LAN e-mail systems" include Microsoft Mail and Lotus Notes. Further evolution allowed for these types of systems to communicate outside of an organization, assuming the same email system and proprietary protocols were in use.

Circa the 1970's, more of what we see in use today was in the origin of development. It was essential that as organizations grew larger and as technology advanced, those methods of mail exchange between remote sites or other organizations provided an avenue to transport messages of text globally via telecommunication links.

Alas, through RFC, an "Internet Message Format" was derived and published by Qualcomm. RFC5322 is not the first RFC to establish an "IMF", albeit it's the most current.

From RFC5322:

This document specifies the Internet Message Format (IMF), a syntax
  for text messages that are sent between computer users, within the
  framework of "electronic mail" messages.  This specification is a
  revision of Request For Comments (RFC) 2822, which itself superseded
  Request For Comments (RFC) 822, "Standard for the Format of ARPA
  Internet Text Messages", updating it to reflect current practice and
  incorporating incremental changes that were specified in other RFCs.
