Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

TCP/IP Electronic Mail System Overview and Concepts

Electronic mail in the TCP/IP protocol suite is not implemented as just a single protocol or technology. Rather, it is a complete system that contains a number of related components that work together. These include standards defining methods for addressing and message formatting, and a number of protocols that play different functions in implementing electronic mail messaging. Before proceeding to examine each of these pieces, it makes sense to start with an overview of the system as a whole.

In this section I provide an introductory look at TCP/IP electronic mail, to help you understand the system, how it works, and how different components fit into it. I begin with an overview and history of e-mail and its implementation in TCP/IP. I provide a general overview of the steps involved in the e-mail communication process. I conclude with a more specific discussion of the communication model used in TCP/IP and the roles played by various TCP/IP devices and protocols in the sending and receiving of electronic mail.
