Good day, Monica did a good job explaining what SMTP means. Maybe a bit more of an explanation concerning Internet protocols might be useful.

Also known as a communications protocol or network protocol, this is a set of standards that assures that different network products or programs can work together. Any product that uses a given protocol should work with any other product using the same protocol. Protocols dictate the "whats" and the "hows" of the various systems on the Internet. The success of the Internet, its very existence, in fact, depends on people voluntarily agreeing to configure their hardware and software to the TCP/IP (Transmisison Control Protocol/Internet Protocol) standard. How do protocols work? Take FTP (File Transfer Protocol) as an example. When you contact a computer to download a file, the computers communicate with each other in a series of pre-agreed-upon rules. The "conversation" between the computers goes something like this: "I want that file," "here it comes," "didn't get it, please resend," "here it is again," "got it," "goodbye," "goodbye." SMTP works the same way and sometimes a computer or a server is just cranky and the "hand shake" fails so the message gets bounced. One more common protocol, HTTP (HyperText Transfer Protocol). This is the protocol or method by which hypertext files are transferred across the Internet. Hypertext files are a way of presenting information in which text, sounds, images, and actions are linked together in a way that allows you to jump around between them in whatever order you choose. You'll see this protocol on most of the TV advertisements "See our web site at http://etc.com." Net browsers generally use this protocol most. I'm done. This is probably too much but in my view it doesn't hurt to have a better view of the environment in which we find ourselves. Take care, Jeff Jones part CG for Becky, Seattle, WA. [log in to unmask]
