Online Email Extractor- Working Of Email Explained

In modern history, three maybe four times, a new technology has been introduced that has radically transformed the way we communicate. First of all the invention of the telegraph by Samuel B. Morse. After sending the first message on May 24, 1844 Morse, he realized that he had marked a fundamental stage in the history of telecommunications.

We certainly can not forget the invention of the telephone (Meucci or Bell?). As an Italian, I can only recognize the paternity of the telephone to our friendly and unfortunate fellow-countryman. I can not believe that a man spends much of his life fighting for the recognition of an invention that did not actually belong to himself. And what about the invention of the radio by Guglielmo Marconi who even won the Nobel Prize in 1909.Let's not forget that our beloved mobile phone is the combination of these last two inventions. But the simplest and most extraordinary invention for the Internet people is surely the Email .

How many times on vacation we had a sense of nostalgia despite the beautiful landscape and the fun vacation we were spending.Initially we believed that this feeling was due to an Internet withdrawal crisis.As soon as you have entered the local internet-point and connected to the Net, what was the first operation we instinctively performed? Of course ... reading the mailbox!

What's so special about online email extractor?

Everyday, Internet citizens exchange billions of emails.Obviously this is the reason why, in a short time, email has become a very popular means of communication.

AN EMAIL MESSAGE


The first email message was sent in 1971 by an engineer named Ray Tomlinson. Before that it was only possible to send messages to users connected to the same machine. Tomlinson's novelty was to be able to send messages to other machines connected to the Internet using the @ symbol to designate the receiving computer.

But what's behind online email extractor?

An online email extractor message is nothing more than a simple block of ASCII characters to be inserted in a container (the envelope) and write:

    A title

    The name of the recipient

    The name of the sender.

At the beginning only quite short text messages were sent, but currently, with the possibility of including attachments, the emails have reached considerable dimensions. In any case, the messages are always made of pure text.

CLIENT FOR EMAIL

You have already received several emails in the past. To read them, use some online email extractor client program. Many people use special programs like Microsoft Outlook, Outlook Express, Eudora or Pegasus. Other users who subscribe to some free email services such as Hotmail, Yahoo or Tiscali use an email client that appears on a Web page (webmail service).

Regardless of which online email extractor client you are using, it generally performs the following tasks:

    It lists a list of all the messages in your mailbox showing the message titles.

    If you select one of the messages in the list, you can read its contents.

    On request you can create a new message and send it.

    You can also attach an attachment to your email that you are sending or save the attachment to an email you have just received.

    More complex e-mail programs have a myriad of gadgets, but the basic functions are those just listed.

A SIMPLE SERVER FOR EMAIL


Let's show now with a simple example of how an e-mail system could work. Given that you have already installed an e-mail management program on your PC, you are ready to send or receive e-mail messages. On the side of who provides the email service there is a specific program that manages the requests of the various clients. This program is called "mail server". As you know, on the provider's computer there are always active applications, called servers or demons that listen to specific ports waiting for someone to ask to be served.

The simplest possible mail server should work like this:

    It should manage a list of email accounts, one for each user who can receive mail on the server.

    It should have a text file for each account in the list.

    Actually there are many other information that the server could store in the file, such as the date and time; in any case you will notice that everything is an extremely simple process to carry out.
