Its pretty common to see people these days making use of the Internet to interact with other individuals from opposite sides of the globe. They would send each other electronic mail, which is certainly a more convenient alternative to snail mail. Youre not paying anything extra for such a service, and the response time is simply quite fast. Of course, emailing has certainly become the gold standard when it comes to efficient communication over the World Wide Web, allowing people to get in touch with each other regardless of wherever they may be on this planet. However, this process is made possible by the SMTP (Simple Mail Transfer Protocol), an email server which is dedicated entirely to sending all your outgoing messages to your intended recipients. How does it work, though?
Every single instance of you sending an electronic message to someones inbox, your personal email client or web-hosted service (i.e. Gmail, Hotmail, Yahoo Mail) establishes a connection with the SMTP server in order to push through with the delivery of the message. The email server of your ISP (Internet Service Provider) will get to interact with other email servers across a variety of networks to determine the exact domain name of your recipient. The mail is converted into numerous packets of data which are then hopped off to several of these networks in an effort to go through multiple streams of information which lead to the domain name that the message was intended for. Once that has been detected and confirmed, the mail will then arrive to the persons inbox. Come to think of it, what may seem like a simple process actually consists of several much simpler processes that work together in order to carry out the task of sending email. Thus, this is how sending email through the Simple Mail Transfer Protocol works.
