To enter the e-mail address of your e-mail address and send it to the e-mail address

The e-mail client (email software) contains certain e-mail message and message information to the SMTP server (SMTP server handles outgoing mails SMTP refers to the Simple Mail Transfer Protocol) Which SMTP server used is configured in the email software. Most people use the ISP provided by the Internet Service Provider. Or if you use web emails such as Hotmail or Yahoo email, you do not have SMTP server control – built-in.

The SMTP server accepts the e-mail, finds the target server's IP address, packs packets and sends packets to a destination via a series of "hopp" (usually a series of very powerful routers). The way your email reaches through the Internet is determined by the different routers. Routers used for Internet routing have been compared to supercomputers. They explore the different paths of the destination and determine the best route. Each packet can use the same route or some I'm going through a route, the router may decide to have too much traffic along the way and send the other packets by another route or several other routes.

After receiving all packets, the destination server (usually a "POP" server) connects the packets and places the email in a special file and waits for the recipient to request an email. E-mail servers are having a real conversation. As you can see, from below they are very polite. This is a real conversation with the jammed identification information. The sending server connects to the destination server. He says hello. The target server responds with ELHO. They are still based on their first name. The sending server says, "You have a message for a man and that's great."

The destination server looks up the email address and looks at whether or not you want and can receive e-mail for the recipient. Then he tells the sending server. "Okay, send it"

The sending server says "Ok, I'll send the message." You will know when it happens when two carriage return lines (CRLFs) look back from the back. The receiving server then acknowledges receipt of the message and the end of the conversation.
