Application protocol designed to transport mail across networks. In the Internet it works in the TCP/IP stack with the installation of connections through TCP port 25.
To send an e-mail message, the client sends the request to the Server SMTP connection. After establishing the session TCP SMTP server sends the client a special message about connecting and managing the connection between two computers is performed by the client through a set of special commands it sends to the server. When working with Simple Mail Transfer Protocol (SMTP) as clients can serve both users and hosts. When you create a mail user is a customer of the local host. After sending the e-mail message is the local host is in the process of message delivery and acts as the client-sender SMTP to a remote host. The sender-SMTP determines the recipient's host address portion of the address after @, converting it to an IP address by using DNS.
