The protocol for sending emails is SMTP.
SMTP is a protocol that provides reliable and efficient email transmission. SMTP is an email service built on the FTP file transfer service. It is mainly used to transfer email information between systems and provide notifications about incoming letters.
SMTP is independent of a specific transmission subsystem and only requires the support of a reliable and orderly data flow channel. One of the important features of SMTP is its ability to transmit emails across the network, that is, "SMTP mail relay". Using SMTP, mail transmission can be realized between processing processes on the same network, and mail transmission between a processing process and other networks can also be realized through a relay or gateway.
Functions of the SMTP protocol:
SMTP is a set of rules for transmitting emails from a source address to a destination address, and controls how letters are relayed. The SMTP protocol belongs to the TCP/IP protocol suite and helps each computer find the next destination when sending or relaying email. Through the server specified by the SMTP protocol, we can send the E-mail to the recipient's server. The whole process only takes a few minutes. The SMTP server is a sending email server that follows the SMTP protocol and is used to send or relay emails sent by users.

Mail exchange servers with Domain Name Service (DNS) functionality can also be used to identify the next-hop IP address for transmitting mail.
