What mail protocol is smtp

smtp is a protocol for email transmission. SMTP is a mail service based on the FTP file transfer service. It is mainly used to transfer mail information between systems and provide notifications about incoming letters. The SMTP protocol belongs to the TCP/IP protocol family, which helps each computer to find the next destination when sending or transferring letters.



SMTP is a protocol that provides reliable and effective email transmission. SMTP is a mail service based on the FTP file transfer service. It is mainly used to transfer mail information between systems and provide notifications about incoming letters.

SMTP is independent of specific transmission subsystems and only requires reliable and orderly data flow channel support. One of the important features of SMTP is its ability to transmit mail across the network, that is, "SMTP mail relay."

Using SMTP, mail transmission between the same network processing process can be realized, and mail transmission between a certain processing process and other networks can also be realized through a relay or gateway.

Function

SMTP is a set of rules used to send mail from the source address to the destination address, and to control the way the mail is transferred. The SMTP protocol belongs to the TCP/IP protocol family, which helps each computer to find the next destination when sending or transferring letters. Through the server designated by the SMTP protocol, we can send E-mail to the recipient's server. The whole process only takes a few minutes. The SMTP server is a sending mail server that follows the SMTP protocol and is used to send or relay emails sent by users.

SMTP is a protocol that provides reliable and efficient email transmission. It is a mail service built on FTP file transfer service, mainly used to transfer mail information between systems and provide notifications about incoming letters.

One of the important features of SMTP is that it can transmit mail across the network, that is, "SMTP mail relay." Using SMTP, mail transmission between processors on the same network can be realized, and mail transmission between a processor and other networks can also be realized through a relay or gateway. A mail exchange server with a Domain Name Service (DNS) function can also be used to identify the next hop IP address of the transmitted mail.
