Protocol SMTP

By Trey Gordon 22 June, 2023 2 mins read

SMTP (Send and Receive Mail Transfer Protocol) is a standard protocol used to send and retrieve electronic mails. This protocol is easy to use, and it is supported by most major email clients. It features line-by-line transmission as well as an end-of data sequence that consists of a newline and a full stop. The only restriction is that the message body may contain no more than one period. If this happens, the client sends two periods directly to the server. It then replaces them with one. This is known as "dot stuffing".

Message ID

In SMTP, a message identifier identifies the original message. Machine-readable identifiers must follow the msg id specification format. The identifier is usually a phrase or word that summarizes the message and tells the receiver what it is about. A message identifier can also contain a text comment.

Message body

The Protocol SMTP Message Body is composed of many parts. A readable string of text containing a keyword, followed closely by a colon and a value is the SMTP header. Some header keywords are mandatory while others are optional. The SMTP header lines must contain a To-and-From line as well as a Subject line. The SMTP Header line is a part of the actual mail and differs from SMTP Commands.

RCPT command

The RCPT command for protocol SMTP identifies a mail relay host. This relay host seeks permission from the server before transferring the message. Typically, the server will respond with a 354 response code. Once this permission has been granted, the sender starts transferring the mail data line by line. The contents of the message are copied to the mailbox by the recipient SMTP server.

DATA command

In Smtp protocol the DATA signal signals the beginning of a new message. The message is composed of a header and a body. If the message was received successfully, the server will respond with a 250 response code.

QUIT command

Send a QUIT request to end a session via SMTP. SMTP servers detect the QUIT command. They will send a 221-word "goodbye" message. This message ends the TCP connection between the sending device and the receiving device.

RCPT

The RCPT protocol allows SMS messages to be sent over the Internet using a standard protocol. This protocol uses RFC822 to encode the content of an SMS message. The minimum bytes required for this protocol is also minimal. Each SMS message has 160 7-bit characters, and 70 Unicode character. However, there are ways to send longer messages. You must first split the message into smaller messages. The text message must then be encrypted.

DATA

The DATA command begins the transmission of mail message bodies. The message is sent line-by-line to its destination. It ends with an end-of data sequence that includes a new line and a complete stop. The message body can also contain a single line that is composed only of a period. This is also known as dot stuffing. When a client sends two periods, the server responds with one period.
