SMTP, a standard protocol to send and receive email messages, is used. It is easy to use and supported by all 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. One caveat is that lines in the message body cannot contain 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
SMTP uses a Message Identifier to identify the original message. The identifier must also be machine-readable. It must adhere to 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. An identifier for a message can also contain a comment.
Message body
The Protocol SMTP Messagebody is made up several 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 required and others are optional. The SMTP header must contain a To, From and Subject line. The SMTP header is part and parcel of the actual mail message. This is different than SMTP commands.
RCPT command
The RCPT command for protocol SMTP identifies a mail relay host. Before transferring the message, the relay host requests permission from the server. 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 message contents are then sent to the recipient via SMTP.
DATA command
The DATA command signalling the start of a message in protocol Smtp is the DATA command. The message is composed of a header and a body. If the message passes successfully, the server will return a 250 response number.
QUIT command
Sending a QUIT command can be used to end a session with SMTP. SMTP servers are able to detect the QUIT commands and send a 221 "goodbye” message to the receiver device. This message terminates the TCP communication between the sending device, and the receiving device.
RCPT
The RCPT protocol is used to send SMS messages via the Internet. This protocol uses RFC822 in order to encode the contents of an SMS. It also needs a minimum amount of bytes. Each SMS message has 160 7-bit characters, and 70 Unicode character. You can send longer messages, however. Split the message into smaller pieces. Next, you must encrypt the text message.
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. A single line can be included in the message body that contains only a period. This is called "dot-stuffing", which occurs when the client sends two periods to the server and the latter replies with one period.
