SMTP is a standard protocol for sending and receiving electronic mails. 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 in the message body to the server. The server replaces it by one. This is "dot stuffing".
Message ID
SMTP uses a message identifier to identify the original message. The identifier must support the msg_id specification format and be machine-readable. 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 Messagebody is made up several parts. The SMTP header is a readable string containing a keyword, followed a colon, then a value. Some header keywords are mandatory while others are optional. The SMTP header line should contain a To/From line and a Subject. The SMTP Header line is a part of the actual mail and differs from SMTP Commands.
Command RCPT
The RCPT command identifies a host mail relay. Before transmitting the message, this relay host asks permission from the server. Typically, the server will respond with a 354 response code. The sender begins to transfer the mail data line-by-line once permission is granted. The contents of a message are added to the recipient's mailbox by the recipient SMTP servers.
DATA command
The DATA command in the protocol Smtp signals the start of a message. The message is made up of a header, and a text body. If the message is successful, the server will send a 250 response code.
QUIT command
Send a QUIT request to end a session via SMTP. SMTP servers can detect the QUIT request and will send a 221 “goodbye” message. This message ends the TCP session between the sending device & the receiving device.
RCPT
The RCPT protocol is used to send SMS messages via the Internet. This protocol uses RFC822 as a code to encode an SMS message. It also needs a minimum amount of bytes. Each SMS message is limited to 160 7-bit characters and 70 Unicode characters. There are however ways to send longer messages. Split the message into smaller pieces. Next, encrypt the text message.
DATA
The DATA command triggers the transmission and receipt of the mail message. The message is then sent line by line to its destination and terminated with an end-of-data sequence of a new-line and a full stop. A single line may also be contained in the message body. It can contain only one period. This is known as dot-stuffing, which happens when the client sends two periods and the server replies with a single period.
