SMTP is a standard protocol which allows for the sending and receiving of electronic mails. This protocol is easy to use, and it is supported by most major email clients. The protocol includes line-by -line transmission, and an end of data sequence. This sequence consists in a new line and full stop. Only one line can be contained in a message body. If this happens the client sends two periods in the message body to the server. The server replaces it by one. This is called "dot stuffing".
Message ID
SMTP uses a message identifier that identifies the original message. The identifier must support the msg_id specification format and be machine-readable. Typically, the identifier is a sentence or word that summarizes the message to let the receiver know its contents. A message identifier could also include a comment in text.
Message body
The Message body for Protocol SMTP is composed of several parts, the first of which is the header line. The SMTP header is a readable string containing a keyword, followed a colon, then a value. Some header keywords are required and others are optional. The SMTP header lines must contain a To-and-From line as well as a Subject line. The SMTP header line differs from SMTP commands in that it is part of the actual mail message.
RCPT command
The RCPT command identifies a mail relay server. Before transmitting the message, this relay host asks permission from the server. A 354 response codes is typically an indication that permission has been granted. 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
In Smtp protocol, the DATA command signals that a message has begun. The message consists of a header as well as a body. The server will reply with a 250 response code if the message has gone through successfully.
QUIT command
Send a QUIT request to end a session via SMTP. SMTP servers will detect the QUIT command, and issue a 221 message of goodwill to the recipient device. This message ends the TCP connection between the sending device and the receiving device.
RCPT
The RCPT protocol for SMS is a standard protocol that allows you to send SMS messages over the Internet. This protocol uses RFC822 as a code to encode an SMS message. It also requires a minimum of 256 bytes. Each SMS message is limited to 160 7-bit characters and 70 Unicode characters. But, you can send longer messages. First, split the message in smaller parts. Next, encrypt the text message.
DATA
The DATA command activates the transmission of your mail message body. The message is then transmitted line by line to its destination. A single line of text can be added to the body. This is called dot-stuffing. This is known to be dot-stuffing. The client may send two periods, and the server will reply with one period.
