SMTP (Send and Receive Mail Transfer Protocol) is a standard protocol used to send and retrieve electronic mails. The protocol is easy-to-use and supported by all major mail clients. It includes line-by–line transmission. The protocol also has an end-of–data sequence. This consists of a complete stop and a new-line. A line within the message body must contain a period. If this happens the client sends two periods in the message body to the server. The server replaces it by one. This is known as "dot-stuffing".
Message ID
SMTP uses a message identifier that 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 bodies are made up of several parts. The first is the header line. The SMTP head line is a string of text that contains a keyword, followed with a colon and a valued. Some header keywords must be included, while others can be left out. The SMTP header line must contain a To line and a From line. It may also include a Subject line. The SMTP header is part and parcel of the actual mail message. This is different than SMTP commands.
Command RCPT
The RCPT command for protocol SMTP identifies a mail relay host. Before transferring the message, the relay host requests permission from the server. A 354 response code usually indicates that permission has been granted by the server. 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. A body and a header make up the message. If the message was received successfully, the server will respond with a 250 response code.
QUIT command
To terminate a session using the SMTP protocol, you can send a QUIT command. SMTP servers are able to detect the QUIT commands and send a 221 "goodbye” message to the receiver device. This message ends the TCP session between the sending device & the receiving device.
RCPT
The RCPT protocol allows SMS messages to be sent over the Internet using a standard protocol. To encode an SMS message's content, this protocol uses RFC822. It also requires a minimum number of bytes. Each SMS message is limited to 160 7-bit characters and 70 Unicode characters. There are other ways to send more messages. Split the message into smaller pieces. The next step is to encrypt your text message.
DATA
The DATA command begins the transmission of mail message bodies. 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 called "dot-stuffing", which occurs when the client sends two periods to the server and the latter replies with one period.
