SMTP is a standard protocol that allows you to send and receive electronic mails. The protocol is simple to use and is supported by all major email 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 directly to the server. It then replaces them with one. This is called "dot stuffing".
Message Id
SMTP uses a message identifier to identify the original message. The identifier must not be machine-readable, and must conform to the msg ID specification format. The identifier is typically a single word or phrase that summarises a message and allows the receiver to know what it is about. A message identifier may also include a text comment.
Message body
The Protocol SMTP Message bodies are made up of several parts. The first is the header line. 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 must also contain a To and From line, and may contain a Subject line. The SMTP head line is part of the actual mail messages and differs from SMTP command.
RCPT command
The RCPT command identifies a mail relay server. Before sending the message, the relay host needs permission from 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 signal signals the beginning of a new message. A header and a body make up the message. If the message has been received successfully, the server may reply with a 250 code.
QUIT command
To end a session using SMTP protocol you can send a QUIT Command. SMTP servers can detect the QUIT request and will send a 221 “goodbye” message. This message will close the TCP link between the sending and receiving devices.
RCPT
The RCPT protocol for SMS is a standard protocol that allows you to send SMS messages over the Internet. 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 must contain no more than 160 characters at 7-bits and 70 Unicode symbols. However, there are ways to send longer messages. First, divide the message into smaller segments. Next, encrypt the text message.
DATA
The DATA command starts the transmission of the mail message body. 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. You can also include a single line in your message body, which is made up of only one period. This is also known as dot stuffing. When a client sends two periods, the server responds with one period.
