SMTP is a standard protocol that allows you to send and receive electronic mails. The protocol is easy to understand and is supported in all major email programs. The protocol features line-by–line transmission and an ending-of-data sequence which consists a new-line followed by a stop. A line within the message body must contain a period. When this occurs, the client sends two periods to the server, which replaces it with one. This is known as "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 usually a phrase or word that summarizes the message and tells the receiver what it is about. A message comment can be added to the identifier.
Message body
The Protocol SMTP Messagebody is made up several parts. The SMTP header line is a readable string of text that contains a keyword, followed by a colon, and a value. Some header keywords are required and others are optional. The SMTP header line must also contain a To and From line, and may contain a 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 identifies a mail relay server. This relay host seeks permission from the server before transferring the message. A 354 response code usually indicates that permission has been granted by the server. 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
In Smtp protocol, the DATA command signals that a message has begun. The message is made up of a header, and a text body. If the message was received successfully, the server will respond with a 250 response code.
QUIT command
Sending a QUIT command can be used to end a session with SMTP. SMTP servers can detect the QUIT command and will issue a 221 "goodbye" message to the receiving device. This message ends the TCP session between the sending device & the receiving device.
RCPT
The RCPT protocol to SMS allows you send SMS messages over the Internet. This protocol uses RFC822 in order to encode the contents of an SMS. It also requires a minimum number of bytes. The maximum number of characters per SMS message is 160 7-bit and 70 Unicode characters. But, you can send longer messages. First, divide the message into smaller segments. Next, you will need to encrypt the message.
DATA
The DATA command initiates transmission of the mail message body. 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. The message body can also contain a single line that is composed only of a period. This is known to be dot-stuffing. The client may send two periods, and the server will reply with one period.
