A medium of fastcommunication
SMTPis a protocol to increase the communication rate between the mail server andthe mail received. A Transmission Control Protocol is typically used toestablish the communication. The mail receiver uses command strings forsupplying the necessary data by a data stream medium. The commands aregenerally originated by a particular SMTP client and receive a reciprocalresponse from a SMTP server and finally the session is opened and the emessages are exchanged in a smooth flow. This transaction system consists ofthree major commands or reply sequences. These commands are,
· Mailcommand- This command is used to establish and construct a return address. Thisis an address established for bounce messages.
· RCTPcommand – This particular command is generated to establish a receiver of themessage. It can be used several times, each for every recipient.
· DATAis issued to send message text. It is the main theme of the message. Itcomprises of a header and a message body, a blank line segregates both theseparts. In general, sense DATA is a group of organized commands. Each server canprovide either positive or negative reply.
It is implemented to access andoperate mainly over internet port 25. Today after repeated technologicaladvancement an alternative of SMTP is widely in practice in Europe is X.400.Even many servers these days are highly demanding ESMTP or Extended Simple MailTransfer Protocol, which enables the sender the multimedia files as e-mails.
