is the abbreviated form of Simple Mail Transfer Protocol. It is a kind of
protocol used for sending e-mail among the servers. The e-mail systems that
exchange e-mails via internet use SMTP for sending the messages from one server
to some other. It is generally used to send e-mail messages from a client to
the mail server. It increases the deliverability of mails in less time.
A medium of fast
communication
SMTP
is a protocol to increase the communication rate between the mail server and
the mail received. A Transmission Control Protocol is typically used to
establish the communication. The mail receiver uses command strings for
supplying the necessary data by a data stream medium. The commands are
generally originated by a particular SMTP client and receive a reciprocal
response from a SMTP server and finally the session is opened and the e
messages are exchanged in a smooth flow. This transaction system consists of
three major commands or reply sequences. These commands are,
·
Mail
command- This command is used to establish and construct a return address. This
is an address established for bounce messages.
·
RCTP
command – This particular command is generated to establish a receiver of the
message. It can be used several times, each for every recipient.
·
DATA
is issued to send message text. It is the main theme of the message. It
comprises of a header and a message body, a blank line segregates both these
parts. In general, sense DATA is a group of organized commands. Each server can
provide either positive or negative reply.
It is implemented to access and
operate mainly over internet port 25. Today after repeated technological
advancement 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 Mail
