Simple Mail Transfer Protocol (SMTP) Video Lecture - Computer Science Engineering (CSE)

hi there in this video you'll learn what
SMTP is and how it works
SMTP stands for Simple Mail Transfer
Protocol while pop and IMAP are
protocols that allow you to retrieve
email from a mail server SMTP is the
protocol that allows you to send email
to a mail server specifically the SMTP
protocol is used to send email from an
email client to your email providers
mail server and to send email between
two mail servers on the Internet when
you use a free email provider your email
address uses their domain name and in
turn they allow you to use their email
servers if you use their webmail site to
read and send email they handle the
email server settings that direct your
incoming and outgoing emails however if
you want to use a local email client
like MS outlook Apple Mail or Mozilla
Thunderbird you'll need to enter your
email providers incoming and outgoing
mail server settings when you set up
your client the incoming server setting
tells the email client where it can
retrieve your email from and the
outgoing mail server setting tells the
email client where it can send your
email to the outgoing server setting is
also known as the SMTP server setting
let's focus on the send mail process and
roll SMTP servers play in it meet Maggie
her email address is Maggie at yahoo.com
though Maggie is using Yahoo as her free
email service provider she likes to use
the email client Microsoft Outlook for
composing reading and sending her email
to make sure outlook can communicate
with Yahoo's mail servers she entered
Yahoo's email server settings when she
configured MS outlook
Maggie writes an email to her friend Rob
using MS outlook when she clicks send MS
outlook sends Rob's email address her
email address and the body of the
message to Yahoo's SMTP server upon
receipt the Yahoo SMTP server breaks
Rob's email address into two parts the
recipient ID or what displays in front
of the at sign and the domain name
gmail.com or what displays after the
sign the Yahoo SMTP server then goes out
to the Internet and through a series of
server conversations locates the SMTP
server for the domain name gmail.com the
Yahoo SMTP server passes Maggie's email
to Gmail's SMTP server once Maggie's
email arrives at Gmail's SMTP server it
remains there until Rob logs into his
gmail account and retrieves the email
let's recap SMTP is the protocol that
allows you to send emails from an email
client to a mail server once on a
senders outgoing email server SMTP uses
the domain name in an email address to
locate the recipients email server where
the email remains until the recipient
receives it
