E-mail Protocols are set of rules that help the client to properly transmit the information to or from the mail server. Here in this tutorial, we will discuss various protocols such as SMTP, POP, and IMAP.
SMPTP
SMTP stands for Simple Mail Transfer Protocol. It was first proposed in 1982. It is a standard protocol used for sending e-mail efficiently and reliably over the internet.
Key Points:
• SMTP is application level protocol.
• SMTP is connection oriented protocol.
• SMTP is text based protocol.
• It handles exchange of messages between e-mail servers over TCP/IP network.
• Apart from transferring e-mail, SMPT also provides notification regarding incoming mail.
• When you send e-mail, your e-mail client sends it to your e-mail server which further contacts the recipient mail server using SMTP client.
• These SMTP commands specify the sender’s and receiver’s e-mail address, along with the message to be send.
• The exchange of commands between servers is carried out without intervention of any user.
• In case, message cannot be delivered, an error report is sent to the sender which makes SMTP a reliable protocol.
