SMTP stands for ________.

The correct answer is Simple Mail Transfer Protocol.

Key Points

• Simple Mail Transfer Protocol:
  • An SMTP (Simple Mail Transfer Protocol) server is an application that's primary purpose is to send, receive, and/or relay outgoing mail between email senders and receivers.
  • SMTP is part of the application layer of the TCP/IP protocol. Using a process called “store and forward,” SMTP moves your email on and across networks. It works closely with something called the Mail Transfer Agent (MTA) to send your communication to the right computer and email inbox.

Important Points

• IMAP (Internet Message Access Protocol) is an email protocol that deals with managing and retrieving email messages from the receiving server.
• Since IMAP deals with message retrieval, you will not be able to use the IMAP protocol to send emails. Instead, IMAP will be used for receiving messages.
• POP stands for Post Office Protocol. And the number three stands for “version 3,” which is the latest version and the most widely used — hence the term “POP3.”
