SMTP Full Form

What is the full form of SMTP?

The full form of SMTP is the Simple Mail Transfer Protocol. It is a basic protocol for sending emails via servers between two computers on a TCP / IP network. It is part of the TCP / IP protocol application level, which makes it easy to deliver email messages to one or more recipients over the network. Thus, it has been used whenever an email is being sent to the recipient utilizing email servers from an email client, including Gmail or Outlook Express.

Via a mechanism called the store and forward, SMTP transfers your email around networks. It operates in conjunction with the MTA (Mail Transfer Agent) to deliver the mail to the correct device & email inbox. It determines how an email can travel from the MTA of one device to the MTA of another. The message travels from its origin to its destination in steps, and SMTP does its function at every step.
