SMTP stands for Simple Mail Transfer Protocol. It handles the sending of emails.

The ability to support email services includes two critical functions: SMTP and POP3. Together, they allow the user to send outgoing mail and retrieve incoming mail, respectively.

• It verifies that anyone attempting to send outgoing email through the SMTP server is allowed to do so
• It sends the outgoing mail and if undeliverable, sends the message back to the sender

If you are using a email client, you will need to configure the SMTP server setting so that you can send outgoing emails.
