What is SMTP and why do you need it?

Simple Mail Transfer Protocol or SMTP is the protocol used for sending emails over the internet. Your email client uses SMTP to send a message to a mail server, which then uses SMTP to relay the message to the correct receiving mail server.

In essence, SMTP is a set of commands that authenticates and directs the transfer of electronic mail. When configuring your email program, you will typically need to set the SMTP server to your local ISP's SMTP settings.
