The SMTP characters stands for Simple Mail Transfer Protocol, which is a protocol used to send messages between servers. Most of the email sending systems over the Internet use SMTP to route messages from one server to another. Then messages can be received by an email client using one of the POP or IMAP protocols. In addition, SMTP is generally used to send a message from a mail client to a mail server. When you set your email to your mail client is necessary to enter the information for your POP / IMAP server, and the SMTP server.
