SMPT stands for Simple Mail Transfer Protocol, a protocol for sending email messages between servers. Most email systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an email client using an email download protocol (usually either POP3).

In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the incoming mail (POP3) server and the SMTP server when you configure your email application.
