# SMTP (outbound)

**SMTP** is an acronym for **Simple Mail Transfer Protocol**, and is a communication protocol used for sending and receiving email messages over the Internet.

An **SMTP Transport** is used to connect to a **SMTP** service over the internet or local network, to enable the sending of files to the remote **SMTP** service.

You configure the **SMTP Transport** with the appropriate details to allow you to do this.

The **SMTP Transport** can connect to either clear text **SMTP** services, or **SSL** secured **SMTP** services.

The **SMTP** server settings are configured in **General Setup**.

The details configured on the **SMTP Transport** are necessary to know where to send the email.
