First you need to install the SMTP Mailer Module in order to use it.

To do so login to the Dolphin Pro Administration Dashboard and go to:
Modules
-Add & Manage

Find the "Not Installed Modules" section in the center of the page. Scroll down until you find the SMTP Mailer. Check the box next to it. Then, scroll down a little more and click the "Install" button.

Once it is installed you will find it in the "Modules" menu section on the left hand column of the Administration Dashboard.

Click on the SMTP Mailer Module to configure it for the particular email address you intend to use.

For Gmail you can use either port 465/SSL or port 587/TLS.
