This is the third screen of the Connection Wizard.  First, type the name for your incoming server.  If you own the domain name "mysite.com", the name of your incoming mail server would be mail.mysite.com.  In other words, simply add "mail." in front of your domain name.

Second, enter the outgoing mail server. To use the Getaway Web Designs server, enter "smtpout.secureserver.net".  Click "Next" in the screenshot to continue the tutorial.
