 * Hi. I have a client using GoDaddy and the confirmation emails from forms don’t
   always show up. I’m trying your plugin, but get “Incorrect Authentication Data”
   when a test is sent during setup. During the setup wizard, what should I be putting
   in the Authentication fields “How will you prove your identity to the MSA”?
 * Thanks!

 * If you are connecting to the GoDaddy SMTP server (relay-hosting.secureserver.
   net), you must have a GoDaddy email account and it’s those credentials you enter.
 * if you are connecting via the Gmail API, then it’s your Google OAuth 2.0 credentials
   you enter.

 * I deleted the settings, cleared the cache and tried again. I am using a Go Daddy
   email (info@thatdomain.com) and I’ve added the email and password on the Authentication
   screen. I’m still getting: incorrect authentication data and a test email isn’t
   received.
 * Any ideas?

 * You could ask GoDaddy why it’s not working, but in my experience their tech support
   may not help you satisfactorily. Instead you may try switching to the **localhost**
   SMTP server and using **no** authentication.
