Let me clarify a few things between the email settings from adminui and the email settings from the Email service.
"This Email service is independent"
You are correct. The Email service in Workbench is independent from the email settings in adminui. The email service in adminui is used for the different notifications in Process Management.
The Email service in Workbench is a generic email service to send email.
"The "Use Configuration Options" uses the configuration options of the "EmailService" service and not the configuration from the adminui"
This is not true. The Email service is independent from the email settings in adminui and doesn't have access to its settings.
You can configure the Email service two different ways. One is when you add the service into your process. That confi way you configure a particular instance of the email service (for that process only).
The other way is to configure the settings on the component itself (from the component view). That way every time you use the email service you can use the settings defined at the component level by selecting the checkbox.
Now that being said I had tried to use a Gmail account with the Email service with no luck. I beleive there was a bug in the component. You could follow up with support on this.
