This isn't some new way to get Gmail on your domain, but it's easier and faster to set up with the browser extension. In wizard mode, you first set up all mail forwarding from your domain (wildcard *@yourdomain.com) to your Gmail address. A free plan from the EForw email forwarding service is used. Then it is set up to send mail from Google's servers via the "Send As" feature. So outgoing emails from your domain will have a good sender reputation. I will be happy to feedback/suggestions for improvement.
