Yeah, I do realize that this would be ideal for people. It would be possible to point an mx record at me, and I could add your custom domain. So you could point your app.yourdomain.com MX record to my IP. I would know that based on your api key that requests coming from you should be created with the 'app.yourdomain.com' address and not maskedmail.net. That capability is actually built into how I have it set up now. If you are interested I would be happy to talk more about how we could get that set up. Thanks for the feedback
