Me and a a colleague discussed this just last week and even considered building something ourselves. Good thing you beat us to it, you seem to have done a marvellous job. The one thing we did some thinking about is how to avoid getting blocked. We run a SaaS and have blocked several hundred domains such as mailinator because of the high rates of fraud. Anyway, good luck!
