Hi, Al. Thanks for the suggestions. We've actually got some of these in planning or development already, but the point on your blog is well taken that we will probably need to start guiding customers away from using third-party domains. I wish I had understood that aspect of DMARC earlier -- I had been focusing entirely on helping customers authenticate their own domains.
I still don't have a good plan for the customers who have already signed up with third-party domains and are suddenly seeing a lot of bounces.
