I only know you'd be better off with reliable resolvers you can control when running an MX and rely on reverse DNS to be OK and use DNS blocklists. We use only local DNS resolvers, and do not have problems many others have. It's not difficult to set up, so there's no point rely on a third party for such basic and important service. Mikael
