Okay people, I have something for you. Nothing major, but curious...We have reverse DNS on our mail servers setup with our ISP, which is logical. Our MX records are hosted on namesdirect.com where we have an account for some other DNS purposes.My Question is, should our MX records also be hosted by our ISP or does it even matter where they are?And second, there are duplicate A/PTR records for our mailservers on namesdirect. Could this cause a DNS loop out on the internet and interrupt proper mail flow?Did I confuse anyone? If you need me to be more clear just say so.Thanks
