I’m on at least 2 blocklists at this point for the crime of not having reverse DNS set up. I don’t know how rDNS works. No amount of reading Wikipedia is helping me understand what I have to do.

  • I have a domain at a registrar which gives me bog standard DNS.
  • I have Apache running on my network.
  • I have PiHole running on my network.

My understanding is that rDNS is not set up at my registrar, but somewhere in my network. What do I do?

Thank you for your time.

    No emails just routing issues.

    Copy pasted but I have routing issues that neither my ISP nor the people who suffer from it can pinpoint. I’m so far down this rabbit hole that I’m assuming my IP got on a blacklist that’s sitting on some random networking infrastructure and I’m just trying to resolve all blacklist issues on the off chance that it works.

          Replied in another part of this thread, but basically those blacklists are specific to SMTP and you can just disregard them. They’re not related to any sort of network/routing issue you’re seeing.
