  • It had our RBL checks confused, that's for sure.

  • RBL servers are expected to return a response in 127.0.0.0/8 range for a positive response.
    If the domain is resolving to parking page, the response is not in 127.0.0.0/8.
    Why don't the RBL querier reject such invalid responses?

    Sloppy design, sloppy code…
