What to fix

  1. Warning

    Reverse DNS is not delegated for 2a00:12e8:f123::/48, so its addresses have no PTR records.

    Mail receivers look up the PTR of the sending address and reject or spam-score mail without one; traceroutes and logs show bare numbers.

    Fix: Create the reverse zones (domain objects for in-addr.arpa or ip6.arpa) at your RIR, pointing at your nameservers, or ask your provider to set PTR records.
