Hi,

i created PTR for my mx:
140.155.212.200.IN-ADDR.ARPA

When i done the ask to my DNS server, it answer the correcty name,
ferro.rederecord.com.br. But when i done to any internet server , they
donīt answer me. Filters are not problem because my internal e external
ipīs answer the correct PTR.
Iīll thanks any idea.
