THe issue i am having is that i am trying to create a email server but my emails are rejected due to invalid ptr record.
$TTL 600 @ IN SOA ns1.first-ns.de. postmaster.robot.first-ns.de. ( 2016012407 ; serial 14400 ; refresh 1800 ; retry 604800 ; expire 600 ) ; minimum @ IN NS robotns3.second-ns.com. @ IN NS robotns2.second-ns.de. @ IN NS ns1.first-ns.de. @ IN A 18.104.22.168 dns1 IN A 22.214.171.124 dns2 IN A 126.96.36.199 localhost IN A 127.0.0.1 mail IN A 188.8.131.52 mx1 IN A 184.108.40.206 mx1.littlefeather.net IN A 220.127.116.11 www IN A 18.104.22.168 22.214.171.124.in-addr.arpa 3600 IN PTR mx1.littlefeather.net
the above zone file is from the master dns from hetzner. I copied this to my dns server as well. the reverse for my ip is mx1.littlefeather.net
and my email server hostname is mx1.littlefeather.net.
What is wrong with my dns zone file?
