I wanted to set rDNS for AWS for my mail server. I have created glue records, therefore my nameservers are like ns1.mydomain.com & ns2.mydomain.com. Note: My domain registrar is AWS and may mailserver will take care of DNS.
So, I followed this guide https://aws.amazon.com/premiumsupport/knowledge-center/route-53-reverse-dns/, but I am little confused.
Suppose my IP is 18.104.22.168.
I created a new hosted zone with the name 70.60.50.in-addr.arpa
I created a record set and added a PTR record for the SMTP server as follows Name field : 22.214.171.124.in-addr.arpa Value field: mail.mydomain.com
Now, in this hosted zone, I have 2 extra records. In type NS, I replaced AWS nameservers to my nameservers ns1.mydomain.com & ns2.mydomain.com. I don't know what to do with SOA. I would be thankful for any help.
