    Hi everyone, I've tried Configuring Reverse DNS for BIND and Configure Reverse DNS in WHM to set up my reverse DNS. When I do hostname, I get
    Code:
    # host 12.345.67.890
    890.67.345.12.in-addr.arpa domain name pointer mydomain.com.890.67.345.12.in-addr.arpa.
    
    So when I try to send an email, it gets sent back because RDNS fails. My file in /var/named is 67.345.12.in-addr.arpa.

    My file:
    Code:
    67.345.12.in-addr.arpa. 86400   IN      SOA     ns60.mydomain.net.    support.mydomain.com. (
                                                    2014021205 ;Serial Number
                                                    86400 ;refresh
                                                    7200 ;retry
                                                    3600000 ;expire
                                                    86400 ;minimum
            )
    67.345.12.in-addr.arpa. IN      NS      ns60.mydomain.net.
    67.345.12.in-addr.arpa. IN      NS      ns50.mydomain.net.
    890     IN      PTR     mydomain.com.
    890     IN      PTR     www.mydomain.com.

    IP address space, just like domains, is allocated to specific nameservers. So make sure your nameservers are authoritative for the IP space you're trying to create PTRs for.

    Anywho, a hostname like "mydomain.com.890.67.345.12.in-addr.arpa." indicates the absence of a period after the hostname. It's in the zone you pasted, but not sure if that zone is the one that's actually loaded.

    Hello :)

    Please ensure that your data center/network provider has delegated the ability to setup your own PTR record on the server. Some data centers restrict this ability and must setup the record for you.

    Thank you.
