Reverse dns setup

[ashok]

Hi,
    I have installed sentora in
    Domain-panel.360shutters.in
    ipv4 is 104.238.182.138 and ipv6 is 2001:19f0:ac00:8e2::
    I have added 3 more domains in the same server.
    My current revers dns value for  is 138.182.238.104.in-addr.arpa name = panel.360shutters.in.
    Do i need to configure it for ipv6 also? If so how do I do it?
    All my e-mail are marked as spam and gets an error like"Delivered to internal network by a host    with no rDNS"

  How do I setup reverse DNS properly?

Thanks in advance

The Reverse DNS is usually setup on the IP owner.
You should request your VPS hosting provider to setup the reverse DNS correctly for your domain.
You can also set a PTR record (Read: http://help.dnsmadeeasy.com/managed-dns/...tr-record/) however I'm not sure if it is enough.
