I use Zeroshell as my DNS server for several websites and for the first time i had to configure the PTR record for a mail server (all the sites use Google Apps mail but this one). Where do i do this for this specific domain?
mxtoolbox.com outputs the following message (i had to truncate the real address):
“ptr requires an IP Address and mail.example.com is not a valid IP.”
i know that PTR record is something like 220.127.116.11.in-addr.arpa and point it to mail.example.com, but where do i configure it in ZS?
PS – The mail server is already up and running sending and receiving mails but i think that for it to be fully standards compliant it has to have a reverse lookup.
