problems with reverse dns and ptr records

[raystrach]

i could never be described as a professional server administrator, but i have managed to get my server working quite well over the past few months using cpanel and whm.

however the one thing that i cannot seem to solve is getting the right ptr records for the domains on the server. i really need this to ensure that email sent from the server reliably reaches its destination.

at present i run just a single cpanel account and join each domain as an addon domain to the primary domain. a zone record is created for each.

for example, at the domain, smartspacehq.com i have set the ptr records for the purpose of reverse dns at:

169.93.204.in-addr.arpa. 14400 in PTR smartspacehq.com

i also have a separate zone files for 169.93.204.in-addr.arpa. and 167.93.204.in-addr.arpa. (which i am not even sure that i need) these are the ips associated with this account (one is a static ip- 169.93.204 and the other a dynamic ip)

these records are in the whm panel.

testing reveals that this has not worked. can anyone advise where i am going wrong. any help would be greatly appreciated as i have searched for hours to try to rectify this, without success.

cheers

Hello,

If you do not control the IP delegation, and most servers do not have control of the IP as the IP provider does, then you cannot setup a PTR record for rDNS in WHM and have it work. If you did set this up in WHM, then you should remove the PTR record you'd setup and let your host do it if they have the IP delegation.

The only way these zones can be setup and work will be when the IP provider delegates control of the IP to the server, which again is rare and only happens if your IP provider does confirm they've delegated the control to your machine.
