When I test my domain dns in (after adding spf record) I found the following error in the "Reverse MX A records (PTR)" section Reverse MX A records (PTR) ERROR: No reverse DNS (PTR) entries. The problem MX records are: -> no reverse (PTR) detected . You should contact your ISP and ask him to add a PTR record for your ips What is the solution for this? Thanks for help in advance.

Your droplet's hostname is 'as7'. You have to rename to using our control panel.
I have renamed the droplet to , now do I have to change the A records in DNS?

No, wait until the PTR record propagates and run that check again.
  • I encountered this exact issue and once I renamed droplet from



    and did a reboot all was well immediately as per checker site mentioned above :

    thank you very much

Have your got your hostname set as a valid hostname for you Droplet with IP :

A PTR is created for the IP automatically with the hostname of the droplet.
but my IP address is differenct that provided in by the value and I have correct hostname .
I have another droplet(having the different IP) and for the same is showing the same result as mentioned above.

Thanks for further help. @ash
The IP address,, does not belong to DigitalOcean. Unfortunately, in this case, there is nothing we can do on our end. Contact your ISP (the one that owns and ask them to set up a PTR record for you.
I did not understand @kamal how can an ISP set my PTR, when a dns is managed by DO.
I use various different ISP so whom should I ask ?
The PTR record is bound to an IP address and not to a domain name. appears to be owned by Pentastar Services -- try contacting them.
I still did not get it :( . I am in India and never heard of Pentastar Services. Do you want me to contact my domain registrar and ask them to do this? else I have no idea what to do ........... I am totally confused !!!!

Is your IP address or
My IP is neither of the above @Pablo it is very different from the above!!!
Are you trying to manage your own e-mail server or are you outsourcing your email to a third-party provider?

I am managing my own email server.

What's the domain name?
Sorry, my bad. was a mistake on my part -- you don't have anything to do with that IP address. Your droplet's hostname must be a FQDN, e.g.
Make sure you change it in our control panel so that the PTR record is updated.
myhost name is a FQDN I have checked in putty with this command and it shows
I have only one host name whcih is and it was taken from the DO while creating a droplet through which I made the FQDN. I have checked these things several times.
Please let me know if I am missing anything. I have checked my DNS and their records and all IP are same as the droplet IP.
Thanks a lot @kamal. now is not showing any errors.
