When I test my domain dns in intodns.com (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: 158.146.241.192.in-addr.arpa -> 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 as7.domainname.com using our control panel.
I have renamed the droplet to as7.domainname.com , now do I have to change the A records in DNS?

Thanks
No, wait until the PTR record propagates and run that intodns.com check again.
Have your got your hostname set as a valid hostname for you Droplet with IP : 158.146.241.192?

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 intodns.com value 158.146.241.192 and I have correct hostname .
I have another droplet(having the different IP) and for the same intodns.com is showing the same result as mentioned above.

Thanks for further help. @ash
The IP address, 158.146.241.192, 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 158.146.241.192) 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. 158.146.241.192 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 !!!!
@hypertextsol,

Is your IP address 158.146.241.192 or 192.241.146.158?
