NO reverse RTR detected?

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.

No, wait until the PTR record propagates and run that check again.

Your droplet’s hostname is ‘as7’. You have to rename to using our control panel.
