I have an Ubuntu 18.04 droplet being used as a web host for a shared hosting setup. I need to set up a Reverse DNS record for the Web Host as outgoing emails from the hosted sites are being rejected by recipients as the server does not have Reverse DNS setup.
Unfortunately, I did not name the droplet with a FQDN, just a descriptive name: should I do this? If so, I cannot see how to name/rename the Droplet in the Digital Ocean Control Panel.
Also the DNS for the Host Servers domain is not located in Digital Ocean, but in a third party DNS hosting service, and I don’t really want to move it.
So, how do I set up a Reverse DNS record under these circumstances? Thanks!

The Reverse DNS is configured automatically from our end based on the droplet’s hostname.
To rename your droplet via the control panel, do the following:
Login to the Digital Ocean Control Panel
Make sure you also edit your droplet’s hostname internally as well. Update /etc/hostname and /etc/hosts and reboot.
The PTR should be automatically adjusted in few hours due to DNS cache. If this is still not working after several hours, you can contact our support team as well.
Let us know how it goes.
