How to configure Reverse DNS for multiple virtual servers in virtualmin
I have read most of what i can find but cant find an answer.
Essentially I have a droplet with a domain that I dont use.
In that droplet I have Virtualmin and have three servers, each with emails.
They are having their mail blocked because there is no reverse DNS set up for the domains.
I have read that Digital Ocean sets up the reverse DNS automatically for the domain associated with it. However, there appears no way to set the reverse DNS for the sub servers.
How can i do that?
Just to make it clearer, I have a domain masterdomain.com that I set my droplet up on.
I have customer1.com on a virtual server setup in VirtualMin and his emails are being blocked because the domain lacks a reverse DNS PTR record or whatever you call it.
