How to associate multiple domains to a droplet for PTR?

It is a simple feature. A lot of people have that use case (mostly using several email domains with one mail server). I saw some on Twitter quitting DO because that was impossible. Is it still unavailable after all this time?

Hello,
As per this comment here, you can set the Droplet’s hostname (which would update the PTR record along with it) to e.g. mail.yourdomain.com where yourdomain.com is one of the domains on that droplet, and then add an A record for mail.yourdomain.com that points to your droplet.
This way it will be a valid PTR <=> FQDN setup and it will work fine for all of the domains on that Droplet.
As a side note, I could also suggest checking this discussion here on why adding multiple PTR records is not recommended:
