What if I host several domain names on a droplet? How do I set up the reverse DNS for all of my domains, so the email sent from whichever domain won't be rejected?
Reverse DNS is set up automatically for your droplets based on the name you give them. As long as you name (or rename) your droplet to a domain or subdomain name the record will be created automatically.
