In order to have one’s emails processed correctly, a valid reverse DNS entry is needed. Supposedly, a reverse DNS entry is automatically created using the name that is given to a droplet, and when you change it, the new name is associated with the IP address. In doing an “nslookup” on the IP address for my droplet, the following message is displayed:
** server can’t find 000.000.000.000.in-addr.arpa.: NXDOMAIN
I do have my own DNS servers where foreward DNS for the droplet resides. What is the correct way to have a valid reverse DNS entry created?
