I am a complete beginner, so bear with me. I have successfully created a droplet, and installed my wordpress there. I am also using cloudflare for my CDN. Unfortunately I couldn’t get email to work. (Im using third party service for email aka google apps for work) The email sent from my wordpress is marked as spam. Upon further conversation with google support, I was told that this is because my PTR/reverse DNS has not been set up. (as listed on this website: http://www.intodns.com/paperdorable.com)
I have looked at a few tutorials, but they all involved setting up FQDN, to my understanding I need to setup something like mail.mydomain.com for FQDN. Is mydomain.com not considered an FQDN?
for information, My domain/URL is paperdorable.com my droplet is called paperdorable.com
when i do #hostname, i received --> paperdorable.com and when I do # hostname -f, I received --> paperdorable.com
Can anyone guide me on how to set PTR/reverse DNS so that my emails are no longer marked as SPAM?
