Hello! I have 1 droplet have 3 domain. I need that for each domain was registered your rDNS. So there must be three record rDNS for each domain: 51.172.185.146.in-addr.arpa name = site1.com 51.172.185.146.in-addr.arpa name = site2.com 51.172.185.146.in-addr.arpa name = site3.com
How do I add these rDNS for each domain?
Make 3 droplets too expensive. Support DO in fact refused to solve my problem.
In the result I am unable to use mail. I.e. it does not reach the addressee, and blocked because of the error: “host mx1.example.com[999.888.777.666] said: 550 X-Host Lookup Failed: Reverse DNS lookup failed for 146.185.172.51 (failed)”
I need your help.

Kamal, not correct for your last statement. you can have as many PTR records for an IP as your heart desires. It is functionally and technically correct.
In your <a href=“https://cloud.digitalocean.com/droplets”>DigitalOcean Control Panel</a>, make sure that the hostname you’ve assigned to your droplet is a fully qualified domain name (FQDN).
Yes FQDN she FQDN… Only messages from mailboxes do not reach the required destination.
