Reverse DNS (PTR) for your server

Reverse DNS (a PTR record) links your server's IP address back to a name, such as mail.example.com. Mail servers check it: if you send email from your own server without it, a lot of your mail ends up in spam or gets refused.

Because the IP addresses are ours, we set the PTR record for you. You request it in the dashboard.

1. Set the forward record first

Make sure the name already points to your server: an A record from mail.example.com to your server's IPv4 address. Many mail servers only trust a PTR record when both directions match.

2. Request the PTR record

1. Open your server in the dashboard and go to the Networking tab.
2. Next to Reverse DNS (PTR), click Request.
3. Enter the name under Desired hostname, for example mail.example.com, and click Request reverse DNS.

This opens a support ticket for you. If the server will send email, tell us what kind in that ticket: mail from your own application, a mail server for your company, newsletters. We ask everyone this, to keep our IP addresses in good standing with the big mail providers.

We set the record and reply in the ticket. After that it can take a few hours before every resolver sees it. Check it with:

dig -x YOUR_SERVER_IP +short
