Request reverse DNS (PTR) for your mail server

Reverse DNS (a PTR record) maps your server's IP address back to a hostname. Mail providers check it — without a matching PTR, your email is far more likely to be rejected or marked as spam.

Why you cannot set it yourself

A PTR record lives on the network that owns the IP address, not in your domain's DNS. That means it has to be set on the hosting side.

Steps

1. Finish your mail setup so your mail hostname is defined.
2. Open the Mail section and use the request PTR action.
3. The request goes to the SoftServer team, who set the reverse DNS for your server's IP to match your mail hostname.

After it is set

Once the PTR matches your mail hostname and your SPF, DKIM and DMARC records are correct, your server has the full set of signals that mail providers look for.
