Set up reverse DNS

POST {{baseUrl}}/whitelabel/ips

This endpoint allows you to set up reverse DNS.

When setting up reverse DNS, use the same subdomain that you used when you authenticated your domain.

Reverse DNS consists of a subdomain and domain that will be used to generate a reverse DNS record for a given IP. Once SendGrid has verified that the appropriate A record for the IP has been created, the appropriate reverse DNS record for the IP is generated.
