No rDNS. Ip blacklisted

Hey, I have been blacklisted on ip that points to Cloudflare.
You can check here.

How can I fix it?

You’d have to contact spfbl to delist it. It’s an unreasonable test for a domain, considering very few domains have IP addresses that rDNS to that domain. It’s especially unreasonable to use such a test for anti-spam verification.

Is this actually causing a problem with mail delivery from your domain?
