Could you explain what the issue is that you’re having?

Those IP addresses aren’t used for emails at all - they’re what Cloudflare will fetch your origin from. https://www.cloudflare.com/ips/

Cloudflare only offers email forwarding - if that’s what you’re referring to, the IP ranges it uses are documented here: https://developers.cloudflare.com/email-routing/postmaster/#outbound-hostnames
