Zero Email Domain

Automatically create "reject all" SPF, DKIM, and DMARC DNS records in domains that contain no MX records.

This is an quick concept that I made using PowerShell and the Cloudflare API so I could quickly achieve this task for the 60+ domains that I was responsible for.

Requirements

• A Cloudflare account
• At least one domain that uses Cloudflare managed DNS
• A Cloudflare API token that has permissions to view the zone[s] and edit DNS records in the zone[s]
• PowerShell

To Do

• Create documentation.
• Better handling of API keys.
• Improve API usage and add paging.
