Manage sources

You can approve sources to send emails from your domain:

  • If you mark a source as Approved, Cloudflare will include the IP ranges for that source in your SPF record and flatten as needed.
  • If you mark a source as Unapproved, Cloudflare it will delete the IP ranges for that source from your SPF record.

When you feel confident that you have covered every source that is legitimately sending emails from your domain, Cloudflare can help you set your DMARC policy to quarantine or reject, so that potential targets stop receiving emails from impersonators.

To approve or disallow a third party source:

  1. Log in to the Cloudflare dashboard, and select your account and domain.
  2. Select Email > DMARC Management.
  3. Go to Top 10 sources > View all.
  4. Select the Approved or Unapproved tabs depending on whether you want to check for sources that are approved or unapproved to send emails from your domain.
  5. Find the third party you want to change, and select the three dots next to it.
  6. Select Mark as approved or Mark as unapproved.
  7. Confirm your choice.
