Email authentication

Give receiving systems a clearer way to verify your email.

Caboodle reviews authorized senders and configures SPF, DKIM, and DMARC around the systems using your domain. We use a staged plan for monitoring and policy changes so legitimate senders are accounted for before enforcement is tightened.

What's included

Account for every system sending as your domain.

The final scope names the deliverables, dependencies, and review points before work begins. The work below provides the starting point for that discussion.
  • Sender inventory. Identify mailbox providers, applications, forms, campaign tools, and other approved sending systems.
  • DNS review. Inspect existing authentication records and establish who can approve and make DNS changes.
  • SPF configuration. Prepare the authorized-sender record while checking the structure and applicable lookup constraints.
  • DKIM configuration. Coordinate signing setup and publish the records supplied by supported sending providers.
  • DMARC monitoring. Configure an agreed initial policy and reporting destination for visibility into authentication results.
  • Message validation. Inspect representative messages for authentication results and the intended domain alignment.
  • Enforcement plan. Recommend staged policy changes based on the observed legitimate senders and approved risk tolerance.
  • Maintenance handoff. Document current records and the process for reviewing new senders and future provider changes.
How this works

Four steps from the first review to handoff.

Phase 1

Identify legitimate senders

Build a domain-level inventory before changing the records used to authorize mail.
Phase 2

Configure and validate

Prepare the provider-specific records and inspect test messages from the agreed sending systems.
Phase 3

Review monitoring evidence

Use the available reports to identify legitimate traffic that needs further configuration.
Phase 4

Advance the policy carefully

Apply approved enforcement changes and document how the domain’s authentication will be maintained.
