List business senders
Include employee mail, contact forms, receipts, account messages, newsletters, help-desk tools, and legacy integrations.
Collect provider requirements
Record the domain identities, DNS records, and authentication setup each provider documents. Keep tokens and secret credentials out of shared examples.
Inspect representative messages
Use messages you are authorized to examine to compare visible From identity with reported SPF, DKIM, and alignment results.
Plan monitored changes
Resolve unknown senders and setup gaps before stronger enforcement. Document expected results and review actual reports and delivery.
Worked scenario
See the plan in practice.
An order receipt and a newsletter may use different services. Both need to be represented before a domain-wide policy is changed.
Review your result
Your acceptance checklist
Senders named- Identities checked
- Monitoring assigned
Use these checks to identify gaps in your verified sending-service inventory. Assign an owner to any unresolved item before the next dependent step.
The terms behind the task
- SPFSender Policy Framework lets a domain publish which senders are authorized for the envelope-from or HELO identity used in mail transport.
- DKIMDomainKeys Identified Mail attaches a domain-associated cryptographic signature that receiving systems can verify using DNS.
- DMARCAn email authentication policy and reporting mechanism that relates SPF or DKIM authentication to the visible From domain through alignment.
