Email authentication maintenance note
Email DNS changes should be handled like a launch task, not a quick copy-and-paste job. Before changing SPF, DKIM, DMARC, MX, or SMTP settings, record the current DNS values, confirm who sends mail for the domain, and keep a rollback note in case forms, invoices, password resets, or customer replies stop flowing.
Safe verification checklist
- Confirm there is only one SPF TXT record for the domain.
- Check that every active sender is included before tightening SPF or DMARC policy.
- Verify DKIM signing from the actual mail provider, not only that a DNS selector exists.
- Start DMARC in monitoring mode when you are not sure all senders are aligned.
- Send test messages to multiple mailbox providers and review headers before declaring the change finished.
