Generate production-ready DNS records for professional email hosting. Copy-paste into your DNS provider.
SPF (Sender Policy Framework) is a DNS TXT record that specifies which mail servers are authorized to send email on behalf of your domain. It prevents spoofing and improves deliverability.
DMARC tells receiving mail servers what to do when SPF or DKIM authentication fails. Policies include none (monitor), quarantine, or reject.
Autodiscover (Outlook) and Autoconfig (Thunderbird) CNAME records let email clients auto-configure server settings. Optional but highly recommended.
Start with none to monitor, then move to quarantine, and finally reject for maximum protection once you confirm legitimate mail passes SPF/DKIM.
