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 helps prevent email spoofing and improves deliverability.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is a DNS TXT record that tells receiving mail servers what to do when SPF or DKIM authentication fails. Policies include none (monitor), quarantine, or reject.
Autodiscover (for Outlook) and Autoconfig (for Thunderbird) CNAME records allow email clients to automatically configure themselves with the correct server settings when a user adds their email account. They are optional but highly recommended.
Start with “none” to monitor authentication results without affecting delivery. Once you confirm legitimate email passes SPF/DKIM, move to “quarantine” (recommended) and eventually “reject” for maximum protection.
