Advanced RFC Compliance Validation
Don't just check if records exist. We deeply parse your SPF to ensure it doesn't exceed the strict 10-lookup limit, audit your DMARC syntax, and verify your MX records don't point to illegal CNAMEs.
Real-Time SPF Limit & MX CNAME Diagnostics
Guarantee your domain's structural perfection for maximum email deliverability. We execute direct, encrypted DNS over HTTPS (DoH) queries to deeply parse your SPF record against the strict 10-lookup limit, instantly audit DMARC syntax for active anti-spoofing enforcement, and actively resolve MX targets to detect illegal CNAME violations (RFC 2181). Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend catches hidden compliance errors to ensure your infrastructure is perfectly validated.
Don't just check if records exist. We deeply parse your SPF to ensure it doesn't exceed the strict 10-lookup limit, audit your DMARC syntax, and verify your MX records don't point to illegal CNAMEs.
Having DNS records isn't enough; they must be structurally perfect. We catch hidden RFC violations that cause silent email failures, ensuring your domain is truly ready to send mail.
