Backend-Powered MX Record Analyzer & Configuration Audit

MX Records Tools

Run a deep, backend-powered analysis of your MX records. Audit SPF and DMARC policies, verify RFC 5321 compliance, bypass local caches, and receive an actionable health score.

Ready to Analyze

Enter a domain to perform a deep, backend-powered analysis of its MX records. We will check for RFC violations, priority errors, and verify IP resolution.

Why Use MX Record Analyzer?

Our backend-powered analyzer runs deep configuration checks on your mail servers. Verify RFC compliance, detect missing SPF and DMARC policies, and prevent your emails from bouncing.

Deep IP Resolution

We perform backend DNS lookups to ensure that the target hostnames of your MX records actually resolve to valid IPv4 addresses (A Records) to guarantee delivery.

RFC Compliance Check

Our C# backend engine detects common misconfigurations, such as pointing an MX record directly to an IP address (which violates RFC 5321) or pointing to local hosts.

SPF & DMARC Audit

Automatically checks your domain's TXT records to confirm the presence of valid Sender Policy Framework (SPF) and Domain-based Message Authentication (DMARC) policies.

Priority & Balancing Analysis

Analyzes your priority routing logic. It detects if you have duplicate priorities (Round-robin load balancing) or if you lack a backup server.

Health Scoring System

Calculates a comprehensive Health Score from 0 to 100 based on redundancy, resolvability, and formatting accuracy to give you a clear, actionable grade.

Backend API Integration

Unlike simple browser lookups, this tool communicates with a robust API backend, bypassing local caches and browser restrictions for maximum accuracy.
