MX Records Tools

Run a live verification of your mail servers. Test SMTP readiness on Port 25, validate the 220 greeting banner, and authenticate SPF and DMARC in one robust test.

Visualize your email routing with an intuitive tiered flowchart. Analyze MX priority logic, detect round-robin load balancing, and perform priority gap analysis.

Automate your email infrastructure. Auto-discover your DNS provider and web IP to instantly generate deployment-ready BIND zone files and Terraform HCL scripts.

Audit your entire email ecosystem for modern security standards. Validate MTA-STS enforcement, check TLS-RPT monitoring, audit BIMI readiness, and ensure encrypted inbound mail.

Verify your global MX record rollout. Query 5 backbone resolvers concurrently, calculate exact propagation percentages, detect majority consensus, and match expected values.

Monitor your MX configurations in real-time. Visualize DNS latency, track true Port 25 uptime, detect instant configuration changes, and track email server health with a live NOC dashboard.

Troubleshoot bounced emails with our automated SysAdmin diagnostic engine. Pinpoint exact misconfigurations causing delivery failures and get actionable, step-by-step fixes for MX, SPF, and SMTP errors.

Query Google, Cloudflare, and Quad9 concurrently to verify real-time DNS propagation. Audit all major record types, detect cached mismatches, and inspect raw DoH responses instantly.

Perform the ultimate health check on your email infrastructure. Calculate your overall MX health score by combining DNS validation, live SMTP port tests, RBL blacklist checks, and SPF/DMARC audits.

Perform a comprehensive security sweep of your MX records. Concurrently sweep mail ports (25, 465, 587), detect firewalls, and audit BIMI and DMARC configurations for optimal security.

Perform a deep security and reputation inspection on your MX records. Grab SMTP greeting banners, identify server software, and check underlying IPs against global RBL blacklists.

Ensure your fallback mail servers are genuinely redundant. Detect subnet collisions, verify physical network separation, and audit your email disaster recovery architecture.

Audit your email failover architecture. Detect fake failovers with shared IPs, analyze backup server hierarchy, and test active port connectivity for enterprise redundancy.

Perform live SMTP tests on your MX records. Simulate physical TCP connections on Port 25, verify server reachability, bypass firewalls, and get an actionable availability grade.

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.

Query global DNS resolvers like Google and Cloudflare to fetch live MX records. Check worldwide propagation, resolve host IPs, and inspect raw JSON developer views.

Perform deep validation of your MX records. Verify RFC compliance, resolve host IPs, detect Null MX configurations, and analyze priority load balancing.

Auto-discover your underlying infrastructure and generate deployment-ready MX records. Instantly build complete BIND zone files and Terraform HCL scripts.

Perform a real-time MX record lookup. Check mail server routing, inspect priority and TTL insights, and troubleshoot email delivery issues instantly online.
