Live Email Routing Tester & Topology Map Auditor

Email Routing Tools

Analyze your complete mail server topology in real-time. Execute un-cached DoH traces to map Active-Active or Active-Passive failover paths, detect illegal CNAME redirects on MX targets, and verify modern IPv6 routing readiness with absolutely zero simulated data.

Email Routing Tester

Analyze the complete routing path of your emails. We evaluate failover priorities, detect illegal CNAME redirects, and map out modern IPv4 & IPv6 delivery paths.

Why Use Our Email Routing Tester?

Ensure your email traffic flows efficiently without hitting dead ends or infinite loops. We analyze the exact path global mail servers take to reach your infrastructure.

Topology Discovery

Intelligently analyzes priority distributions to determine if your routing architecture is set up for Active-Active Load Balancing or Active-Passive Failover.

CNAME Chain Detection

Actively scans MX targets for illegal CNAME redirections. Pointing an MX record to a CNAME is a critical RFC violation that causes routing loops and lost mail.

IPv6 Route Readiness

Evaluates both IPv4 (A) and IPv6 (AAAA) records across your entire mail cluster to verify if your infrastructure can route modern, next-generation email traffic.

Failover Path Analysis

Ensures that secondary and tertiary backup routes actually exist and resolve correctly, guaranteeing deliverability even if the primary path is disrupted.

Real-Time DoH Tracing

Bypasses stale local caches by utilizing secure DNS over HTTPS to perform live lookups exactly as an external sending MTA (Mail Transfer Agent) would.

Clear Path Visualization

Consolidates complex multi-hop DNS resolutions into a clean, easy-to-read table showing exactly where (to which IPs) each priority level routes traffic.
