MX Health Check

MX Health Overview

The StripDNS MX Health tool is built for fast, practical checks when you need reliable answers without jumping between multiple dashboards. Validate MX setup and mail delivery readiness signals. It is especially useful for mail routing and delivery readiness, whether you are diagnosing outages, validating infrastructure changes, or preparing before a migration. Results are optimized for speed and readability so you can move from detection to action quickly during production incidents. For best outcomes, compare findings over time, cross-check with related DNS and TLS tools, and rerun checks after each config update to confirm changes propagated as expected.

How To Use This Tool

Common Use Cases

  • Validate mail routing readiness quickly.
  • Catch MX misconfiguration before incidents.
  • Audit core DNS mail requirements.

Recommended Steps

  1. Enter a valid domain, hostname, or IP based on the tool input format.
  2. Run the lookup and review key output fields first before deep details.
  3. Repeat after any DNS, network, or infrastructure change to confirm results.

Interpretation Tips

  • Compare results over time instead of relying on a single snapshot.
  • Cross-check with related tools for stronger confidence.
  • Document findings with timestamps during incident handling.
FAQ

Missing MX, invalid target hostnames, wrong priorities, and missing A/AAAA records are common.

Yes. MX handles routing only; authentication requires SPF, DKIM, and DMARC.

Service outage, firewall blocks, TLS misconfig, or sender reputation can still block delivery.

No. MX targets should resolve directly to A/AAAA, not CNAME aliases.

Monitor continuously and after DNS, provider, or certificate changes.
