MX Record Lookup
MX (Mail Exchange) records tell other mail servers where to deliver email for your domain. Missing, misconfigured, or unresolvable MX records mean incoming email will bounce. Enter a domain to inspect its MX configuration.
What does this check?
- Whether MX records exist and are correctly published
- Priority values across multiple mail server entries
- Whether each MX hostname resolves to a valid IP address
- Missing or duplicate MX entries that could affect delivery
- Common mail provider identification (Google, Microsoft, etc.)
