MX Record Lookup
Look up MX records sorted by priority. Identifies your email provider and checks that each mail server resolves to a valid IP address.
What are MX records?
MX (Mail Exchange) records tell the internet which servers handle email for your domain. Each MX record has a priority value — lower numbers have higher priority. When someone sends email to your domain, their server looks up your MX records and tries the lowest-priority server first.
If an MX record doesn't resolve to an IP address, email delivery to that server will fail. Having multiple MX records with different priorities provides redundancy.
