MX Lookup

Look up MX (mail exchange) records for a domain.

When to use this tool

MX Lookup retrieves the mail exchange records for a domain, showing which servers handle its email delivery. This is critical when configuring email services, troubleshooting email delivery problems, or verifying that SPF and DKIM records align with the mail servers. It displays the priority and hostname of each mail server.

How to use

Enter the domain name whose mail servers you want to check. Click the "Lookup" button to query the DNS for MX records. Results will display each mail server's priority and hostname, sorted by priority.
