MX Lookup Agent – Mail Exchange Record Checker

MX Lookup Agent is a fast and reliable online tool that allows you to scan and display MX (Mail Exchange) records for any domain name. MX records define which mail servers are responsible for receiving emails for a domain, making them a critical part of email delivery and DNS configuration.
MX Lookup Agent works directly in the browser and retrieves real-time MX record information by querying DNS servers. It helps website owners, email administrators, developers, and IT professionals verify email routing, diagnose delivery issues, and confirm mail server setup without any login or software installation.

How MX Lookup Agent Works

To check MX records, simply enter a domain name into the tool and start the lookup. The tool fetches the mail exchange records associated with the domain and displays the mail servers along with their priority values.
Checking MX records is especially important when setting up email services, migrating email providers, or troubleshooting problems where emails are not being delivered correctly. Incorrect or missing MX records can cause emails to bounce or fail silently, which can affect business communication and user trust.

Common Use Cases of MX Lookup Agent

MX Lookup Agent is commonly used for:
  • Verifying mail server configuration for a domain
  • Troubleshooting email delivery problems
  • Checking MX record priority and redundancy
  • Validating DNS changes after email migration
  • Ensuring proper email routing for business domains
  • Identifying potential DNS or mail server misconfigurations
