MX Lookup

The MX records for a domain will be listed in this test's priority order. Changes to MX Records should take effect immediately because the domain's authoritative name server is the first target of the MX lookup. By selecting Diagnostics, you may establish a connection with the mail server, confirm reverse DNS records, run a quick Open Relay test, and gauge response time performance. Additionally, you can compare every MX record (IP address) to 90 DNS-based blacklists.
