MXToolbox, based in Austin, TX, specializes in email delivery problem solving by providing a comprehensive MX Lookup service. This tool lists MX records for a domain in priority order, ensuring that users can see immediate changes made to their MX records through direct queries to the domain's authoritative name server.

In addition to MX lookups, MXToolbox offers diagnostics that connect to mail servers to verify reverse DNS records, perform Open Relay checks, and measure response time performance. Users can also check each MX record's IP address against numerous DNS-based blacklists, commonly referred to as RBLs or DNSBLs.
