Re: Test your domain for errors
This post is recommending the use of MXToolbox, which is a web-based service used to test and diagnose domain and email infrastructure issues such as DNS records, MX (mail exchange) configuration, and IPv6 settings. The idea is to help users verify that their domain is properly configured and functioning correctly, especially for email delivery and server reliability, by running automated checks that can identify common setup errors or misconfigurations.
