ABOUT THIS TOOL
What the MX Health Check reviews
MX records tell sending systems which servers accept email for a domain and in what priority order. The MX Health Check inspects the published exchangers, resolves their addresses and reviews basic reverse-DNS signals that can help identify routing mistakes or incomplete mail-server configuration.
