FAQ
Does this perform a real DNS lookup?
Not yet — this preview renders an honestly-labeled offline reference for a couple of bundled example domains, and a clearly-marked placeholder layout for anything else. It does not send a live DNS query.
What are MX records, briefly?
MX (Mail Exchange) records tell the internet which mail servers are responsible for receiving email for a domain, each with a priority — lower numbers are tried first.
Why would a domain have no MX records?
Some domains (like the reserved example.com and example.net) intentionally don't accept mail and have no mail servers configured.

For a real production DNS check, `dig MX yourdomain.com` from a terminal remains the most authoritative source — MX Lookup previews how a clean, readable report of that data can look.
