How this service works
MX records for a domain as answered by CleanBrowsing (security filter) (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.
Output
Returns the MX records for the queried domain as answered by CleanBrowsing's security-filtering DNS over HTTPS resolver, including the mail exchanger hostnames and priorities, TTL value, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether DNSSEC was validated, and the resolver's answer time in milliseconds.
Example use cases
Email deliverability security audit
“Check the MX records for acme-corp.com through CleanBrowsing's security DNS filter — I want to know what mail servers are listed, whether DNSSEC validated, and the response code so I can confirm nothing is being filtered.”
Resolver propagation comparison
“I just updated the MX records for mydomain.io — can you query CleanBrowsing's DNS resolver for the current MX records and tell me the TTL and answer time so I can compare it against what other resolvers are showing?”
Split-horizon DNS detection
“Query CleanBrowsing DoH for the MX records of contoso.com and give me the full response including the response code and DNSSEC status — I'm trying to figure out if their security filter is returning a different answer than public resolvers.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/mx/via/cleanbrowsing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how CleanBrowsing's security-filtering DNS resolver answers MX queries — for example, to detect filtering, blocking, or split-horizon behavior, to validate DNSSEC enforcement, or to compare resolver-specific propagation timing for email infrastructure. Prefer it over generic MX lookup tools when the security filter's perspective on mail exchanger records is the point of interest.
Side effects
- NXDOMAIN response if the domain does not exist
- SERVFAIL if CleanBrowsing cannot resolve the domain or an upstream error occurs
- Empty MX record set if the domain has no MX records configured
- CleanBrowsing security filter may block or alter results for flagged domains
- Network timeout if the DoH resolver is temporarily unreachable
- Invalid domain input may result in an error response
