How this service works
MX records for a domain as answered by OpenDNS (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 OpenDNS via DNS over HTTPS, including the record values (mail server hostnames and priorities), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer time in milliseconds.
Example use cases
Email deliverability diagnosis
“Something is wrong with email delivery to example.com — can you pull the MX records as seen by OpenDNS and tell me the response code, TTL, and whether DNSSEC validated?”
Resolver comparison for DNS propagation
“I just updated MX records for mycompany.com. Can you check what OpenDNS currently returns for those MX records so I can compare it against Cloudflare and see if propagation has reached OpenDNS yet?”
Detecting split-horizon or filtered DNS
“I suspect OpenDNS is returning different MX records for acmecorp.com than what's authoritative — can you query OpenDNS via DNS over HTTPS and show me the exact MX records, TTL, and response code they give back?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/mx/via/opendns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how OpenDNS resolves MX records for a domain — useful for comparing resolver behavior, detecting propagation lag, identifying filtering (OpenDNS is known for content filtering), or diagnosing split-horizon DNS. Prefer it over generic MX lookups when OpenDNS's perspective is relevant to email routing or security investigations.
Side effects
- Domain does not exist — returns NXDOMAIN response code
- Resolver fails to answer — returns SERVFAIL response code
- No MX records configured for domain — returns NOERROR with empty answer section
- Network timeout reaching OpenDNS — may result in error or no response
- Invalid domain format in query — likely 400 or validation error
