How this service works
Mail exchanger lookup for Security review: Return the domain MX hosts and their delivery priorities. DNS data only; does not send email or verify that an inbox exists.
Output
A list of MX records for the queried domain, each containing the mail exchanger hostname and its associated delivery priority integer. Pure DNS data — no email is sent and no inbox existence is verified.
Example use cases
Email infrastructure security audit
“I'm reviewing the email security posture of acme.com — can you pull its MX records so I can see which mail servers handle its inbound email and in what priority order?”
Phishing domain investigation
“I'm investigating a suspicious domain, suspicious-lookalike.com — look up its MX records so I can see if it's set up to receive email, which would suggest it's being used for phishing.”
Third-party vendor email routing check
“Before we start working with vendor.io, I need to know their mail infrastructure — can you fetch the MX records for vendor.io to confirm how their email is routed and which providers they use?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-mx-records-security-review?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve DNS MX records for a domain as part of a security review, vendor assessment, phishing investigation, or email infrastructure audit. Prefer this over general DNS tools when you want a structured, machine-readable response with host and priority fields. Do not use this to verify whether a specific email inbox exists or to send email.
Side effects
- Domain does not exist or has no MX records — returns empty result or DNS NXDOMAIN
- Invalid or malformed domain input — validation error returned
- DNS resolution timeout — transient failure, retry recommended
- Private or internal domains not resolvable via public DNS — no results returned
