How this service works
Permissive SPF policy check for Email operations: Flag an SPF policy ending in +all or ?all and list its mechanisms. DNS data only; does not send email or verify that an inbox exists.
Output
Returns whether the domain's SPF record ends in a permissive qualifier (+all or ?all), flags the policy as permissive or not, and lists all SPF mechanisms (e.g. ip4, include, a, mx) found in the record. Data is sourced from public DNS; no email is sent and no inbox is verified.
Example use cases
Security audit of outbound email domains
“Can you check if acmecorp.com has a dangerously permissive SPF record? I want to know if it ends in +all or ?all and what mechanisms are listed.”
Pre-send phishing risk assessment
“Before I flag this suspicious email, check whether the sender domain fastdeals.biz has an open SPF policy that would let anyone spoof it — look for +all or ?all in its SPF record.”
Vendor email security review
“I'm vetting a new vendor and want to check their domain newvendor.io for permissive SPF settings — does their SPF record end in +all or ?all, and what mechanisms does it declare?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-spf-permissive-policy-email-operations?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to detect overly permissive SPF policies (+all or ?all) that could enable email spoofing or phishing. It is a focused DNS-only check ideal for security audits, vendor assessments, or pre-send phishing analysis. Prefer this over general SPF lookup tools when you need a clear pass/fail flag on permissiveness plus a structured list of mechanisms, and when you do not need to send a test email or verify inbox existence.
Side effects
- Domain has no SPF TXT record — returns no SPF found
- Domain does not exist in DNS — returns DNS resolution error
- Domain input is malformed or not a valid public DNS domain — returns validation error
- SPF record is present but uses -all or ~all (not permissive) — returns not flagged result
- Network or DNS timeout — returns service unavailable error
