How this service works
Permissive SPF policy check for Vendor screening: 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 uses a permissive qualifier (+all or ?all), along with a structured list of the SPF mechanisms found in the DNS TXT record. No email is sent and no inbox is verified — this is purely DNS-based lookup data.
Example use cases
Vendor onboarding security screening
“Before we onboard GlobalParts Inc. as a supplier, can you check if globalparters.com has a risky SPF policy like +all or ?all that could let anyone spoof their email address?”
Procurement risk audit for new contractors
“I'm reviewing three contractor domains for our procurement team — can you check if buildright-contractors.com is using a permissive SPF policy that flags it as an email spoofing risk?”
Security team supply chain review
“Our security team needs to flag any vendors with weak SPF configurations — can you check techpartners-ltd.com and tell me if its SPF record ends in +all or ?all and what mechanisms it includes?”

Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-spf-permissive-policy-vendor-screening?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, lightweight DNS-only check to screen vendor or partner domains for dangerous SPF permissiveness (+all or ?all) as part of a vendor risk or procurement workflow. It is ideal when you do not need full email deliverability testing or inbox verification — just a security flag on the SPF policy posture. Prefer this over a full email security audit tool when cost and speed matter and the question is specifically about SPF permissiveness.
Side effects
- Domain has no SPF record — returns not found or no SPF record response
- Domain does not exist in DNS — returns DNS resolution failure
- Domain uses a valid but non-permissive SPF policy — returns not flagged with policy details
- Malformed SPF record — may return parse error or incomplete mechanism list
- Network or DNS timeout — returns service unavailable
