How this service works
Does the domain's SPF record authorise github to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for github's include/ip mechanisms, returning yes/no, the matching mechanism and the full record. Confirms a vendor integration is wired for deliverability, or spots an unexpected sender. $0.01 per lookup.
Output
Returns a yes/no boolean indicating whether GitHub is authorized by the domain's SPF record, the specific SPF mechanism (e.g. include:_spf.github.com or an IP range) that matched, and the complete SPF TXT record as fetched via Cloudflare DNS-over-HTTPS.
Example use cases
Verify GitHub notifications deliverability
“We just set up GitHub to send commit notification emails through our domain techcorp.io — can you check if GitHub is actually authorized in techcorp.io's SPF record so we know the emails won't be rejected?”
Detect unexpected GitHub mail sender
“I want to make sure nobody sneaked GitHub into our SPF record without authorization — can you check if GitHub is listed as an allowed mail sender for acmecorp.com and show me the full SPF record?”
Pre-launch email integration audit
“Before we go live, verify that our domain startup.dev has GitHub properly included in its SPF record for sending transactional emails, and tell me the exact mechanism that matches.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/github?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, single-call check specifically for GitHub's email authorization in a domain's SPF record. It is ideal for automating vendor integration audits, pre-launch email deliverability checks, or security monitoring for unexpected senders. Prefer this over a generic SPF lookup tool when you only care about GitHub's authorization status and want a structured yes/no verdict with the matching mechanism highlighted.
Side effects
- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or has no DNS — lookup fails with an error
- SPF record is malformed or exceeds DNS lookup limits — may return parsing error
- GitHub not present in SPF — returns no with the full record for manual review
- Rate limiting or upstream DoH unavailability — may return timeout or service error
