GrokIn brief
EasyDMARC SPF Checker checks record syntax, lookup trees, sources, and lookup limits. Learn how to interpret findings and verify a delivered message.
EasyDMARC offers a dedicated SPF Checker page alongside its combined domain-security scan. The SPF tool documentation describes syntax validation, lookup trees, sending sources and lookup-limit checks. Use those SPF results when troubleshooting the record, then verify a delivered message to establish actual authentication.
For the broader protocol guide, see the SPF learning hub.
At a glance
Quick takeaways
- EasyDMARC publishes a dedicated SPF Checker as well as a combined domain-security scan.
- Its SPF Checker documentation describes lookup trees, sending sources, syntax checks and the lookup limit.
- EasySPF is a separate managed SPF product.
- A DNS lookup cannot establish how a particular message authenticated; inspect a delivered message’s authentication results.
What this tool checks
Open EasyDMARC’s SPF Checker for the SPF-specific lookup workflow. Its documentation describes validation of record presence and syntax, lookup trees and sending sources. EasyDMARC also displays a broader domain scan; keep that risk summary separate from the SPF result.
EasyDMARC describes EasySPF as managed SPF flattening that stays within the lookup limit and updates automatically as senders change. Confirm the plan entitlement and review the resulting record; a free SPF lookup and managed remediation are different services.
Both tools only see what is published in public DNS. Neither confirms that the server actually sending your mail uses the domain the record was written for, or that a specific message authenticated on delivery. For a side-by-side look at how free SPF and DMARC checkers compare, see Palisade's comparison hub.
How to run the check
1. Pull the current SPF record yourself
Before trusting any score, query the domain's own TXT record so you have independent evidence:
dig +short TXT yourdomain.comLook for the line beginning with v=spf1. RFC 7208 permits exactly one SPF record per domain; a second one is a permanent error, not a second layer of protection.
2. Run the domain through EasyDMARC's scanner
Use the SPF-specific results from EasyDMARC’s SPF Checker to investigate syntax, authorized sources and lookup limits. A combined domain-risk label summarizes additional authentication signals and does not replace that record-level inspection.
3. Count the record's own DNS lookups
Read back through the record you pulled in step 1 and count every mechanism that triggers its own DNS lookup: include, a, mx, ptr, exists, and redirect. RFC 7208 caps SPF evaluation at 10 of these per check. Going over that ceiling produces a permanent error regardless of what any combined score reports.
Interpret the SPF-specific findings
Use EasyDMARC’s SPF Checker to inspect whether a record is present, its syntax, its lookup tree and its DNS-lookup limit. Compare authorized sources with the services that actually send for the domain. A successful DNS check does not establish that a delivered message passed SPF; inspect its authentication results separately.
Separate domain-scan ratings from SPF results
Risk assessment level: Low
EasyDMARC publishes Low, Medium and High domain-risk descriptions. Those descriptions do not establish an arithmetic weighting formula or prove that strong DKIM can cancel a failing SPF record. Inspect SPF-specific results and delivered-message authentication separately.
Risk assessment level: Medium or High
A broader Medium or High rating does not isolate the SPF fault. Inspect the SPF-specific result and RFC 7208: one SPF record and no more than ten DNS-querying terms, including recursive evaluation. An explicit terminal policy is recommended, but SPF can also use redirect or the default neutral result.
DMARC policy score out of 10
The combined scan displays a DMARC Policy score separately from its broader risk label. The public labels do not establish the complete scoring formula. Read the published p= policy directly with the DMARC checker to confirm the requested enforcement state.
An independent SPF result matrix
Because a combined score does not isolate SPF, the table below separates the raw SPF states defined by RFC 7208 from what each one means and what to do next. This is an original reference built from the RFC, not a reproduction of any vendor's output.
How to act on the result
For a missing or malformed record, republish it from the sending service’s current documentation rather than copying an old one from another domain. For a lookup count near or over 10, remove unused includes or evaluate EasySPF, which EasyDMARC describes as managed flattening that updates automatically as senders change. Confirm that the selected plan includes EasySPF.
For a record that reads as valid on both the combined score and the RFC checklist, the remaining question is whether the server that sent your last message actually matches the record and whether the return path aligns with the visible From domain. Palisade's SPF checker inspects the record directly rather than folding it into a combined score, which provides another way to inspect the SPF record.
Investigate this with your coding agent
Use this when a record already has five or six mechanisms and you cannot tell by eye whether it is near the 10-lookup ceiling. Export the record from your DNS provider or version-controlled zone file, and redact the domain name before handing it to the agent.
Agent handoff
Copy the prepared prompt
Give this to a coding agent that can inspect the relevant repository or configuration source of truth.
Problem: A domain's SPF TXT record may exceed RFC 7208's 10 DNS-lookup limit or contain a syntax error, and it is unclear which included domain accounts for the most lookups.
Evidence: The current SPF TXT record for the domain (redact the domain name and any internal hostnames), taken from `dig +short TXT yourdomain.com` or the DNS provider's export, plus the zone file or IaC source if one exists.
Repository scope: The DNS zone file, the Terraform or other IaC module defining the TXT record, and any script that generates it. No application code.
Constraints: Inspect before editing. Do not apply changes until I approve the proposed diff. Do not query external resolvers with the real production domain name if that is a concern; work from the redacted record text instead.
Requested output: A count of DNS-querying mechanisms (include, a, mx, ptr, exists, redirect) against the 10-lookup ceiling, a list of any syntax issues (missing v=spf1, missing or ambiguous terminating mechanism, more than one SPF record), and a minimal proposed rewrite naming the removed or merged mechanisms.
Verification: Re-run the same redacted record through Palisade's SPF checker or a fresh dig +short TXT query after a human applies the DNS change, and confirm the lookup count and syntax state both changed as expected.
Stop if: The task requires DNS provider credentials, API tokens, or write access to production DNS. Report findings only.Human approval required: Review the proposed diff and verification plan before allowing changes. Do not paste secrets, private keys, API tokens, unredacted headers, or customer data.
How to retest
After you change the record, propagation means the new value will not appear everywhere at once. Query the authoritative name server directly first:
dig +short TXT yourdomain.com @<authoritative-ns>Then query a public resolver such as 8.8.8.8 or 1.1.1.1 to see which value it currently returns; cached answers can differ until their TTL expires. Re-run the record checker after verifying the intended DNS value. A DNS lookup does not establish the receiver’s SPF evaluation for a message: inspect a delivered message and its authentication results separately.
Check the SPF record, then keep it accurate as senders change
A one-time SPF lookup shows the currently published record; it does not continuously monitor sending activity. When a new sending service is not authorized by that record, its messages can fail SPF authentication. Check authentication and identifier alignment separately. Palisade's DMARC Agent reads incoming aggregate reports, identifies sending-source and authentication issues, and prepares remediation work for human review and approval.

Frequently asked questions
How do I check if an SPF record is valid?
Query the domain’s TXT records and confirm exactly one SPF record begins with v=spf1. RFC 7208 permits no more than ten DNS-querying terms, including recursive evaluation. An explicit terminal policy is recommended; redirect and the default neutral result are also defined. Check the actual sending path separately.
Does DMARC override SPF?
No, DMARC does not replace or override SPF. It evaluates SPF and DKIM authentication together with identifier alignment, per RFC 9989. A message passes DMARC when either SPF or DKIM passes with alignment to the visible From domain. SPF can pass while DMARC fails if SPF is unaligned and there is no aligned DKIM pass. The DMARC policy requests handling for DMARC failures; the receiving system makes the final delivery decision.
Why did SPF cause my mail to be rejected?
An SPF failure does not alone establish a DMARC failure or determine delivery. DMARC passes when either SPF or DKIM passes with alignment. Too many DNS-querying terms can produce SPF permerror, and an unauthorized sending IP can fail SPF; inspect the full authentication results and the aligned DKIM result before attributing rejection to DMARC.
How does EasyDMARC work?
EasyDMARC’s SPF Checker documents record-presence and syntax checks, lookup trees and sending sources. The same page describes broader domain-risk ratings. Keep those ratings separate from the SPF result, and use a delivered message to establish authentication.
Does EasySPF fix a record that is already over the lookup limit?
EasyDMARC describes EasySPF as managed SPF flattening that stays within the lookup limit and updates automatically as senders change. Confirm the plan entitlement and review the resulting record; a free SPF lookup and managed remediation are different services.
