Email Security Methodology Can this domain be impersonated by email? No SPF and DMARC reject policy enforced

SPF Record RFC 7208 §4 Verified

Does this domain declare who may send email on its behalf? Yes
Success ~all 1/10 lookups

SPF valid with industry-standard soft fail (~all), 1/10 lookups

v=spf1 include:_u.it-help.tech._spf.smart.ondmarc.com ~all
RFC 7208 Conformant — This SPF record conforms to the syntax and semantics defined in RFC 7208 §4.
RFC Failure Mode: Unlike DMARC (where unknown tags are silently ignored per RFC 7489 §6.3), SPF with unrecognized mechanisms produces a PermError per RFC 7208 §4.6 — the record fails loudly rather than silently.
Related CVEs: CVE-2024-7208 (multi-tenant domain spoofing), CVE-2024-7209 (shared SPF exploitation), CVE-2023-51764 (SMTP smuggling bypasses SPF)
~all is the industry standard. Google, Apple, and most providers default to soft fail. CISA (BOD 18-01) and RFC 7489 confirm that DMARC policy — not SPF alone — is the primary enforcement control. Using ~all allows DKIM to be evaluated before a DMARC decision is made. This domain uses ~all + DMARC reject: the strongest compatible security stance, aligned with CISA and RFC guidance.

DMARC Policy RFC 7489 §6.3 Verified

Are spoofed emails rejected or quarantined? Yes — reject policy
Success p=reject

DMARC policy reject (100%) - excellent protection

v=DMARC1; p=reject; pct=100; sp=reject; rua=mailto:dc1e127b@inbox.ondmarc.com; adkim=r; aspf=r; fo=1; rf=afrf; ri=3600
Alignment: SPF relaxed DKIM relaxed sp=reject
RFC 7489 Conformant — DMARC record conforms to RFC 7489 §6.3 with full enforcement.
DMARCbis (Pending): draft-ietf-dmarc-dmarcbis will elevate DMARC to Standards Track, obsolete RFC 7489, replace pct= with t= (testing flag), add np= (non-existent subdomain policy), and mandate DNS tree walk for policy discovery instead of the Public Suffix List.
Related CVEs: CVE-2024-49040 (Exchange sender spoofing), CVE-2024-7208 (multi-tenant DMARC bypass)

DKIM Records RFC 6376 §3.6 Verified

Are outbound emails cryptographically signed? Yes — verified
Found

RFC 6376 Conformant — DKIM keys and signatures conform to RFC 6376 §3.6 (Internet Standard).
Known Vulnerabilities: DKIM l= tag body length vulnerability (attacker appends unsigned content to signed mail), weak key exploitation (keys below 1024-bit are cryptographically breakable per RFC 6376 §3.3.3), DKIM replay attacks (re-sending legitimately signed messages at scale)

MTA-STS RFC 8461 §3 Verified

Can attackers downgrade SMTP to intercept mail? No — TLS enforced
Success ENFORCE Policy Verified

MTA-STS enforced - TLS required for 1 mail server(s)

v=STSv1; id=1741123722267
Policy Details:
  • Mode: enforce
  • Max Age: 14 days (1209600 seconds)
  • MX Patterns: smtp.google.com

MTA-STS policy enforcement is evaluated in Mail Transport Security below.

TLS-RPT RFC 8460 §3 Verified

Will failures in TLS delivery be reported? Yes — reports configured
Success

TLS-RPT configured - receiving TLS delivery reports

v=TLSRPTv1; rua=mailto:dc1e127b@inbox.ondmarc.com;

DMARC External Reporting Authorization RFC 7489 §7.1

Are external report receivers authorized? Yes — all authorized
Success

All 1 external reporting domains properly authorized

External Domain Authorization Auth Record
inbox.ondmarc.com Authorized v=DMARC1;
DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? via MTA-STS (CA)
RFC 7672 §3 RFC 6698 §2 Not Available

DANE not available — Google Workspace does not support inbound DANE/TLSA on its MX infrastructure

DANE not deployable on Google Workspace

Google Workspace supports DANE for outbound mail verification but does not publish TLSA records for its MX hosts.

Recommended alternative: MTA-STS (already configured)

Note: Google Workspace does validate DANE/TLSA when sending mail to DANE-enabled recipients (outbound DANE).

Email Transport Security

Two mechanisms protect email in transit. DANE is the primary standard; MTA-STS is the alternative for domains that cannot deploy DNSSEC:

  • DNSSEC + DANE (RFC 7672) — Cryptographic chain of trust from DNS root to mail server certificate. Eliminates reliance on certificate authorities. No trust-on-first-use weakness. Requires DNSSEC.
  • MTA-STS (RFC 8461) — HTTPS-based policy requiring TLS for mail delivery. Works without DNSSEC but relies on CA trust and is vulnerable on first use (§10). Created for domains where “deploying DNSSEC is undesirable or impractical” (§2).
This domain uses MTA-STS — the best available option for Google Workspace. Since Google Workspace does not support inbound DANE, MTA-STS is the strongest transport security this domain can deploy. MTA-STS enforces TLS via HTTPS-based policy, protecting against downgrade attacks (RFC 8461).

Industry trend: Microsoft Exchange Online enforces inbound DANE with DNSSEC (GA October 2024), and providers like Proton Mail and Fastmail also support DANE. Google Workspace does not support DANE and relies on MTA-STS. Both mechanisms coexist because DANE is backward-compatible — senders skip the check if the domain isn't DNSSEC-signed (RFC 7672 §1.3).

Brand Security Can this brand be convincingly faked? No DMARC reject policy enforced, BIMI brand verification active, and certificate issuance restricted by CAA

BIMI BIMI Spec Verified Success No VMC SVG

Is the brand identity verified and displayed in inboxes? Yes

BIMI configured - logo validated (VMC recommended for Gmail)

BIMI works without VMC! VMC (Verified Mark Certificate) requires a registered trademark. Small businesses can use BIMI with just a logo - it shows in Apple Mail and some providers. Gmail requires VMC.

Logo validated (SVG) View full logo

CAA RFC 8659 §4 Verified Success IODEF

Does this domain restrict who can issue TLS certificates? Yes

CAA configured - only Let's Encrypt, Amazon can issue certificates (wildcard issuance: Let's Encrypt per RFC 8659 §4.3)

Authorized CAs: Let's Encrypt Amazon
0 iodef "mailto:hello@it-help.tech"
0 issue "letsencrypt.org"
0 issue "amazon.com"
0 issuewild "letsencrypt.org"
Since September 2025, all public CAs must verify domain control from multiple geographic locations (Multi-Perspective Issuance Corroboration, CA/B Forum Ballot SC-067). CAA records are now checked from multiple network perspectives before certificate issuance.
Vulnerability Disclosure Policy (security.txt) Is there a verified way to report security issues? Yes RFC 9116

security.txt properly configured

Analyze Another Domain

Confirm Your Email Configuration

This tool analyzes DNS records, but to verify actual email delivery, send a test email to Red Sift Investigate. Their tool shows exactly how your emails arrive, including SPF/DKIM/DMARC pass/fail results in the headers.

DATA FRESHNESS & METHODOLOGY

All security-critical records (SPF, DMARC, DKIM, DANE/TLSA, DNSSEC, MTA-STS, TLS-RPT, BIMI, CAA) are queried live from authoritative nameservers and cross-referenced against 5 independent public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, DNS4EU) at the time of each analysis. No security verdict uses cached data.

Registrar data (RDAP) is cached for up to 24 hours because domain ownership and registration details change infrequently. Certificate Transparency logs (subdomain discovery via RFC 6962) are cached for 1 hour because CT entries are append-only historical records. Sections using cached data are marked with a CACHED badge; live queries show LIVE.

Intelligence Sources

This analysis used 4 DNS resolvers (consensus), reverse DNS (PTR), Team Cymru (ASN attribution), IANA RDAP (registrar), crt.sh (CT logs), and SMTP probing (transport). All using open-standard protocols.

Verify Report Integrity SHA-3-512 Has this report been altered since generation? Verify below

This cryptographic hash seals the analysis data, domain, timestamp, and tool version into a tamper-evident fingerprint. Any modification to the report data will produce a different hash. This is distinct from the posture hash (used for drift detection) — the integrity hash uniquely identifies this specific report instance.
