Identity Findings

Weak DKIM RSA key (~1296 bits) for selector 'k1'

RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.

💡 Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.

high

Weak DKIM RSA key (~1296 bits) for selector 'smtpapi'

RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.

💡 Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.

high

MX hostname does not resolve: bbtdngecipeaon5mwcamny2rcuknaatkgw2kzwy6wwgae77gqzaq.mx-verification.google.com

The MX hostname has no A or AAAA records.

💡 Ensure the MX hostname resolves to a valid IP address.

high

No MTA-STS record found

Without MTA-STS, mail transport encryption cannot be enforced and is vulnerable to downgrade attacks.

💡 Publish a _mta-sts TXT record and host a policy file at https://mta-sts.crazygames.com/.well-known/mta-sts.txt

medium

STARTTLS without MTA-STS or DANE protection

STARTTLS alone is vulnerable to downgrade attacks. Neither MTA-STS nor DANE is configured to enforce encryption.

💡 Deploy MTA-STS and/or DANE to protect against STARTTLS stripping attacks.

medium

No CAA records found

No CAA records are configured. Any certificate authority can issue certificates for this domain.

💡 Add CAA records to restrict certificate issuance. Example: 0 issue "letsencrypt.org"

medium

No TLS-RPT record found

Without TLS-RPT, you will not receive reports about TLS negotiation failures.

💡 Publish a _smtp._tls TXT record (e.g. "v=TLSRPTv1; rua=mailto:tls-reports@crazygames.com").

low

SPF record is valid

The SPF record is properly configured with valid syntax and within lookup limits.

pass

SPF record length OK (88 bytes)

SPF record is within safe DNS packet size limits.

pass

DKIM cryptographic configuration is compliant

No RFC 8301 compliance issues detected in DKIM key configuration.

pass

DKIM key strength indicates modern key management

All DKIM keys use RSA-2048+ or Ed25519, consistent with current best practices.

pass

No external DMARC report destinations

All DMARC report URIs point to the same domain — no external authorization needed.

pass

Subdomains protected (sp=quarantine)

DMARC subdomain policy enforces quarantine or reject on unauthenticated subdomain mail.

pass

ARC support likely available

MX server software appears to support ARC headers for authentication preservation.

pass

Meets bulk sender authentication requirements

Domain has SPF, DKIM, and DMARC — meeting Google/Yahoo 2024 bulk sender requirements for email authentication.

pass

SMTP security checks passed

No open relay, VRFY/EXPN, or banner disclosure issues detected.

pass

SMTP RFC 5321 compliance checks passed

The mail server accepts postmaster@ and abuse@ and uses a valid FQDN in EHLO.

pass

IPv6 readiness is good

IPv6 records are present and properly configured.

pass

NS delegation is properly configured

All nameservers are responsive, consistent, and properly secured.

pass

DNS responses are consistent across all nameservers

All authoritative nameservers return consistent answers with proper AA flags.

pass

DNS TTL values follow best practices

All critical DNS record TTLs are within recommended ranges.

pass

DKIM2 not detected

No DKIM key record with v=2 was found across common selectors. DKIM2 is an emerging standard and not yet widely deployed.

informational

DMARC alignment: adkim=r, aspf=r

DKIM alignment is relaxed, SPF alignment is relaxed.

informational

DMARCbis np tag absent

The DMARC record does not include the np (non-existent subdomain policy) tag. Consider adding np=reject to protect non-existent subdomains under DMARCbis.

informational

Deprecated DMARCbis tags found: pct

The DMARC record contains tags deprecated in DMARCbis: pct. Consider removing these for forward compatibility.

informational

DMARCbis psd tag absent

The DMARC record does not include the psd (public suffix domain) indicator. Consider adding psd=n to explicitly identify this as an organizational domain.

informational

Shared/free email hosting detected: aspmx.l.google.com

The MX record points to a known shared or free email hosting provider.

informational

Attack Surface Findings

Dangling MX: bbtdngecipeaon5mwcamny2rcuknaatkgw2kzwy6wwgae77gqzaq.mx-verification.google.com does not resolve

The MX record points to bbtdngecipeaon5mwcamny2rcuknaatkgw2kzwy6wwgae77gqzaq.mx-verification.google.com which has no A record. This may indicate a decommissioned mail provider (Google Workspace). Attackers can potentially re-register this hostname to hijack inbound mail.

💡 Remove the stale MX record pointing to bbtdngecipeaon5mwcamny2rcuknaatkgw2kzwy6wwgae77gqzaq.mx-verification.google.com or update it to your current mail provider.

critical

Domain enumerability: high

The domain is highly enumerable. Zone transfers, NSEC zone walking, or a combination of factors make it easy to discover all DNS records.

💡 Restrict zone transfers, use NSEC3 instead of NSEC, consider wildcard certificates to reduce CT log exposure, and implement rate limiting on DNS queries.

Dependency Chains

DMARC Authentication Chain (SPF)

DMARC uses SPF to verify that emails come from authorized servers

SPF Record SPF record found and configured → DMARC Policy DMARC policy: quarantine

DMARC Authentication Chain (DKIM)

DMARC uses DKIM to verify that emails have not been tampered with

DKIM Signature DKIM signature missing → DMARC Policy DMARC policy: quarantine

⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
