Identity Findings

Overly broad CIDR range: 66.161.0.0/16
The /16 CIDR block authorizes a very large IP range to send email as this domain.
💡 Narrow the IP range to only the specific servers that send email.
high
Weak DKIM RSA key (~1296 bits) for selector 'selector1'
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
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.wynnresorts.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@wynnresorts.com").
low
ARC support not detected
No evidence of ARC (Authenticated Received Chain) support on MX servers. Forwarded messages may lose authentication.
💡 Consider enabling ARC signing on your mail servers to preserve authentication through forwarding.
low
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
No deprecated DMARCbis tags present
The DMARC record does not use any tags deprecated in DMARCbis (pct, rf, ri).
pass
MX records are valid
All MX records are properly configured.
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
SPF record is 381 bytes (multi-string TXT)
The SPF record exceeds 255 bytes and requires multi-string TXT encoding. Most modern resolvers handle this correctly.
informational
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
DMARC failure reporting: fo=1
Failure reports generated when any authentication mechanism fails.
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
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
REQUIRETLS not advertised
The primary MX does not advertise REQUIRETLS (RFC 8689). This is an emerging standard — MTA-STS and DANE provide adequate TLS enforcement for most deployments.
informational
No DANE/TLSA records found
DANE is not configured for any MX server. This is optional but provides strong certificate binding.
informational
No BIMI record found
BIMI is not configured. Your brand logo will not display in supporting email clients.
informational
Open mail ports on mxa-0014ad01.gslb.pphosted.com
Detected open mail-related ports: 25
informational
RFC 8058 one-click unsubscribe assessment
DKIM signing is configured. RFC 8058 compliance depends on List-Unsubscribe and List-Unsubscribe-Post headers being included in outbound messages and DKIM signatures.
informational
MX IP network diversity
MX IPs span 2 different /16 networks, providing good diversity.
informational
SOA record parameters
Serial: 2404273451, Refresh: 10000s, Retry: 2400s, Expire: 604800s, Min TTL: 1800s

Attack Surface Findings

Non-responsive IP for www.wynnresorts.com: 2606:4700::6812:1b7b
The subdomain www.wynnresorts.com resolves to 2606:4700::6812:1b7b which is not responding on ports 80 or 443. This may indicate a decommissioned server.

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.

Enforced Encryption Chain
MTA-STS enforces TLS encryption to prevent man-in-the-middle attacks
TLS Support Mail servers support TLS encryption MTA-STS Policy MTA-STS not configured
⚠️ MTA-STS policy is missing. Even with TLS support, you lack the enforcement layer that prevents attackers from stripping encryption (downgrade attacks).
Brand Identity Chain
BIMI displays your logo in email clients, but requires DMARC enforcement
DMARC Enforcement DMARC policy: quarantine BIMI Record BIMI not configured
⚠️ BIMI record is missing. Even with DMARC enforcement, you need to configure BIMI to display your brand logo in supported email clients.
TLS Monitoring Chain
TLS-RPT provides reports about TLS connection failures
TLS Support Mail servers support TLS encryption TLS-RPT Reporting TLS-RPT not configured
⚠️ TLS-RPT is not configured. Without TLS reporting, you have no visibility into TLS connection failures that may be impacting email delivery.
