Identity Findings
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.ventasreit.com/.well-known/mta-sts.txt
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.
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"
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@ventasreit.com").
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.
Slow DNS response from ns-189.awsdns-23.com: 2075.8ms
The nameserver ns-189.awsdns-23.com responded in 2075.8ms, exceeding the 2000ms threshold.
💡 Investigate network latency or performance issues on ns-189.awsdns-23.com.
Very low TTL on MX records: 268s
2 MX records have a TTL of 268s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on TXT records: 267s
10 TXT records have a TTL of 267s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on SPF record: 267s
The SPF record has a TTL of 267s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on DMARC record: 267s
The DMARC record has a TTL of 267s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
SPF record is valid
The SPF record is properly configured with valid syntax and within lookup limits.
DKIM records are valid
DKIM records found and validated for selectors: selector1, selector2, dkim
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
DKIM key strength indicates modern key management
All DKIM keys use RSA-2048+ or Ed25519, consistent with current best practices.
No external DMARC report destinations
All DMARC report URIs point to the same domain — no external authorization needed.
Subdomains protected (sp=quarantine)
DMARC subdomain policy enforces quarantine or reject on unauthenticated subdomain mail.
No deprecated DMARCbis tags present
The DMARC record does not use any tags deprecated in DMARCbis (pct, rf, ri).
MX records are valid
All MX records are properly configured.
Meets bulk sender authentication requirements
Domain has SPF, DKIM, and DMARC — meeting Google/Yahoo 2024 bulk sender requirements for email authentication.
SMTP security checks passed
No open relay, VRFY/EXPN, or banner disclosure issues detected.
SMTP RFC 5321 compliance checks passed
The mail server accepts postmaster@ and abuse@ and uses a valid FQDN in EHLO.
IPv6 readiness is good
IPv6 records are present and properly configured.
NS delegation is properly configured
All nameservers are responsive, consistent, and properly secured.
SPF record is 368 bytes (multi-string TXT)
The SPF record exceeds 255 bytes and requires multi-string TXT encoding. Most modern resolvers handle this correctly.
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.
DMARC alignment: adkim=r, aspf=r
DKIM alignment is relaxed, SPF alignment is relaxed.
DMARC failure reporting: fo=1
Failure reports generated when any authentication mechanism fails.
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.
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.
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.
No DANE/TLSA records found
DANE is not configured for any MX server. This is optional but provides strong certificate binding.
No BIMI record found
BIMI is not configured. Your brand logo will not display in supporting email clients.
Open mail ports on usb-smtp-inbound-1.mimecast.com
Detected open mail-related ports: 25, 587
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.
MX IP network diversity
All MX IPs are in the same /16 network. Consider diversifying across networks for resilience.
SOA record parameters
Serial: 1, Refresh: 7200s, Retry: 900s, Expire: 1209600s, Min TTL: 86400s
Attack Surface Findings
Non-routable IPv4 in public DNS: smtp.ventasreit.com → 10.1.200.225
The subdomain smtp.ventasreit.com resolves to non-routable IP 10.1.200.225, leaking internal network information.
💡 Remove non-routable IPs from public DNS or implement split-horizon DNS.
Non-responsive IP for www.ventasreit.com: 2620:12a:8001::3
The subdomain www.ventasreit.com resolves to 2620:12a:8001::3 which is not responding on ports 80 or 443. This may indicate a decommissioned server.
💡 Verify the server at 2620:12a:8001::3 is operational or remove the DNS record for www.ventasreit.com.
Non-responsive IP for www.ventasreit.com: 2620:12a:8000::3
The subdomain www.ventasreit.com resolves to 2620:12a:8000::3 which is not responding on ports 80 or 443. This may indicate a decommissioned server.
💡 Verify the server at 2620:12a:8000::3 is operational or remove the DNS record for www.ventasreit.com.
Non-responsive IP for ftp.ventasreit.com: 209.12.208.41
