Identity Findings
No NS records found
No nameserver records could be retrieved for this domain.
💡 Ensure NS records are properly configured at your registrar and in your zone file.
Weak DKIM RSA key (~1296 bits) for selector 'dkim'
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.
No STARTTLS support on mx5.huawei.com:25
The mail server does not advertise STARTTLS, meaning email is transmitted in plaintext.
💡 Enable STARTTLS on the mail server.
No STARTTLS support on mx9.his.huawei.com:25
The mail server does not advertise STARTTLS, meaning email is transmitted in plaintext.
💡 Enable STARTTLS on the mail server.
FCrDNS mismatch: 119.8.89.70 → ecs-119-8-89-70.compute.hwclouds-dns.com does not resolve back
PTR for 119.8.89.70 is ecs-119-8-89-70.compute.hwclouds-dns.com, but ecs-119-8-89-70.compute.hwclouds-dns.com does not resolve back to 119.8.89.70.
💡 Ensure the PTR hostname resolves back to the original IP address.
FCrDNS mismatch: 124.71.93.234 → ecs-124-71-93-234.compute.hwclouds-dns.com does not resolve back
PTR for 124.71.93.234 is ecs-124-71-93-234.compute.hwclouds-dns.com, but ecs-124-71-93-234.compute.hwclouds-dns.com does not resolve back to 124.71.93.234.
💡 Ensure the PTR hostname resolves back to the original IP address.
FCrDNS mismatch: 119.8.177.45 → ecs-119-8-177-45.compute.hwclouds-dns.com does not resolve back
PTR for 119.8.177.45 is ecs-119-8-177-45.compute.hwclouds-dns.com, but ecs-119-8-177-45.compute.hwclouds-dns.com does not resolve back to 119.8.177.45.
💡 Ensure the PTR hostname resolves back to the original IP address.
FCrDNS failure: no PTR for 14.137.139.134 (mx9.his.huawei.com)
The IP 14.137.139.134 has no PTR record. Forward-confirmed reverse DNS requires a PTR that resolves back to the IP.
💡 Configure a PTR record for the IP that matches the mail server hostname.
Cannot check DNS consistency — no NS records
No nameserver records could be retrieved for consistency checking.
💡 Ensure NS records are properly configured.
No PTR record for MX IP: 14.137.139.134
The IP 14.137.139.134 (for mx9.his.huawei.com) has no reverse DNS record.
💡 Configure a PTR record for the mail server IP.
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.huawei.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.
Generic ISP PTR hostname: ecs-119-8-89-70.compute.hwclouds-dns.com
The PTR record for 119.8.89.70 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.huawei.com
Generic ISP PTR hostname: ecs-124-71-93-234.compute.hwclouds-dns.com
The PTR record for 124.71.93.234 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.huawei.com
Generic ISP PTR hostname: ecs-119-8-177-45.compute.hwclouds-dns.com
The PTR record for 119.8.177.45 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.huawei.com
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@huawei.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.
SPF record is valid
The SPF record is properly configured with valid syntax and within lookup limits.
SPF record length OK (169 bytes)
SPF record is within safe DNS packet size limits.
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).
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.
DNS TTL values follow best practices
All critical DNS record TTLs are within recommended ranges.
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.
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 mx7.huawei.com
Detected open mail-related ports: 25
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
MX IPs span 3 different /16 networks, providing good diversity.
SOA record parameters
Serial: 36769, Refresh: 14400s, Retry: 1800s, Expire: 604800s, Min TTL: 600s
Attack Surface Findings
DNS ANY query returns 33 record(s)
The DNS server responds to ANY queries with 33 record(s), creating significant DNS amplification risk.
💡 Configure the DNS server to refuse or minimize ANY query responses per RFC 8482.
Domain enumerability: medium
The domain has moderate enumerability. CT logs and DNS records reveal significant information about the domain structure.
💡 Restrict zone transfers, use NSEC3 instead of NSEC, consider wildcard certificates to reduce CT log exposure, and implement rate limiting on DNS queries.
DNSSEC is not enabled
No DNSKEY or DS records were found. DNS responses are not cryptographically authenticated.
💡 Enable DNSSEC by generating DNSKEY records and publishing DS records at the registrar.
All MX records resolve correctly
No dangling MX records detected — all MX hostnames resolve to valid IP addresses.
Explicit MX records present
The domain has explicit MX records — no implicit A-record fallback delivery.
No internal information leakage detected
No non-routable IP addresses or internal references were found in public DNS records.
13 subdomain(s) discovered for huawei.com
Subdomains were enumerated via Certificate Transparency logs, DNS wordlist brute-forcing, and DNS record analysis.
0 certificate(s) found in CT logs
Certificate Transparency logs contain 0 certificate(s) for huawei.com and its subdomains. Each certificate reveals subdomain names.
Microsoft Autodiscover endpoint detected (authenticated)
The Autodiscover endpoint at autodiscover.huawei.com is active and requires authentication.
