Identity Findings
Subdomains have no DMARC enforcement
No sp= tag set and p=none. Subdomains inherit the monitoring-only policy, leaving them open to spoofing.
💡 Add sp=reject (or sp=quarantine) to your DMARC record to protect subdomains.
FCrDNS failure: no PTR for 47.117.233.177 (mail2.eastmoney.com)
The IP 47.117.233.177 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.
No DKIM records found
No DKIM records were found after probing 56 common selectors. The domain may use a custom selector not discoverable via external scan.
💡 Configure DKIM signing and publish the public key at <selector>._domainkey.eastmoney.com
DMARC policy is monitoring-only (p=none)
The p=none policy only monitors; it does not instruct receivers to quarantine or reject unauthenticated mail.
💡 Upgrade to p=quarantine or p=reject after reviewing aggregate reports.
No DMARC aggregate report URI (rua=)
Without rua=, you will not receive aggregate reports about authentication results.
💡 Add rua=mailto:dmarc-reports@eastmoney.com to your DMARC record.
No PTR record for MX IP: 47.117.233.177
The IP 47.117.233.177 (for mail2.eastmoney.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.eastmoney.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.
SOA expire value too short
The SOA expire value is 86400s (<604,800s / 7 days). Secondary nameservers may stop serving the zone prematurely.
💡 Increase the SOA expire value to at least 604800 seconds (7 days).
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@eastmoney.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.
Very low TTL on TXT record: 60s
The TXT record has a TTL of 60s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on SPF record: 60s
The SPF record has a TTL of 60s 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.
SPF record length OK (52 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.
No external DMARC report destinations
All DMARC report URIs point to the same domain — no external authorization needed.
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.
NS delegation is properly configured
All nameservers are responsive, consistent, and properly secured.
DNS responses are consistent across all nameservers
All authoritative nameservers return consistent answers with proper AA flags.
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 mail2.eastmoney.com
Detected open mail-related ports: 25, 465, 993, 995
RFC 8058 one-click unsubscribe assessment
No DKIM signing detected. RFC 8058 one-click unsubscribe requires DKIM-signed List-Unsubscribe headers.
MX IP network diversity
All MX IPs are in the same /16 network. Consider diversifying across networks for resilience.
SOA record parameters
Serial: 2026010712, Refresh: 3600s, Retry: 1200s, Expire: 86400s, Min TTL: 600s
Attack Surface Findings
Microsoft Autodiscover accessible without authentication
The Autodiscover endpoint at https://autodiscover.eastmoney.com/autodiscover/autodiscover.xml returns configuration data without requiring authentication. This exposes email server details to unauthenticated users.
💡 Configure the Autodiscover endpoint to require authentication before returning configuration data.
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.
Domain enumerability: low
The domain has low enumerability. Proper NSEC3 configuration and limited CT exposure reduce the attack surface.
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.
No excessive DNS information exposure detected
No HINFO, LOC, RP records, version disclosures, or zone walking vulnerabilities were found.
5 subdomain(s) discovered for eastmoney.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 eastmoney.com and its subdomains. Each certificate reveals subdomain names.
Wildcard DNS record detected
A wildcard DNS record exists for *.eastmoney.com, resolving to 61.152.229.228. Wildcard records make subdomain brute-forcing less effective but may mask misconfigurations.
Mozilla Autoconfig endpoint detected
The Autoconfig endpoint at autoconfig.eastmoney.com is publicly accessible.
Reputation Findings
Missing domain locks: clientDeleteProhibited
Domain eastmoney.com is missing protective locks: clientDeleteProhibited.
💡 Enable clientTransferProhibited and clientDeleteProhibited locks through your registrar to prevent unauthorized transfers or deletions.
SMTP banner mismatch: welcome
The SMTP banner identifies as 'welcome' but the MX hostname is 'mail2.eastmoney.com'. Microsoft and other receivers flag this mismatch as suspicious infrastructure.
💡 Configure the SMTP server banner to match the MX hostname or PTR record (mail2.eastmoney.com).
Missing Strict-Transport-Security on eastmoney.com
The Strict-Transport-Security header is not set on https://eastmoney.com.
💡 Add the Strict-Transport-Security header with a max-age of at least 31536000 (1 year) and include the includeSubDomains directive.
Missing Strict-Transport-Security on webmail.eastmoney.com
The Strict-Transport-Security header is not set on https://webmail.eastmoney.com.
💡 Add the Strict-Transport-Security header with a max-age of at least 31536000 (1 year) and include the includeSubDomains directive.
Weak TLS configuration on primary MX
The primary MX server supports deprecated TLS versions or weak cipher suites: No Forward Secrecy (PFS): AES128-GCM-SHA256. Modern receivers penalize reputation for lack of strong encryption.
💡 Disable TLS 1.0/1.1, remove weak ciphers (RC4, 3DES), and ensure Forward Secrecy (ECDHE) is preferred.
