Identity Findings
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.
Weak DKIM RSA key (~1296 bits) for selector 's2'
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 mx1.hc2186-24.iphmx.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 mx2.hc2186-24.iphmx.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 mx1.hc2186-24.iphmx.com
The mail server does not support STARTTLS. All email is transmitted in plaintext.
💡 Enable STARTTLS on the mail server.
No STARTTLS support on mx2.hc2186-24.iphmx.com
The mail server does not support STARTTLS. All email is transmitted in plaintext.
💡 Enable STARTTLS on the mail server.
NS delegation mismatch
The registrar-delegated nameservers do not match the zone NS records.
💡 Update either the registrar NS delegation or the zone NS records to match.
Inconsistent DNS responses across nameservers
Authoritative nameservers return different answers for the same query.
💡 Verify zone transfers are working correctly and all nameservers serve the same zone data.
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.ebay.de/.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: esa.hc2186-24.iphmx.com
The PTR record for 216.71.152.175 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.ebay.de
Generic ISP PTR hostname: esa.hc2186-24.iphmx.com
The PTR record for 216.71.155.88 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.ebay.de
Generic ISP PTR hostname: esa.hc2186-24.iphmx.com
The PTR record for 216.71.155.88 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.ebay.de
Generic ISP PTR hostname: esa.hc2186-24.iphmx.com
The PTR record for 216.71.152.175 appears to be a generic ISP hostname, which can harm deliverability.
💡 Set a meaningful PTR record like mail.ebay.de
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@ebay.de").
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.
Shared IP 216.71.152.175 used by multiple MX servers
The IP 216.71.152.175 is shared across 2 MX hostnames, reducing redundancy.
💡 Use unique IP addresses for each MX server for better redundancy.
Shared IP 216.71.155.88 used by multiple MX servers
The IP 216.71.155.88 is shared across 2 MX hostnames, reducing redundancy.
💡 Use unique IP addresses for each MX server for better redundancy.
NS TTL mismatch between parent and authoritative zone
The NS record TTL in the parent zone (~7170s) differs significantly from the authoritative zone (~86400s).
💡 Align NS record TTLs between the parent zone delegation and the authoritative zone.
SPF record is valid
The SPF record is properly configured with valid syntax and within lookup limits.
SPF record length OK (177 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.
All external report destinations authorized
External DMARC report destinations have valid authorization records per RFC 7489 §7.1.
Subdomains protected (sp=reject)
DMARC subdomain policy enforces quarantine or reject on unauthenticated subdomain mail.
2 MX records with 2 unique IPs
Multiple MX records provide mail delivery redundancy.
BIMI record is valid
BIMI is properly configured with a valid logo and DMARC enforcement.
VMC URL is accessible
The BIMI VMC authority URL is reachable and returns a valid response.
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.
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.
Deprecated DMARCbis tags found: pct, rf
The DMARC record contains tags deprecated in DMARCbis: pct, rf. Consider removing these for forward compatibility.
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.
Open mail ports on mx1.hc2186-24.iphmx.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
All MX IPs are in the same /16 network. Consider diversifying across networks for resilience.
SOA record parameters
Serial: 2013115721, Refresh: 3600s, Retry: 1800s, Expire: 1209600s, Min TTL: 1800s
Authorized certificate authorities
CAA records restrict certificate issuance to: symantec.com, comodoca.com
Attack Surface Findings
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.
No excessive DNS information exposure detected
No HINFO, LOC, RP records, version disclosures, or zone walking vulnerabilities were found.
5 subdomain(s) discovered for ebay.de
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 ebay.de and its subdomains. Each certificate reveals subdomain names.
1 email SRV record(s) found
Email service SRV records expose mail server configuration for automatic client setup.
