Identity Findings
Multiple SPF records detected
Multiple SPF records cause undefined behavior per RFC 7208. Only one SPF record should exist.
💡 Merge all SPF records into a single TXT record.
Weak DKIM RSA key (~1296 bits) for selector 'google'
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.
External report destination not authorized: yenimedya.com.tr
The rua= URI sends reports to yenimedya.com.tr, but no authorization record exists at haberler.com._report._dmarc.yenimedya.com.tr. Reports will be silently dropped by compliant receivers.
💡 Ask the owner of yenimedya.com.tr to publish a TXT record at haberler.com._report._dmarc.yenimedya.com.tr containing 'v=DMARC1'.
External report destination not authorized: yenimedya.com.tr
The ruf= URI sends reports to yenimedya.com.tr, but no authorization record exists at haberler.com._report._dmarc.yenimedya.com.tr. Reports will be silently dropped by compliant receivers.
💡 Ask the owner of yenimedya.com.tr to publish a TXT record at haberler.com._report._dmarc.yenimedya.com.tr containing 'v=DMARC1'.
Subdomains have no DMARC enforcement
sp=none explicitly allows unauthenticated mail from subdomains.
💡 Add sp=reject (or sp=quarantine) to your DMARC record to protect subdomains.
Subdomain policy (sp=none) is weaker than domain policy (p=quarantine)
The subdomain policy is less restrictive than the organizational domain policy, leaving subdomains more vulnerable.
💡 Set sp=quarantine or remove sp= to inherit the domain policy.
External DMARC report destination not authorized: yenimedya.com.tr
The rua= URI points to yenimedya.com.tr but no authorization record exists at haberler.com._report._dmarc.yenimedya.com.tr.
💡 Ask the owner of yenimedya.com.tr to publish a TXT record at haberler.com._report._dmarc.yenimedya.com.tr with 'v=DMARC1'.
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.haberler.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@haberler.com").
SPF has ip4 mechanisms but no ip6
The SPF record authorizes IPv4 addresses but not IPv6. Your MX servers have AAAA records, so IPv6 mail delivery is possible without SPF authorization.
💡 Add ip6: mechanisms to the SPF record for your IPv6 mail server addresses.
SPF record length OK (132 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.
ARC support likely available
MX server software appears to support ARC headers for authentication preservation.
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.
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.
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.
DMARC failure reporting: fo=d:s
Failure reporting option: d:s
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: ri
The DMARC record contains tags deprecated in DMARCbis: ri. 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.
Shared/free email hosting detected: aspmx.l.google.com
The MX record points to a known shared or free email hosting provider.
Shared/free email hosting detected: alt1.aspmx.l.google.com
The MX record points to a known shared or free email hosting provider.
Shared/free email hosting detected: alt2.aspmx.l.google.com
The MX record points to a known shared or free email hosting provider.
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 aspmx.l.google.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 5 different /16 networks, providing good diversity.
SOA record parameters
Serial: 2405202599, Refresh: 10000s, Retry: 2400s, Expire: 604800s, Min TTL: 1800s
