Identity Findings
No MX records found
The domain has no MX records and cannot receive email.
💡 Publish MX records pointing to your mail server(s).
Weak DKIM RSA key (~1296 bits) for selector 'selector1'
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 'mandrill'
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 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.invitationhomes.com/.well-known/mta-sts.txt
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@invitationhomes.com").
ARC check skipped — no MX records
Cannot assess ARC support without MX records.
Very low TTL on TXT records: 293s
16 TXT records have a TTL of 293s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on SPF record: 293s
The SPF record has a TTL of 293s 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 (60 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=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.
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.
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.
DANE check skipped — no MX records
Cannot check DANE/TLSA without MX records.
No BIMI record found
BIMI is not configured. Your brand logo will not display in supporting email clients.
Open relay check skipped — no MX records
Cannot test for open relay without MX records.
SMTP compliance check skipped — no MX records
Cannot test SMTP compliance without MX records.
Port exposure check skipped — no MX records
Cannot scan ports without MX records.
STARTTLS downgrade check skipped — no MX records
Cannot test STARTTLS without MX records.
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.
FCrDNS check skipped — no MX records
Cannot perform FCrDNS without MX records.
SOA record parameters
Serial: 2404282758, Refresh: 10000s, Retry: 2400s, Expire: 604800s, Min TTL: 1800s
