Identity Findings

Weak DKIM RSA key (~1296 bits) for selector 'google'
RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.
๐Ÿ’ก Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.
high
Weak DKIM RSA key (~1296 bits) for selector 's2'
RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.
๐Ÿ’ก Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.
high
Weak DKIM RSA key (~1296 bits) for selector 'mandrill'
RSA keys shorter than 2048 bits are considered weak. Current key is approximately 1296 bits.
๐Ÿ’ก Generate a new 2048-bit (or larger) RSA key pair and update the DKIM record.
high
NS delegation mismatch
The registrar-delegated nameservers do not match the zone NS records.
๐Ÿ’ก Update either the registrar NS delegation or the zone NS records to match.
high
Inconsistent DNS responses across nameservers
Authoritative nameservers return different answers for the same query.
๐Ÿ’ก Verify zone transfers are working correctly and all nameservers serve the same zone data.
high
No MTA-STS record found
Without MTA-STS, mail transport encryption cannot be enforced and is vulnerable to downgrade attacks.
๐Ÿ’ก Publish a _mta-sts TXT record and host a policy file at https://mta-sts.salesforce.com/.well-known/mta-sts.txt
medium
STARTTLS without MTA-STS or DANE protection
STARTTLS alone is vulnerable to downgrade attacks. Neither MTA-STS nor DANE is configured to enforce encryption.
๐Ÿ’ก Deploy MTA-STS and/or DANE to protect against STARTTLS stripping attacks.
medium
SOA MNAME does not resolve
The primary nameserver (MNAME) 'mastername.salesforce.com' does not resolve to any IP address.
๐Ÿ’ก Ensure the MNAME field points to a resolvable, authoritative nameserver.
medium
No CAA records found
No CAA records are configured. Any certificate authority can issue certificates for this domain.
๐Ÿ’ก Add CAA records to restrict certificate issuance. Example: 0 issue "letsencrypt.org"
medium
No TLS-RPT record found
Without TLS-RPT, you will not receive reports about TLS negotiation failures.
๐Ÿ’ก Publish a _smtp._tls TXT record (e.g. "v=TLSRPTv1; rua=mailto:tls-reports@salesforce.com").
low

6 NS records have a TTL of 283s or less (below 300s).
๐Ÿ’ก Increase the TTL to at least 300 seconds unless frequent changes are expected.
low
Very low TTL on DMARC record: 283s
The DMARC record has a TTL of 283s or less (below 300s).

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.
informational
DMARC alignment: adkim=r, aspf=r
DKIM alignment is relaxed, SPF alignment is relaxed.
informational
DMARC failure reporting: fo=1:d:s
Failure reporting option: 1:d:s

The primary MX does not advertise REQUIRETLS (RFC 8689). This is an emerging standard โ€” MTA-STS and DANE provide adequate TLS enforcement for most deployments.
informational
No DANE/TLSA records found
DANE is not configured for any MX server. This is optional but provides strong certificate binding.
informational
No VMC authority URL in BIMI record

Dependency Chains

DMARC Authentication Chain (SPF)
DMARC uses SPF to verify that emails come from authorized servers
SPF Record SPF record found and configured โ†’ DMARC Policy DMARC policy: reject
DMARC Authentication Chain (DKIM)
DMARC uses DKIM to verify that emails have not been tampered with
DKIM Signature DKIM signature missing โ†’ DMARC Policy DMARC policy: reject
โš ๏ธ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
