Identity Findings
No SPF record found
The domain has no SPF record, allowing anyone to send email as this domain.
💡 Publish an SPF TXT record (e.g. "v=spf1 include:_spf.google.com -all").
No DMARC record found
The domain has no DMARC record, providing no policy for handling unauthenticated email.
💡 Publish a DMARC TXT record at _dmarc.upwind.ai (e.g. "v=DMARC1; p=reject; rua=mailto:dmarc@upwind.ai").
No MX records found
The domain has no MX records and cannot receive email.
💡 Publish MX records pointing to your mail server(s).
No DKIM records found
No DKIM records were found for any common selector. Email may not be authenticated.
💡 Configure DKIM signing and publish the public key at <selector>._domainkey.upwind.ai
Does not meet bulk sender requirements
Google and Yahoo require all bulk senders to have SPF+DKIM, DMARC, and one-click unsubscribe. Issues: Neither SPF nor DKIM is configured (at least one required); No DMARC record published (required since Feb 2024); SPF not published (recommended alongside DKIM)
💡 Publish SPF, DKIM, and DMARC records. Implement RFC 8058 one-click unsubscribe for marketing mail.
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.upwind.ai/.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@upwind.ai").
ARC check skipped — no MX records
Cannot assess ARC support without MX records.
Very low TTL on TXT record: 258s
The TXT record has a TTL of 258s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
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.
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
No DKIM signing detected. RFC 8058 one-click unsubscribe requires DKIM-signed List-Unsubscribe headers.
FCrDNS check skipped — no MX records
Cannot perform FCrDNS without MX records.
SOA record parameters
Serial: 1776463942, Refresh: 43200s, Retry: 3600s, Expire: 604800s, Min TTL: 3600s
Attack Surface Findings
Non-mail domain has no SPF record
This domain has no MX records (does not receive mail) but also has no SPF record. Without "v=spf1 -all", attackers can spoof this domain in phishing emails.
💡 Publish "v=spf1 -all" to explicitly declare this domain sends no mail.
No MX records — A-record fallback active
The domain has no MX records but has an A record. Per RFC 5321, mail servers will attempt delivery to the A record IP. This domain may be silently accepting mail without SPF/DKIM/DMARC protection.
💡 If this domain should not receive mail, publish a Null MX record (RFC 7505): "0 ." as the MX. If it should receive mail, add proper MX records.
Domain enumerability: low
The domain has low enumerability. Proper NSEC3 configuration and limited CT exposure reduce the attack surface.
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.
No email autodiscovery endpoints detected
No Microsoft Autodiscover, Mozilla Autoconfig, or email SRV records were found.
1 subdomain(s) discovered for upwind.ai
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 upwind.ai and its subdomains. Each certificate reveals subdomain names.
NSEC3 authenticated denial of existence
The domain uses NSEC3 with 0 iteration(s) and salt '-'.
DNSSEC is enabled
DNSKEY and/or DS records are present, indicating DNSSEC is configured.
Reputation Findings

Dependency Chains
DMARC Authentication Chain (SPF)
DMARC uses SPF to verify that emails come from authorized servers
SPF Record
SPF record missing
→
DMARC Policy
DMARC policy missing
⚠️ SPF record is missing. DMARC relies on SPF to verify sender authorization. Without SPF, DMARC alignment will fail, reducing email deliverability and brand protection.
DMARC Authentication Chain (DKIM)
DMARC uses DKIM to verify that emails have not been tampered with
DKIM Signature
DKIM signature missing
→
DMARC Policy
DMARC policy missing
⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
Enforced Encryption Chain
MTA-STS enforces TLS encryption to prevent man-in-the-middle attacks
TLS Support
TLS not verified or unsupported
→
MTA-STS Policy
MTA-STS not configured
⚠️ TLS support could not be verified. MTA-STS requires TLS to enforce encrypted connections. Without TLS, MTA-STS cannot function.
Brand Identity Chain
BIMI displays your logo in email clients, but requires DMARC enforcement
DMARC Enforcement
DMARC not enforced (p=none or missing)
→
BIMI Record
BIMI not configured
⚠️ DMARC is not enforced. BIMI requires a DMARC policy of "quarantine" or "reject" to prove you have strong email authentication. Without enforcement, email clients will not display your logo.
TLS Monitoring Chain
TLS-RPT provides reports about TLS connection failures
TLS Support
TLS not verified or unsupported
→
TLS-RPT Reporting
TLS-RPT not configured
⚠️ TLS support could not be verified. TLS-RPT reports on TLS connection failures, but without TLS support, there's nothing to monitor. You need working TLS encryption before TLS-RPT can provide value.
