Identity Findings

Subdomains have no DMARC enforcement
No sp= tag set and p=none. Subdomains inherit the monitoring-only policy, leaving them open to spoofing.
💡 Add sp=reject (or sp=quarantine) to your DMARC record to protect subdomains.
high
No STARTTLS support on mx.1cbo.ru:25
The mail server does not advertise STARTTLS, meaning email is transmitted in plaintext.
💡 Enable STARTTLS on the mail server.
high
No DKIM records found
No DKIM records were found after probing 56 common selectors. The domain may use a custom selector not discoverable via external scan.
💡 Configure DKIM signing and publish the public key at <selector>._domainkey.1capp.com
medium
DMARC policy is monitoring-only (p=none)
The p=none policy only monitors; it does not instruct receivers to quarantine or reject unauthenticated mail.
💡 Upgrade to p=quarantine or p=reject after reviewing aggregate reports.
medium
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.1capp.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.
💡 Deploy MTA-STS and/or DANE to protect against STARTTLS stripping attacks.
medium
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"
medium
Void lookup: mx:mx.1cbo.ru
The mechanism mx:mx.1cbo.ru returns no records, wasting a DNS lookup.
💡 Remove mechanisms that reference non-existent domains.
low
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@1capp.com").
low
SPF record length OK (113 bytes)
SPF record is within safe DNS packet size limits.
pass
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
pass
No external DMARC report destinations
All DMARC report URIs point to the same domain — no external authorization needed.
pass
No deprecated DMARCbis tags present
The DMARC record does not use any tags deprecated in DMARCbis (pct, rf, ri).
pass
ARC support likely available
MX server software appears to support ARC headers for authentication preservation.
pass
Meets bulk sender authentication requirements
Domain has SPF, DKIM, and DMARC — meeting Google/Yahoo 2024 bulk sender requirements for email authentication.
pass
SMTP security checks passed
No open relay, VRFY/EXPN, or banner disclosure issues detected.
pass
SMTP RFC 5321 compliance checks passed
The mail server accepts postmaster@ and abuse@ and uses a valid FQDN in EHLO.
pass
NS delegation is properly configured
All nameservers are responsive, consistent, and properly secured.
pass
DNS responses are consistent across all nameservers
All authoritative nameservers return consistent answers with proper AA flags.
pass
DNS TTL values follow best practices
All critical DNS record TTLs are within recommended ranges.
pass
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
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.
informational
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.
informational
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.
informational
No DANE/TLSA records found
DANE is not configured for any MX server. This is optional but provides strong certificate binding.
informational
No BIMI record found
BIMI is not configured. Your brand logo will not display in supporting email clients.
informational
Open mail ports on mx.1cbo.ru
Detected open mail-related ports: 25, 465, 587
informational
Domain is IPv4-only
No AAAA records found for the domain, MX servers, or nameservers. The domain operates on IPv4 only.
informational
RFC 8058 one-click unsubscribe assessment
No DKIM signing detected. RFC 8058 one-click unsubscribe requires DKIM-signed List-Unsubscribe headers.
informational
MX IP network diversity
All MX IPs are in the same /16 network. Consider diversifying across networks for resilience.
informational
SOA record parameters

Attack Surface Findings

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.
medium
DNS ANY query returns 14 record(s)
The DNS server responds to ANY queries with 14 record(s). The low record count limits amplification risk, but ANY responses still aid reconnaissance.
💡 Configure the DNS server to refuse or minimize ANY query responses per RFC 8482.
low
Domain enumerability: low
The domain has low enumerability. Proper NSEC3 configuration and limited CT exposure reduce the attack surface.
low
All MX records resolve correctly
No dangling MX records detected — all MX hostnames resolve to valid IP addresses.
pass
Explicit MX records present
The domain has explicit MX records — no implicit A-record fallback delivery.
pass
No internal information leakage detected
No non-routable IP addresses or internal references were found in public DNS records.
pass
11 subdomain(s) discovered for 1capp.com
Subdomains were enumerated via Certificate Transparency logs, DNS wordlist brute-forcing, and DNS record analysis.
informational
0 certificate(s) found in CT logs
Certificate Transparency logs contain 0 certificate(s) for 1capp.com and its subdomains. Each certificate reveals subdomain names.

A wildcard DNS record exists for *.1capp.com, resolving to 146.185.209.48, 91.219.227.236, 91.219.226.230. Wildcard records make subdomain brute-forcing less effective but may mask misconfigurations.
informational
Microsoft Autodiscover endpoint detected
The Autodiscover endpoint at autodiscover.1capp.com responded with HTTP 404.

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 failure reporting 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.
