Identity Findings
Weak DKIM RSA key (~1296 bits) for selector 'default'
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 's2'
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.
ARC support not detected
No evidence of ARC (Authenticated Received Chain) support on MX servers. Forwarded messages may lose authentication.
💡 Consider enabling ARC signing on your mail servers to preserve authentication through forwarding.
Very low TTL on TXT records: 276s
7 TXT records have a TTL of 276s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on SPF record: 276s
The SPF record has a TTL of 276s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on DMARC record: 276s
The DMARC record has a TTL of 276s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
NS TTL mismatch between parent and authoritative zone
The NS record TTL in the parent zone (~7176s) differs significantly from the authoritative zone (~86400s).
💡 Align NS record TTLs between the parent zone delegation and the authoritative zone.
SPF record is valid
The SPF record is properly configured with valid syntax and within lookup limits.
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
MTA-STS and TLS-RPT are properly configured
MTA-STS policy is enforced and TLS reporting is configured.
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.
IPv6 readiness is good
IPv6 records are present and properly configured.
STARTTLS downgrade resistance is adequate
STARTTLS is supported with modern TLS and protected by MTA-STS and/or DANE.
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.
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: pct
The DMARC record contains tags deprecated in DMARCbis: pct. 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: mx1.forwardemail.net
The MX record points to a known shared or free email hosting provider.
Shared/free email hosting detected: mx2.forwardemail.net
The MX record points to a known shared or free email hosting provider.
DANE/TLSA configured for mx1.forwardemail.net
TLSA records found and TLS certificate is available for verification.
DANE/TLSA configured for mx2.forwardemail.net

Open mail ports on mx1.forwardemail.net
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 3 different /16 networks, providing good diversity.
SOA record parameters
Serial: 2403390336, Refresh: 10000s, Retry: 2400s, Expire: 604800s, Min TTL: 1800s
Authorized certificate authorities

Attack Surface Findings
NSEC records enable zone walking
The domain uses NSEC records for DNSSEC authenticated denial of existence. NSEC records can be walked to enumerate all names in the zone, effectively disclosing the entire zone contents.
💡 Switch from NSEC to NSEC3 with opt-out to prevent zone enumeration. Use NSEC3 with a random salt and sufficient iterations.
Domain enumerability: high
The domain is highly enumerable. Zone transfers, NSEC zone walking, or a combination of factors make it easy to discover all DNS records.
💡 Restrict zone transfers, use NSEC3 instead of NSEC, consider wildcard certificates to reduce CT log exposure, and implement rate limiting on DNS queries.
Microsoft Autodiscover accessible without authentication
The Autodiscover endpoint at https://autodiscover.forwardemail.net/autodiscover/autodiscover.xml returns configuration data without requiring authentication. This exposes email server details to unauthenticated users.
💡 Configure the Autodiscover endpoint to require authentication before returning configuration data.
