Identity Findings

Open recursion on nameserver: pns3.thexyz.com
The nameserver pns3.thexyz.com allows recursive queries from external sources, making it vulnerable to DNS amplification attacks.
💡 Disable recursion on pns3.thexyz.com or restrict it to trusted networks only.
critical
Open recursion on nameserver: pns4.thexyz.com
The nameserver pns4.thexyz.com allows recursive queries from external sources, making it vulnerable to DNS amplification attacks.
💡 Disable recursion on pns4.thexyz.com or restrict it to trusted networks only.
critical
Open recursion on nameserver: pns2.thexyz.com
The nameserver pns2.thexyz.com allows recursive queries from external sources, making it vulnerable to DNS amplification attacks.
💡 Disable recursion on pns2.thexyz.com or restrict it to trusted networks only.
critical
Open recursion on nameserver: pns1.thexyz.com
The nameserver pns1.thexyz.com allows recursive queries from external sources, making it vulnerable to DNS amplification attacks.
💡 Disable recursion on pns1.thexyz.com or restrict it to trusted networks only.
critical
Weak DKIM RSA key (~1296 bits) for selector 'k1'
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.
high
Subdomains have no DMARC enforcement
sp=none explicitly allows unauthenticated mail from subdomains.
💡 Add sp=reject (or sp=quarantine) to your DMARC record to protect subdomains.
high
TLS certificate hostname mismatch on mx.thexyz.com
Certificate subject '*.emailarray.com' does not match hostname 'mx.thexyz.com'. SANs: *.emailarray.com, emailarray.com
💡 Obtain a TLS certificate that matches the mail server hostname.
high
TLS certificate hostname mismatch on mx2.thexyz.com
Certificate subject '*.emailarray.com' does not match hostname 'mx2.thexyz.com'. SANs: *.emailarray.com, emailarray.com
💡 Obtain a TLS certificate that matches the mail server hostname.
high
Subdomain policy (sp=none) is weaker than domain policy (p=quarantine)
The subdomain policy is less restrictive than the organizational domain policy, leaving subdomains more vulnerable.
💡 Set sp=quarantine or remove sp= to inherit the domain policy.
medium
MTA-STS is in testing mode
The MTA-STS policy is in testing mode and not actively enforcing TLS.
💡 Switch mode to "enforce" once TLS is confirmed working for all MX hosts.
low
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.
low
Shared IP 65.39.216.33 used by multiple MX servers
The IP 65.39.216.33 is shared across 2 MX hostnames, reducing redundancy.
💡 Use unique IP addresses for each MX server for better redundancy.
low
Shared IP 65.39.216.37 used by multiple MX servers
The IP 65.39.216.37 is shared across 2 MX hostnames, reducing redundancy.
💡 Use unique IP addresses for each MX server for better redundancy.
low
Shared IP 65.39.216.41 used by multiple MX servers
The IP 65.39.216.41 is shared across 2 MX hostnames, reducing redundancy.
💡 Use unique IP addresses for each MX server for better redundancy.
low
No CAA iodef tag configured
No iodef tag is present in the CAA records. CA policy violation reports will not be sent.
💡 Add an iodef CAA record. Example: 0 iodef "mailto:security@example.com"
low
Very low TTL on MX records: 275s
2 MX records have a TTL of 275s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
low
Very low TTL on TXT records: 275s
2 TXT records have a TTL of 275s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
low
Very low TTL on SPF record: 275s
The SPF record has a TTL of 275s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
low
NS TTL mismatch between parent and authoritative zone
The NS record TTL in the parent zone (~7175s) differs significantly from the authoritative zone (~86400s).
💡 Align NS record TTLs between the parent zone delegation and the authoritative zone.
low

informational
DMARC alignment: adkim=r, aspf=r
DKIM alignment is relaxed, SPF alignment is relaxed.
informational
DMARCbis np tag absent

Dependency Chains

DMARC Authentication Chain (SPF)
DMARC uses SPF to verify that emails come from authorized servers
SPF Record SPF record found and configured DMARC Policy DMARC policy: quarantine
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: quarantine
⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
