Identity Findings
External report destination not authorized: medallia.com
The ruf= URI sends reports to medallia.com, but no authorization record exists at express.medallia.com._report._dmarc.medallia.com. Reports will be silently dropped by compliant receivers.
💡 Ask the owner of medallia.com to publish a TXT record at express.medallia.com._report._dmarc.medallia.com containing 'v=DMARC1'.
No PTR record for MX IP: 147.75.251.2
The IP 147.75.251.2 (for mx-176.mx.medallia.com) has no reverse DNS record.
💡 Configure a PTR record for the mail server IP.
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.express.medallia.com
Very low TTL on MX record: 291s
The MX record has a TTL of 291s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on SPF record: 290s
The SPF record has a TTL of 290s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on TXT records: 290s
2 TXT records have a TTL of 290s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on DMARC record: 295s
The DMARC record has a TTL of 295s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
SPF record is valid
The SPF record is properly configured with valid syntax and within lookup limits.
SPF record length OK (36 bytes)
SPF record is within safe DNS packet size limits.
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
DMARC alignment: adkim=r, aspf=r
DKIM alignment is relaxed, SPF alignment is relaxed.
DMARC failure reporting: fo=1
Failure reports generated when any authentication mechanism fails.
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.

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: reject
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: reject
⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
Mail Server Identity: mx-176.mx.medallia.com
PTR record proves mail server legitimacy
MX: mx-176.mx.medallia.com
Mail server at 147.75.251.2
→
PTR Record
No PTR record
⚠️ Mail server mx-176.mx.medallia.com (147.75.251.2) lacks a PTR record. Many receiving servers require matching forward and reverse DNS for spam prevention.
Mail Server Reputation: mx-176.mx.medallia.com
RBL check ensures server is not blacklisted
MX: mx-176.mx.medallia.com
Mail server at 147.75.251.2

RBL Status
Not blacklisted
Enforced Encryption Chain
MTA-STS enforces TLS encryption to prevent man-in-the-middle attacks
TLS Support
Mail servers support TLS encryption
→
MTA-STS Policy
MTA-STS not configured
⚠️ MTA-STS policy is missing. Even with TLS support, you lack the enforcement layer that prevents attackers from stripping encryption (downgrade attacks).
Brand Identity Chain
BIMI displays your logo in email clients, but requires DMARC enforcement
DMARC Enforcement
DMARC policy: reject
→
BIMI Record
BIMI not configured
⚠️ BIMI record is missing. Even with DMARC enforcement, you need to configure BIMI to display your brand logo in supported email clients.
TLS Monitoring Chain
TLS-RPT provides reports about TLS connection failures
TLS Support
Mail servers support TLS encryption
→
TLS-RPT Reporting
TLS-RPT not configured
⚠️ TLS-RPT is not configured. Without TLS reporting, you have no visibility into TLS connection failures that may be impacting email delivery.
