Sender Authentication (SPF)
Learn how it works
Info
6/7 pass
Sender Authentication (SPF)
SPF policy does not use strict fail mode
The SPF policy does not fully reject unauthorized senders.
Medium
Domain Alignment (DMARC)
Learn how it works
Info
2/7 pass
Domain Alignment (DMARC)
DMARC policy is monitoring only
The DMARC policy uses p=none and does not ask receivers to block or quarantine failing mail.
High
Domain Alignment (DMARC)
DMARC subdomain policy is weak
Subdomains are not protected by an enforcement policy.
High
Domain Alignment (DMARC)
DMARC aggregate reporting is not configured
The DMARC record does not request aggregate reports, which reduces visibility into authentication failures.
Medium
Domain Alignment (DMARC)
DMARC alignment is relaxed
The DMARC record allows relaxed identifier alignment for DKIM or SPF.

Transport Encryption (SMTP TLS)

Info
4/5 pass
Transport Encryption (SMTP TLS)
Some mail servers are unreachable
At least one mail exchanger accepts SMTP connections on port 25, but one or more others do not respond.

Info
0/5 pass
Certificate Binding (DANE)
Some mail servers are unreachable
At least one mail exchanger accepts SMTP connections on port 25, but one or more others do not respond.
Medium
Certificate Binding (DANE)
No MX host TLSA zone is protected by DNSSEC
None of the MX hosts have DNSSEC on their TLSA lookup zones. DANE SMTP cannot function without DNSSEC, as sending servers will ignore TLSA records from unsigned zones.
Critical
Mail Servers (MX)

Info
3/4 pass
Mail Servers (MX)
Some mail servers are unreachable
At least one mail exchanger accepts SMTP connections on port 25, but one or more others do not respond.

Info
0/6 pass
Transport Policy (MTA-STS)
Some mail servers are unreachable
At least one mail exchanger accepts SMTP connections on port 25, but one or more others do not respond.
Medium
Transport Policy (MTA-STS)
MTA-STS DNS record is missing
The domain does not publish an MTA-STS TXT record, so sending servers cannot discover or enforce an MTA-STS policy.
High
TLS Reporting (TLS-RPT)
Learn how it works
Info
0/4 pass
TLS Reporting (TLS-RPT)
Some mail servers are unreachable
At least one mail exchanger accepts SMTP connections on port 25, but one or more others do not respond.
Medium
TLS Reporting (TLS-RPT)
No TLS-RPT record found
The domain does not publish a TLS-RPT record. Sending servers cannot report TLS errors to this domain.

Info
0/7 pass
DNS Integrity (DNSSEC)
DNSSEC is not enabled
The parent zone does not publish a DS record for this domain.

Info
6/8 pass
DNS Health (Delegation & Exposure)
SOA serial does not use the recommended format
The SOA record is otherwise valid, but the serial number does not follow the recommended YYYYMMDDnn date format.
Low
DNS Health (Delegation & Exposure)
Zone transfer exposure could not be checked
The nameservers could not be probed for AXFR reliably.

CAA and Certificate Issuance Surface
Learn how it works
Info
1/6 pass
CAA and Certificate Issuance Surface
No CAA record is published
The domain does not publish a CAA record, so any publicly trusted certificate authority may issue certificates for it after standard validation.
Low
TLS

TLS Configuration
Learn how it works
Info
5/6 pass
TLS Configuration
Weak elliptic curve accepted for key exchange
The server negotiates an elliptic curve below 256 bits for at least one ECDHE cipher suite. Weak curves reduce the effective security margin of the key exchange well below modern standards.

Disclosure Policy (security.txt)
Learn how it works
Info
2/4 pass
Disclosure Policy (security.txt)
Expires field is missing, invalid, or expired
The security.txt file does not contain exactly one valid, in-date Expires field with an explicit timezone. The field is either absent, present more than once, not a valid date-time with a timezone offset, or its date is in the past. An expired file should not be used by security researchers.
Medium
Disclosure Policy (security.txt)
Canonical does not include the retrieval URL
The Canonical field is present but no valid Canonical URI matches the URL used to retrieve this file (mismatch, or all Canonical URIs are malformed). Such a file should not be trusted by security researchers.
