What Requires Attention
Critical No DMARC record
Recommended DKIM not applicable for no-mail domains — DKIM signing is only relevant for domains that send email
The BIG Questions
Can this domain be impersonated by email? Not Assessed
Can DNS itself be tampered with? Not Assessed
Can this brand be convincingly faked? Not Assessed
Is mail transport encryption enforced? Not Assessed
Is certificate issuance controlled? Not Assessed
Domain Overview
Registrar NameCheap, Inc.

DNS Security
DNSSEC Partial
DNSSEC not configured - DNS responses are unsigned
NS Delegation Healthy
Brand & Certificate Controls
BIMI (Brand Logo) Not Configured
CAA (Certificate) Open Any certificate authority may issue certificates
Priority Actions 5 total Achievable: Medium Risk
Critical Publish DMARC policy

DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receivers how to handle messages that fail SPF/DKIM checks. Without DMARC, failed authentication checks are ignored. Start with p=none and rua reporting to monitor, then escalate to p=quarantine and p=reject.

_dmarc.1liner.com TXT "v=DMARC1; p=none; rua=mailto:dmarc-reports@1liner.com"
Medium Deploy MTA-STS policy

Publish an MTA-STS DNS record and host a policy file at https://mta-sts.1liner.com/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.

_mta-sts.1liner.com TXT "v=STSv1; id=20240101"
Low Add CAA records

Publish CAA DNS records to restrict which Certificate Authorities can issue TLS certificates for your domain. Specify your preferred CA (e.g., letsencrypt.org, digicert.com). CAA is advisory — CAs must check it before issuing, but absence means any CA can issue.

1liner.com CAA 0 issue "letsencrypt.org"
Low Configure TLS-RPT reporting

TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain. Helps diagnose MTA-STS and STARTTLS issues.

_smtp._tls.1liner.com TXT "v=TLSRPTv1; rua=mailto:tls-reports@1liner.com"
Low Enable DNSSEC

DNSSEC (DNS Security Extensions) cryptographically signs DNS responses, preventing attackers from forging DNS answers. Contact your DNS hosting provider to enable DNSSEC signing.
