Quick fix

Identify the source and exact reason for the listing.

What this finding means

SecuTest reports a listing only when the configured source returns a recognized listing code. Provider errors, public-resolver blocks, and rate limits remain indeterminate rather than clean or listed.

Interpretation boundary Use the exact evidence in your report. SecuTest reports externally observable conditions; it does not assume ownership, exploitability, or business intent when those cannot be proven remotely.

Why it matters

Security impact A domain listed by a reputable blocklist may experience email rejection, browser warnings, or loss of trust and can indicate abuse or compromise.

Step-by-step fix

Where to make the change

  • The compromised or abusive workload, sender, account, website, DNS record, or public IP identified in the evidence.
  • The named blocklist provider only after the root cause has been removed.

Remediation procedure

  1. Identify the source and exact reason for the listing.
  2. Contain compromised websites, mail accounts, DNS records, or sender infrastructure.
  3. Remove malicious content and rotate affected credentials.
  4. Request delisting only after the root cause is fixed and monitoring is active.

Commands and configuration examples

Replace example values with the hostname, selector, IP address, port, or provider values shown in your SecuTest evidence.

Verify the fix

  1. Query the provider through an authorized resolver or account.
  2. Review DNS, web, mail, and authentication logs for the listing period.
  3. Confirm the provider reports the domain as clear after remediation.
  4. Repeat the SecuTest scan.
Confirm the externally visible result

After DNS, CDN, certificate, mail, or application propagation completes, run a fresh SecuTest scan and compare the new evidence with the original finding.

Re-scan your domain

Common mistakes

  • Submitting repeated delisting requests before remediation.
  • Treating a provider access error as a listing.
  • Ignoring subdomains or redirected malicious content.
