DNS / SPF / DKIM / DMARC Audit API

Bulk-audit domains for SPF, DKIM, DMARC, MX, and email-auth posture with grades and fix-ready recommendations.

Store Quickstart

• Start with store-input.example.json to validate the output shape with three known domains.
• If that matches your audit workflow, switch to store-input.templates.json and pick one of:
  • Quickstart (Dataset) for a cheap first run
  • Security Audit (DKIM Enabled) for fuller grading
  • Weekly Portfolio Monitor for recurring customer/domain checks
  • Webhook Alert for automated notifications

Key Features

• 📧 Complete email security audit — SPF, DKIM, DMARC, and MX records
• 📊 Security scoring — 0-100 points with A-F grade
• 🔍 DKIM multi-selector check — Tests 6 common selectors (Google, Microsoft, etc.)
• 💡 Actionable recommendations — Specific fix suggestions for each issue
• 📋 Bulk processing — Check up to 500 domains per run
• 🪝 Webhook support — Send results to Slack/Discord

Use Cases

Who	Why
Developers	Automate recurring data fetches without building custom scrapers
Data teams	Pipe structured output into analytics warehouses
Ops teams	Monitor changes via webhook alerts
Product managers	Track competitor/market signals without engineering time

Input

Field	Type	Default	Description
domains	array	prefilled	List of domains to check email security for. Maximum 500 per run.
checkDkim	boolean	true	Check for DKIM records (common selectors: google, default, selector1, selector2).
dkimSelectors	array	—	Custom DKIM selectors to check. Defaults: google, default, selector1, selector2, k1, dkim.
delivery	string	"dataset"	How to deliver results. 'dataset' saves to Apify Dataset (recommended), 'webhook' sends to a URL.
webhookUrl	string	—	Webhook URL to send results to (only used when delivery is 'webhook'). Works with Slack, Discord, or any HTTP endpoint.
concurrency	integer	5	Maximum number of parallel requests. Higher = faster but may trigger rate limits.
dryRun	boolean	false	If true, runs without saving results or sending webhooks. Useful for testing.

Input Example

{
  "domains": ["google.com", "github.com", "example.com"],
  "checkDkim": true,
  "concurrency": 5
}

API Usage

Run this actor programmatically using the Apify API. Replace YOUR_API_TOKEN with your token from Apify Console → Settings → Integrations.

cURL

curl -X POST "https://api.apify.com/v2/acts/taroyamada~dns-dmarc-security-checker/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "domains": ["google.com", "github.com", "example.com"], "checkDkim": true, "concurrency": 5 }'

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("taroyamada/dns-dmarc-security-checker").call(run_input={
  "domains": ["google.com", "github.com", "example.com"],
  "checkDkim": true,
  "concurrency": 5
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('taroyamada/dns-dmarc-security-checker').call({
  "domains": ["google.com", "github.com", "example.com"],
  "checkDkim": true,
  "concurrency": 5
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Tips & Limitations

• Schedule weekly runs against your production domains to catch config drift.
• Use webhook delivery to pipe findings into your SIEM (Splunk, Datadog, Elastic).
• For CI integration, block releases on critical severity findings using exit codes.
• Combine with ssl-certificate-monitor for layered cert + headers coverage.
• Findings include links to official remediation docs — share with dev teams via the webhook payload.

FAQ

Is running this against a third-party site legal?

Passive public-header scanning is generally permitted, but follow your own compliance policies. Only scan sites you have authorization for.

How often should I scan?

Weekly for production domains; daily if you have high config-change velocity.

Can I export to a compliance tool?

Use webhook delivery or Dataset API — formats map well to Drata, Vanta, OneTrust import templates.

Is this a penetration test?

No — this actor performs passive compliance scanning only. No exploitation, fuzzing, or auth bypass.

Does this qualify as a SOC2 control?

This actor produces evidence artifacts suitable for SOC2 CC7.1 (continuous monitoring). It is not itself a SOC2 certification.
