# MX, SPF and DMARC checker for a list of domains

**Use case:** 

Audit the mail setup of any list of domains: MX hosts and mailbox provider, the SPF record and its all qualifier, the DMARC record and its p= policy, and whether MTA-STS is published. Preconfigured for domains rather than addresses, so you get one row per domain.

## Input

```json
{
  "emails": [],
  "domains": [
    "stripe.com",
    "apify.com",
    "nvidia.com",
    "rippling.com"
  ],
  "checkSpfDmarc": true,
  "treatDisposableAsInvalid": true,
  "treatRoleAddressAsRisky": true,
  "deduplicate": true,
  "onlyStatuses": [],
  "concurrency": 10,
  "dnsTimeoutSeconds": 5,
  "dnsResolvers": [
    "1.1.1.1",
    "8.8.8.8",
    "9.9.9.9"
  ]
}
```

## Output

```json

  "domain": {
    "label": "Domain",
    "format": "string"
  },

## About this Actor

This example demonstrates how to use [Bulk Email Verifier - MX, SPF, DMARC & Disposable](https://apify.com/thedeadpoet/bulk-email-verifier-mx-spf-dmarc-disposable-check.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/thedeadpoet/bulk-email-verifier-mx-spf-dmarc-disposable-check.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
