# Monitor client domains for DNS email changes

**Use case:** 

Weekly audit for an MSP or IT team. Checks SPF, DKIM, DMARC and MX of your client domains, remembers the previous state and outputs only new or changed domains. Use it with a schedule to catch broken SPF (over 10 lookups) or a weakened DMARC policy before mail bounces.

## Input

```json
{
  "domains": [
    "stripe.com",
    "github.com",
    "example.org"
  ],
  "dkimSelectors": [],
  "checkCommonDkimSelectors": true,
  "monitorChanges": true,
  "onlyChanges": true,
  "monitorName": "msp-clients",
  "maxConcurrency": 8
}
```

## Output

```json
{
  "domain": {
    "label": "Domain",
    "format": "string"
  },
  "grade": {
    "label": "Grade",
    "format": "string"
  },
  "score": {
    "label": "Score",
    "format": "integer"
  },
  "spfAllQualifier": {
    "label": "SPF all",
    "format": "string"
  },
  "spfDnsLookups": {
    "label": "SPF lookups",
    "format": "integer"
  },
  "dmarcPolicy": {
    "label": "DMARC policy",
    "format": "string"
  },
  "dmarcRua": {
    "label": "DMARC rua",
    "format": "array"
  },
  "dkimSelectorsFound": {

  },
  "mxProvider": {

  "bimiRecord": {

  "changed": {
    "label": "Changed",
    "format": "boolean"
  },
  "recommendations": {
    "label": "Fixes",
    "format": "array"
  }
}
```

## About this Actor

This example demonstrates how to use [SPF, DKIM & DMARC Checker: Bulk Domain Email Auth Audit](https://apify.com/actose/email-dns-auth-checker.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/actose/email-dns-auth-checker.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/actose/email-dns-auth-checker.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
