# Check SSL certificates of mail servers (IMAP, SMTP)

**Use case:** 

Checks the TLS certificate served on mail ports (993 for IMAP, 465 for SMTP): validity, expiry, issuer and hostname match. Not only websites: any host and port.

## Input

```json
{
  "hosts": [
    "imap.gmail.com:993",
    "smtp.gmail.com:465",
    "outlook.office365.com:993"
  ],
  "expiryWarningDays": 30
}
```

## Output

```json
{
  "host": {
    "label": "Host"
  },
  "port": {
    "label": "Port",
    "format": "number"
  },
  "valid": {
    "label": "Valid",
    "format": "boolean"
  },
  "daysToExpiry": {
    "label": "Days to expiry",
    "format": "number"
  },
  "expiresSoon": {
    "label": "Expires soon",
    "format": "boolean"
  },
  "issuer": {
    "label": "Issuer"
  },
  "validTo": {
    "label": "Expires",
    "format": "date"
  },
  "protocol": {
    "label": "TLS"
  },
  "error": {
    "label": "Problem"
  }
}
```

### 3. Receive the "Check SSL certificates of mail servers (IMAP, SMTP)" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as host, port, valid, and more.

### 4. Integrate into your workflow

## 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/propped_cloak/ssl-certificate-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`).
