# Custom SMTP

> Send ChatOps emails from your own domain

The Custom SMTP integration allows you to send ChatOps emails through your own SMTP server. This makes emails appear from your company domain (e.g., `security@yourcompany.com`) instead of Wirespeed's default email infrastructure.

<Info>
  When Custom SMTP is installed, it automatically replaces the default [Email](/integrations/email) integration for all ChatOps communications.

## Configuration

To set up the integration, go to Integrations > [**Add Integration**](https://app.wirespeed.co/settings/integrations?tab=browse) > **Custom SMTP** and provide the following:

| Field                  | Description                                                 |
| ---------------------- | ----------------------------------------------------------- |
| **SMTP Host**          | Your SMTP server hostname (e.g., `smtp.office365.com`)      |
| **SMTP Port**          | Port number. Use `587` for STARTTLS or `465` for SSL/TLS    |
| **Use SSL/TLS**        | Optional. If not set, automatically detected based on port  |
| **From Email Address** | The sender email address (e.g., `security@yourcompany.com`) |
| **From Name**          | Display name for the sender (e.g., `Security Team`)         |
| **SMTP Username**      | Authentication username for your SMTP server                |
| **SMTP Password**      | Authentication password for your SMTP server                |

<Warning>
  Your SMTP credentials are validated when you install or enable the integration. If validation fails, the integration will remain disabled and an error will be logged.
</Warning>
