### Issue

**Email notifications are not working because no SMTP host is configured on the run.**

To enable email notifications, configure the SMTP settings under **FIRE UI → Configurations**.

### Prerequisites

Before configuring SMTP, collect the following details from the customer/IT team:

- SMTP Host
- SMTP Port
- SMTP Username
- SMTP Password
- Mail From email address
- SMTP authentication requirement
- Encryption type — TLS/STARTTLS/SSL

For example, for a Microsoft 365 SMTP setup:

| Parameter | Example |
| --- | --- |
| **Mail From** | `support@sparkflows.io` |
| **SMTP Host** | `smtp.office365.com` |
| **SMTP Port** | `25` |
| **SMTP Auth User** | `support@sparkflows.io` |
| **SMTP Auth Password** | SMTP account password |
| **Encryption** | Confirm with the customer’s Microsoft 365 administrator |

> **Security:** Do not commit the SMTP password or any other credentials to Git. Use the FIRE UI configuration/secret-management mechanism to store sensitive values.

## Steps to Configure SMTP

### 1. Open FIRE UI

Log in to the **FIRE UI** application using an account with permission to modify system configurations.

### 2. Navigate to Configurations

Go to:

**FIRE UI → Configurations**

Locate the **ALERT** configuration section.

### 3. Configure Mail From

Locate:

`alert.mailFrom`

Set it to the email address that should appear as the sender.

Example:

```auto
support@sparkflows.io

```

### 4. Configure SMTP Host

Locate:

`alert.mailSmtpHost`

Set the SMTP server hostname.

Example:

```auto
smtp.office365.com

```

### 5. Configure SMTP Port

Locate:

`alert.mailSmtpPort`

Set the SMTP server port.

Example:

```auto
25

```

The port should be provided/approved by the customer’s email administrator. For Microsoft 365 authenticated SMTP submission, **587 with STARTTLS** is also commonly used.

### 6. Configure SMTP Authentication User

Locate:

`alert.mailSmtpAuthUser`

Enter the SMTP authentication username.

Example:

```auto
support@sparkflows.io

```

### 7. Configure SMTP Authentication Password

Locate:

`alert.mailSmtpAuthPassword`

Enter the password associated with the SMTP authentication account.

```auto
<SMTP_PASSWORD>

```

**Do not add the actual password to the Git documentation.**

### 8. Save the Configuration

After entering all required values, save/update the configuration.

Verify that the values are displayed correctly. The SMTP password should remain masked.

### 9. Test Email Notification

Trigger a workflow/run that generates an email notification.

Verify:

- The run completes successfully.
- The email notification is generated.
- The email is received by the intended recipient.
- The **From** address is correct.
- There are no SMTP authentication or connection errors in the application logs.
