Mail Server Configuration

Introduction

Mail server configuration allows ZeroThreat to send operational and system-related notifications from your On-Prem deployment. These notifications help teams stay informed about scan activity and administrative events.

Common email notifications include:

• Scan start and completion alerts
• Organization member invitations
• System-generated notifications and status updates

Mail settings are configured at the organization level.

Configure Mail Server

Step 1: Navigate to Mail Server Settings

1. Log in to your ZeroThreat On-Prem portal
2. Go to Organization Settings
3. Select Mail Server Configuration

Step 2: Configure Mail Server Fields

Fill in the following fields based on your SMTP server details:

• From
  Email address used as the sender
  Example: alerts@yourdomain.com
• Host
  SMTP server hostname
  Example: mail.yourdomain.com
• Port
  SMTP server port
  Example: 465 or 587
• Username / Password
  Credentials used to authenticate with the SMTP server
• Secure (SSL/TLS)
  Enable this if your SMTP server requires a secure connection
• TLS Reject Unauthorized
  Enable this to reject self-signed or untrusted certificates

Save the configuration once all fields are filled.

Common Mail Issues

Many enterprise mail servers block outbound emails to external domains.
If emails are not received:

• Verify SMTP credentials
• Check firewall and mail relay rules
• Confirm that the SMTP server allows external delivery
