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.

Step 1: Navigate to Mail Server Settings

1. Log in to your ZeroThreat On-Prem portal
2. Go to Organization Settings

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

  Example: mail.yourdomain.com
• Port
  SMTP server port

• Username / Password
  Credentials used to authenticate with the SMTP server
• Secure (SSL/TLS)

  Enable this to reject self-signed or untrusted certificates

Save the configuration once all fields are correctly 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
