SMTP Settings - CRM6.2P1US6.2

1. Problem Statement

User Roles Identified

• System Admin (IT Director): Responsible for IT infrastructure, security protocols, and system configurations
• Utility Administrator: Primary SMART360 system administrator managing system settings and configurations

Pain Points by User Role

System Admin (IT Director):

• Difficulty in managing email delivery configurations across multiple utility systems
• Lack of centralized SMTP configuration management causing security vulnerabilities
• Unable to implement consistent email authentication protocols across all systems
• Time-consuming manual configuration of email settings for each system component
• Insufficient visibility into email delivery performance and failure rates

Utility Administrator:

• Complex email configuration requirements that require IT expertise
• Inability to test email configurations before implementing in production
• Difficulty troubleshooting email delivery issues without technical knowledge
• Manual process to configure different email providers for various system notifications
• Risk of system downtime due to incorrect email configurations

Core Problem

The utility lacks a centralized, user-friendly interface for configuring and managing SMTP email settings across the SMART360 system, leading to inconsistent email delivery, security vulnerabilities, and operational inefficiencies.

2. Who Are the Users Facing the Problem?

System Admin (IT Director):

• Oversees all IT infrastructure and security protocols
• Manages system integrations and vendor configurations
• Ensures compliance with cybersecurity standards
• Should have full access to all SMTP configuration features

Utility Administrator:

• Primary system administrator for SMART360
• Manages system settings and business process configurations
• Coordinates between IT and business departments
• Should have access to basic SMTP configuration with IT approval for security-sensitive settings

3. Jobs To Be Done

For System Admin (IT Director): When I need to configure secure email delivery settings for the SMART360 system, But I currently manage multiple disconnected email configurations across different system components with limited visibility into delivery performance, Help me centralize SMTP configuration management with comprehensive security controls and monitoring capabilities, So that I can ensure reliable email delivery while maintaining cybersecurity standards and reducing administrative overhead.

For Utility Administrator: When I need to set up email notifications and system communications for business processes, But I struggle with complex technical email configurations that require IT expertise and cannot easily test settings before deployment, Help me configure email settings through an intuitive interface with guided setup and testing capabilities, So that I can ensure business-critical notifications are delivered reliably without depending on IT for routine configuration changes.

4. Solution

The SMTP Settings Configuration module provides a comprehensive email configuration management system that enables secure, reliable email delivery for all SMART360 system communications.

• Failed delivery alerts and notifications

5. Major Steps Involved

Step 1: Access Configuration Interface

• Navigate to Settings menu from main navigation
• Click on "SMTP" from settings submenu
• System displays SMTP Settings page with "Configure your SMTP server settings for email delivery" header
• User sees empty configuration form if no existing setup

Step 2: Basic Server Configuration

• Click in "Host" field (currently showing placeholder "smtp.example.com")
• Enter email provider's SMTP server address (e.g., "smtp.gmail.com")
• System validates domain format in real-time
• Navigate to "Port" field (shows default "587")
• Use increment/decrement buttons or manually enter port number
• System highlights if non-standard port is selected

Step 3: Authentication Setup

• Click "Auth Protocol" dropdown (currently showing "LOGIN")
• Select appropriate protocol: LOGIN, PLAIN, or CRAM-MD5
• System displays protocol description tooltip
• Enter username in format "user@example.com" in Username field
• Click Password field and enter secure credentials
• System masks password input with dots

Step 4: Provider and Security Configuration

• Click "Email Provider" dropdown (showing "Select email provider")
• Choose from list: Gmail, Office 365, Yahoo, Custom, etc.
• System auto-populates recommended settings if provider template selected
• Configure "HELO Hostname" (defaults to "localhost")
• Click "TLS" dropdown and select "STARTTLS" (recommended option shown)
• System displays encryption description: "TLS/SSL encryption; STARTTLS is commonly used"

Step 5: Connection Management

• Review "Max Connections" field (default "10")
• Use increment/decrement or enter custom value based on email volume needs
• Set "Retries" count (default "3") for failed delivery attempts
• Configure "Idle Timeout" (default "30s") for connection cleanup
• Set "Wait Timeout" (default "30s") for response waiting

Step 6: Advanced Configuration

• Click in "Custom Headers" text area
• Add custom headers in format "X-Custom-Header: value"
• Example entries: ---

X-Mailer: SMART360-System
X-Priority: 1
X-Source: UtilityNotifications

• Each header on separate line following RFC 2822 format

Step 7: Configuration Testing

• Click "Test Connection" button at bottom of form
• System displays loading indicator "Testing connection..."
• Wait for test results (typically 5-15 seconds)
• Success Path: Green checkmark with "Connection successful" message
• Failure Path: Red error icon with specific error message like:
  • "Authentication failed - check credentials"
  • "Connection timeout - verify host and port"
  • "TLS handshake failed - check encryption settings"

Step 8: Error Resolution (if test fails)

• Review error message for specific issue
• Common fixes:
  • Verify host server address spelling
  • Check if port is blocked by firewall
  • Confirm username/password accuracy
  • Validate authentication protocol compatibility
• Modify configuration based on error type
• Re-run "Test Connection" until successful

Step 9: Configuration Activation

• Once test passes, click "Save" button
• System validates all required fields are completed
• Configuration is saved with current timestamp
• Toggle "Active" switch to ON position (top right)
• System displays confirmation: "SMTP configuration activated successfully"

Step 10: Verification and Monitoring

• System sends test email to admin's email address
• Check inbox for delivery confirmation
• Monitor system notifications for any delivery issues
• Access email delivery logs from monitoring dashboard
• Set up alerts for authentication failures or connection issues

Alternative Flows:

Modify Existing Configuration:

• If configuration exists, form pre-populates with current values
• User can modify any field while maintaining others
• System highlights changed fields for review
• Test connection validates only modified components
• Save updates existing configuration rather than creating new

Multiple Provider Setup:

• Click "Add New" button to create additional SMTP configuration
• System opens new configuration panel
• Complete same steps for secondary provider (backup/failover)
• Only one configuration can be active at a time
• Switch between configurations using provider dropdown

Error Handling:

• Network Issues: Display "Connection timeout" with retry option
• Invalid Credentials: Show "Authentication failed" with credential reset link
• Port Blocking: Alert "Port may be blocked" with alternative port suggestions
• Invalid Format: Highlight fields with format errors in red
• Unsaved Changes: Warn user before leaving page with unsaved modifications

Post-Conditions:

• SMTP configuration is successfully saved and activated
• Test email delivery confirms functionality
• System can send notifications and alerts via configured SMTP
• Admin receives confirmation of successful setup
• Configuration is logged in system audit trail

Success Metrics:

• Configuration completed without IT support ticket
• Test connection passes on first or second attempt
• Email delivery begins working immediately after activation
