Scalable Email Notification Authentication

As a Data Manager, I want the email notification system to support multiple authentication mechanisms (e.g., SMTP, TrueAPI), so that I can choose and configure the authentication method that best suits my needs and ensure seamless and secure email delivery for end users.

Acceptance Criteria:

1. The system allows configuration of multiple authentication mechanisms, including but not limited to SMTP and TrueAPI.
2. End users can select and switch between authentication methods based on their convenience.
3. The design supports future scalability to incorporate additional authentication mechanisms.
4. Comprehensive documentation is provided for configuring and managing different authentication options.
5. The solution ensures secure and reliable email delivery across all supported authentication methods.

Technical Notes:

• Design should support a plugin-based architecture for easy integration of new authentication mechanisms.
• Ensure backward compatibility with the existing SMTP-based system.
• Provide logging and error handling for each authentication mechanism.
