Add Support for Multiple Mailbox Connections with Object-Level Permission Access

[sepehr-akbarzadeh]

Overview:
Currently, the mailbox client supports a single mailbox connection per user or instance. To enhance flexibility and security, we propose adding a feature to support multiple mailbox connections with granular, object-level permission access. This feature will enable users to manage multiple email accounts and control access to individual mailboxes or folders based on specific permissions.

Proposed Features:

1. Multiple Mailbox Connections:

   • Allow users to configure and connect to multiple mailboxes within a single application instance.
   • Provide an interface in the settings to add, remove, and manage multiple mailbox connections.

2. Object-Level Permissions:

   • Implement a permissions system to control access to mailboxes and their contents at an object level (e.g., folders, individual emails).
   • Define roles and permissions (e.g., read, write, delete) for each mailbox or folder.
   • Support permissions for different user roles or groups.

3. Permission Management Interface:

   • Add an interface to the admin panel or settings where administrators can configure permissions for each mailbox, folder, or email.
   • Allow for detailed permission settings such as who can view, edit, or delete emails and folders.

4. Access Control Logic:

   • Implement logic to enforce permissions when users access mailboxes, folders, or individual emails.
   • Ensure that permissions are correctly applied and that unauthorized access is prevented.

5. User and Role Management:

   • Integrate with existing user and role management systems to assign permissions.
   • Provide options for assigning permissions to specific users or groups.

6. Database Schema Changes:

   • Update the database schema to support multiple mailboxes and object-level permissions.
   • Create and run migration scripts to apply schema changes.

7. Documentation:

   • Update documentation to include information on configuring and managing multiple mailboxes and permissions.
   • Provide examples and usage guidelines for setting up and managing access control.

Benefits:

• Provides users with the ability to manage multiple email accounts from a single application instance.
• Enhances security by allowing granular control over who can access specific mailboxes or folders.
• Improves flexibility and organization by supporting various mailbox configurations and permissions.

Potential Challenges:

• Ensuring the security and accuracy of object-level permissions.
• Handling potential performance impacts with multiple mailbox connections.
• Updating existing data models and schemas without causing disruptions.

Additional Context:
Adding support for multiple mailbox connections with object-level permission access will significantly enhance the functionality and security of the mailbox client. This feature is crucial for users who manage multiple email accounts or require fine-grained control over email access.

Tasks:

1. Design and implement support for multiple mailbox connections.
2. Develop and integrate object-level permission management.
3. Update the database schema and run migrations.
4. Create a user interface for managing mailboxes and permissions.
5. Implement access control logic and test thoroughly.
6. Update documentation and provide examples.
