Introduction
Web-based mail systems allow users to send, receive,
and manage emails via a web browser. Unlike traditional
email clients, web-based mail services require no
installation and provide accessibility on various devices
with internet connectivity. Examples include Gmail,
Yahoo Mail, and Outlook.com.
This project focuses on designing and implementing a
simplified web-based email system.
2
Objective
• To design a secure and user-friendly web-based mail system.
To enable basic functionalities like composing, sending,
receiving, and managing emails.
• To ensure data integrity and privacy using authentication
mechanisms.
To study and integrate networking protocols such as SMTP,
POP3, and IMAP

Scope of the project
*Inclusion:*
- User registration and login.
Sending and receiving emails.
- Inbox management (read, delete,archive).
*Exclusion:*
Advanced features like spam filtering, auto-responses, and Al integration.
- Large-scale deployment for millions of users.

System architecture
Illustrate a layered architecture with the following components:
*Presentation Layer: Browser-based interface.
*Application Layer*: Server handlingrequests and processing
emails.
*Database Layer*: storage of user information and email data.
Example Architecture S
Diagram: Include a labeled block diagram showing
communication between components using HTTP/HTTPS and
email protocols like SMTP and IMAP.
5
Features
• *User Authentication*: Secure login and registration.
*Email Composition*: Compose, , and attach files.
*Inbox Management: Read, archive, delete emails.
*Search Functionality*: Searcsendh for specific emails
by keywords
6
Technologies used
Frontend: HTML, CSS, JavaScript, React.js.
Backend: Node.js, Python (Django/ Flask), or PHP.
Database: MySQL or MongoDB.
Protocols: SMTP (for sending), IMAP/ POP3 (for receiving).
Other Tools: Bootstrap (for UI), Postman (for API testing).

System design and implementation
Frontend Design*
*Login and Registration Pages: User authentication interface.
*Inbox Page*: List emails with options to read, delete, or archive
Compose Mail Page*: Rich text editor and file attachment
options.P
Backend Design*
Authentication Module*: Validate user credentials using hashing
algorithms like b
.Email Handling Module*: Use SMTP for sending emails and
IMAP for retrieving them.
*APIs*: REST APIs for user management and email operations.
Database Design*
User Table*: Stores user details (e.g., user_id, username,
password, email).
Email Table*: Stores email metadata (e.g., email_id, sender,
receiver, subject, body,status) .
*Attachments Table*: Stores file metadata (e.g., attachment id,
file_path).
8
Testing and validation
*Unit Testing*: Test individual modules like user authentication,
email sending, and receiving.
*Integration Testing*: Ensure all components work together
seamlessly.
*User Testing*: Feedback on usability and interface design.
*Validation Results*: Include a table summarizing test cases,
expected vs. actual outcomes.

Challenges faced
Frontend: HTML, CSS, JavaScript, React.js.
Backend: Node.js, Python (Django/ Flask), or PHP.
Database: MySQL or MongoDB.
Protocols: SMTP (for sending), IMAP/ POP3 (for
receiving).
Other Tools: Bootstrap (for UI), Postman (for API
testing).
10
Future enhancement
*Spam Filtering: Implement Al-
based filtering algorithms.
Enhanced Search*: Allow
advanced filtering and
categorization.
Mobile Optimization*: Develop
mobile-friendly interfaces.
Integration*: Add calendar and
contact management features.

Conclusion
This microproject demonstrates the
basic functionality of a web-based
email system, providing a hands-on
approach to learning how web
applications interact with servers and
databases. While this system is a
simplified version of popular services
like Gmail, it covers core concepts
like user authentication, email
storage, and sending/receiving
emails. By completing this project,
one gains insight into the underlying
technologies of web-based email
services, which is a valuable skill for
web development.
