ValidEmailChecker

ValidEmailChecker is a simple desktop application for checking if an email address is valid, disposable, and has valid DNS records. It uses a Python Tkinter GUI for the client and a small Node.js Express server as a backend. The backend queries the Disify email validation API.

Features

• Easy-to-use GUI: Just enter an email address and get instant feedback.
• Disposable email detection: Know if an email is from a disposable service.
• DNS check: See if the domain has valid DNS records.
• API-based validation: Uses the Disify API for accuracy.

How it Works

1. The user enters an email address in the desktop app.
2. The Python client sends a request to the local Node.js server.
3. The server fetches validation info from Disify and returns it to the client.
4. Results are displayed in the GUI in a friendly format.

Setup

1. Clone the Repository

git clone https://github.com/allenmonkey970/ValidEmailChecker.git
cd ValidEmailChecker

2. Start the Backend Server

The backend is written in Node.js.

cd ValidEmailChecker
npm install
node server.js

The server will start on http://localhost:5000.

3. Run the Python Client

Make sure you have Python 3 and pip installed.

Install dependencies:

pip install pillow requests

Run the client:

python client.py

Note: The logo.png file is required in the same directory as client.py for the GUI icon.

File Structure

• client.py – Python Tkinter GUI client.
• server.js – Node.js Express backend server.
• logo.png – App icon/logo.

Screenshots

Troubleshooting

• CORS Errors: The server uses CORS, but if you run into CORS issues, make sure the server is running before starting the client.
• Connection Errors: Ensure the backend server is running on localhost:5000 before launching the client.
• Logo Issues: If you get an error related to logo.png, make sure the image exists in the same folder as client.py.
