Here is an example of a simple Java-based web email client using JavaMail:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class EmailClient {
    public static void main(String[] args) {
        // Set up email settings
        String host = "smtp.gmail.com";
        String port = "587";
        String username = "[email protected]";
        String password = "your_password";

        // Create a session
        Properties props = new Properties();
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.port", port);
        props.put("mail.smtp.auth", "true");
        Session session = Session.getInstance(props, new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        });

        // Create a message
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(username));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        message.setSubject("Test Email");
        message.setText("This is a test email");

        // Send the message
        Transport.send(message);

        // Receive email
        Store store = session.getStore();
        Folder folder = store.getFolder("INBOX");
        Message[] messages = folder.getMessages();
        for (Message msg : messages) {
            System.out.println(msg.getSubject());
        }
    }
}

This example demonstrates how to send and receive email using JavaMail. You can modify the code to suit your specific needs and add additional features such as email filtering, spam filtering, and virus scanning.
