[exim] Sample Frontend Javascript Code

Hi everyone,

I'm searching for a sample inbound front-end javascript authenticator to
transfer Cloudflare worker email messages (
https://developers.cloudflare.com/email-routing/email-workers/) to my
backend Exim imap.cfored.com mail server.

Here is my working front-end Javascript code:

// Define the readResponse function
async function readResponse(client) {
  return new Promise((resolve, reject) => {
    let response = "";
    // Simulate the event-based nature of Node.js
    // This is a simplified simulation and may not cover all use cases
    // In a real browser environment, you would use the Fetch API or other
appropriate APIs
    setTimeout(() => {
      // Simulate receiving data
      const data = "Simulated response data";
      response += data;
      if (response.endsWith("\r") || response.endsWith("\n") ||
response.endsWith("\r\n")) {
        resolve(response);
      }
    }, 1000); // Simulate 1 second delay
  });
}

// Define the EmailForwarder class
class EmailForwarder {
  async handleRequest(event) {
    // Update the SMTP relay server information
    const relayServer = "imap.cfored.com";
    const relayPort = 10025;

    // Rest of the method remains unchanged

    // Simulate connecting to the SMTP relay server
    // In a real browser environment, you would use the Fetch API or other
appropriate APIs
    const client = {
      send: (emailData) => {
        // Simulate sending the email
        console.log("Sending email:", emailData);
      }
    };

    // Simulate waiting for the response from the server
    const response = await readResponse(client);

    // Handle the response
    // ...

    // Simulate returning the response
    console.log("Email sent successfully");
  }
}

// Define the formatEmail function to convert webhook data to SMTP message
format
function formatEmail(data) {
// Implement logic to generate the SMTP message based on your format needs
// This is a placeholder, replace with your actual implementation
return `From: ${data.from}\r\nTo: ${data.to}\r\nSubject:
${data.subject}\r\n\r\n${data.body}\r\n`;
}
