React Native Requires Chilkat v11.0.0+

SOCKS4, SOCKS5 Proxy for POP3

Demonstrates how to communicate with a POP3 server through a SOCKS4 or SOCKS5 proxy. React Native

import { Email, EmailBundle, MailMan } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // The mailman object is used for receiving (POP3) 
  // and sending (SMTP) email.
  const mailman = new MailMan();

  // To use a SOCKS4 or SOCKS5 proxy, simply set the following
  // properties prior to making any calls that communicate with
  // a POP3 server:
  // The SOCKS hostname may be a domain name or 
  // IP address:
  mailman.socksHostname = 'www.mysocksproxyserver.com';
  mailman.socksPort = 1080;
  mailman.socksUsername = 'myProxyLogin';
  mailman.socksPassword = 'myProxyPassword';
  // Set the SOCKS version to 4 or 5 based on the version
  // of the SOCKS proxy server:
  mailman.socksVersion = 5;
  // Note: SOCKS4 servers only support usernames without passwords.
  // SOCKS5 servers support full login/password authentication.

  // Set the POP3 server's hostname
  mailman.mailHost = 'pop.example.com';

  // Set the POP3 login/password.
  mailman.popUsername = 'myLogin';
  mailman.popPassword = 'myPassword';

  // Copy the all email from the user's POP3 mailbox 
  // into a bundle object.  The email remains on the server.
  const bundle = new EmailBundle();
  const keepOnServer = true;
  const headersOnly = false;
  // Irrelevent because we are NOT downloading headers-only
  const numBodyLines = 0;
  try {
    await mailman.fetchAllAsync(keepOnServer, headersOnly, numBodyLines, bundle);
  } catch {
    console.log(mailman.lastErrorText);
    return;
  }

  const email = new Email();
  let i = 0;
  while (i < bundle.messageCount) {
    bundle.emailAt(i, email);

    console.log(`From: ${email.from}`);
    console.log(`Subject: ${email.subject}`);
    i++;
  }

  await mailman.pop3EndSessionAsync();
