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

async function chilkatExample() {
  // This example assumes 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();

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

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

  // Set the ImmediateDelete property = false
  // When the DeleteEmail method is called, the POP3 session
  // will remain open and the emails will be deleted all at once
  // when the session closes.
  mailman.immediateDelete = false;

  // Download email headers.  
  const bundle = new EmailBundle();

    // If you decide the email is to be deleted, call DeleteEmail.
    // This marks the email for deletion on the POP3 server.
