SMTP NTLM Authentication

See more SMTP Examples

Demonstrates how to specify NTLM authentication for sending email via SMTP. React Native

import { Email, 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.

  const mailman = new MailMan();

  // Specify your particular mail server's SMTP settings.
  mailman.smtpHost = 'smtp.my_mail_server.com';
  mailman.smtpPort = 587;
  mailman.startTLS = true;

  // This assumes you know your SMTP server supports NTLM authentication.
  // To explicitly request NTLM authentication, set the SmtpAuthMethod property = "ntlm".
  mailman.smtpAuthMethod = 'ntlm';

  // Note: Normally you should avoid setting the SmtpAuthMethod.
  // SMTP servers tell the connecting client the authentication methods it will accept when the initial connection is made.
  // Chilkat will automatically use this information to select and use the most secure auth method supported by the server.

  const useCurrentWindowsUser = true;

  if (useCurrentWindowsUser) {
    // If you are running on Windows, and you wish for the NTLM credentials of the current logged-on Windows user to be used,
    // set the username and password to the string "default"
    mailman.smtpUsername = 'default';
    mailman.smtpPassword = 'default';
  } else {
    // Explicitly specify the SMTP username/password
    // The SMTP username is your email account username, which is often your email address.
    mailman.smtpUsername = 'your_smtp_username_or_email_address';
    mailman.smtpPassword = 'your_password';
  }

  const email = new Email();

  email.subject = 'This is a test';
  email.body = 'This is a test';
  // Don't forget to change this to use your email addresses..
  email.from = 'Chilkat Support <support@chilkatsoft.com>';
  email.addTo('Chilkat Admin', 'admin@chilkatsoft.com');
  // To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

  try {
    await mailman.sendEmailAsync(email);
  } catch {
    console.log(mailman.lastErrorText);
    return;
  }

  try {
    await mailman.closeSmtpConnectionAsync();
