nodemailer-ntlm-auth

Nodemailer 5+ allows to use custom authentication mechanisms. While there is no support in Nodemailer for NTLM then it can be provided with an addon.

NB! Experimental! Might not work as advertised due to the lack of not being actually able to use any real NTLM capable server

Install

Requires Nodejs v8.0.0 or newer

npm install nodemailer-ntlm-auth

Usage

const nodemailer = require('nodemailer');
const nodemailerNTLMAuth = require('nodemailer-ntlm-auth');

let transporter = nodemailer.createTransport({
    host: 'smtp.example.com',
    port: 465,
    secure: true,
    auth: {
        type: 'custom',
        method: 'NTLM',
        user: 'username',
        pass: 'verysecret',
        options: {
            domain: 'my-domain',
            workstation: 'my-desktop'
        }
    },
    customAuth: {
        NTLM: nodemailerNTLMAuth
    }
});

transporter.sendMail({
    from: 'sender@example.com',
    to: 'recipient@example.com',
    subject: 'hello world!',
    text: 'hello!'
}, console.log)
