NTLM authentication for Nodemailer

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',
