Usage

Load the nodemailer-smime plugin

const smime = require('nodemailer-smime');

Attach it as a 'stream' handler for a nodemailer transport object

transporter.use('stream', htmlToText(options));

Options

• cert - PEM formatted SMIME certificate to sign/bundle mail with
• chain - array of PEM formatted certificates to bundle
• key - PEM formatted private key associated with certificate

Example

const nodemailer = require('nodemailer');
const smime = require('nodemailer-smime');
const transporter = nodemailer.createTransport();
const options = {
    cert: '<PEM formatted cert>',
    chain: [
      '<PEM formatted cert>'
    ],
    key: '<PEM formatted key>'
}
transporter.use('stream', smime(options));
transporter.sendMail({
    from: 'me@example.com',
    to: 'receiver@example.com',
    html: '<b>Hello world!</b>'
});
