How to solve CERT_UNTRUSTED error in nodemailer

Question

I am trying to send an email with nodemailer. I already managed to send it from another host but now I want to send emails from another address. These are the versions of nodemailer I am using (from my package.json):

"nodemailer": "1.3.4",
"nodemailer-smtp-transport": "1.0.2",

This is the information I have about my webmail:

I set up nodemailer like this:

    var transport = nodemailer.createTransport(smtpTransport({
        host: 'securemail.linevast.de',
        port: 465,
        secure: true,
        auth: {
            user: '[email protected]', // this is my login name
            pass: 'mypassword'
        },
        maxConnections: 5,
        maxMessages: 10
    }));

And when I try to send an email I get the following error message.

[Error: certificate not trusted] code: 'CERT_UNTRUSTED'

The website is verified by GeoTrust Inc so I believe it is quite trustworthy. Is there a way to make nodemailer trust the certificate or force it to send the email even though it does not trust it?

Thank you for your help!

Yes, you can tell nodemailer to not check the certificate trust.

This is the option:

tls: {rejectUnauthorized: false}

use it on the initial transport object:

var transporter = nodemailer.createTransport(smtpTransport('SMTP',{
        host: 'mail.mailserver.com',
        port: 587,
        auth: {
            user: '[email protected]',
            pass: 'passwd'
        },            
        authMethod:'NTLM',
        secure:false,
        // here it goes
        tls: {rejectUnauthorized: false},
        debug:true
    })
);
