I'm working with meteor on an ubuntu install and I was getting similar errors after upgrading to Node.js v12.0 and installing Meteor's accounts-password module.

Turned out, since Meteor has not yet begun development on compatibility with Node.js v12.0, the new binaries installed with Node on my server were not compatible with the binaries bundled with my deployment so I was getting similar errors. In this case, the problem was not with Nodemailer but with simplesmtp.

As suggested here, the solution was to remove the bundled version and use npm to install a server-local version.

So in my deployment script, I added the following lines after I built the bundle.

cd bundle/programs/server/
sudo rm -R ./npm/npm-bcrypt/node_modules/bcrypt
sudo npm install bcrypt
sudo rm -R ./npm/email/node_modules/simplesmtp
sudo npm install simplesmtp

This is easier than modifying the source, especially if you have a scripted deployment.
