SMTP is a protocol for sending emails. In this recipe, we will be setting up an SMTP server using a third-party npm module named smtp-server.

You probably receive several automated emails per day in your inbox. In the There’s more… section, we’re going to learn how we can send an email via Node.js to the SMTP server we created in the recipe.

$ mkdir server-smtp
$ cd server-smtp
$ touch server.js

$ npm init --yes
