Enron Mail Server - GraphQL server exercise

The Enron scandal, publicized in October 2001, eventually led to the bankruptcy of the Enron Corporation, an American energy company based in Houston, Texas, and the de facto dissolution of Arthur Andersen, which was one of the five largest audit and accountancy partnerships in the world. In addition to being the largest bankruptcy reorganization in American history at that time, Enron was cited as the biggest audit failure Wikipedia (https://en.wikipedia.org/wiki/Enron_scandal)

In this excercise your task is to build a email server for storing Enron-emails.

You can choose your tooling pretty freely but the API should have following methods or ways to accomplish these tasks (at root level):

• Show all emails received by single user, recognized by email-address. ie. mailboxOf([email protected]) { .. }
