Selfhosted reimplementation of the Mailspring API

Free reimplementation of the Mailspring Sync backend (and other required APIs). This project aims to provide an alternative sync server that can be self hosted for the Mailspring Email Client.

🔴IMPORTANT🔴 Currently this project can only be used with my fork of the MailSpring Client since the official version doesn't allow changing the API URL.
