# WildDuck Mail Server
WildDuck uses a distributed database (sharded + replicated MongoDB) as a backend for storing all data, including emails. WildDuck tries to follow Gmail in product design. If there's a decision to be made then usually the answer is to do whatever Gmail has done. ## Links - [Website](https://wildduck.email) - [Documentation](https://docs.wildduck.email) - [Installation instructions](https://docs.wildduck.email/#/general/install) - [API Documentation](https://docs.wildduck.email/api) ## License WildDuck Mail Agent is licensed under the [European Union Public License 1.2](https://joinup.ec.europa.eu/collection/eupl/eupl-text-eupl-12) or later.
