# Description A poorly named "Mailserver" is essentially a Whisper node that stores message history in either a LevelDB or PostgreSQL database. A Status app user can run their own Mailserver for faster message retrieval or additional security. # Service Ports * `30303` TCP - [DevP2P](https://github.com/ethereum/devp2p) wire protocol port. Should __ALWAYS__ be public. * `8545` TCP - [JSON RPC](https://github.com/ethereum/wiki/wiki/json-rpc) management port. Should __NEVER__ be public. # Setup methods This document describes the two alternative ways to start a Status Mailserver: * [Docker Compose](https://docs.docker.com/compose/) - More self-contained and portable * [Systemd Service](https://www.freedesktop.org/wiki/Software/systemd/) - More local and configurable ## Docker Compose The simplest way is to just use: ``` make run-mailserver-docker ``` This will generate the necessary config, compose and then start the container. For more details read the [README](_assets/compose/mailserver/README.md). ## Systemd Service The other way is to run the `mailserver` under `systemd`: ``` make run-mailserver-systemd ``` This will generate the necessary config, define and then start a user service. Use `sudo` if you want it to be a system service. For more details read the [README](_assets/systemd/mailserver/README.md).
