# Mailpot - WIP mailing list manager

Crates:

- `core`
- `cli` a command line tool to manage lists
- `rest-http` a REST http server to manage lists

## Project goals

- easy setup
- extensible through Rust API as a library
- extensible through HTTP REST API as an HTTP server, with webhooks
- basic management through CLI
- replaceable lightweight web archiver
- custom storage?
- useful for both newsletters, discussions

## Initial setup

Check where `mpot` expects your database file to be:

```shell
$ cargo run --bin mpot -- db-location
Configuration file /home/user/.config/mailpot/config.toml doesn't exist
```

Uuugh, oops.

```shell
$ mkdir -p /home/user/.config/mailpot
$ echo 'send_mail = { "type" = "ShellCommand", "value" = "/usr/bin/false" }' > /home/user/.config/mailpot/config.toml
$ cargo run --bin mpot -- db-location
/home/user/.local/share/mailpot/mpot.db
```

Now you can initialize the database file:

```shell
$ mkdir -p /home/user/.local/share/mailpot/
$ sqlite3 /home/user/.local/share/mailpot/mpot.db < ./core/src/schema.sql
```
