crates:

  • mailpot the core library

  • mailpot-archives static web archive generation or with a dynamic http server
  • mailpot-http a REST http server to manage lists

Features

  • easy setup
  • extensible through Rust API as a library
  • basic management through CLI tool
  • optional lightweight web archiver (static and dynamic)
  • useful for both newsletters, communities and for static article comments

Roadmap

  • extensible through HTTP REST API as an HTTP server, with webhooks

Initial setup

Create a configuration file and a database:

$ mkdir -p /home/user/.config/mailpot
$ export MPOT_CONFIG=/home/user/.config/mailpot/config.toml
$ cargo run --bin mpot -- sample-config > "$MPOT_CONFIG"
$ # edit config and set database path e.g. "/home/user/.local/share/mailpot/mpot.db"
$ cargo run --bin mpot -- -c "$MPOT_CONFIG" list-lists
No lists found.

This creates the database file in the configuration file as if you executed the following:

$ sqlite3 /home/user/.local/share/mailpot/mpot.db < ./core/src/schema.sql

    administrators: vec!["myaddress@example.com".to_string()],
};
let db = Connection::open_or_create_db(config)?.trusted();

// Create a new mailing list
let list_pk = db.create_list(MailingList {

    topics: vec![],
    archive_url: None,
})?.pk;
