mailpitter
Command-line tool for macOS and Linux
mailpitter is a command-line tool that runs one shared local Mailpit container and registers it with caddy_shack at mailpit.test, so every project on your machine sends mail to the same place. It installs, starts, stops, upgrades and diagnoses the container, registers each consumer project and prints the .env and docker-compose snippets it needs, and can reset the mail data when you want a clean slate. It works with Docker Desktop, OrbStack, Colima, Lima, Rancher Desktop and native Linux Docker.
