Mailpit SMTP Testing and Email Capture Workbench

This skill uses Mailpit as a safe SMTP sink for development, QA, and automated test runs. It helps teams capture, inspect, search, and validate transactional email without sending anything to real inboxes.

Installation

Use the upstream install or setup path that matches your environment:

• If installed using homebrew, you may run brew services start mailpit to always run mailpit automatically.

Requirements and caveats from upstream:

• <a href="https://github.com/axllent/mailpit/actions/workflows/build-docker.yml"><img src="https://github.com/axllent/mailpit/actions/workflows/build-docker.yml/badge.svg" alt="CI Docker build status"></a>
• <a href="https://hub.docker.com/r/axllent/mailpit"><img src="https://img.shields.io/docker/pulls/axllent/mailpit.svg" alt="Docker pulls"></a>
• Runs entirely from a single static binary or multi-architecture Docker images

Basic usage or getting-started notes:

• Modern web UI with advanced mail search to view emails (formatted HTML, highlighted HTML source, text, headers, raw source, and MIME attachments

• Real-time web UI updates using web sockets for new mail & optional browser notifications when new mail is received
