PineMail

PineMail is a lightweight, self-hosted SMTP mail catcher designed for development environments. Point your application's mailer to localhost:1025 and every email your app sends during development gets captured, parsed, and displayed in a clean web UI at localhost:8025—without leaving your network.

Written in Rust and built with AI-agent-driven testing in mind, PineMail serves as a developer-friendly alternative to cloud-based services like Mailtrap or Mailpit. It provides local email inspection for testing workflows in isolated development environments.
