Fake SMTP server that doesn't deliver the received mails. Useful for debugging and testing apps that send email.


Tired of accidentally sending test mails from your development environment to real addresses?

Meet /mail/null, a dummy SMTP server for development. Instead of relaying messages it renders them in a simple web interface for easy browsing.

npm install -g mail-null

The server listens for connections on port 2525 (SMTP) and 3000 (HTTP). This can be overridden by setting the environment variables SMTP_PORT and PORT.
