## Notes

Inbucket is an email testing server. It accepts mail for any address over SMTP, stores each message as a file on disk, and shows the messages in a web interface with REST and POP3 access. Applications send their mail to its built-in SMTP server, and developers read the result in the browser. It is written in Go, and the project's pages describe running it as a daemon, from a compiled binary or from a Docker image.

## Worth knowing

The project calls itself an [email testing application](https://inbucket.org), written for web developers who want to see the emailed output of their applications.
