Email testing tool for developers that captures SMTP mail and shows it in a web interface with a JSON API.

STUB. This software has no release or pre-release in four years, or its project site no longer shows it, so it is not part of the register, not counted and not indexed. It will be checked again.

## Notes

MailHog is an email testing tool for developers. It is a Go program that runs an SMTP server with a web interface for viewing captured messages and an HTTP API. The [README](https://github.com/mailhog/MailHog/blob/master/README.md) lists installs through Homebrew, go install, FreeBSD packages, Docker and release binaries, and its overview says applications are configured to use MailHog for SMTP delivery. The deployment guide says it can run locally from the command line or be started as a daemon. The README names MongoDB and file-based storage as options for keeping captured messages.
