Go-MailHog
=========

Inspired by [MailCatcher](http://mailcatcher.me/), easier to install.

Go-MailHog is a rewritten version of [MailHog](https://github.com/ian-kent/MailHog), which was born out of [M3MTA](https://github.com/ian-kent/M3MTA).

Go was chosen for portability - MailHog runs without installation on multiple platforms.

### Requirements

* None!

### Getting started

* Download the latest release of Go-MailHog for your platform
* Start MailHog

By default, the SMTP server will start on port 1025, and the HTTP
server will start on port 8025.

### Features

* ESMTP server implementing RFC5321
* Support for SMTP AUTH (RFC4954) and PIPELINING (RFC2920)
* Web interface to view messages (plain text, HTML or source)
* HTTP API to list, retrieve and delete messages
* Multipart MIME support
* In-memory message storage
* MongoDB storage for message persistence
* Lightweight and portable
* No installation required

(Tests currently fail using in-memory storage, use MongoDB!)
