Go-MailHog [ ![Download](https://api.bintray.com/packages/ian-kent/generic/Go-MailHog/images/download.svg) ](https://bintray.com/ian-kent/generic/Go-MailHog/_latestVersion)
=========
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
Either:
* [Download the latest release](RELEASES.md) of Go-MailHog for your platform
* Use Docker or AWS Elastic Beanstalk to deploy Go-MailHog with the example [Dockerfile](Dockerfile)
By default, the SMTP server will start on port 1025, the HTTP server will start
on port 8025, and in-memory message storage will be used.
### Features
* ESMTP server implementing RFC5321
* Support for SMTP AUTH (RFC4954) and PIPELINING (RFC2920)
* Web interface to view messages (plain text, HTML or source)
* Supports RFC2047 encoded headers
* Real-time updates using EventSource
* Release messages to real SMTP servers
* HTTP API to list, retrieve and delete messages
* See [APIv1 documentation](APIv1.md) for more information
* Multipart MIME support
* Download individual MIME parts
* In-memory message storage
* MongoDB storage for message persistence
* Lightweight and portable
* No installation required
