Go-MailHog

Inspired by MailCatcher, easier to install.

Go-MailHog is a rewritten version of MailHog, which was born out of M3MTA.

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

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.

You can configure Go-MailHog using command line options:

Parameter	Default	Description
-hostname	mailhog.example	Hostname to use for EHLO/HELO and message IDs
-httpbindaddr	0.0.0.0:8025	Interface and port for HTTP server to bind to
-mongocoll	messages	MongoDB collection name for message storage
-mongodb	mailhog	MongoDB database name for message storage
-mongouri	127.0.0.1:27017	MongoDB host and port

Clone this repository to $GOPATH/src/github.com/ian-kent/MailHog and type go install.

You'll need go-bindata to embed web assets:

go get https://github.com/jteeuwen/go-bindata/...
go-bindata assets/...

If you build using make install, necessary dependencies will be installed for you.

Run tests using make test. You'll need a copy of MailHog running for tests to pass. (Tests currently fail using in-memory storage, use MongoDB!)

If you make any changes, run go fmt before submitting a pull request.
