Building from Source

You will need a functioning Go installation for this to work.

Grab the Inbucket source code and compile the daemon:

go get -v

Edit etc/inbucket.conf and tailor to your environment. It should work on most Unix and OS X machines as is. Launch the daemon:

$GOPATH/bin/inbucket $GOPATH/src/

By default the SMTP server will be listening on localhost port 2500 and the web interface will be available at localhost:9000.
