+## Running the test suite

+To run the integration tests, you need to have [GreenMail
+running](http://www.icegreen.com/greenmail/#deploy_docker_standalone). The
+easiest way to do that is with Docker:
+
+```console
+$ docker pull greenmail/standalone:1.5.8
+$ docker run -t -i -e GREENMAIL_OPTS='-Dgreenmail.setup.test.all -Dgreenmail.hostname=0.0.0.0 -Dgreenmail.auth.disabled -Dgreenmail.verbose' -p 3025:3025 -p 3110:3110 -p 3143:3143 -p 3465:3465 -p 3993:3993 -p 3995:3995 greenmail/standalone:1.5.8
