Quick and dirty email server for development.

wiser.start()

addShutdownHook {
    if (wiser.server.isRunning()) {

        wiser.stop()

}

println "Running...\n"

while (true) {
    if (knownMessages.size() < wiser.messages.size()) {

        knownMessages = wiser.messages.collect { it }.asImmutable()
        newMessages.groupBy {message ->
            message.getMimeMessage().getSubject()
        }.each {subject, group ->
            group.first().getMimeMessage().writeTo(System.out)
            println "\n\n".padLeft(79, "-")
