    By default, inbucket listens on the following TCP ports:
      0.0.0.0:2500 - SMTP
      0.0.0.0:1100 - POP3
      0.0.0.0:9000 - HTTP

    You may change these ports by editing #{etc}/inbucket.conf

    Once inbucket has started, access its web interface at:
      http://localhost:9000/
    EOS
  end

    system "#{bin}/inbucket", "-help"
