/**
 * This test tests whether or not it's possible to use the SendHtml functionality to send mail that will be <i>relayed</i>. 
 * </p>
 * The situation that this test is the following:<ol>
 * <li>You have a jBPM process that runs on a server on domain "willywonka.com".</li>
 * <li>However, you want to send e-mail, from a node within your jBPM process, to e-mail addresses at "oompaloompa.org". </li>
 * </ol>
 * </p>
 * Unfortunately, there's not really a way to test this with the Wiser/SubethaSMTP framework, which means you have to use real 
 * mail/smtp servers -- which is what this test does. 
 * </p>
 * Fill in the fromAddress, fromPassword and toAddress (and if neccessary, modify the user and smtpServerFrom fields) and run this
 * test. If no exceptions are thrown -- and you receive an e-mail, then you're good!
