	 * 
	 * This constructor creates an email message that can be sent using the
	 * provided session.
	 * 
	 * 
	 * 
	 * The session defines the configurations for relaying messages, and is
	 * specific an organization's network. In the simplest case, the session
	 * requires an SMTP_SERVER and SMTP_PORT to relay
	 * messages. For example:
	 * 
	 * 
	 * Properties sessionProps = new Properties();

	 * sessionProps.put("mail.smtp.host", SMTP_SERVER);

	 * sessionProps.put("mail.smtp.port", Integer.toString(SMTP_PORT));

	 * Session session = Session.getInstance(sessionProps);

	 * 
	 * 
	 * @param from
	 *            email address
	 * @param to
	 *            email address
	 * @param subject
	 *            as plain text
	 * @param body
	 *            as either html or plain text
	 * @param bodyIsHTML
	 *            whether the body should be sent as html
	 * @param session
	 *            the session defines, at a minimum, the server and port used to
	 *            relay email messages
