write a test for this?

listToArray

	/**
	 * private method to convert a string to an array
	 * 
	 * @return boolean
	 */
	private String [] mailToToArray(){
		List<String> mailToList = new ArrayList<String>();
		try(Scanner emailScanner = new Scanner(mailTo) ){
			emailScanner.useDelimiter(":");
			while ( emailScanner.hasNext() ){
				mailToList.add(emailScanner.next());
			}
		}

		return mailToList.toArray(new String[mailToList.size()]);
