Not really, as you don't give any examples of the problem email their headers, nor any other information about what exactly is happening it's therefore difficult to answer an 'it doesn't work' type of question. You can also make modifications to the Tag/Kill percentages for the spam or add RBL lists or modify some of the other features of the product to reject unknown address (for instance), have you done that or any other tweaks that are spread throughout the forums?
You could also search the wiki for some further information or try the suggestions here:
