[Zope] NotMail

I just attempted to install NotMail. Not much luck. The import appears to not be happy. I get the following Traceback. NotMail Import Traceback Traceback (innermost last): File "C:\Program Files\Gameshop\lib\python\OFS\Application.py", line 393, in import_products product=__import__(pname, global_dict, global_dict, silly) File "C:\Program Files\Gameshop\lib\python\Products\NotMail\__init__.py", line 89, in ? import NotMail SyntaxError: non-default argument follows default argument (line 199)
