Look into ASSP (Anti Spam Server Proxy). This is my favorite solution for a number of reasons. XMail has a number of tools to help with SPAM, and they work well, but I found ASSP to be significantly ahead of any specific XMail integration solutions I was able to come up with or implement after about 6 years of using it, so that's my advice.
