SpamSieve not checking all emails

I have installed SpamSieve for Entourage 2008 but I have noticed that it only checks about 1/3rd of the emails that I am receiving (as per the SpamSieve logs.) Most of the email I received do not show up in the log and do not get checked. I am using Mac OSX 10.7.5

Why is that?

It sounds like there’s a setup problem, either in Entourage’s rules or mailing list manager. Please see this page.

Thanks. I had already goner through all that though. The good news is that I followed the recommendations in this post and removed the rules in my Mailing List Manager and that seems to have done the trick.
