Groupshield isnt compatible with a number of anti-spam add-ons such as GFIs offering (confirmed by their tech support). MailMarshal also isn't confirmed as working with it although they don't actually exclude it. But as MM has integrated virus scanning (made by McAfee) its not a huge problem there. I recently had to abandon Groupshield as I couldn't find an anti-spam product that explicitly says it works with the product.
