I have installed my first Exchange 2010 server and I am getting much more spam than I had before with 2003. I do not have an additional server to install the edge server so I am stuck with the one I have. In my reading it says I can configure the Hub Transport server to filter spam, but nothing tells me how to do it. Everything points to the edge server for this purpose. Can I do this without an edge server and how can I do this?
