For your anti-spam solution, you might check and see what Brightmail can offer. They work primarily with ISPs and ASPs, but they may have a solution that will work for you. I used to work there, and they are decent folks.

After man phone calls it seems that Symantec has ruined this product. I couldn't find anyone that would talk to me about anything other than software I would put on a windows server.

I think Brightmail is now an ISP-only product that their normal salesforce doesn't know about.
