In Exchange 2003 there was a connection control box in the SMTP virtual server properties that I could configure to only accept e-mail from a list of IP addresses. I had it configured to accept e-mail from my local LAN, and the external IP of my anti-spam service provider. I now have SBS2008 and Exchange 2007. I cannot find a connection control box or similar to restrict e-mail reception to just my LAN and anti-spam server provider. Am I not finding it or is it done differently in Exchange 2007? I would appreciate instructions on setup if it is different. I don't have an edge server, just the SBS box.
