Dear list, I've successfully installed ISA 2004 on a test network (home) using the edge template and "unrestricted access". Browsing works fine but I can't get Outlook or Outlook express to connect to remote mail servers from the two XP clients, though I can connect from outlook on another server. Looking at the logs the pop3 packets are dropped as unrecognised IP traffic port 8080 when sent from the XP clients but accepted as pop3 port 110 when sent from the server! What is going on? I've tried using the firewall client but it doesn't change things. Many thanks Andy Fairley
