>Yes, I use IIS 3.0 and Proxy 2.0 Installed and the Winsock proxy alreeady run and also the winsock protocol permission is already setted to Everyone.. but I do not want to install Proxyclient.. (Where can I find Proxyclient installation files?) .. Thanks

If you like it or not, you have to install the Proxyclient on the workstations to get E-Mail thrue your Proxy server. There is a subdirectory called 'clients' in your Proxy server directory 'msp'. Share this directory with your workstations and run 'setup.exe' on each workstation. After restart you can check the connection to your mail server by opening a telnet session on the workstation to port 110 of this server e.g. telnet pop3.mymailserver 110. The server should respond with: ....blablabla...server ready. Set your terminal settings to 'local echo' and type: quit. The server will disconnect. If this is ok, you can setup your outlook or outlook express. You can also setup the web installation of the Proxyclient which is also in the subdirectory 'clients'. In this case a little bit of reading in the documents or MSKB wouldn't hurt. Hope this helps.
