Configuring Proxy for POP3 and SMTP

asumming you don't have any filters blocking pop3 and smtp. If your telling me that web access is ok, installing the proxy client located at \\proxyserver\mspclnt\setup.exe will allow then access to all protocols on the internet including pop3 and smtp. Again if you want to block other protocols setup filters.

In Outlook click ?Tools/options? then the ?Connection? Tab, then under ?Internet Connection Settings?, click ?Change?, and finally ?Lan Settings?. Here you want to check the box for Proxy server and enter it?s IP address and what port your proxy server has been set up to use.

POP3 and SMTP passing through a Proxy Service do not use the web proxy services. Out of the three services that run, Web Proxy, Winsock Proxy and Socks Proxy, the only one that is used for this is Winsock Proxy.

There is a shared folder on theproxy server that is called MSPCLNT or something like tha t. There is a setup file in there....run that on the client machines and make sure that on the proxy server, you do not have permission set for the various protocols...check out the properties of the winsock proxy service in the MMC...

Hope this helps.

As mentioned previously the functionality you are looking for is part of the Winsock Proxy. Occasionally I've seen this problem with small peer to peer networks where the Proxy server is just a member server. In an actual domain network, the usersmust log on at the clients and get authenticated by the Domain controller. In peer to peer sometimes the importance of logging in with a proper account and password is forgotten. You must log into a client system with a user account that has been given access privileges to the Winsock proxy for this to work. Logging in to the client with a different user name and password than is required by the ISP for the POP3 mail access, sometimes changes the pop3 login settings. So in summary make sure users have user IDs and passwords on the Proxy server. Make sure those users have access privileges to the Winsock Proxy. (At this point you should be able to tell that you?re getting out to the Internet.) If you are unable to login to your POP3 account check username and password settings for that account.

I had this problem with 2000pro boxes, had to login to workstation as admin, remove proxy client(uninstall) del all remaining client files (c:\mspclnt) and a few entries in registry(dont del the clock!!:-)!)then reload client as admin, login in as user, run install from start/programs again,and all is well. Does this make sense? no, but it works.
