Email Auto Config
 

I have a need to know how to setup my email server so that it will auto configure the email clients. I am not sure what to even call this process.
Outlook will try to log into a server and set it up and so will many cell phones. I set up my server using the Perfect Ubuntu 8.10 server and have isp config installed and running. just need to know where to go from here.

I'm not sure if this is possible. That's the first time I hear of such a thing...
