How to configure autoconfig server for Mac mail

Hi There,

We are running a mail server which host few domains, Now my question is how Mac mail will try to find the Mail server settings ( port , Imap or Pop and all settings )

Like thunderbird use http://autoconfig.domainname.xx/ , So how can i setup some thing So mac mail will find all the settings byself, user do not need to do any manual setting.

Thanks,

Anant
