#444 authenticate against Windows Xchange server

[Anonymous]

I have been using MRBS for years and my setup has been setup to authenticate against a Linux server running mail accounts (imap and pop3). The pop3 authentication has been working good.

My organizations is now turning to a Windows setup and I want to authenticate MRBS users agains the Xchange mail server, if possible. The Xchange server seams to be available outside our network as I can setup my iPad and Android phone to receive and send mails from the server.

I don't think AD is available (not 100% sure). Any idea how a configuration file in MRBS has to look like to authenticate users against a Xchange server? Thanks!
