Exchange replacement, again...

[Madison Kelly]

Hi all,

   I know this was talked about recently but for the life of me I 
couldn't find the old thread(s) anywhere... Forgive me for asking again.

   Can anyone recommend a method, how-to or general pointer to an 
application or collection of applications that would allow for providing 
similar services that Exchange does except on Linux? Obviously 
compatibility with MS Outlook would be nice however that is not a 
requirement is there is a windows client (Mozilla?) that can access 
these services. In fact, I would prefer the later option over trying to 
stay inter operable with MS.

   Essentially I need personal e-mail, private and shared contacts, 
shared scheduling and itineraries and so forth. I would like this to tie 
into Linux-based network user authentication. So far, I am thinking I 
will be using PAM for authentication, Samba (via PAM) for windows access 
and print serving (over CUPS) with an OpenLDAP database to store actual 
user data (authentication), e-mails, contact lists and so forth.

   Am I on the right track? Is there a canned or partially canned 
application already available? I am trying to stay as completely within 
the GPL as possible so I would like to avoid proprietary solutions (such 
as what Suse offers).

   Many thanks all!

Madison
