[Gllug] MS Exchange - groupware replacement

[Alain Williams]

I have not had a look at this area recently, I was wondering what the collected
wisdom was on providing equvalent functionality. A customer is asking me,
they are essentially green field: ie no MS exchange [they have mdaemon that would be replaced],
but they use MS Outlook on the desktop. Most desktops are MS XP pro.

Wanted functionality

1) Email
2) Groupware (mainly callendaring)
3) Integration with mobiles (eg blackberry)

(1) In the first instance I would be inclined to install: exim & dovecot; with squirrelmail
for those who want webmail (eg from home). I would prob put user registration in an OpenLDAP
database for when we get them to move data files from multiple C: drives onto Samba
$HOMEs (a gleam in the eye of their IT man). This is all reasonably easy.

I might try to pursuade them to move to Thunderbird rather than Outlook.

(2) I have done before using web apps (eg Horde); if they keep outlook then I need something
    that speaks the dreaded MAPI protocol. All the plugins seem proprietary.

(3) I know little about.

So: what is best server side to do this ?
