Good luck on that. ;-)

dovecot can support any PAM authentication method, and you can use PAM 
to either do NTDomain or ActiveDirectory logins.

Check the wiki:

There isn't anything particularly good right now for 
calendaring/scheduling (though there are some projects out there in 
alpha stage).

You could check out Zimbra, which does calendaring and scheduling, as 
well as supporting lookOut (with the commercial license).  But it is a 
monolithic beast right now; you have to install a whole suite of their 
own customized RPM's, so you don't get to use dovecot.  It does store 
the messages in the database and has a wicked cool AJAX web interface, 
but I decided it wasn't worth it just yet...
