There is also Exchange4Linux (http://www.exchange4linux.org/ and 
http://exchange4linux.sf.net/) -- I've been playing with this off and on 
for a while now.  It looks _very_ promising.  Everything is stored in a 
Postgres database, it used CORBA to talk to the proprietary Outlook plugin 
and the e4l-side of the protocols are all documented and open.  

- everything is stored in postgres (emails, attachments, you name it)
- CORBA is not NAT-friendly
- the IMAP server is written in Python

It's still in development but as I said, it's actually working rather well.  
They even provide a 32MB chroot environment for testing it out, although 
it's a couple versions behind (and VERY slow because of that).
