Recently I've set up an exim4 based mailing system  in a similar 
environment. My basic components are:

* virtualized ubuntu 10.04
* exim4 as smtp
* dovecot (1.x) for imap (Pop3 is also supported however we do not use 
it.)
* ldap (eDirectory from Novell) for authorization
* mailgate (Avira)as virus scanner (We also have Windows based systems 
using Outlook as mail client.)

The ubuntu system works as dedicated server and the mail users do not 
have access; therefore I've set up the virtual user's (virtual hosting) 
approach. This means that the mail server povides a directory containing 
all the accounts. Exim4 & Dovecot are configured to use them.
To reduce the administrative activities exim4 delegates most of the 
activities like delivery of mail, authorization etc. to dovecot.

Exim4 & dovecot are well documented
