I've worked in environments with MS Exchange as an internal mail
server, using qmail and others as relays, for extra security. The MS
server required specialized expertise and compatible clients, MAPI
being strongly preferred by Exchange. This has been a PITA for users
with free software operating systems. As a last resort, there is an
IMAP connector in MS Exchange, but this software functions poorly as
an IMAP server.

I would suggest a free-software mail server, with support for MAPI,
Active Sync and the likes, it there really is a need for it (consider
IMAP with idle support and open alternatives for synchronization of
PIM data). Look for the likes of Open-Xchange, SoGo, Zarafa, Zimbra
for full Exchange compatibility.

HTH,
