If I had time I would be all over this - but IMHO the main problem is that
Dovecot != Exchange.? Even in small environments - unless I'm out of date,
there's no calendar, tasks or contact lists within Dovecot.
Your next best best is to use something like Horde that would allow you to
auth via ActiveSync (on Outlook 2013 clients) and manage everything else
that the users will want, with Dovecot as the mail backend.
Though I believe there could be licensing issues if you're looking to do it
for free.? I think, by license, you still need CALs for each ActiveSync
client (if you're in the US).
Auth-Wise it'd be a whole different animal.? I'm not sure if there's
anything pre-packaged NTLM + Horde - though Apache/PHP/Linux with Samba
would accept the username via GSSAPI and I suppose you could pass that to
HordeAuth.
I hate Exchange - I have a nagging 45 second delay on OWA logins ever since
I had to setup multiple NICs to get Outlook to stop complaining about
certs, and today while trying to fix that issue, AD decided to stop
replicating one of my trusted domains (and began rejecting auths for linked
mailboxes from that domain) and in short I really just hate that
environment with every fiber of my being and would love to see a decent
free Exchange replacement on *nix.
