Okay I see what you are referring to as 'souped-up IMAP' as the Zimbra
type solution, where there is a one-stop one-package install.  I
personally have never worked with any of those.    I thought you were
implying that a properly designed system such as I've built was
considered as 'souped-up IMAP'.  (And I see a properly designed e-mail
system as WAY more than souped-up IMAP, obviously)

When I've made the soup, it's been pretty tasty however - with real
solid anti-spam and anti-virus, clustered storage on the backend (over a
completely open protocol to boot),  we could actually move users and
even add more storage servers on the backend without any downtime for
the existing users, etc.

What I would really like to see is if there was a product, such as the
aforementioned on on your first post, that was completely capable of
speaking all the right protocols for Outlook clients, but on the backend
supported a real LDAP system, supported open-source mail processing,
routing and storage systems such as Postfix and maybe Cyrus IMAP etc.  
I still think that would be very viable.  Essentially replacing the
'Exchange' piece of the equation with something that a real admin can
really do awesome stuff with.  Eventually, those protocols should be
exposed to Thunderbird, evolution, etc. so that Outlook is only one of
many choices in the field.  It would be neat to actually market
something open and flexible - if it contained every combination of those
little features that Outlook users can't seem to change away from.
