[brluglist] converting from M$ Exchange to UNIX mail server

Thanks for all the helpful feedback.
Concerning a global address book: isn't LDAP used for
The company I work for is still pretty small (~15
employees, all fairly technical), but we are starting
a growth phase so now is the time to drop the M$ Tax.
I can see that the functions we currently use multiple
servers for can be combined into fewer or even one
server. I know one of the features of Outlook/Exchange
that employees use a lot is the address aliases for
fellow employees, but that could be set up easily on
each mail client. I imagine most employees will
continue to use Outlook, though some use Netscape
Navigator and even AOL(!).
The thing that surprises me after thinking about it is
that M$ Exchange does not do anything that can't be
replaced. I mean, it seems to me that once Lotus Notes
was crushed in the marketplace, M$ focused it's
attention elsewhere. M$'s attitude at first with
Exchange was that it would be a kickass groupware
platform, but it ain't. As others have pointed out,
there are many features of Exchange and Outlook that
Most of the employees do not use shared calendaring.
We do use Exchange public folders a bit, but it can be
replaced with other tools. What's the status of iCal?
Are there any free iCal servers out there?
Documenting the process would be the smart thing to
do, though I can't promise anything. I'm already a
year late on documenting another project. :)
