[Leaplist] exchange replacement?

[jms1 at jms1.net]

howdy all-

i have a potential client who needs an exchange server, but can't afford
100 client access licenses and doesn't want to "hack" anything to run
illegal or unlicensed software. they aren't married to windows, and as
long as the clients on their (desktop? browser?) do what they need, they
don't care if the server is windows, linux, mac, solaris, or an old
refrigerator.

specifically, they need:

- email (obviously, and that's not a problem)
- shared calendars
- shared task lists

the only other thing i remember exchange server offering is shared storage
folders, and (1) they don't need that, and (2) if they did, i'm pretty
sure dovecot (the IMAP server i plan to use) already has a way to do it.

i *know* i'm not the first person to run into this issue, and i plan to do
some research on "groupware" stuff later this evening. i'm just curious if
anybody else on the list has had any real experience with this issue, and
what they ended up doing.
