which web mail / calendar to use

[Michael Grant]

I'm looking for a web mail and calendar to install on my freebsd box.
Ideally something "web 2.0" like gmail and google calendar is what my
users are after.

In some searching around, I turned up Hula (http://hula-project.org)
and Zimbra (http://www.zimbra.com).  Both have open-source versions.
Zimbra seems more mature.  Neither seems to be easy to install on an
existing freebsd box and both seem to replace everything including the
mailer and popd/imapd.  It's not clear to me if anyone has ever
succeeded in getting Hula working on Freebsd.

Has anyone had any luck with any other packages?
