[plug] Groupware for Linux

[mystery]

Hi all,

Does anyone know if groupware is available for Linux?  I understand Lotus
is porting the Domino server to Linux, but they have no plans to port the
client.  Currently Notes client runs somewhat badly under WINE.

I'm looking for a grouware solution...

Many thanks

PS I have a CD of Mandrake Linux 5.3 if anyone wants to borrow it.  It
installed over an existing copy of Redhat 5.2 without any problems - as
easy as a Windows install.  The drop-dead gorgeous KDE desktop popped up
and worked first go.
