I installed today sucessfully SCALIX on Debian Etch box.
If someone explain to me how to write "how to" I'll write it.
( It sounds funny, isn't it? I need How-to for writing How-to
)
BTW I also managed to install HylaFAX altogether with most important functions (like email to fax gateway, and vice versa) on ISPConfig Debian Sarge Box.
