Install Zarafa on a Ubuntu vserver with IMAP and ActiveSync + a webserver

After fiddling with Conifxx (which is included in my hosting package) and ebox and other packages I ran out of time to set up my server myself.

What I have is a vserver running Ubuntu 8.04 LTS.

What I need:
- a webserver (with an easy way to host multiple domains)
- ftp access to it obviously

- an IMAP mailserver
- running Zarafa with ActiveSync (z-push)

This simple setup task should be doable in two hours paid time for someone with experience in that area.
