mail, file, web, print, vpn on ubuntu server 11.04

[pvthodson]

I would like to get the following service up and running on ubuntu server 11.04 (mail, file, web, print, vpn). The situation is going to be 1-5 users preferably one server machine but can run multiple servers in vmware esxi if necessary. The current network has a cisco small buisness wireless router (10, 100, 1000) and a small buisness switch (8 port). File server needs to be able to communicate with windows, linux, mac, and xbox 360 (if another service is nessacary for the xbox thats fine). Mail needs to have some sort of spam filter. VPN will on support one user for now. Im sure that SSH and FTP might also be a good idea and will probably accompany one of the other services anyway. I guess to sum it all up I would just like a detailed guide on where to start and what to install and how to configure it? Or even possibly a distro that has these services by default?

Thanks in advance.
