Squid seems to be your friend for www/ftp.

What do you mean by accessing mail without authenticatoin? hotmail or 
similar? If you want to provide mail service yourself, then users must 
authenticate in order not to be able to read others mail, also by 
authenticating smtp and only allow smtp to your server you prevent virus 
and spambots from spreading.

Cheers, Erik
