If you are using squid then it is quit easy to setup deny filter. Or you can use iptables.

First find out ip address of site such as hotmail.com

Code:

nslookup hotmail.com
Server:         203.145.xxx.xx
Address:        203.145.xxx.xx#53

Non-authoritative answer:
Name:   hotmail.com
Address: 64.4.33.7
Name:   hotmail.com
Address: 64.4.32.7

and use iptables to append rule to exisitng tables (better in script)

Code:

iptables -A OUTPUT -d 64.4.32.7 -j DROP
