If you are using Linux then the built-in firewalling code called netfilter
(iptables) can handle time-specific rules for different protocols such as
http, smtp and pop3. See http://www.netfilter.org for more infomation, and
http://iptables-tutorial.frozentux.net/iptables-tutorial.html for one of the
best tutorials in existence.
