Define "turn off internet access". Did you turn off the network interface at the computer or just unplug the network connection?

In my mind, "turn off network" and "get mail" are mutually exclusive. All SMTP mail access requires an IP connection. Disable the IP connection and you can never get mail from anywhere.

You could set up some address specific firewall rules. See man ipfw. But trying to allow all local traffic (including SMTP, DHCP, Bonjour, printing, etc.) while blocking IP traffic from the Internet as a whole is a non-trivial task.
