Stopping the receiving is easy -- just create an empty file in
/var/mail/$username and change it's permissions to 444.

Dunno how to stop someone from sending mail.  Maybe an iptables rule
that uses the --m owner --uid-owner switches to block port 25 to
that user?  Course, if you're running potato, you've probably got a
2.2 kernel, so this isn't an option.
