I have a WAN, LAN, and DMZ on my m0n0wall. I want to block all SMTP
traffic from the LAN going to the internet, and disable all SMTP traffic
from the DMZ going to the internet except for one host on the DMZ (the
mail server).

Basically, I don't want any machine sending SMTP packets out to the
internet except for one. What rules do I need to add?
