Well i just created a new mailscanner machine, configured postfix to
accept mail from our subnets only, killed the MX so it doesnt recieved
inbound mail, block the port on the firewall or in bound 25.

We already had mailscanner doing in bound for half of our domains, we
changed the rest of the MX to point to it and now have an seperate
inbound and outbound systems. Which the boss wants to double so we have
network and hardware redunancy.

Now to convince the boss to buy Julian something expensive.
