Ahh, I see what you're doing, you're looking up the SOA. Which is
basically forcing the query down to the spammer's DNS server, and
opening yourself up for a DoS attack.
You're seriously concerned by DoS. You may probably get some relief by
unplugging your MX servers from internet. It is the red cable with the label
"Warning: potential DoS carrier!" :)
This statement boils down to "if a security risk exists, there's no
reason to avoid making it more likely"
At that point, why bother using firewalls? If your seriously concerned
about hacking attempts, unplug your network.
