The thing is when you do DSfirewall sendmail doesn't actually try to
send the mail direct to firewall.domain.com.au it actually does an MX lookup
on firewall.domain.com.au and then if the MX doesn't exist it will send directly
to firewall. To prevent this try DS[firewall] or to avoid DNS problems all together
