It might be worth considering making the firewall send _ALL_ it's mail
through your mail server. That way, you cure your problem and also get the
bonus of having one central location for mail to be delivered through.
Alternatively, you could set an entry up in your hosts file for
mail.domain.com so that your firewall thinks it's at the 192.x.x.x address.
