Well, unfortunetly, my experience tells me it's over for you. How do you 
defend a bad decision when Management is willing to ignore both cost and 
security? I have worked a lot with exchange and found that it should 
NEVER directly receive from the Internet (send either for that matter). 
It's something the company will pay for, over and over and over again. 
However it's doubtful if they will ever see (because they don't want to) 
the real cost of that decision.
