Roger, are you working for the permanently paranoid?  Is the only 
communication to be allow safe communications?

My strong advice to you and all your customers is to run as far away as 
you can from communications of all kinds that are not strictly and 
utterly controlled with severe, instant, and precise punishment for 
anyone who dares send you something even slightly dangerous.

Thanks,
