With all the spoofed mail these days from viruses like klez, I'm thinking of adding this header to all of our lists.  Then I have a chance of seeing whose machine is infected when spoofed mail is sent to a list.  Any thoughts?  I normally have notebooks turned on for all lists and erase them after two months.
