 the first part of what you say is true, i am emailing
 from a host on a local network behind NAT stuff.
 but i am not sending out email with an invalid return
 address.  if i was, how would i be getting this email?
 all my local DNS works fine, and if it received a query
 for local machines behind the NAT server, it would
 respond correctly, but ISP's don't pass those queries
 down to their static IP customers typically.
