I haven't had time to sit and poke at the offending mail server to see
if they react to the reply to: or the from: header.  I'll have to mess
with that this weekend when traffic is lower on lour lists.

I can't believe they are doing this either but unless someone invents a
machine capable of perpetual motion in the next couple of years, I'll
probably still have a job. ;)

This would probably work for us.  I was throwing this out to the list to
see what other approaches existed than the ideas I had.  It didn't occur
to me to just obscure the domain name.  I'd be happy to help out with
either the coding or testing if you need the help.

Thanks for the great suggestions all.
