Yes folks its "Can of Worms" time again....  Seriously though the
re-write
in the config file I emailed work except for the envelope problem...

Oops!  I'm a moron (albeit an incredibly talently and hansom one).  My
brain
was left inadventenly in "SMAIL" mode and I'd just added the variable
name as a toggle.  I've now added the '= false' and its happy.

So the rewrite rules work as much as I think think they can.  All
headers and the envelope From are re-writen.  The envelope To: is left
alone.  It is re-writing this that was causing the local machine to
think mail should be delivered on it.

I can't think of any way leaving the envelope To alone would cause a
problem.  Except, of course, if the target machine hasn't added
envelope_to_add = false !
