I have a user sending commands to listserv.  His mail contains both RFC822
FROM and a SENDER headers.  Listserv APPEARS to be using info from SENDER
header instead of the FROM header ( in this case, the SENDER contains
a bad nodename while the FROM header is correct )
 
Is this really what is happening and what SHOULD happen ( red herring ? )
If so, is there any way to make the FROM data used ?
