Return-Path: should be set by the delivering MTA on final delivery - it 
should not appear in a message in transit.  Its basically a place to 
put the envelope-from address into although it may be munged in some 
way (ie source route back - can you remember UUCP).

That mail client is broken.  Get it fixed or stop using it.  Do not 
break other software to match its broken view of the world.  The only 
way to "fix" this is to make the list address the envelope-from address 
- that means all the bounces go to the list as well.  Do you *really 
want this???

Whole hearted agree there - and if we find what mail client it is, and 
it puts a signature line in the headers, we should probably prevent it 
sending to, subscribing or confirming a subscription to the list - it 
will make life so much better all round.
