Almost.  The delivery MTA in question has to recognise that 

  list-bounces+claw=kanga.nu at kanga.nu

is really the same as:

  list-bounces at kanga.nu

and hand off appropriately.  To do this the target MTA requires plus
addressing support.  Heck, that generic ability to distinguish and do
that mapping is the definition of "plus addressing support in an MTA".
