It attempts to parse bounce message to determine the address that is
bouncing.  For obvious reasons, this doesn't always work.

ie VERP.

Mailman does not currently support VERP.  Adding VERP support for
version 3 with various levels of impact (all messages VERPed, some
messages VERPed, only the password reminders VERPed, etc) has been
discussed and seems likely.  


  Potentially you could embed a VERP layer at the MTA outside
  of Mailman and then munge appropriately, but this is not quite a
  trivial effort.  (Rewrite the envelope to pass thru a custom
  handler, then have that handler re-write bounces to a Mailman
  conformant format with the appropriate subscriber address in the
  "right place").
