I believe Holger Mauermann's patch fixes most of these issues, from NEWS:

* Holger Mauermann's bounce patch, to use a NULL envelope from, not

  added Subject header, rewording the human readable part. (Matthias Andree)

We'd need to check if the SVN version still forwards the message to the
postmaster.

Perhaps time to roll 6.3.0-beta1 so that people can check if their
