Bounce messages

Hello list,

I took over maintenance of a RT 4.4.0 installation and we are having
issues with a plugin
(https://github.com/MarkHofstetter/RT-Extension-BounceEmail) that is
supposed to bounce messages.

Issues:

  1. the bounced email has the mail address of the RT installation as
    sender instead of the ticket requestor.

  2. it works with plain text mails but not with text/html mails.

any help is appreciated

regards
david
