This is what I tried:

https://gist.github.com/2631381

So, instead of hacking the message, I just made it look for that weird Content-Type and parse what's in the, "body" as if itself is an entity, even though it only holds the headers. Really strange. You'll see a few lines, like this:

                if ( $entity->head->mime_type eq 'message/rfc822') {
                    $orig_msg_copy = $parts[0];
                        $list = $self->list_in_list_headers($orig_msg_copy);         
                }
                elsif($entity->head->mime_type eq 'text/rfc822-headers'){ 
                    require MIME::Parser;
                    my $parser = new MIME::Parser;
                    $parser = optimize_mime_parser($parser);
                    eval {
                        $orig_msg_copy = $parser->parse_data( $entity->bodyhandle->as_string );
                    };
                    if ($@) {
                        warn "Trouble parsing text/rfc822-headers message. $@";
                    }
                    else {
                    }
                        $list = $self->list_in_list_headers($orig_msg_copy);
                }

With that, if I then parse that message (I changed the list's shortname):

justin-4:plugins justin$ ./dada_bounce_handler.pl --test test.eml --list j --verbose Test #1: test.eml

You at least have something to work on (and make a new rule, for) - although, Dada Mail isn't looking at that first part of of the bounce:

This is the mail system at host mailscan12.emaildomain.nl.

Which sort of stinks.
