Assumung that these headers are added by a spam filter, this would
require a Milter plugin that examines messages after your spam
filter, and that dynamically adds a forwarding address to the message
envelope (i.e. in addition to the existing local mailbox address).
Milters can be implemented in a variety of languages including
Perl and Python. If all they do is inspect message headers, then
the performance impact should be limited.
