To once again clarify how erroneous bounces will be filtered:
Any email system that allows a user to generate a white list will be
able to readily
generate a 'bounce white list' composed of all addresses that the user
had sent
mail to within the past few hours. The bounces generated by my system
will
be identified as bounces by a universally recognized tag. The user
will
only see the bounces that are contained on the bounce white list.
Will that work in a world that still has a lot of mailing lists that
don't rewrite the envelope sender data, such that bounces go back to
the sender but from addresses the sender didn't send to? Or do you
break all such systems and require their replacement with something
different, like SPF?
Personal email forwarding addresses are in some respects a special case
of the above, except you can probably make a stronger argument for
wanting envelope senders that do relate to the original sender, and not
to the agent in the middle, for example for use by vacation programs at
the final receiving site.
