Keeping the target of forwarded messages private needs to be addressed at

That seems like a great way to destroy mailing lists by not telling them
which recipients are bouncing.
Temporary failures (over quota) don't hurt mailing lists. Permanent failures
(target account takedown) deserve bounces right from the forwarding address.
Um, the mailing list *is* the forwarding address.
Oh, well, no, in that case the target address is not meant to be kept secret.
In any event, I think we agree that failure reports are not worth a lot of
effort here.
I'd look for ways to trim them down a bit. Just enough to let them be
privacy-wise credible. Besides skipping forwarded stuff (including mailing
list) and an enable-by-domain feature, avoiding external addresses in ruf=
could be another simplification. Not worth?
