It's possible to do this only for domains that advertise p=reject. They deserve what they get.
If there are any issues that seem like they can be addressed in upstream GNU Mailman (unfortunately, we don't carry a stick big enough to convince blockheaded mail domains not to publish p=reject), let me know and I'll push it with the Mailman devs. No promises, of course.
Gmail *recipients* (which includes most redhat.com subscribers these days) need this rewriting as well. Discarding mail is always a policy decision carried out by the recipient, so it needs to be configurable for mailing list subscribers. The mailing list server cannot detect this recipient behavior automatically.
No, but if the mailing list server rewrites when the sender has a reject policy then the email gmail receives will no longer violate the policy so they won't put it in the spam folder.
Based on some reports, I don't think this is how the Gmail implementation works. It will discard mailing list mail for senders with a DMARC policy that does not set p=reject, too.
Thanks, Florian
