This will *still* break anything using DMARC, because neither DKIM nor

Ideally the email modifications are disabled entirely. The emails can

reliably detected using the List-Id header and filtered based on it.

Hi Tim
The suggested method is not modifying the emails as you suggested,
unsubscribe links should be handled by adding a List-Unsubscribe header
(which almost all major providers use to show inline unsubscribe links)
though that needs a one click link which the current link is not (so
again a little more work)
Im not sure how big of a change that will be (as it will be many people
updating filters I assume) but yeah that's a much better way. I assume
people must get dmarc reports now as the SPF and DKIM checks will both
fail currently ?
Thanks
Scott
