But the [email protected] header only appears because it is a CC. This
may not be consistent and itβs certainly not obvious or convenient
to filter on.
No. The list software has to replace the original sender's address in
the From: header with the list address because DKIM/SPF/DMARC. It then
places the original sender's address not in the Reply-To: header but
in the Cc: header because it has to go somewhere to stay preserved,
I guess. So the news@ address (not header) doesn't appear in Cc: by
accident, it appears there because it's the original email's sender.
