1. Why are the non-delivery notifications sent to
<postmas...@wikimedia.org> rather than to <w...@wikimedia.org>?
NDR have to be send to Return-Path of original message, thus it depends
what was in its MAIL FROM. IMO including foreign (google) IP range opens
big hole in SPF.
The bounced message had:
Return-Path: <w...@wikimedia.org>
To: <ambe...@sbcglobal.net>
Neither of those seem to have anything to do with the Received: from
shopify.com line and with the diagnostic (which mentions
ebuerg...@sbcglobal.net). I doubt the From:
_𝐀𝐟𝐟𝐨𝐫𝐝𝐚𝐛𝐥𝐞_𝐖𝐢𝐧𝐝𝐨𝐰𝐬_ (in MATHEMATICAL BOLD) is real,
and the Subject: doesn't seem to match the content of the message.
Did ARC seals verify?
Best
