Steffen,

Because Google / Gmail / Google Workspace will put out DKIM
requirements for every email from bulk senders from Feb 1st - not ARC
requirements. From what I understand, DMARC alignment only happens on
SPF and DKIM alignment, not on ARC alignment - and because of that,
DKIM is relevant for us.
