But In this case, envelope sender domain is different from domain in
header From: and then SPF checks don't apply to DMARC.
So, if you want to have proper DKIM, you must set From: to your domain
and DKIM-sign it.
To be finicky: DKIM does not care what domain is used in its d=
parameter. The alignment with the From: domain is a DMARC requirement,
not DKIM.
