One message, two providers, one DKIM signatur= e.

Postmark and Resend each get their own copy of these exact bytes.= If the two
stored versions differ, the difference is the provider, not = the sender.

Line endings matter here. So does a non-ASCII character:= caf=C3=A9, =CE=A9, =E6=9D=B1=E4=BA=AC.
