SPF is concerned with the details of an SMTP session (primarily,
the sender IP address, and the HELO command). SMTP is not normally
used to deliver mail between domains on the same MTA. In the absence
of an SMTP sesion, there will be no SMTP session details to check.

On the contrary, Postfix logs profusely what is happening, but
none of that involves SMTP.

How is that supposed to work, absent SMTP session details?
