I asked for a copy of the (headers of the) resulting message that
Postfix delivers.
- Does it have a Received-SPF header?
- Does it have two?
BTW, The Postfix SMFIR_CHGHEADER implementation will delete a header
when the caller specifies an empty header value. That must be for some
compatibility reason.
