Perhaps amend Charles' suggestion to also provide a response when a specified regular expression is found in the message header. For example, some would find it appropriate to respond when something like the following were found: Received-SPF: pass (mybox.example.org: ... In this example, the challenge would be to have a regular expression matching only trusted mx hosts under your control and determining that the "Received-SPF:" field was written by a trusted MX host and not by anybody else (considering the content and position of the "Received-SPF:" field in the trace relative to the "Received:" fields by known trusted hosts might be sufficient for many folks). The Received-SPF header field is specified in RFC4408 Section 7. Please consider this amendment to Charles' suggestion without arguing the merits of SPF here. This is only one example of using a header field to augment Charles' original suggestion. jam
