Re: Why no List-ID header in the postfix-users posts?

[lists]

How would a get a print out of email uses that fail DKIM, SPF, or both? A few months ago there was chatter about how to rewrite the subject header to indicate the SPF and DKIM status. Unfortunately nothing further. Further, how does DKIM prove the message wasn't altered? To my knowledge, SPF proves the message came from a qualified server and DKIM proves the FQDN is a match.

I get regularly authentication failures (forensic reports) when posting to this list. Propably because my domain is set to require mandatory DKIM signing and postfix list server isn't. However, I don't think there should be any subject tags.
