I see a lot of marketing emails and spam with these headers. So there is a need to make sure this is really a MLM. It is not overly complicated, considering I’m mostly the only one to subscribe to MLM with my corporate email address, but I wanted to mention the presence of such headers is not foolproof. With List-Id becoming a more generic feedback channel, I suspect that its value for indicating the participation of a MLM will further degrade.
Our operators have signing rules that can use List-ID to determine when to sign and with various signing options. For example;
[list-id:*] Enable=1 AddBodyLength=0 StripHeaders=DKIM-Signature Are you suggesting they might want to strip the List-ID for some signings? StripHeaders=DKIM-Signature:List-ID -- HLS _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
