If it happens to survive (such as to recpients of the original message who are not on a mailing list, so they get a direct copy) then their DKIM evaluation engine ought to pay attention to the 'strength' of the different signatures. Also note that the weaker signature is enabled by the DKIM-Delegate field, which specifies what intermediaries are tolerated. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
