DKIM signature tests appear to be more common than ARC support on the receiving end of things. If Mailman 3 is rewriting the message headers correctly, which I don't doubt, I see no reason not to add both ARC and DKIM signatures, especially when the ML continues to prepend "[mailop]" to message subject lines and thereby invalidates existing DKIM signatures. -Ralph _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
