On a low volume mail server, the only messages I see with that header are also dkim signed by mail*.mcsignup.com. MailChimp are using h=From:Reply-To:To:Date:Message-ID:Sender:Subject:MIME-Version: Content- Type; So their signature does not include the Form-Sub: header, contrary to the recommendation in that draft. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAl3cksAACgkQL6j7milTFsG9zQCdE6YkaHRj+a4I+79b/quTXZrc CsoAn1kB22Ss/Q34UIsR4zg7SIlheRC8 =LF9o -----END PGP SIGNATURE----- _______________________________________________ mailop mailing list [email protected] https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
