No?
I don't have specific data, but since ADSP is so controversial and no third-party authorization mechanism has been endorsed so far, my guess would be that there are only two possibilities: ESPs are signing using their own domains to sign, or ESPs have customer key space delegated to them one way or another. I don't have hard data about which is more prevalent, but we're definitely seeing both in the stats reports I'm getting now. _______________________________________________ dkim-ops mailing list [email protected] http://mipassoc.org/mailman/listinfo/dkim-ops
