Even that is unlikely since, if the same mail server is used for IPv4 and IPv6 transport, the MX would not change ... one would merely need to add an AAAA RR for the same host to the presumably-existing A RR. A hosting provider who would not let one do that is, almost by definition, not providing IPv6 support, which is not an SMPT problem. john _______________________________________________ IETF mailing list IETF@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
