this example demonstrates the nature of CNAME, which is non-type-specific. the smtp client will try lists.dns-oarc.net/mx and get a CNAME but zero answers, so it will try /aaaa and get a CNAME with zero answers, so it will try a /a and get CNAME with an answer. thus RFC 974 (MX) is independent of RFC 1035 (CNAME). _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
