the root-servers.net are not involved. the root-servers.net refer a query= =20 for afalfdja=E6lfjadsj.com to gtld-servers.net that verisign runs. There is no MX for alfja=E6lfjalfjalfjfd.com, only an A record so SAV would= =20 run against 64.94.110.11: # telnet 64.94.110.11 25 Trying 64.94.110.11... Connected to 64.94.110.11.
