Mohammed Baik,

thank you for grabbing my atention to ping external hosts and to telnet the
mail server by its IP, i never thought about that before, i don know why !!

thank you so much, i've created 2 server puplishing rules for our Internal
DNS servers, one for query and one for zone transfer

and everything is working now, thank you again :)
