Hi,

I don't understand the meaning of line:

localhost       A       207.228.252.47

In addition, if ns0 corresponds to 207.228.252.47 ,
I think www and mail must have CNAME records instead of A record
since they correspond to the same IP address.

(and if I helped you, please just thanks, no french kiss !  ;-)) )
