Bind Problem :(

[Sorkin, David (David)]

Mahmood,
	You can't create PTR, or any other kinds of records that are in a zone for which you are not delegated authority. If you are not authoritative for the reverse zone that contains the address of your mail server then it is someone else's responsibility to update it. You can check on http://www.arin.net/whois/index.html to see who that might be.

Dear Eric,
Thanx For your help, Excuse me because of my Bad English,
Don't we need a record like this:
ddd.ccc.bbb.aaa.in-addr.arpa.  IN  PTR     mail.foo.com.
 in a file with this name:
db.aaa.bbb.ccc
With respect to this fact that  aaa.bbb.ccc is not in our ip addresses
range.
