PTR/RDNS Records for Mail Server

[andars]

How would I implement a ptr/rdns record for my mail server under ispcp if I were to get my ISP to delegate control of reverse dns records to me. I've read around, and I'm somewhat confused as I'm not entirely familiar with BIND.

Well, you need a zonefile like this:

example: ip is 12.34.56.78

myipblock.zone:
$TTL 1D
@ IN SOA [soa record]
IN NS [your ns - ]
IN PTR my.own.hostname.tld.

and in the named.conf it may look like this:

zone "77.56.34.12.in-addr.arpa" in {
type master;
file "myipblock.zone";
};

so, the specia thing is the ".in-addr.arpa" and the PTR

Maybe we'll bring ispcp to do that too :-) - but this has less priority...

Okay, thanks for the help. I still have to ask my ISP about delegating control to me. I have a commented entry setup now though.

Please a little help here or anyone who knows about it
I tried to implement the PTR record in my server (Debian etch 4.0 - IspcpRC4), because some emails don't reach their destiny

First I've modified the named.conf file, and it looks like
----------------------------------------------------------------
// dmn [programs.cl] cfg entry BEGIN.
zone "programs.cl" {
type master;
file "/var/cache/bind/programs.cl.db";
notify YES;
allow-query {
any;
};
};
zone "223.162.13.190.in-addr.arpa" {
type master;
file "/etc/bind/programs.zone";
};
// dmn [programs.cl] cfg entry END.
-----------------------------------------------------------------

Then I've created the zone "programs.zone"
-----------------------------------------------------------------
$TTL 12H
$ORIGIN programs.cl.
@ IN SOA ns1.gnap.cl. postmaster.programs.cl. (
; dmn [programs.cl] timestamp entry BEGIN.
2008051800 ; Serial
; dmn [programs.cl] timestamp entry END.
8H ; Refresh
15M ; Retry
4W ; Expire
3H ; Minimum TTL
)
IN NS ns1.gnap.cl.
IN PTR programs.cl <--( first I tried with ns1.gnap.cl here,but nothing happened)
--------------------------------------------------------------------

Later I restarted bind , and the log showed me
--------------------------------------------------------------------
gnap named[7214]: command channel listening on ::1#953
gnap named[7214]: zone 0.in-addr.arpa/IN: loaded serial 1
gnap named[7214]: zone 127.in-addr.arpa/IN: loaded serial 1
gnap named[7214]: /etc/bind/programs.zone:3: ignoring out-of-zone data (programs.cl) /<--( why ? )
gnap named[7214]: zone 223.162.13.190.in-addr.arpa/IN: has 0 SOA records /<--( why ? )
gnap named[7214]: zone 223.162.13.190.in-addr.arpa/IN: has no NS records /<--( why ? )
gnap named[7214]: zone 255.in-addr.arpa/IN: loaded serial 1
gnap named[7214]: zone atlanticpearl.cl/IN: loaded serial 2008081100 (<-- the other domains start here)
gnap named[7214]: zone cafemillenium.cl/IN: loaded serial 2008050800
gnap named[7214]: zone demo.cl/IN: loaded serial 2008052701
--------------------------------------------------------------------
When I check it in freedns.ws ,in PTR record, it shows me
Server: 190.13.162.223
Address: 190.13.162.223#53

*** Can't find programs.cl: No answer

and I still without PTR records

Could you help me with this ?

thanks
