I added a PTR record for my mail server on our DNS server a week ago but after various tests on the net, it still can't reverse DNS.

The reverse lookup for the mail server works fine on our DNS. Why hasn't it propagated?

did you change the serial number in your named configuration file for that domain name?

Serial number?

There is an entry for the IP range in the named.conf file if that's what you mean.

no, not the named.conf but the zone file that the named.conf is pointing to.

at the top of the zone file should be something like:

$TTL 604800
;
abd.org. IN SOA ns1.a.net. t.mail.adb.org. (
2007070403 #serial number
3500
3600
1209600
86400 )

serial number should be changed to the YYYYMMDDHH of when changes are made to the zone.

Oh ya, but I tought the serial number only had effects on slave DNS servers?

Please ask the ISP from whom you got your IP address to set a reverse record for you.
