I need your help again hehe.
I told my ISP, and he told me which domain he delegated to us. However, I explain a bit how to make the unit now:
I have an ip block for a physical interface, everything is managed by Fortinet. ok, in ZoneEdit I created the reverse DNS with only one ip (that ip is where I posted my mail server, and in the reverse dns I declare that public ip.
For example I have this ip segment
this first ip is my provider 192.168.0.1
- 192.168.0.2
-192.168.0.3
-192.168.0.4
-192.168.0.5
* I used an ip for the mail server
then create a reverse dns in the edit zone like this:
192.168.0.5/32 but when I go to dns configuration - reverse DNS I try to get information ... but I don't see anything after this text:
"They will also need to configure the following CNAME records to map each IP in the network block to the ARPA proxy address in our system:"
anyway I created a ptr record with the public IP and added the host: xxxxxx.something.com
I do not know if you understand. The thing is, I keep getting spam emails.
Thanks and sorry for the inconvenience
