Your cnops.org.ma.hosts file isn't set-up correctly, you need to have it look like this:
Code:
$ttl 38400
@ IN SOA hostname.mydomain.com. root.hostname.mydomain.com. (
2005110200
10800
3600
604800
38400 )
@ IN NS hostname.mydomain.com.
@ IN MX 10 hostname.mydomain.com.
@ IN A 192.168.1.3
hostname IN A 192.168.1.3
mail1 IN CNAME hostname
mail2 IN CNAME hostname
Where it says 'hostname' that should be only mailsrv for your system not the FQDN.
I don't think posting your details is any great risk as you're on a public IP and not very hard to find but if it bothers you then just edit out the details.
