Thanks it seems to be an issue with spamhaus, here's the result:

[root@mail ~]# host 107.178.203.192.zen.spamhaus.org
Host 107.178.203.192.zen.spamhaus.org not found: 3(NXDOMAIN)
[root@mail ~]#
Use a proper DNS server (like somebody on this thread already suggested)

Thanks as I was telling I have one, but I think the issue is with the forwarding it's been made to a public dns server. Should I change it to a particular one? (ex spamhaus)

Note that public recursor like for example 8.8.8.8 typically exceed the limit of queries spamhaus is willing to accept per source and are therefore blocked. For RBL queries you really should not use a public forwarder.

Regards

Andreas
