Seems to have find my problem. It has not to be done with the mode "server only".
After running
command:
dig 2.0.0.127.zen.spamhaus.org
from tutorial
https://www.spamhaus.org/faq/section/DNSBL%20Usage#108 How do I check my DNS server results?Having setup DNS with main DNS server from OVH (for Dedicated Server) : 213.186.33.99 -
this command was getting no result,
after adding a secondary DNS in "Manage Domain" from DNS Server I was able to get a result.
So my Provider DNS was problematic.
In my /var/log/sqpsmtpd/current logs: dnsbl: pass
