Hi I need help with my server, can someone please tell me whats wrong, the report is here: http://dnsreport.com/tools/dnsreport.ch?domain=zibbe.com Thank you for your help
Your mail server have no reverse dns, this is required by most of the mail servers. You can add this by contacting your data center/server provider. Your name server all recursive DNS lookup, this is newly added feature at dnsreport, most dns server are setup this way. You need to edit /etc/named.conf to fix this. This is not very critical.
