Hello! I tried to solve this problems, spending time in google and other forums, finding information... I think I did many things...but! ..well i followed the "Perfect Ubuntu 9.04 server and ISPConfig 2" and "ispconfig_dns_godaddy". But i only host my master dns ns1.itwq.net. I have a registrar running my secondary dns and it's working ok And everything seems to be working except i receiving this 4 message/notification when i do some DNS health check on my domain. Message-1: FAILED Mail server host name in greeting FAILED. Not all of your mailservers have their host name in the greeting: mail.itwservice.no <> server1.itwq.net Message-2: FAILED XFR ns1.itwq.net allows full zone transfers (AXFR). See RFC 1034 and IETF AXFR Draft. Message-3: FAILED INFO: GLUE was not sent when I asked your nameservers for your NS records.This is ok but you should know that in this case an extra A record lookup is required in order to get the IPs of your NS records. The nameservers without glue are: xx.xxx.xx.xxx You can fix this for example by adding A records to your nameservers for the zones listed above. Message-4: FAILED Acceptance of domain literals Not all of your mailservers accept mail to postmaster@[ip_address] (Literal format). RFC1123 5.2.17 require all mailservers to accept mail to this kind of address. This is a common problem and actually can be ignored. What I need to configured? Any Help would be gratifying Big thnks.
