Various Problem! Help!

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.

 

What are the outputs of

Code:

hostname

and

Code:

hostname -f

, and what's in /etc/postfix/main.cf?

 

Here is the outputs;

Code:

hostname = server1.itwq.net

Code:

hostname -f = server1.itwq.net

Code:

in /etc/postfix/main.cf

 

What's in /etc/mailname?

 

This is all in that file:

 

none answer

 

I don`t know how to do this in ispconfig panel
Can you or somebody please tell me how to?

 

You can check this with

Code:

dig server1.itwq.net

and

Code:

dig mx itwservice.no

 

this problem is now fixed, but what about with those other problems?

 

Can you check your zone on http://www.intodns.com/ ?
