<Some...@CliffordChance.com>: Host or domain name not found. Name
service error for name=mail.global.frontbridge.com type=A: Host found but
no data record of requested type
From the server itself:
[root]# host mail.global.frontbridge.com
mail.global.frontbridge.com has address 65.55.251.22
What could be the problem?
You're using different DNS servers to obtain the information.
What are the contents of the file /etc/resolv.conf on both servers?
Steven.

There is only 1 server, so the NS server is same. I guess its because
of diferrent time when the query was made.
But what was the result of the query that makes this error and
who/which server should responsible for this error :)
Thanks.

The result was what you originally posted to this mailing list.
The DNS server is responsible for the answer it gave, but I have no idea
what caused the error.

The postfix is _not_ running chrooted. All "n" in master.cf
In fact, this domain was working few days back and just after I
receive the complaint, it works by resending the email.
I still wondering, what answer given by my DNS that causing this error?
[root]# cat /etc/resolv.conf
nameserver 203.153.97.42
nameserver 203.153.118.10
nameserver 202.154.1.2
I forget, what was the original posting?

Does the file /var/spool/postfix/etc/resolv.conf file exist?
What is the last read access time?
Wietse
No. It does not.

Thanks.
Then you need to check the file permission of / /etc /etc/resolv.conf
or any other file that's needed for host lookup.
Directories need read and execute permission for NON-ROOT USERS,
files need read permission for NON-ROOT USERS.
Then test the host lookup as an NON-ROOT USER.
If that fails, see if if you're running Apparmor of some other
security enhancing feature that breaks legitimate applications.
Wietse
Forget it.
I need to see the output from dig for the host in question.

But anyway, the mail was succesfuly delivered after I ask the user to
re-send it.
--beast
In that case the DNS problem was temporary.
Wietse
But if the DNS problem was temporary, why postfix gives permanent
error and not simply retry on the next cycle?
The error CODE was permanent. The host did not exist in DNS.
The error CAUSE was not. Someone fixed it.
