No outgoing mail when BIND9 is off

Hello, I have debian 4.0 and the newest Version of Virtualmin pro and webmin installed on a minimal configuration Debian 4. Everything is working. Only with Postfix i have a problem with outgoing mails. Receiving is working well. I don't want to use Bind because my server-prodiver also has DNS servers.

The Problem is when is turn BIND off i get deferred (Host or domain name not found. Name service error for name=gmx.net type=MX: Host not found, try again)

When BIND server is on everything is workin fine. I Hope someone can help me [size=4] Mail Log:[/size]

the nameservers in resolv.conf are the ones given by my provider. They are reachable from my server.

For example when i test: servername:/etc# host gmx.net gmx.net has address 213.165.65.50 gmx.net mail is handled by 10 mx0.gmx.net. gmx.net mail is handled by 10 mx0.gmx.de. outbreak-eve:/etc# they seem to work with bind9 = off.

Here is my postfix config. Maybe it helps you. Please tell me if you need something.
