Default DNS lookups do not work with postfix in jail
Hello

I'm currently having difficulties with postfix running on FreeBSD 9 in a jail. I set up the jail and postfix and everything should be running fine. But my problem is that DNS lookups do not work in postfix-restrictions.

When I send a mail to the server for relaying it to the outside world I always get lines like the following in /var/log/maillog:
Code:
Jul  2 11:17:08 andenes postfix/smtpd[1982]: NOQUEUE: reject: RCPT from unknown[192.168.199.11]:
450 4.1.2 <MYACCOUNT@gmail.com>: Recipient address rejected: 
Domain not found; from=<MYSENDER@brain-force.ch> to=<MYACCOUNT@gmail.com> proto=ESMTP helo=<narvik.local>
and mail is rejected.

But if I perform the nslookup directly from command line then I get a positive answer
Code:
andenes# dig gmail.com +short
173.194.35.22
173.194.35.21
My DNS server (BIND) is running in a seperate jail on the same FreeBSD machine.
I put the DNS server in /etc/resolv.conf of the jail and it looks as follows
Code:
search local
nameserver 192.168.200.201
nameserver 8.8.8.8
.201 is the named machine.

Any ideas what could be "broken"?

thanks a lot

tobi
