Internal vs. External DNS/Domain Separation Question

[Justin Piszcz]

Hello,

I have two domains:
1) internal (call it .int)
2) external (my domain)

I use bind9 for internal forward/reverse dns and for the external, forward 
dns only.

When my mail server does dns lookups it looks up not only the domain in 
question, in this example, RBL checks, but it also appends my 
internal domain (tries to lookup the address within the scope of my 
domain):

14-Sep-2008 05:31:18.745 client 192.168.0.1#52380: query: 98.243.165.206.vote.drbl.balakovo.ru IN A +
14-Sep-2008 05:31:18.746 client 192.168.0.1#42269: query: 98.243.165.206.vote.drbl.be.net.ru IN A +
14-Sep-2008 05:31:18.747 client 192.168.0.1#40672: query: 98.243.165.206.openlists.orbs.org.int IN A +
14-Sep-2008 05:31:18.748 client 192.168.0.1#46048: query: 98.243.165.206.dnsbl.sorbs.net.int IN A +

So there are 2 lookups for every dns lookup (one for domainA and one for 
domainA.int)..  I have tried utilizing views but that did not seem to fix 
the problem.  I have tried commenting out the "search int" in all clients &
servers for /etc/resolv.conf, that did not solve the issue.

Is this normal operation with bind or is there a way to separate this out 
properly with views, such that:

1. External DNS lookups only query the actual IP in question and they do 
not query my local internal domain name?
2. Also, I should be able to keep "search int" in /etc/resolv.conf and not 
have it try to perform external DNS lookups and append the .int?

Is this possible?

Justin.
