Exchange 2007 451 4.4.0 DNS query failed

I just setup an exchange 2007 sp1 server and installed the rollup updates. I can receive email but not send it.
My queue has the 451 4.4.0 DNS query failed  error all over the place.  I can pull up cmd and ping anything and get name resolution just fine.

Any ideas?

I think you need to check on your DNS configuration.

nevermind I'm an idiot!  That's what I get for staying up all night working on this email server.  I forgot to set the DNS forwarders in my DNS servers to my ISP's DNS servers!!!
