Simon,

I see that you are back and wanted to bring this up again. We are using
DNSMasq within AWS to perform DNS whitelisting and I noticed that there is
no log line produced when a domain is NOT configured to be forwarded. I
think this patch should take care of it and would love to have it
considered.
