Well, you should understand that PowerDNS Recursor's main purpose is
to *recurse*. If configure forward-zones, then that is already the
'exclusion' on what to recurse. With "forward-zones=.=8.8.8.8" you
basically turn off recursion.

Taking one step back to answer your question, I believe you may be
using the wrong tool to do the job. Consider using dnsdist (which is
an advanced forwarder) and configure it to forward queries to your
upstream recursor, excluding some domains. I think the page on Server
pools [1] should get you started on how to handle certain domains
differently.
