recursive service and forward

[Michael]

I'd like to know if there is a way to configure BIND so that a server 
with this configuration:

zone "myzone.com" in {
  type forward;
  forward only;
  forwarders {
    1.2.3.4 port 1234;
  }
}

will supply recursive service?

The purpose for this... I'm running a dnsbl where the active records are 
maintained and modified on a continual basis by a number of different 
daemons and processes that run independently. It is possible for this set 
of processes to answer an axfr request from bind, but the zone file is 
immense and for the bind daemon to stay current would consume large 
resources. Having bind operate as forward only provides caching and 
robust service to the "outside" without the need to maintain a zonefile. 
So.... how does one configure bind to do this. I guess the question is 
how to get bind to respond authoratatively for this zone. Is this doable 
with the current distribution or a potential "feature" request.
