Does pdns (or will pdns) have the ability to provide a different response
based on the querying IP?

i.e. If I have one LAN with a workstation on .100 and a mail server on .25,
and I port forward port 25 on my firewall in to .25...

Can I tell pdns to respond with .25 if queried from the LAN, and the
external IP address if queried from the outside?

(Something in me says that this might be disallowed by RFC, but I'm not
sure.  Just thought I'd pipe up and ask.)
