Could you show me the reason why tcprelay is not good for AXFR relay?
I personally have not encountered a situation where DNS over TCP is
necessary.  It is the reason why it has not been implemented.

DNS-DeleGate can reads hosts file (or NIS hosts) to provide the data
to DNS clients.  You can specify any hosts file other than /etc/hosts
as RESOLV="file:/path/of/hosts".  Not only A record, also it can serve
MX record by defining "-MX.hostname xx.xx.xx.xx" in hosts file.

So far, the policy of DNS-DeleGate is to be as simple as possible in
its implementation and configuration, while satisfying minimum
functionality for common usage.  
I'm rather conservative about what should be extended to it because,
of course, there are complete implementations of DNS server in the
world if complete solution is necessary.
