SERVFAIL <=> NXDOMAIN

[Irenäus Becker]

Hello,

we encountered a problem with registry nic.at for tld .at and their 
transaction "BillWithDraw". This transaction allows an registrar to 
delegate authority back to registry.
For a successful use of this transaction all nameserver-entries for the 
zone will be deleted by our application before nic-order will be sent to 
nic.at.
Nic.at now checks all nameserver for existing entries for affected zone. 
If all nameservers return a NXDOMAIN (Bind) everything is fine.
Our NSD nameservers return the status SERVFAIL. Nic.at interprets this 
return-code as an error and does not finish this transaction completely.

Is it possible to return a NXDOMAIN instead of a SERVFAIL? Are there 
different  possibilities how this point can be resolved?
Nic.at will not change their behaviour before Q4!

Best regards,
Irenäus Becker
