Using nsupdate when I try to delete an MX record for a domain, I get REFSUED.
REFUSED is also reported when attempting to update a non-dynamic zone. Are you sure the zone you're trying to update is actually dynamic?
How do I remove and replace the MX record for a domain with nsupdate?
del ownernamne. MX [rdata] should do it. Without [rdata] all MX for the owner will be removed, but specify rdata to indicate you wish to delete just the one.
