Can you elaborate a bit more? I think this issue is ""fixed"" in 3.3, which contains a change that makes PowerDNS be a bit more lenient in understanding CNAME chains containing SOA records that indicate a 'NO ERROR' response. 3.3-rc2 can be found on http://svn.powerdns.com/release-candidates/ The relevant item is: Deal better with UltraDNS style CNAME redirects containing SOA records. Spotted by Andy Fletcher from UKDedicated in ticket 303, fix in commit 1628. http://wiki.powerdns.com/projects/trac/ticket/303 http://wiki.powerdns.com/projects/trac/changeset/1628 Let me know if this solves your problem.
