[Pdns-users] Strange CNAME behavoir

This is normal behaviour, for the simple reason that a CNAME record is
intended to be a redirection.
The algorithm is the following: if you have a question to the name server
([record name] + [type]), the server checks if [record name] has a CNAME
entry, and if it does then re-asks the question with the canonical name of
So example.com + SOA becomes example.org + SOA.
The consequence of this behaviour is that if you have a CNAME for [record
name], all the other entries for [record name] will be ignored, since the
redirection will bypass them.
If this is not clear enough, you should read the relevant RFCs.
