dig axfr <zonelist> | tr '[A-Z]' '[a-z]' | awk '$4 == "CNAME" && $5 == "myserver."'
With perl you could collaps the tr and awk commands into one command.
If you have a really large zone list you could put it in a file and have
named read it.
dig axfr -f zonelist | tr '[A-Z]' '[a-z]' | awk '$4 == "CNAME" && $5 == "myserve."'
Note: this does not cover CNAME -> CNAME.
