Per,
I just want to throw in the following:
In case you want to subdelegate a part of a PTR zone, this seems to be the
recommended way to do it:

Postfix certainly does as:
$ dig +short 50.131.144.213.in-addr
According to RFC1034 and 2181, a PTR record using a CNAME is not
permitted. I believe this to still be correct, postfix certainly
doesn't work with a CNAME when it does a reverse lookup.
Any comments?
