rfc1912 2.4 CNAME records

Don't use CNAMEs in combination with RRs which point to other names
like MX, CNAME, PTR and NS.  (PTR is an exception if you want to
implement classless in-addr delegation.)  For example, this is
strongly discouraged:
           podunk.xx.      IN      MX      mailhost
           mailhost        IN      CNAME   mary
           mary            IN      A       1.2.3.4
