        A CNAME *must not* point to a CNAME.  (So tells DNS standard.)
        The target for CNAME must be A/AAAA, and/or MX.

        Some MTAs allow recursion on CNAME resolution, but
        they limit it at about 2-3 recursions.
        (Once I saw a case of
                A CNAME C
                C CNAME B
                B CNAME C
         and I noticed it after my MTA had crashed, when it
         ran over the stack in the recursion loop..)
