^^^^ you have a CNAME record for ftp.WHATEVER.DOM ,a TXT and
      a RP record.
This will give you "CNAME and other data" error and should be logged.

- Either you want the TXT and RP records belonging to the
   domain record itself.
   * move the records above the CNAME records.
   * Or move an "at" character '@' at the start of the TXT record like
@                IN      TXT     "Location: Yann's Office"

- If you want the RP an TXT records to be part of the
   ftp.WHATEVER record, you cannot use a CNAME.

- Explanation: When there is no label at the start of a line,
   the label (name) is inherited from the last label seen above
   the record. In this case the label (name) for the TXT and RP
   records will be ftp.WHATEVER.DOM
