You have to use force_actions to add a message with selectors.

Maybe give this a try (untested):

  REJECT_MIME_BAD {
    action = "reject";
    expression = "FILE_EXTENSION_BLACKLISTED";
    # message can contain selector expressions enclosed in ${}
    message = "attachment type ${symbol('FILE_EXTENSION_BLACKLISTED',
'options')} not allowed";
  }
