If you don't specify ND, incoming files  will be sent in PUNCH format and
cut  at column  80.  I  only require  outgoing  support  for Netdata  for
backbone status, as the jobs don't go through the mailers and are sent in
Netdata format  anyway. But of  course I advise having  a Netdata-capable
production mailer and registering ND in :serversN.
