       NNTP server process


       nntpd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
           [ -s ] [ -r ] [ -f ] [ -p ssf ]


       nntpd  is  an  NNTP  server. It accepts commands on its standard input and responds on its
       standard output. It MUST invoked by master(8) with those descriptors attached to a  remote
       client connection.

       nntpd  reads  its  configuration  options  out  of the imapd.conf(5) file unless specified
       otherwise by -C.  The optional newsprefix setting specifies a prefix to  be  prepended  to
       newsgroup  names  to make the corresponding IMAP mailbox names.  The optional newspostuser
       setting specifies the special userid to be used when constructing the To:  header  address
       for  following up to articles when read via IMAP.  The optional newspeer setting specifies
       the fully qualified hostname of the upstream news server to which articles are  fed.   The
       optional allownewnews setting enables the NNTP NEWNEWS command.

          For servers with a large volume of articles, the NEWNEWS command can be expensive.

       If  the  directory  <configdirectory>/log/user  exists,  then  nntpd  will create protocol
       telemetry logs for sessions authenticating as user. The telemetry logs will be  stored  in
       the log/user directory with a filename of the nntpd process-id.


       -C config-file
              Use   the   specified  configuration  file  config-file  rather  than  the  default

       -U uses
              The maximum number of times that the process should be  used  for  new  connections
              before shutting down.  The default is 250.

       -T timeout
              The  number  of  seconds  that  the  process  will wait for a new connection before
              shutting down.  Note that a value of  0  (zero)  will  disable  the  timeout.   The
              default is 60.

       -D     Run external debugger specified in debug_command.

       -s     Serve  NNTP  over  SSL  (https).  All data to and from nntpd is encrypted using the
              Secure Sockets Layer.

       -r     Only allow NNTP reader  commands.   Permitted  clients  will  only  be  allowed  to
              read/post articles.

       -f     Only  allow  NNTP  feeder commands.  Permitted clients will only be allowed to feed
              articles (no reading).

       -p ssf Tell nntpd that an external layer exists.  An SSF (security strength factor)  of  1
              means  an  integrity  protection layer exists.  Any higher SSF implies some form of
              privacy protection.
