       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 imapd.conf(5).

       -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.
