Nntpd reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C. The optional newsprefix option specifies a prefix to be prepended to newsgroup names to make the corresponding IMAP mailbox names. The optional newspostuser option specifies the special userid to be used when contructing the To: header address for following up to articles when read via IMAP. The optional newspeer option specifies the fully qualified hostname of the upstream news server to which articles are fed. The optional allownewnews option enables the NNTP NEWNEWS command. NOTE: For servers with a large volume of articles, the NEWNEWS command can be expensive.
If the directory log/user exists under the directory specified in the configdirectory configuration option, 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.

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