Nntpd is a 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 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.
