news, nntp and snews
The news, nntp, and snews schemes, defined in RFC
1738, are used for reading Usenet newsgroups. For compatibility with
non-standard-compliant news clients, the url library allows
host and port fields to be included in news URLs, even though
they are properly only allowed for nntp and snews.
news and nntp URLs have the following form:
The default port for nntp (and news) is 119. The
difference between an nntp URL and a news URL is that an
nttp URL may specify an article by its number. The
‘snews’ scheme is the same as ‘nntp’, except that it is
tunneled through SSL and has default port 563.
These URLs are retrieved via the Gnus package.
This variable specifies the default news server from which to fetch news, if no server was specified in the URL. The default value,
nil, means to use the server specified by the standard environment variable ‘NNTPSERVER’, or ‘news’ if that environment variable is unset.
