Inews reads an article from either each of the specified files in turn or standard
input, adds the required and specified header lines and passed it to
rnews(8) with the
-h option is given the input is assumed to be in the form of header, blank line
If not then it is all treated as the article body.
If any header line is specifed as a command line argument then the command
line contents override that read from the input.
If any of the header lines that are required by RFC 1036 are then missing
they are added with default content.
If the content
From header line is overridden either from standard input with the
-h option or with the
-f option and the posting user is not the
news user then a
Sender header line is added.
