AIUI, most news servers (including INN and CNews) provide two interfaces:

'inews' - please inject this article (does some rather thorough format checks);
'rnews' - please relay this article (does the minimum amount of checks
          that it can get away with).

"minimum amount" probably includes the basic NNTP requirements
(essentially that the header fields can be separated out) and also enough
to disentangle the headers it needs to look at (which is most of the
mandatory ones).

OTOH, if the 'rnews' is also going to store the article locally (it is
then a serving agent as well as a relaying agent), then it probably needs
to do somewhat more (indeed USEPRO says it MUST).
