Ahem.

The message-id is required for transfer of a posted message from one
system to another.  However, when feeding an article to the mini-inews,
the message-id is NOT required since the posting isn't done yet - in
this respect, the Pnews->mini-inews->nntpd->inews is acting over the
network precisely as Pnews->inews would on a local system - inews is
expected to provide the message-id if there isn't one in the message
already.

If you're using a news system whose inews doesn't behave in this
manner, you have to use a poster that supplies the message-id itself.
I suppose that Pnews wouldn't work with your inews in a non-network
environment either; if that is the case, I don't see any reason for you
to be surprised that it fails when the message is transported by an
NNTP "POST" command instead of a pipe.
