Injection-Date and Injection-Info in nnrpd

RFC 3977:
   [IHAVE] differs from the POST command in that it is intended
   for use in transferring already-posted articles between hosts.  It
   SHOULD NOT be used when the client is a personal news-reading
   program, since use of this command indicates that the article has
   already been posted at another site and is simply being forwarded
   from another host.


Besides, IHAVE in nnrpd already behaves like this.  For instance,
a post without a message-ID will be rejected by nnrpd when using IHAVE.
It is the same for a post without a Path: header.

When I say "wrong", I mean that it is an invalid date (something that
cannot be parsed as a date).  So I believe the issue you report will
not occur.

In fact, my remark was more because of that paragraph in RFC 5537:

        It SHOULD reject any article whose
        Injection-Date header field is too far in the past (older than
        the cutoff interval of a relaying agent that the injecting agent
        is using, for example).  It SHOULD similarly reject any article
        whose Date header field is too far in the past, since not all
        news servers support Injection-Date and only the injecting agent
        can provide a useful error message to the posting agent.

We still follow the second SHOULD.  Note that it partly defeats what
Injection-Date is for, because I can write an article the 4th and
send it the 24th.  My Injection-Date is the 24th, which is the real
date of the article, according to RFC 5537:

       (In the following discussion, the
       "date" of an article is defined to be the date represented by its
       Injection-Date header field, if present; otherwise, by its Date
       header field.)
