Errm, yes. I looked in the octal column...

Ok, ok, any brown paper bags lying around? Should learn to read before

It's certainly ok to accepted broken header lines (in the RFC 1036
defined broken) from the upstream. But if a user posts an article to
leafnode with broken headers, leafnode should refuse this article with a
meaningful error message, so that the users knows there's something
wrong. Otherwise the article may get lost in failed.postings when the
upstream refuses to accept it.
	Any big blunders in this observation?
