When I try to post an article through nnrpd in inn-2.3.2-5 with two "Cc"
headers, it says:
441 Duplicate "Cc" header
and rejects the article. While it's true that there are some Usenet
headers which can't be duplicated, "Cc" isn't one of them, especially since
it doesn't have any real significance in a Usenet article (it appears in my
article because I'm both posting and mailing the same message). This is
therefore an inappropriate reason to reject an article.
Here is an answer from INN upstream:

So I'll close it as WONTFIX, you're the only one who's complaining for it.
