Hi Retro Guy,

This information is always sent by INN and cannot be deactivated.

A news client is not supposed to do that.  The data following the 340 
and 240 codes are just comments, with no special meaning defined by the 
NNTP protocol.  See the example in RFC 3977:

       [C] POST
       [S] 340 Input article; end with <CR-LF>.<CR-LF>
       [C] From: "Demo User" <nobody@example.net>
       [C] Newsgroups: misc.test
       [C] Subject: I am just a test article
       [C] Organization: An Example Net
       [C]
       [C] This is just a test article.
       [C] .
       [S] 240 Article received OK


If a news client wants to parse the comments for possible Message-IDs as 
INN and maybe other news servers provide them, let's trust the developer 
to implement it right and take the one of the 240 response.  That would 
otherwise be a bug in the implementation.
And if not implemented, you don't mind.
