Capitalized letters in newsgroup names are a problem because it is
not strictly defined whether newsgroup names should be case-sensitive
or not.

Son-of-RFC1036 defines the content of the Newsgroups: header as

          Newsgroup names MUST not contain uppercase  letters,  except
          where required by encodings in encoded words.

It says, however:

               NOTE: Possibly newsgroup names  should  have  been
               case-insensitive, but all existing software treats
               them as case-sensitive.   (RFC  977  [rrr]  claims
               that they are case-insensitive in NNTP, but exist-
               ing implementations are believed to ignore  this.)
               The simplest solution is just to ban use of upper-
               case letters, since no widespread  newsgroup  name
               uses  them  anyway; this avoids any possibility of

Most servers where I encountered the problem so far (e.g.
news.microsoft.de) did treat newsgroup names indeed as case-
insensitive; therefore 1.9.4 (in contrast to 1.9.2) did so as well.
Apparently, INN does not like this:

There is no easy way to fix this in leafnode-1.9.4; it might be
necessary to downgrade to 1.9.2.
